The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 18.89% of the average value of its portfolio.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of consumer companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, consumer companies include those engaged in producing or selling goods or services to consumers. Examples include producers of food, beverages, apparel, household and leisure goods, cars and related items, media content, operators of retails stores, and companies offering services to private consumers. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the consumer sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Consumer Discretionary and Consumer Staples Sectors.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk:Because the Fund's investments are concentrated in Chinese securities and in the consumer sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please seeRisks Related to Investing in China, Risks Related to Investing in the Consumer Discretionary Sector, and Risks Related to Investing in the Consumer Staples Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk: China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Consumer Discretionary Sector: The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Risks Related to Investing in the Consumer Staples Sector: The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the energy and utilities sectors, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China, Risks Related to Investing in the Energy Sector, and Risks Related to Investing in the Utilities Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder
purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price
is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Energy Sector: The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in energy prices; international politics; energy conservation; the success of exploration projects; natural disasters or other catastrophes; changes in exchange rates, interest rates, or economic conditions; changes in demand for energy products and services; and tax and other governmental regulatory policies.

Risks Related to Investing in the Utilities Sector:Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of financials companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, financials companies include those engaged in banking, lending, insurance, investments and/or financing. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the financials sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the financials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Financials Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Financials Sector: Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. Chinese financial sector regulation and ownership may be more intrusive than in the United States and other developed countries, especially with respect to the regulation of non-Chinese banks and other non-Chinese financial companies. Greater Chinese governmental involvement in the financial sector may pose additional risks for investors. Market conditions in China may be particularly subject to change based on government policy. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10.61% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of industrials companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, industrials companies include those engaged in heavy construction, production of construction materials, waste and water management, freight transportation or production and manufacturing of industrial goods, vessels, vehicles, containers, electrical equipment and machinery. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the industrials sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Industrials Sector.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the industrials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Industrials Sector. 

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Industrials Sector: Investments in securities in the industrials sector are subject to fluctuations in supply and demand for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrials sector. Companies also may be adversely affected by environmental damage and product liability claims.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13.51% of the average value of its portfolio.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of materials companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, materials companies include those engaged in developing, producing or selling physical substances and raw materials. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the materials sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the materials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Materials Sector. 

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Materials Sector: Investments in securities in the materials sector are subject to changes in commodity prices, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in mid-market capitalization ("mid cap") securities on companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, the Fund considers mid-cap companies to be those companies included in, or similar in size to those included in, the Solactive China Mid Cap Index, as of the latest reconstitution date, at the time of purchase. As of January 1, 2015 the market capitalization of the Solactive China Mid Cap Index was between $500 million and $15 billion. The Fund’s capitalization range will change over time. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the investable universe of Chinese mid-market capitalization companies, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China. 

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk:Mid cap companies may have greater volatility in price than the stocks of large companies due to limited product lines or resources or a dependency upon a particular market niche.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities of technology companies that are domiciled in, principally traded in or whose revenues are primarily from China. For purposes of this policy, technology companies include those engaged in production of technology-related hardware and software, telecommunications, internet, information technology and social media. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to track the performance of the technology sector in China as defined by The NASDAQ OMX Group, Inc. ("NASDAQ"), the provider of the Underling Index ("Index Provider"). It is made up of securities of companies which have their main business operations in the technology sector and generally includes companies whose businesses involve: computer services; internet; software; computer hardware; electronic office equipment; semiconductors; and telecommunications equipment. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Technology Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the technology sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Technology Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:China has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in China:Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China.

Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Risks Related to Investing in the Technology Sector: Investments in securities in the technology sector are subject to rapid changes in technology product cycles; rapid product obsolescence; government regulation; and increased competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology tend to be more volatile than the overall market, and are also are heavily dependent on patent and intellectual property rights.

Securities Market Risk:Because certain securities markets in China are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in China are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 18.59% of the average value of its portfolio.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of consumer companies that are domiciled in, principally traded in or whose revenues are primarily from Brazil. For purposes of this policy, consumer companies include producers of food, beverages, apparel, household and leisure goods, cars and related items, media content, operators of retail stores, and companies offering services to private consumers. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the consumer sector of the Brazilian economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Consumer Discretionary and Consumer Staples Sectors.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Brazil.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk:The Fund invests in Brazilian securities, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Brazilian economy.

Concentration Risk: Because the Fund's investments are concentrated in Brazilian securities and in the consumer sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Brazil, Risks Related to Investing in the Consumer Discretionary Sector, and Risks Related to Investing in the Consumer Staples Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Brazil is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder
purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price
is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Risks Related to Investing in the Consumer Discretionary Sector: The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Risks Related to Investing in the Consumer Staples Sector: The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

SUMMARY OF PRINCIPAL RISKS

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk:The Fund invests in Brazilian securities, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Brazilian economy.

Concentration Risk: Because the Fund's investments are concentrated in Brazilian securities and the financials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Brazil and Risks Related to Investing in the Financials Sector.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Brazil is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund had not yet commenced investment operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also will invest at least 80% of its total assets in securities of industrials companies that are domiciled in, principally traded in or whose revenues are primarily from Brazil. For purposes of this policy, industrials companies include those engaged in heavy construction, production of construction materials, waste and water management, freight transportation or production and manufacturing of industrial goods, vessels, vehicles, containers, electrical equipment and machinery. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the industrials sector of the Brazilian economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Brazil.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk:The Fund invests in Brazilian securities, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Brazilian economy.

Concentration Risk: Because the Fund's investments are concentrated in Brazilian securities and in the industrial sector, the Fund will be susceptible to losses due to adverse occurrences affecting this country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Brazil.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Brazil is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk: The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Risks Related to Investing in the Industrials Sector: Companies in the industrials sector are affected by supply and demand both for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrial sector. Companies may also be adversely affected by environmental damage and product liability claims.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also will invest at least 80% of its total assets in securities of materials companies that are domiciled in, principally traded in or whose revenues are primarily from Brazil. For purposes of this policy, materials companies include those engaged in developing, producing or selling physical substances and raw materials. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the materials sector of the Brazilian economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Brazil.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk:The Fund invests in Brazilian securities, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Brazilian economy.

Concentration Risk: Because the Fund's investments are concentrated in the Brazilian securities and in the materials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Brazil is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk: The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Brazil. For purposes of this policy, the Fund considers mid-market capitalization ("mid-cap") companies to be those companies included in, or similar in size to those included in, the Solactive Brazil Mid Cap Index, as of the latest reconstitution date, at the time of purchase. As of January 1, 2015, the market capitalization of the Solactive Brazil Mid Cap Index was between $1 billion and $13 billion. The Fund’s capitalization range will change over time. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the Brazilian mid-market capitalization companies, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in any industry.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Concentration Risk: Because the Fund's investments are concentrated in Brazilian securities and in the mid-cap size category, the Fund will be susceptible to losses due to adverse occurrences affecting this country and asset class. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Brazil.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market.

You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk:Mid cap companies may have greater volatility in price than the stocks of large companies due to limited product lines or resources or a dependency upon a particular market niche.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder
purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price
is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk:The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also will invest at least 80% of its total assets in securities of utilities companies that are domiciled in, principally traded in or whose revenues are primarily from Brazil. For purposes of this policy, utilities companies include those engaged in the operation of facilities that distribute utilities such as electricity, natural gas, telecommunications, water, sewage and engage in related services. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the utilities sector of the Brazilian, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Brazil.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk:The Fund invests in Brazilian securities, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Brazilian economy.

Concentration Risk: Because the Fund's investments are concentrated in the Brazilian securities and in the utilities sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Currency Risk:Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Brazil's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Brazil is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Brazil, which could affect the economy or particular business operations of companies economically tied to Brazil.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:The economy of Brazil is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk:Brazil has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk: The Fund invests in the Brazilian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Brazil:Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund's investments.

Risks Related to Investing in the Utilities Sector:Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets.

Securities Market Risk:Because the securities markets in Brazil are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Brazil are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk:A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on Brazil's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economies of Chile, Colombia and Peru.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk: The Fund invests in the Chile, Colombia and Peru markets, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on these economies.

Concentration Risk: Because the Fund's investments are concentrated in Chilean, Colombian and Peruvian securities and the financials sector, the Fund will be susceptible to losses due to adverse occurrences affecting these countries and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Andean Region and Risks Related to Investing in the Financials Sector.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Andean currencies depreciate against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: The Fund is expected to invest in securities in the following emerging market countries: Chile, Colombia and Peru. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk: Several countries in Europe are major trade and investment partners of Chile, Colombia and Peru. Decreasing imports or exports, changes in governmental or Economic and Monetary Union of the European Union (the “EMU”) regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EMU member country or its sovereign debt, and recessions in an EMU member country may have a significant adverse effect on the economies of EMU member countries and their trading partners.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in South America, which could affect the economy or particular business operations of companies economically tied to South America.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk: High interest rates, economic volatility, inflation, currency devaluations, fluctuations in commodity prices, government defaults and high unemployment rates in Central or South America may have an adverse impact on the economies of Chile, Colombia and Peru.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitlization Companies Risk:Mid cap companies may have greater volatility in price than the stocks of large companies due to limited product lines or resources or a dependency upon a particular market niche.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder
purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price
is at a discount to the NAV, the shareholder may sustain losses.

Reliance on Trading Partners Risk: Economies in emerging market countries generally are dependent heavily upon commodity prices and international trade and, accordingly, may be affected adversely by the economies of their trading partners, trade barriers, exchange controls, managed adjustments in relative currency values, and may suffer from extreme and volatile debt burdens or inflation rates.

Risks Related to Investing in the Andean Region: The Fund currently invests in the Andean countries of Chile, Colombia and Peru. The economies of these countries have experienced periods of high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the regions' exports, and many economies in this region are particularly sensitive to fluctuations in commodity prices.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Security Risk: Countries in which the Fund invests have experienced security concerns. Incidents involving a country's or region's security may cause uncertainty in the country's markets and may adversely affect its economies and the Fund's investments.

Structural Risk:The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosures rates may have an adverse impact on the economies of Chile, Colombia and Peru.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, the Fund invests at least 80% of its total assets in securities that are economically tied to Argentina. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to represent the performance of the broad Argentina equity universe, while including a minimum number of constituents, as defined by MSCI, Inc. ("MSCI"), the provider of the Underlying Index ("Index Provider"). The broad Argentina equity universe includes securities that are classified in Argentina according to the MSCI Global Investable Market Index Methodology, together with companies that are headquartered or listed in Argentina and carry out the majority of their operations in Argentina. The Underlying Index targets a minimum of 25 securities and 20 issuers at construction. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Energy Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Argentina.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Argentinian securities and in the energy sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country or market. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Argentina and Risks Related to Investing in the Energy Sector.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Argentina's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Argentina is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risks: Frontier market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The economies of frontier market countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier market countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk: A natural disaster could occur in Argentina, which could affect the economy or particular business operations of companies economically tied to Argentina.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk: The economy of Argentina is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk: Argentina has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk: The Fund invests in the Argentinean economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economies in which the Fund invests.

Risks Related to Investing in Argentina: Argentina has experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. The economy is heavily dependent on exports and commodities. Argentina’s default on its debt in 2001, and its recent nationalization of private pensions, continues to impact the confidence of investors in Argentina, which might adversely impact returns in the Fund. In 2014, minority bondholders of Argentina’s previously defaulted debt sought, and won, an injunction that prohibited Argentina from repaying bonds that had been renegotiated, unless they simultaneously paid the holdout minority bondholders their full amount due as well. Argentina’s willingness and ability to repay its sovereign debt is currently in question, and the possibility of default is not unlikely, which could limit its ability to borrow in the future.

Risks Related to Investing in the Energy Sector: The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in energy prices; international politics; energy conservation; the success of exploration projects; natural disasters or other catastrophes; changes in exchange rates, interest rates, or economic conditions; changes in demand for energy products and services; and tax and other government regulatory policies.

Securities Market Risk: Because the securities markets in Argentina are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Argentina are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosures rates may have an adverse impact on the economy of Argentina.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

²    Index performance reflects the performance of the FTSE Argentina 20 Index through August 14, 2014 and the MSCI All Argentina 25/50 Index thereafter. Effective August 15, 2014, the Fund changed its index from the FTSE Argentina 20 Index to the MSCI All Argentina 25/50 Index ("New Index"). This change was effected due to the planned migration to the New Index, potentially allowing for broader access to the local market.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8.36% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Singapore, Malaysia, Indonesia, Thailand and the Philippines. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index tracks the equity performance of the 40 largest and most liquid companies in the five Association of Southeast Asian Nations ("ASEAN") regions: Singapore, Malaysia, Indonesia, Thailand and the Philippines, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Singapore, Malaysia, Indonesia, Thailand and the Philippines.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions partially for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk: The Fund invests in securities and markets that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on these economies.

Concentration Risk: Because the Fund's investments are concentrated in ASEAN related securities and in the financials sector, the Fund will be susceptible to losses due to adverse occurrences affecting these countries or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the ASEAN Region and Risks Related to Investing in the Financials Sector.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the ASEAN currencies depreciate against the U.S. dollar.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: The Fund is expected to invest in securities in the following emerging market countries: Malaysia, Indonesia, Thailand and the Philippines. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Southeast Asia, which could affect the economy or particular business operations of companies economically tied to Southeast Asia.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder

purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price

is at a discount to the NAV, the shareholder may sustain losses.

Reliance on Trading Partners Risk: Economies in emerging market countries generally are dependent heavily upon commodity prices and international trade and, accordingly, may be affected adversely by the economies of their trading partners, trade barriers, exchange controls, managed adjustments in relative currency values, and may suffer from extreme and volatile debt burdens or inflation rates.

Risks Related to Investing in the ASEAN Region: Investments in the ASEAN region involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. Singapore, Malaysia, Thailand, Indonesia and the Philippines present different economic and political conditions from those in Western markets, and less social, political and economic stability. In the past, some of these economies have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosures rates may have an adverse impact on the economies of Singapore, Malaysia, Indonesia, Thailand and the Philippines.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund had not yet commenced investment operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Bangladesh, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Bangladesh.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Bangladeshi securities, the Fund will be susceptible to losses due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Bangladesh.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Bangladesh's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Bangladesh is an emerging market country which, may be subject to a greater risk of loss than investments in developed markets.Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risks: Frontier market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The economies of frontier market countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier market countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk: A natural disaster could occur in Bangladesh, which could affect the economy or particular business operations of companies economically tied to Bangladesh.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Privatization Risk: Bangladesh has privatized certain entities and industries. Privatized entities may lose money or be renationalized.

Risks Related to Investing in Bangladesh: Investments are concentrated in companies in Bangladesh. Bangladesh faces many economic hurdles including weak political institutions, government mismanagement of resources, poor infrastructure, lack of privatization of industry and a labor force that has outpaced job growth in the country. The privatization of industries in Bangladesh has been slow, largely due to worker unrest at state-owned enterprises. Opposition from government bureaucracy and public sector unions has prevented much of the economic liberalization, and capital markets in Bangladesh are still in need of reform with regard to the treatment of foreign investors and foreign capital.

Securities Market Risk: Because securities markets in Bangladesh are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Bangladesh are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Security Risk: The country in which the Fund invests has experienced security concerns. Incidents involving a country's or region's security may cause uncertainty in Colombian markets and may adversely affect their economies and the Fund's investments.

Structural Risk: Colombia may be subject to considerable degrees of economic, political and social instability.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests its total assets in securities of companies that are listed on the Colombian Stock Exchange as well as cash and cash equivalents. The Fund also invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The investment policies described above are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance in Colombia, as defined by MSCI, Inc. ("MSCI"), the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”).

Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Colombia and Risks Related to Investing in the Financials Sector.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Colombia's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Colombia is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Colombia, which could affect the economy or particular business operations of companies economically tied to Colombia.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk: The economy of Colombia is affected by the economies of Latin American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk: Mid-market capitalization companies may have greater volatility in price than the stocks of large companies due to limited product lines or resources or a dependency upon a particular market niche.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder

purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price

is at a discount to the NAV, the shareholder may sustain losses.

Reliance on Trading Partners Risk: The Fund invests in the Colombian economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests.

Risks Related to Investing in Colombia: Investment in Colombian issuers and companies that have significant operations in Colombia involves risks that are specific to Colombia, including legal, regulatory, political and economic risks. The Colombian economy has grown steadily during the past several years, but there can be no assurance that economic growth will continue. The Colombian economy depends heavily on oil, coal and other commodity exports, making it vulnerable to commodity prices.

Risks Related to Investing in the Financials Sector: Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk: Because the securities markets in Colombia are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Colombia are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Security Risk: The country in which the Fund invests has experienced security concerns. Incidents involving a country's or region's security may cause uncertainty in Colombian markets and may adversely affect their economies and the Fund's investments.

Structural Risk: Colombia may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosures rates may have an adverse impact on the economy of Colombia.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from "Next Emerging and Frontier" markets, which are defined generally as investable markets that have lower market capitalization and less liquidity than more developed markets. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect equity performance of Next Emerging markets and Frontier markets companies, as defined by the Solactive AG, the provider of the Underlying Index ("Index Provider"). Next Emerging markets are defined as emerging market countries beyond the BRICs (Brazil, Russia, India and China are excluded) and beyond the most developed tier of emerging markets (currently South Korea and Taiwan are also excluded). Frontier markets are those emerging market countries that generally have smaller economies or less developed capital markets. The Underlying Index is comprised of common stocks, ADRs and GDRs of selected companies globally that are domiciled, principally traded in or have their main business operations in these markets or that generate at least 50% of their revenues from these markets. The Underlying Index screens the largest stocks according to free-float market capitalization, which may include small- or mid-cap companies, and weights them by modified liquidity.

As of January 1, 2015, the Underlying Index had 201 constituents from the following countries: Argentina, Bangladesh, Chile, Colombia, Czech Republic, Egypt, Gabon, Georgia, Hungary, Indonesia, Kazakhstan, Kenya, Kuwait, Laos, Malaysia, Mauritius, Mexico, Mongolia, Namibia, Nigeria, Oman, Pakistan, Panama, Papua New Guinea, Peru, Philippines, Poland, Qatar, Slovakia, South Africa, Tanzania, Thailand, Turkey, United Arab Emirates and Vietnam. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund uses a representative sampling strategy with respect to the Underlying Index. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in a sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

African Economic Risk: Investment in African securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asian Economic Risk: Investments in Asian markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. The countries in Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk: Unlike most ETFs, the Fund intends to effect all creations and redemptions partially for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Commodity Exposure Risk: The Fund invests in securities and markets that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on these economies.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if relevant foreign currencies depreciates.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: The Fund’s investments in emerging market countries may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risks: Frontier market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The economies of frontier market countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier market countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk: A natural disaster could occur in a country in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk: Many economies in Latin America have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region's exports and many economies in this region, are particularly sensitive to fluctuations in commodity prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Middle East Economic Risk: Certain economies in the Middle East depend to a significant degree upon exports of primary commodities such as oil. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Countries in the Middle East may be affected by political instability, war or the threat of war, regional instability, terrorist activities and religious, ethnic and/or socioeconomic unrest. Recent unrest and instability in the larger Middle East region has adversely impacted many economies in the region. Recent political instability and protests in the Middle East and North Africa (which has ethnic, religious and economic ties to the Middle East) have caused significant disruptions to many industries.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder

purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk: The countries in which the Funds invest have privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Securities Market Risk: Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk: Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities on companies that are domiciled in, principally traded in or whose revenues are primarily from Greece. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index is designed to reflect broad-based equity market performance in Greece, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

Risk [Heading]

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Greek securities and in the financials sector, the Fund will be susceptible to losses due to adverse occurrences affecting that country or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Greece and Risks Related to Investing in the Financials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the euro depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Greece is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Greece, which could affect the economy or particular business operations of companies economically tied to Greece.

Government Debt Risk: Greece currently has high levels of debt and public spending, which may stifle economic growth, contribute to prolonged periods of recession or lower Greece’s sovereign debt rating and adversely impact investments in the Fund.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Financials Sector: Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Risks Related to Investing in Greece: Investments are concentrated in companies in Greece. Greece’s economy is heavily dependent on the services sector and has a large public sector. Key trading partners are member states of the European Union ("EU"), most notably Germany, Spain, Italy and the United Kingdom. Decreasing demand for Greek products and services or changes in governmental regulations on trade may have a significantly adverse effect on Greece’s economy. Greece’s ability to repay its sovereign debt is in question, and the possibility of default is not unlikely, which could limit its ability to borrow in the future. Greece has been required to impose harsh austerity measures on its population in order to receive financial aid from the IMF and EU member countries. The success of political parties in Greece opposed to austerity measures may increase the possibility that Greece would rescind these austerity measures and consequently fail to receive further financial aid from these institutions. The persistence of these factors may seriously reduce the economic performance of Greece and pose serious risks for the country’s economy in the future. There is the possibility that Greece may exit the European Monetary Union, which would result in immediate devaluation of the Greek currency and potential for default. If this were to occur, Greece would face significant risks related to the process of full currency redenomination as well as the resulting instability of the Euro zone in general, which would have a severe adverse effect on the value of the securities held by the Fund. Increased volatility in the Greek market may result in the increased use of fair value pricing.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk: Because securities markets in Greece are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Greece are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Sweden, Denmark, Norway and Finland. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to reflect broad-based equity market performance in Sweden, Denmark, Norway and Finland, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). The Index tracks the equity performance of the 30 largest and most liquid companies in Sweden, Denmark, Norway and Finland. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in Sweden, Norway, Finland and Denmark, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on the economies of Sweden, Norway, Finland and Denmark.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Nordic Region and Risks Related to Investing in the Financials Sector.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Nordic currencies depreciate against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Sweden, Denmark, Norway and Finland, which could affect the economies or particular business operations of companies economically tied to Sweden, Denmark, Norway and Finland.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Financials Sector: Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Risks Related to Investing in the Nordic Region: Investments are concentrated in companies in Sweden, Denmark, Norway and Finland. The Nordic economies are heavily dependent on natural resources, trade amongst one another and with the members of the European Union, and have historically generous welfare programs.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because the securities markets in certain countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in these countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Norway. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance in Norway, as defined by MSCI, Inc. ("MSCI"), the provider of the Underlying Index ("Index Provider"). The Underlying Index consists of stocks traded primarily on the Norwegian stock exchange. The Underlying Index may include large-, mid- or small-capitalization companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Energy Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in Norway, which is susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on the economy of Norway.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Norway and Risks Related to Investing in the Energy Sector.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Norway's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Norway, which could affect the economy or particular business operations of companies economically tied to Norway.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Norway: Investments in Norwegian issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks specific to Norway. Norway is a major producer of oil and gas, and Norway's economy is subject to the risk of fluctuations on oil and gas prices. The high value of the Norwegian krone as compared to other currencies could have a damaging effect on Norwegian exports and investments. In recent years, labor costs in Norway have increased faster than those of its major trading partners, eroding industrial competitiveness.

Risks Related to Investing in the Energy Sector:The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in energy prices; international politics; energy conservation; the success of exploration projects; natural disasters or other catastrophes; changes in exchange rates, interest rates, or economic conditions; changes in demand for energy products and services; and tax and other government regulatory policies.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Securities Market Risk: Because the securities markets in Norway are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Norway are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

²    Index performance reflects the performance of the FTSE Norway 30 Index through July 14, 2014 and the MSCI Norway IMI 25/50 Index thereafter. Effective July 15, 2014, the Fund changed its index from FTSE Norway 30 Index to the MSCI Norway IMI 25/50 Index ("New Index"). This change was effected due to the planned migration to the New Index, potentially allowing for broader access to the local market.

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities on companies that are domiciled in, principally traded in or whose revenues are primarily from Portugal.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index is designed to reflect broad-based equity market performance in Portugal, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Portuguese securities and the utilities sector, the Fund will be susceptible to losses due to adverse occurrences affecting that country or market. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Portugal and Risks Related to Investing in the Utilities Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the euro depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in Portugal, which could affect the economy or particular business operations of companies economically tied to Portugal.

Government Debt Risk: Portugal currently has high levels of debt and public spending, which may stifle economic growth, contribute to prolonged periods of recession or lower Portugal’s sovereign debt rating and adversely impact investments in the Fund.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Portugal: Investments are concentrated in companies in Portugal. Portugal’s economy is comprised of several sectors but is heavily dependent on the services sector. Decreasing demand for Portuguese products and services or changes in governmental regulations on trade may have a significantly adverse effect on Portugal’s economy. The long-term credit assessment is not favorable for Portugal, and serious problems persist with regard to public finances and excessive debt levels.

Risks Related to Investing in the Utilities Sector: Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk: Because securities markets in Portugal are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Portugal are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund had not yet commenced investment operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Czech Republic, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

Risk [Heading]

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Czech Republic securities and the industrials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Czech Republic and Risks Related to Investing in the Industrials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the euro depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: The Czech Republic is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in Czech Republic, which could affect the economy or particular business operations of companies economically tied to Czech Republic.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Czech Republic: Investments are concentrated in companies in the Czech Republic. The Czech Republic’s economy is heavily dependent on the manufacturing and export of industrial materials and machinery. The Czech Republic and surrounding regions have a history of ethnic unrest and conflict. If conflict were to renew in the future, it could have a significant adverse impact on the Fund.

Risks Related to Investing in the Industrials Sector: Investments in securities in the industrials sector are subject to fluctuations in supply and demand for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrials sector. Companies also may be adversely affected by environmental damage and product liability claims.

Securities Market Risk: Because securities markets in the Czech Republic are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in the Czech Republic are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 54.75%.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Nigeria, as defined by MSCI, Inc. ("MSCI"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 23 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Consumer Staples and Financials Sectors.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

African Economic Risk: Investment in African securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transaction Risk:Unlike most ETFs, the Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Nigerian securities and the consumer and financials sectors, the Fund will be susceptible to losses due to adverse occurrences affecting that country or sectors. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Nigeria, Risks Related to Investing in the Consumer Sector, and Risks Related to Investing in the Financials Sector.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Nigerian currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risk: Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Geographic Risk: A natural disaster could occur in Nigeria, which could affect the economy or particular business operations of companies economically tied to Nigeria.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder

purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price

is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk: Nigeria has privatized certain entities and industries. Privatized entities may lose money or be re-nationalized.

Risks Related to Investing in Nigeria: Investments are concentrated in companies in Nigeria. The economic development of Nigeria has been significantly hindered by military rule, mismanagement, corruption and ethnic conflict. The Nigerian economy is heavily dependent on oil, and the industry makes up a significant portion of Nigeria’s GDP. Religious and social conflict is present in Nigeria, often resulting in the outbreak of violence, particularly in the Niger Delta, which is Nigeria’s main oil-producing region. Nigeria also suffers from the prevalence of organized crime and corruption, which makes it more difficult for citizens and companies to do business in Nigeria and has significant impact on the Nigerian economy. The persistence of organized crime and corruption may continue to drag on economic growth in the country. Outbreaks of communicable diseases in the region may impair Nigeria’s economic growth. Nigeria has imposed capital controls to varying degrees in the past, which may make it more difficult to invest in companies in Nigeria or repatriate currency and which may negatively impact long-term investment.

Risks Related to Investing in the Consumer Staples Sector: The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Risks Related to Investing in the Oil Sector: The oil industry is cyclical and highly dependent on the market price of oil. The market value of companies in the oil industry are strongly affected by the levels and volatility of global oil prices, oil supply and demand, capital expenditures on exploration and production, energy conservation efforts, the prices of alternative fuels, exchange rates and technological advances. Companies in this sector are subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget restraints may have a material adverse effect on the stock prices of companies in the industry.

Securities Market Risk: Because securities markets in Nigeria are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Nigeria are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

²    Index performance reflects the performance of the Solactive Nigeria Index through August 14, 2014 and the MSCI All Nigeria Select 25/50 Index thereafter. Effective August 15, 2014, the Fund changed its index from Solactive Nigeria Index to the MSCI All Nigeria Select 25/50 Index ("New Index"). This change was effected due to the planned migration to the New Index, potentially allowing for broader access to the local market.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities on companies that are domiciled in, principally traded in or whose revenues are primarily from Pakistan. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to represent the performance of the broad Pakistan equity universe, while including a minimum number of constituents, as defined by MSCI, Inc. ("MSCI"), the provider of the Underlying Index ("Index Provider"). The broad Pakistan equity universe includes securities that are classified in Pakistan according to the MSCI Global Investable Market Index Methodology, together with companies that are headquartered or listed in Pakistan and carry out the majority of their operations in Pakistan. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of Pakistan.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund intends to effect all creations and redemptions principally for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Pakistan securities, the Fund will be susceptible to loss due to adverse occurrences affecting this country or market. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Pakistan.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Pakistani currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Pakistan is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risks: Frontier market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The economies of frontier market countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier market countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk: A natural disaster could occur in Pakistan, which could affect the economy or particular business operations of companies economically tied to Pakistan.

Government Debt Risk: Pakistan currently has high levels of debt and public spending, which may stifle economic growth, contribute to prolonged periods of recession or lower Pakistan’s sovereign debt rating and adversely impact investments in the Fund.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Middle East Economic Risk: Pakistan and other Middle Eastern markets are only in the earliest stages of development and may be considered "frontier markets." Certain economies in the Middle East depend to a significant degree upon exports of primary commodities such as oil. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Countries in the Middle East may be affected by political instability, war or the threat of war, regional instability, terrorist activities and religious, ethnic and/or socioeconomic unrest. Recent unrest and instability in the larger Middle East region has adversely impacted many economies in the region. Recent political instability and protests in the Middle East and North Africa (which has ethnic, religious and economic ties to the Middle East) have caused significant disruptions to many industries.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Pakistan: Pakistan’s economy is heavily dependent on exports and subject to high interest rates, economic volatility, inflation, currency devaluations, high unemployment rates and high level of debt and public spending. There is also the possibility of nationalization, expropriation or confiscatory taxation, security market restrictions, political changes, government regulation or diplomatic developments (including war or terrorist attacks), which could affect adversely the economy of Pakistan or the value of the Fund’s investments. As an emerging country, Pakistan’s economy is susceptible to economic, political and social instability; unanticipated economic, political or social developments could impact economic growth. Pakistan is also subject to natural disaster risk. In addition, recent political instability and protests in the Middle East have caused significant disruptions to many industries. Continued political and social unrest in these areas may negatively affect the value of your investment in the Fund. Pakistan has recently seen elevated levels of ethnic and religious conflict, in some cases resulting in violence or acts of terrorism. Escalation of these conflicts would have an adverse effect on Pakistan’s economy.

Securities Market Risk: Because the securities markets in Pakistan are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Pakistan are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Central Asian countries of Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Energy and Materials Sectors.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economies of Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Central Asian securities and the energy and materials sectors, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or sectors. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Central Asia, Risks Related to Investing in the Energy Sector, and Risks Related to Investing in the Materials Sector.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if any Central Asian currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk:Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risks: Frontier market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The economies of frontier market countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier market countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk: A natural disaster could occur in Central Asia, which could affect the economy or particular business operations of companies economically tied to Central Asia.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk: The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price of fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk:Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder
purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price
is at a discount to the NAV, the shareholder may sustain losses.

Risks Related to Investing in Central Asia: Investments are concentrated in companies in Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries in Central Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. In addition, the ability of companies to efficiently conduct their business activities in Central Asia is subject to changes in government policy or shifts in political attitudes within countries in the region. Any adverse change in the relationship with major trading partners such as China, or significant economic or political turmoil in China itself, may also have a significant negative impact on the financial markets in Central Asia.

Risks Related to Investing in the Energy Sector:The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in energy prices; international politics; energy conservation; the success of exploration projects; natural disasters or other catastrophes; changes in exchange rates, interest rates, or economic conditions; changes in demand for energy products and services; and tax and other government regulatory policies.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Market Risk:Because the securities markets in certain countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in these countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15.77% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are economically tied to the copper mining industry. Companies economically tied to the copper mining industry include those engaged in copper mining and/or closely related activities such as exploration and refining. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance of global companies involved in the copper mining industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 23 constituents, 19 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in copper miners, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on copper miners.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Copper Exploration Industry, Risks Related to Investing in the Copper Mining Industry and Risks Related to Investing in the Materials Sector.

Copper Price Relationship Risk: The Underlying Index measures the performance of companies involved in the copper mining industry and not the performance of the price of copper itself. The securities of companies involved in the copper mining industry may under- or over-perform the price of copper itself over the short-term or the long-term.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets copper mining companies globally and is expected to invest in securities in emerging market countries, currently including China, Mexico, Poland, and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund targets copper mining companies globally and is expected to invest in securities in foreign countries, currently including Australia, Canada, China, Mexico, Switzerland, Poland, South Africa, and the United Kingdom, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets copper mining companies globally and is expected to invest in securities in geographic regions currently including North America, Europe, Asia, and Australia, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Copper Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Copper Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the copper mining industry and the price of copper itself. The price of copper may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of copper may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, copper mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer.

The Underlying Index is designed to track the performance of the largest listed companies globally that are active in some aspect of the fertilizer/potash industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 23 constituents, 16 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in companies that are economically tied to the fertilizers/potash industry, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the fertilizers/potash industry.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Fertilizer/Potash Exploration Industry, Risks Related to Investing in the Fertilizer/Potash Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets fertilizer companies globally and is expected to invest in securities in emerging market countries, currently including China, South Korea, Taiwan, and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund targets fertilizer companies globally and is expected to invest in securities in foreign countries, currently including Australia, Brazil, Canada, Chile, China, Germany, Israel, Norway, Russia, South Korea, Switzerland, Taiwan and Turkey, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets fertilizer companies globally and is expected to invest in securities in geographic regions currently including Asia, Europe, and North America, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Fertilizer Commodities Prices Relationship Risk: The Underlying Index measures the performance of companies involved in the fertilizer industry and not the performance of fertilizer commodities themselves. The securities of companies involved in the fertilizer industry may under- or over-perform fertilizer commodities prices over the short-term or the long-term.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Fertilizers/Potash Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Fertilizers/Potash Mining Industry: Economic forces, including forces affecting the agricultural commodity, energy and financial markets, as well as government policies and regulations affecting the agricultural sector and related industries, could adversely affect the Fund’s portfolio companies and, thus, the Fund’s returns. Agricultural production and trade flows are significantly affected by government policies and regulations. In addition, the Fund’s portfolio companies must comply with a broad range of environmental laws and regulations which could adversely affect the Fund. Additional or more stringent environmental laws and regulations may be enacted in the future and such changes could have a material adverse effect on the business of the Fund’s portfolio companies.

Securities in the Fund’s portfolio also may be significantly subject to the effects of competitive pressures in the fertilizer industry and the price of fertilizer commodities. The price of fertilizer may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of fertilizer may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, fertilizer companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Market Risk: Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets are invested in securities that are economically tied to the gold exploration industry. Companies economically tied to the gold exploration industry include those engaged in the exploration of gold mining projects. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is free float-adjusted, liquidity-tested and market capitalization-weighted index that is designed to measure broad-based equity market performance of global companies involved in gold exploration, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 19 constituents, 16 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in companies that are economically tied to the gold exploration industry, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the gold exploration industry.

To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in theGold Exploration Industry, Risks Related to Investing in the Gold Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets gold exploration companies globally and is expected to invest in securities in emerging market countries. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund is expected to invest in securities in foreign countries, currently including Canada, Australia and China, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets gold exploration companies globally and is expected to invest in securities in geographic regions currently including North America, and Australia, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Gold Price Relationship Risk: The Underlying Index measures the performance of companies primarily involved in gold exploration and not the performance of the price of gold itself. The securities of companies involved in gold exploration may not be correlated with the performance of the price of gold itself and may under- or over-perform the performance of the price of gold itself over the short-term or the long-term.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Gold Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Gold Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the gold mining industry and the price of gold bullion. The price of gold may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. A significant portion of the world’s gold reserves are held by governments, central banks and related institutions. If one or more of these institutions sold their holdings of gold in significant quantities, it could cause gold prices to fall. The price of gold may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, gold mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 27.75% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are economically tied to the small-capitalization mining industry. Companies economically tied to the small-capitalization mining industry include those engaged in mining, producing, smelting, and/or refining materials, including but not limited to coal, copper, gold, iron, nickel, silver, titanium and other materials. For the purposes of this policy, the Fund considers small market capitalization companies to be those companies included in, or similar in size to those included in, the Solactive Global Junior Miners Index, as of the latest reconstitution date, at the time of purchase. As of January 1, 2015, the market capitalization of the Solactive Global Junior Miners Index was between $40 million and $2.5 billion. The Fund’s capitalization range may change over time. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to track the market performance of small-capitalization mining companies globally, as defined by the Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 98 constituents, 77 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in junior mining companies, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on junior miners.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in theJunior Exploration Industry, Risks Related to Investing in the Junior Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets companies economically tied to the small-cap mining industry and is expected to invest in securities in emerging market countries, currently including Brazil, China, Indonesia, Russia, South Africa and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund is expected to invest in securities in foreign countries, currently including Australia, Belgium, Brazil, Canada, China, Indonesia, Ireland, Japan, Russia, South Africa, Turkey, and the United Kingdom, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets junior mining companies globally and is expected to invest in securities in geographic regions currently including Africa, Asia, Europe, North America and South America, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Junior Mining Relationship Risk: The Underlying Index measures the performance of small-capitalization companies involved in the mining industry and not the performance of commodities themselves. The securities of small-capitalization companies involved in the mining industry may under- or over-perform commodities themselves over the short-term or the long-term.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Mining Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Risks Related to Investing in the Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the mining industry and the price of commodities mined. The price of commodities may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of commodities may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In particular, a drop in the price of a given commodity could adversely affect the profitability of small-capitalization mining companies and their ability to secure financing. In addition, mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 43.37% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are economically tied to the lithium industry. Companies economically tied to the lithium industry include those engaged in lithium mining and lithium battery production. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance of global companies involved in the lithium industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 23 constituents, 17 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in lithium companies, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on lithium companies.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Lithium Exploration Industry, Risks Related to Investing in the Lithium Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including Chile, China, South Korea and Taiwan, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Exposure to Non-Lithium Markets Risk: Although the Fund invests a large percentage of its assets in the securities of companies that are active in the exploration and/or mining of lithium, these companies may derive a significant percentage of their profits from other business activities including, for example, the production of fertilizers and/or specialty and industrial chemicals. As a result, the performance of these markets and the profits of these companies from such activities may significantly impact the Fund’s performance.

Foreign Security Risk: The Fund is expected to invest in securities in foreign countries, currently including Canada, France, Australia, Japan, Taiwan, South Korea and China, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets companies economically tied to the lithium industry and is expected to invest in securities in geographic regions currently including North America, Europe, Australia and Asia, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Lithium Price Relationship Risk: The Underlying Index measures the performance of companies involved in the lithium mining and lithium-ion battery industries and not the performance of the price of lithium itself. The securities of companies involved in the lithium industry may under- or over-perform the price of lithium itself over the short-term or the long-term.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Lithium-Ion Battery Industry: Securities in the Fund’s portfolio involved in the manufacturing of lithium-ion batteries are subject to the effects of price fluctuations of traditional and alternative sources of energy, developments in battery and alternative energy technology, the possibility that government subsidies for alternative energy will be eliminated and the possibility that lithium-ion technology is not suitable for widespread adoption.

Risks Related to Investing in the Lithium Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Lithium Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the lithium mining industry and the price of lithium. The price of lithium may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of lithium may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, lithium mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24.23% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are economically tied to the silver mining industry. Companies economically tied to the silver mining industry include those engaged in silver mining and/or closely related activities such as exploration and refining. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance of global companies involved in the silver mining industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 22 constituents, 12 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Materials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in silver miners, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on silver miners.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Silver Exploration Industry, Risks Related to Investing in the Silver Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets silver mining companies globally and is expected to invest in securities in emerging market countries, currently including Mexico, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets.Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund targets silver mining companies globally and is expected to invest in securities in foreign countries, currently including Canada, Mexico, and the United Kingdom, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets silver mining companies globally and is expected to invest in securities in geographic regions currently including North and South America and Europe, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Risks Related to Investing in the Silver Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Silver Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the silver mining industry and the price of silver bullion. The price of silver may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of silver may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, silver mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Silver Bullion Relationship Risk: The Underlying Index measures the performance of companies involved in the silver mining industry and not the performance of the price of silver bullion itself. The securities of companies involved in the silver mining industry may under- or over-perform the price of silver bullion over the short-term or the long-term.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are active in some aspect of the uranium mining industry such as mining, refining, exploration, or manufacturing of equipment for the uranium industry. The Fund may also invest in companies that do not derive a significant percentage of revenues from activities related to the uranium industry, but generate large absolute revenues from the uranium mining industry (in particular uranium mining, exploration for uranium, physical uraniun investments and technologies related to the uranium industry). The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure broad-based equity market performance of global companies involved in the uranium industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 21 constituents, 16 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in uranium companies, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on uranium companies.

Concentration Risk: In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or sectors or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Uranium Exploration Industry, Risks Related to Investing in the Uranium Mining Industry and Risks Related to Investing in the Materials Sector.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund targets uranium mining companies globally and invest in securities in emerging market countries. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Exposure to Non-Uranium Markets Risk: Although the Fund invests a large percentage of its assets in the securities of companies that are active in the exploration and/or mining of uranium, these companies may derive a significant percentage of their profits from other business activities including, for example, physical uranium investments and technologies related to the uranium industry. As a result, the performance of these markets and the profits of these companies from such activities may significantly impact the Fund's performance.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: The Fund targets uranium mining companies globally and is expected to invest in securities in foreign countries, currently including Canada, Australia, and France, a list that might be expanded as the Underlying Index rebalances over time. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: The Fund targets uranium mining companies globally and is expected to invest in securities in geographic regions currently including North America, Australia and Europe, a list that might change as the Underlying Index rebalances over time. A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Micro-Capitalization Companies Risk:The Fund may invest in micro-capitalization companies. Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Materials Sector:Companies in the materials sector are affected by commodity price volatility, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Risks Related to Investing in the Uranium Exploration Industry: The exploration and development of mineral deposits involve significant financial risks over a significant period of time, which even a combination of careful evaluation, experience and knowledge may not eliminate. Few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to establish reserves by drilling and to construct mining and processing facilities at a site. In addition, mineral exploration companies typically operate at a loss and are dependent on securing equity and/or debt financing, which might be more difficult to secure for an exploration company than for a more established counterpart.

Risks Related to Investing in the Uranium Mining Industry: Securities in the Fund’s portfolio may be significantly subject to the effects of competitive pressures in the uranium mining industry and the price of uranium. The price of uranium may be affected by changes in inflation rates, interest rates, monetary policy, economic conditions and political stability. The price of uranium may fluctuate substantially over short periods of time, therefore the Fund’s Share price may be more volatile than other types of investments. In addition, uranium mining companies may also be significantly affected by import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

The primary demand for uranium is from the nuclear energy industry, which uses uranium as fuel for nuclear power plants. Demand for nuclear energy may face considerable risk as a result of, among other risks, incidents and accidents, breaches of security, ill-intentioned acts or terrorism, air crashes, natural disasters (such as floods or earthquakes), equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Uranium Price Relationship Risk: The Underlying Index measures the performance of companies involved in the uranium industry and not the performance of the price of uranium itself. The securities of companies involved in the uranium industry may under- or over-perform the price of uranium itself over the short-term or the long-term.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index tracks the performance of 100 equally-weighted companies that rank among the highest dividend yielding equity securities in the world, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Financials Sector.

Credit Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if currencies of the underlying securities depreciate against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including Brazil, Chile, China, Czech Republic, Poland, South Africa, South Korea, Taiwan, and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Because certain securities markets in the emerging countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

High Dividend Yield Stocks Risk: High-yielding stocks are often speculative, high risk investments. These companies can be paying out more than they can support and may reduce their dividends or stop paying dividends at any time, which could have a material adverse effect on the stock price of these companies and the Fund’s performance.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Prepayment Risk: When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.

Risks Related to Investing in Mortgage Real Estate Investment Trusts: Mortgage real estate investment trusts (“REITs”) are exposed to the risks specific to the real estate market as well as credit risk, interest rate risk, leverage risk and prepayment risk.

Risks Related to Investing in Real Estate Stocks and Real Estate Investment Trusts: The Fund may invest in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 40.04% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index. The Fund also invests at least 80% of its total assets in dividend-yielding U.S. securities. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index tracks the performance of 50 equally-weighted common stocks including Master Limited Partnerships ("MLPs") and Real Estate Investment Trust ("REITs") that rank among the highest dividend yielding equity securities in the United States, as defined by INDXX, LLC, the provider of the Underlying Index ("Index Provider"). The components of the Underlying Index have paid dividends consistently over the last two years. The Underlying Index is comprised of securities that the Index Provider determines to have lower relative volatility, as measured by the beta of each security relative to the market benchmark. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund ("Adviser"). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Utilities Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Utilities Sector.

Credit Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

High Dividend Yield Stocks Risk: High yielding stocks are often speculative, high risk investments. These companies can be paying out more than they can support and may reduce their dividends or stop paying dividends at any time, which could have a material adverse effect on the stock price of these companies and the Fund’s performance.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk: The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Prepayment Risk: When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.

Risks Related to Investing in Master Limited Partnerships: Investments in the securities of MLPs involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, and cash flow risks. MLP common units and other equity securities can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment towards MLPs or the energy sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms of distributable cash flow). Prices of common units of individual MLPs and other equity securities also can be affected by fundamentals unique to the partnership or company, including earnings power and coverage ratios.

Risks Related to Investing in Mortgage Real Estate Investment Trusts: Mortgage real estate investment trusts (“REITs”) are exposed to the risks specific to the real estate market as well as credit risk, interest rate risk, leverage risk and prepayment risk.

Risks Related to Investing in Real Estate and Stocks Real Estate Investment Trusts: The Fund may invest companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the Utilities Sector: Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small- and Mid-Capitalization Companies Risk: Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund had not yet commenced investment operations as of the most recent fiscal year. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also may invest up to 20% of its total assets in derivatives such as futures contracts, options on future contracts, options and swaps, as well as cash, cash equivalents, and securities not included in the Underlying Index but which the Global X Management Company, LLC, the investment adviser to the Fund ("Adviser") believes will assist the Fund in tracking the performance of its Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index seeks to preserve and increase its value, over the long term, through risk balancing across asset classes as defined by FXcube Strategies LLC, the provider of the Underlying Index ("Index Provider"). The Underlying Index consists of multiple asset classes which may include bonds, equities, commodities, currencies and real estate. Exposure may include global developed and emerging markets.

In allocating assets among asset classes, the Underlying Index follows a “risk parity” approach. The “risk parity” approach to asset allocation seeks to balance the allocation of risk across asset classes (as measured by volatility) when building the Underlying Index. This means that lower risk asset classes (such as global fixed income and inflation-linked government bonds) will generally have higher notional allocations than higher risk asset classes (such as global developed and emerging market equities). The Underlying Index rebalances quarterly as it aims to keep the risk contribution of each asset in the portfolio equal.

The Fund may gain exposure to different asset classes by investing in many different types of instruments including, but not limited to, equity securities, equity futures, currency forwards, swaps on currency forwards, swaps on indexes, commodity futures, swaps on commodity futures, bond futures, swaps on bond futures, corporate and government bonds, including inflation protected government bonds, cash and cash equivalents. The Fund may also invest in U.S. and foreign exchange-traded vehicles, including exchange traded funds (“ETFs”), exchange traded commodities (“ETCs”) or exchange traded notes (“ETNs”) through which the Fund can participate in the performance of one or more asset classes.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Underlying Index is calculated and maintained by Solactive AG.

The Adviser will use a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The Fund uses a representative sampling strategy with respect to the Underlying Index. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes. Even if the Underlying Index seeks to preserve and increase its value over the long term, it is subject to the risk of suffering substantial short-term declines from time to time, which would also result in substantial losses for the Fund.

Commodities Regulatory Risk: The Commodity Futures Trading Commission ("CFTC") may repropose regulations that may limit the use of commodity interests by the Fund. Any changes in regulations could affect the Fund’s ability to pursue its investment program as described in this Prospectus.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Counterparty Risk: Counterparty risk is the risk that a counterparty to a swap contract or other similar investment instrument may default on its payment obligation to the Fund. Such a default may cause the value of an investment in the Fund to decrease.

Credit Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value.

Currency Risk: The Fund may invest in foreign currencies, which are subject to risks, which include changes in the debt level and trade deficit of the country issuing the foreign currency; inflation rates of the United States and the country issuing the foreign currency; investors’ expectations concerning inflation rates; interest rates of the United States and the country issuing the foreign currency; investors’ expectations concerning interest rates; investment and trading activities of mutual funds, hedge funds and currency funds; and global or regional political, economic or financial events and situations.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Derivatives Risk: The Fund may gain exposure to different asset classes by investing in different types of derivative instruments including, but not limited to, equity futures, currency forwards, swaps on currency forwards, swaps on indexes, commodity futures, swaps on commodity futures, bond futures, and swaps on bond futures. Derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses for the Fund. In addition, the prices of the derivative instruments and the prices of underlying securities, interest rates or currencies they are designed to reflect may not move together as expected. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with its Underlying Index.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries. Because certain securities markets in the emerging countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Forward and Futures Contract Risk: The primary risks associated with the use of forward and futures contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) the possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) the possibility that the counterparty will default in the performance of its obligations; and (d) the possibility that, if the Fund has insufficient cash, the Fund may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

High Yield Securities Risk: Securities that are rated below investment grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-“ by Standard & Poor’s® (a division of the McGraw-Hill Companies, Inc.) (“S&P”) and Fitch, Inc. (“Fitch), “Baa3” by Moody’s® Investors Service, Inc. (“Moody’s”), or “BBBL” by Dominion Bond Rating Service Limited (“Dominion”)), or are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, may be more volatile than higher-rated securities of similar maturity.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Foreign Investment Company Risk: Some Fund holdings may be characterized as “passive foreign investment companies” ("PFICs") for U.S. tax purposes. Because the application of the PFIC rules may affect, among other things, the character of gains and the amount of gain or loss and the timing of the recognition of income with respect to PFIC shares, and may subject the Fund itself to tax on certain income from PFIC shares, the amount that must be distributed to shareholders and will be taxed to shareholders as ordinary income or long-term capital gain may be increased or decreased substantially as compared to a fund that did not invest in PFIC shares.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Prepayment Risk: When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.

Risks Related to Investing in Bonds: Investments in debt securities are generally affected by changes in prevailing interest rates and the creditworthiness of the issuer. Prices of debt securities fall when prevailing interest rates rise. The Fund’s yield on investments in debt securities will fluctuate as the securities in the Fund are rebalanced and reinvested in securities with different interest rates. Investments in bonds are also subject to credit risk. Credit risk is the risk that an issuer of debt securities will be unable to pay principal and interest when due, or that the value of the security will suffer because investors believe the issuer is less able to make required principal and interest payments. This is broadly gauged by the credit ratings of the debt securities in which the Fund invests. However, credit ratings are only the opinions of the rating agencies issuing them, do not purport to reflect the risk of fluctuations in market value and are not absolute guarantees as to the payment of interest and the repayment of principal.

RisksRelated to Investing in Commodity-Related Instruments: The Fund may invest in commodity ETFs and/or ETCs. Exposure to commodities may subject the Fund to greater volatility than investments in traditional securities. The value of commodities may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments.

Risks Related to Investing in ETCs: The Fund may hold ETCs to gain exposure to physical gold and commodities. As a result, the Fund may be subject to the same risks as the underlying ETCs. While the risks of owning shares of an underlying ETC generally reflect the risks of owning the underlying metals the ETC holds, lack of liquidity in an underlying ETC can result in its value being more volatile than the metals themselves. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETCs. ETCs that invest in physical gold may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, ETCs are not registered under the ("1940 Act") and, therefore, are not subject to the regulatory scheme and investor protections of the Investment Company Act of 1940.

Risks Related to Investing in ETFs:The Fund may hold ETFs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETFs. While the risks of owning shares of an underlying ETF generally reflect the risks of owning the underlying securities of the index the ETF is designed to track, lack of liquidity in an underlying ETF can result in its value being more volatile than the underlying portfolio securities. Because the value of other ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund’s holdings in those shares at the most optimal time, thereby adversely affecting the Fund’s performance. In addition, ETF shares may trade at a premium or discount to net asset value.

In addition, investments in the securities of other ETFs may involve duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs, which could result in greater expenses to the Fund. By investing in another ETF the Fund becomes a shareholder thereof. As a result, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses indirectly paid by shareholders of the other ETF, in addition to the fees and expenses Fund shareholders indirectly bear in connection with the Fund’s own operations.

If the other ETF fails to achieve its investment objective, the value of the Fund’s investment will decline, adversely affecting the Fund’s performance. ETFs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, some ETFs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act.

Risks Related to Investing in ETNs: The Fund may hold ETNs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETNs. An ETN may trade at a premium or discount to its net asset value. The Fund will indirectly bear its pro rata share of the fees and expenses incurred by an ETN it invests in, including advisory fees, and will pay brokerage commissions in connection with the purchase and sale of shares of ETNs. ETNs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this prospectus. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer’s credit rating, and any payments on an ETN by an issuer is subject to the issuer's ability to pay its obligations as they become due.

Risks Related to Investing in Gold-Related Instruments: The Fund may invest in ETFs and/or ETCs that invest in physical gold. Gold generates no interest or dividends, and the return from investments in gold will be derived solely from the price gains or losses from the commodity. Gold may also be significantly affected by developments in the gold mining industry, and prices of gold may fluctuate sharply over short periods of time. Income derived from gold (or ETFs or ETCs investing in physical gold) is generally not qualifying income for purposes of the “regulated investment company” (“RIC”) diversification tests under the Internal Revenue Code of 1986, as amended (the “Code”). In August 2011, the Internal Revenue Service (“IRS”) announced that it would stop issuing private letter rulings authorizing favorable tax treatment for funds that invest indirectly in commodities or derivatives based upon commodities such as gold and silver. The IRS has previously issued a number of private letter rulings to funds in this area, concluding that such investments generate “qualifying income” for RIC qualification purposes. It is unclear how long this suspension will last. The IRS has not indicated that any previously issued rulings in this area will be affected by this suspension. This suspension of guidance by the IRS means that the tax treatment of such investments is now subject to some uncertainty.

Risks Related to Investing in Inflation-LinkedBonds: The Fund may invest in inflation-linked bonds, which are income-generating instruments whose interest and principal payments are adjusted for inflation – a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

Risks Related to Investing in Real Estate Stocks and Real Estate Investment Trusts:The Fund may invest in an underlying fund that invests in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Volatility Risk: The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant appreciations or decreases in value over short periods of time.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index tracks the equity performance of the largest and most liquid companies involved in the social media industry, including companies that provide social networking, file sharing, and other web-based media applications, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 30 constituents, 7 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Technology Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in the social media industry, the Fund will be susceptible to loss due to adverse occurrences affecting this industry. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Technology Sector.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including China and Taiwan, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Because certain securities markets in the emerging countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Social Media Industry: The Fund invests in securities of companies engaged in the social media industry, including companies that provide social networking, file sharing, and other web-based media applications. The risks related to investing in such companies include disruption in service caused by hardware or software failure, interruptions or delays in service by third-party data center hosting facilities and maintenance providers, security breaches involving certain private, sensitive, proprietary and confidential information managed and transmitted by social media companies, and privacy concerns and laws, evolving Internet regulation and other foreign or domestic regulations that may limit or otherwise affect the operations of such companies. Furthermore, the business models employed by the companies in the social media industry may not prove to be successful.

Risks Related to Investing in the Technology Sector: Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is comprised of the top U.S. listed equity positions reported on Form 13F by a select group of entities characterized as hedge funds, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider").

Hedge funds are selected from a pool of thousands of privately offered pooled investment vehicles based on the size of their reported equity holdings and the efficacy of replicating their publicly disclosed positions. Hedge funds must have minimum reported holdings of $500 million in their Form 13F to be considered for the Underlying Index. Additional filters are applied to eliminate hedge funds that have high turnover rates for equity holdings. Only hedge funds with a concentrated top holding are included in the selection process.

Once the hedge fund pool has been determined, the Index Provider utilizes Form 13F filings to compile the top stock holding from each of these hedge funds. The stocks are screened for liquidity, equal weighted, and rebalanced quarterly following the Form 13F filing timeline. As of January 1, 2015, the Underlying Index had 61 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Technology Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Technology Sector.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Form 13F Data:The Form 13F filings used to select the securities in the Underlying Index are filed up to 45 days after the end of each calendar quarter. Therefore a given investor may have already sold its position by the time the security is added to the Underlying Index. Furthermore, the Form 13F filing may only disclose a subset of a particular investor’s holdings, as not all securities are required to be reported on the Form 13F. As a result, the Form 13F may not provide a complete picture of the holdings of a given investor. An investor may hold long positions for a number of reasons, and the Index Provider has not investigated such reasons or the strategies followed by an investor who makes the filings.  The Underlying Index may not be representative of the investor's universe or the strategies that give rise to the reported holdings. Because the Form 13F filing is publicly available information, it is possible that other investors are also monitoring these filings and investing accordingly. This may result in inflation of the share price of securities in which the Fund invests. 

Risks Related to Investing in the Technology Sector: Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Securities Lending Risk: Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or of investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Turnover Risk: The Fund may experience relatively high portfolio turnover, which may result in increased transaction costs and lower Fund performance.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is comprised of U.S. listed equity positions reported on Form 13F by a select group of entities characterized as premier value investors, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider").

Value investors are selected from a universe of investors that aim to buy securities that appear undervalued based on fundamental analysis, as defined by the Index Provider. The Index Provider applies a number of criteria to narrow the pool of investors to a small group that has demonstrated an outstanding long-term performance track record. Value investors must have minimum reported holdings of $1 billion in their Form 13F to be considered for the Underlying Index.

Once the pool of value investors has been determined, the Index Provider utilizes Form 13F filings to compile the largest two position increases from each of these investors. Position increases are subject to minimum sizes to be considered. Positions will be sold when they decrease materially in subsequent 13F reports. The stocks are screened for liquidity, equal weighted, and rebalanced quarterly following the Form 13F filing timeline. As of January 1, 2015, the Underlying Index had 41 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Form 13F Data:The Form 13F filings used to select the securities in the Underlying Index are filed up to 45 days after the end of each calendar quarter. Therefore a given investor may have already sold its position by the time the security is added to the Underlying Index. Furthermore, the Form 13F filing may only disclose a subset of a particular investor’s holdings, as not all securities are required to be reported on the Form 13F. As a result, the Form 13F may not provide a complete picture of the holdings of a given investor. An investor may hold long positions for a number of reasons, and the Index Provider has not investigated such reasons or the strategies followed by an investor who makes the filings.  The Underlying Index may not be representative of the investor's universe or the strategies that give rise to the reported holdings. Because the Form 13F filing is publicly available information, it is possible that other investors are also monitoring these filings and investing accordingly. This may result in inflation of the share price of securities in which the Fund invests. 

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is comprised of U.S. listed equity positions reported on Form 13F by a select group of entities characterized as premier activist investors, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider").

Activist investors are selected from a universe of investors that aim to buy securities to put public pressure on management to increase shareholder value, as defined by the Index Provider. The Index Provider applies a number of criteria to further narrow the pool of investors, such as size and performance track record. Activist investors must have minimum reported holdings of $500 million in their Form 13F to be considered for the Underlying Index.

Once the pool of activist investors has been determined, the Index Provider utilizes Form13F filings to compile the top three stock holdings from each of these investors. The stocks are screened for liquidity, equal weighted, and rebalanced quarterly following the Form 13F filing timeline. As of January 1, 2015, the Underlying Index had 50 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Form 13F Data:The Form 13F filings used to select the securities in the Underlying Index are filed up to 45 days after the end of each calendar quarter. Therefore a given investor may have already sold its position by the time the security is added to the Underlying Index. Furthermore, the Form 13F filing may only disclose a subset of a particular investor’s holdings, as not all securities are required to be reported on the Form 13F. As a result, the Form 13F may not provide a complete picture of the holdings of a given investor. An investor may hold long positions for a number of reasons, and the Index Provider has not investigated such reasons or the strategies followed by an investor who makes the filings.  The Underlying Index may not be representative of the investor's universe or the strategies that give rise to the reported holdings. Because the Form 13F filing is publicly available information, it is possible that other investors are also monitoring these filings and investing accordingly. This may result in inflation of the share price of securities in which the Fund invests. 

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts("ADRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is comprised of small capitalization companies reported on Form 13F by hedge funds and other institutional investors, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). Small-capitalization companies are defined as companies whose market capitalization is less than $3 billion as of the date of its inclusion in the Underlying Index. Hedge funds are defined as privately offered pooled investment vehicles.

Using a proprietary methodology developed by the Index Provider, the Index Provider determines the pool of hedge funds and other institutional investors whose Form 13F holdings may be included in the Underlying Index. Hedge funds are selected from a pool of thousands of privately offered pooled investment vehicles based on the size of their reported equity holdings and the efficacy of replicating their publicly disclosed positions. Institutional investors are selected based on the qualitative factor of whether they have a strong management team with a track record of creating shareholder value. Additional filters are applied to exclude the holdings of hedge funds and institutional investors that report less than $500 million in holdings on the Form 13F or that have high turnover rates for equity holdings, as defined by the Index Provider. Turnover is a measure of the hedge funds and other institutional investors' trading activity or holdings that have been "turned over" or replaced with other holdings.

Once the pool of investors has been determined, the Index Provider utilizes Form 13F filings to compile 100 stocks that represent the top small cap positions from these investors. The stocks must meet minimum liquidity thresholds to be included in the Underlying Index. Stocks in the Underlying Index are equal weighted and rebalanced quarterly following the Form 13F filing timeline. As of January 1, 2015, the Underlying Index had 100 constituents ranging in market capitalization from $180 million to $9 billion. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Consumer Discretionary Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Consumer Discretionary Sector.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

This may result in inflation of the share price of securities in which the Fund invests. 

Risks Related to Investing in the Consumer Discretionary Sector: The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

The Fund invests at least 80% of its total assets in the securities of the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is comprised of international companies reported on Form 13F by hedge funds and other institutional investors, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). Hedge funds are defined as privately offered pooled investment vehicles. International companies refer to American Depositary Receipts ("ADRs") and other non-US companies.

Using a proprietary methodology developed by the Index Provider, the Index Provider determines the pool of hedge funds and other institutional investors whose Form 13F holdings may be included in the Underlying Index. Hedge funds are selected from a pool of thousands of privately offered pooled investment vehicles based on the size of their reported equity holdings and the efficacy of replicating their publicly disclosed positions. Institutional investors are selected based on the qualitative factor of whether they have a strong management team with a track record of creating shareholder value. Additional filters are applied to exclude the holdings of hedge funds and institutional investors that report less than $500 million in holdings on their Form 13F or that have high turnover rates for equity holdings, as defined by the Index Provider. Turnover is a measure of the hedge funds and other investors' trading activity or holdings that have been "turned over" or replaced with other holdings.

Once the pool of investors has been determined, the Index Provider utilizes Form 13F filings to compile 50 stocks that represent the top international positions from these investors. The stocks must meet minimum size and liquidity thresholds to be included in the Underlying Index. Stocks in the Underlying Index are equal weighted and rebalanced quarterly following the Form 13F filing timeline. As of January 1, 2015, the Underlying Index had 50 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”).

If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in a sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk:Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Form 13F Data:The Form 13F filings used to select the securities in the Underlying Index are filed up to 45 days after the end of each calendar quarter. Therefore a given investor may have already sold its position by the time the security is added to the Underlying Index. Furthermore, the Form 13F filing may only disclose a subset of a particular investor’s holdings, as not all securities are required to be reported on the Form 13F. As a result, the Form 13F may not provide a complete picture of the holdings of a given investor. An investor may hold long positions for a number of reasons, and the Index Provider has not investigated such reasons or the strategies followed by an investor who makes the filings.  The Underlying Index may not be representative of the investor's universe or the strategies that give rise to the reported holdings. Because the Form 13F filing is publicly available information, it is possible that other investors are also monitoring these filings and investing accordingly. This may result in inflation of the share price of securities in which the Fund invests. 

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund had not yet commenced investment operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index tracks the performance of high income securities globally across a variety of asset classes, including equities, Master Limited Partnerships ("MLPs"), Real Estate Investment Trusts (“REITs”), preferred securities and fixed income securities, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). Fixed income securities include emerging market government bonds and high yield corporate bonds (otherwise known as "junk bonds"). The Underlying Index may include equity securities, fixed income securities and exchange traded funds (“ETFs”).

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund uses a representative sampling strategy with respect to the Underlying Index. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These include country weightings, market capitalization and other financial characteristics of securities. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Credit Risk: The Fund is subject to the risk that debt issuers and other counterparties may not honor their obligations.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if currencies of the underlying securities depreciate against the U.S. dollar.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including Brazil, Colombia, Malaysia, Mexico, the Philippines, Poland, South Africa, South Korea, Thailand and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Because certain securities markets in the emerging countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

High-Yield Securities Risk: Securities that are rated below investment grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-“ by Standard & Poor’s® (a division of the McGraw-Hill Companies, Inc.) (“S&P”) and Fitch, Inc. (“Fitch), “Baa3” by Moody’s® Investors Service, Inc. (“Moody’s”), or “BBBL” by Dominion Bond Rating Service Limited (“Dominion”)), or are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, may be more volatile than higher-rated securities of similar maturity.

Infrastructure Risk: Companies engaged in the building of infrastructure are affected by the risk that economic conditions will not warrant spending on new infrastructure projects. In addition, infrastructure companies are subject to a variety of factors that may adversely affect their business or operations.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices. Certain MLP securities may trade less frequently than those of larger companies due to their smaller capitalizations.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

MLP Risk: Investments in securities of MLPs involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, and cash flow risks. MLP common units and other equity securities can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment towards MLPs or the energy sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms of distributable cash flow). Prices of common units of individual MLPs and other equity securities also can be affected by fundamentals unique to the partnership or company, including earnings power and coverage ratios.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Non-U.S. Issuers Risk: Non-U.S. issuers carry different risks from bonds issued by U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Preferred Stock Risk: Preferred stock is subject to many of the risks associated with debt securities, including interest rate risk. As interest rates rise, the value of the preferred stocks held by the Fund are likely to decline. In addition, preferred stock may not pay a dividend, an issuer may suspend payment of dividends on preferred stock at any time, and in certain situations an issuer may call or redeem its preferred stock or convert it to common stock.

Prepayment Risk: When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.

Risk of High Dividend Yield Stocks: High yielding stocks are often speculative, high risk investments. These companies can be paying out more than they can support and may reduce their dividends or stop paying dividends at any time, which could have a material adverse effect on the stock price of these companies and the Fund’s performance.

Risk of Investing in ETFs:The Fund may hold ETFs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETFs. While the risks of owning shares of an underlying ETF generally reflect the risks of owning the underlying securities of the index the ETF is designed to track, lack of liquidity in an underlying ETF can result in its value being more volatile than the underlying portfolio securities. Because the value of other ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund’s holdings in those shares at the most optimal time, thereby adversely affecting the Fund’s performance. In addition, ETF shares may trade at a premium or discount to net asset value.

In addition, investments in the securities of other ETFs may involve duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs, which could result in greater expenses to the Fund. By investing in another ETF the Fund becomes a shareholder thereof. As a result, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses indirectly paid by shareholders of the other ETF, in addition to the fees and expenses Fund shareholders indirectly bear in connection with the Fund’s own operations.

If the other ETF fails to achieve its investment objective, the value of the Fund’s investment will decline, adversely affecting the Fund’s performance. ETFs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, some ETFs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act.

Risk of Investing in Real Estate Stocks and Real Estate Investment Trusts: The Fund may invest in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the Financials Sector:Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation of any individual financial company or on the sector as a whole cannot be predicted.

Small and Mid-Capitalization Companies Risk: Small and mid-capitalization companies may have greater volatility in price than the stocks of large-capitalization companies due to limited product lines or resources or a dependency upon a particular market niche.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 85.07% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in preferred securities. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index tracks the performance of the highest-yielding preferred securities in the United States and Canada, as determined by Standard & Poor’s Financial Services , LLC, a subsidiary of the McGraw-Hill Companies (“S&P”), the provider of the Underlying Index ("Index Provider"). The Underlying Index is comprised of preferred stocks that meet certain criteria relating to size, liquidity, issuer concentration and rating, maturity and other requirements, as determined by the Index Provider. The Underlying Index does not seek to directly reflect the performance of the companies issuing the preferred stock. As of January 1, 2015, the Underlying Index had 50 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

In general, preferred stock is a class of equity security that pays a specified dividend that must be paid before any dividends can be paid to common stockholders, and which takes precedence over common stock in the event of the company’s liquidation. Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights and have economic characteristics similar to fixed-income securities. Preferred stocks generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate. Additionally, preferred stocks often have a liquidation value that generally equals the original purchase price of the preferred stock at the date of issuance. The Underlying Index may include many different categories of preferred stock, such as floating and fixed rate preferreds, perpetual preferred stock, trust preferred securities, cumulative and non-cumulative preferreds or preferred stocks with a callable or conversion feature.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund uses a representative sampling strategy with respect to the Underlying Index. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These include country weightings, market capitalization and other financial characteristics of securities. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Financials Sector.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Financial Institution Risk: Certain of the securities that comprise the Underlying Index, while traded on U.S. exchanges, may be issued by foreign financial institutions. Therefore, the Fund may be subject to the risks of investing in securities issued by foreign companies, which may not be subject to the same regulations as companies domiciled in the U.S. The health of many foreign financial institutions is often tied closely with the financial stability of the local economy in which they are domiciled, and therefore are subject to additional risks including but not limited to: policy changes, slow economic growth, and high levels of debt.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Preferred Stock Risk: Preferred stock is subject to many of the risks associated with debt securities, including interest rate risk. As interest rates rise, the value of the preferred stocks held by the Fund are likely to decline. In addition, preferred stock may not pay a dividend, an issuer may suspend payment of dividends on preferred stock at any time, and in certain situations an issuer may call or redeem its preferred stock or convert it to common stock.

Risk of High Dividend Yield Stocks: High-yielding stocks are often speculative, high risk investments. These companies can be paying out more than they can support and may reduce their dividends or stop paying dividends at any time, which could have a material adverse effect on the stock price of these companies and the Fund’s performance.

Risks Related to Investing in Canada: The Canadian economy is highly dependent on the demand for and price of natural resources. As a result, the Canadian market is relatively concentrated in issuers involved in the production and distribution of natural resources and any changes in these sectors could have an adverse impact on the Canadian economy.

Risks Related to Investing in the Financials Sector:Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation of any individual financial company or on the sector as a whole cannot be predicted.

Securities Lending Risk:Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund is not able to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Additionally, the Fund will bear any loss on the investment of cash collateral it receives. These events could also trigger adverse tax consequences for the Fund. As securities on loan may not be voted by the Fund, there is a risk that the Fund may not be able to recall the securities in sufficient time to vote on material proxy matters.

Small and Mid-Capitalization Companies Risk: Small and mid-capitalization companies may have greater volatility in price than the stocks of large-capitalization companies due to limited product lines or resources or a dependency upon a particular market niche.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities of Real Estate Investment Trusts (“REITs”). The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index tracks the performance of REITs that rank among the highest yielding REITs globally, as determined by Solactive AG, the provider of the Underlying Index (“Index Provider”). The Index Provider screens the highest yielding REITs to exclude REITs that have historically exhibited the highest volatility, as determined by the Index Provider. As of January 1, 2015, the Underlying Index had 30 constituents, 10 of which are foreign companies. The Fund's investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in the Financials Sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk: Investments in Asian markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. The countries in Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Australasian Economic Risk: The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Financials Sector.

Credit Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if foreign currency depreciates against the U.S. dollar.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including South Africa, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk: The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund invests.

Global Real Estate Risk: Since the Fund concentrates its assets in the global real estate industry, the Fund will be impacted by the performance of the global real estate markets.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Prepayment Risk: When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.

Risk of High Dividend Yield Stocks: High-yielding stocks are often speculative, high risk investments. These companies can be paying out more than they can support and may reduce their dividends or stop paying dividends at any time, which could have a material adverse effect on the stock price of these companies and the Fund’s performance.

Risks Related to Investing in Mortgage Real Estate Investment Trusts: Mortgage real estate investment trusts (“REITs”) are exposed to the risks specific to the real estate market as well as credit risk, interest rate risk, leverage risk and prepayment risk.

Risks Related to Investing in Real Estate Stocks and Real Estate Investment Trusts: The Fund may invest companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the Financials Sector:Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation of any individual financial company or on the sector as a whole cannot be predicted.

Securities Market Risk: Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small and Mid-Capitalization Companies Risk: Small and mid-capitalization companies may have greater volatility in price than the stocks of large-capitalization companies due to limited product lines or resources or a dependency upon a particular market niche.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24.63% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index tracks the performance of four asset class categories that are designed to perform differently across different economic environments, as defined by Solactive AG, the provider of the Underlying Index (“Index Provider”). On each rebalance, the Underlying Index allocates 25% each to four asset class categories, as follows:

Asset Class	Allocation
Stocks:
•        U.S. Large Cap Stocks	9%
•        U.S. Small Cap Stocks	3%
•        International Stocks	3%
•        U.S. Real Estate Stocks	5%
•        U.S. and Foreign Natural Resource Stocks	5%
U.S. Treasury Bonds (Long-Term) (remaining maturity greater than 20 years)	25%
U.S. Treasury Bills and Bonds (Short-Term) (remaining maturity of less than three years)	25%
Gold & Silver:
•        Physical Gold ETFs and ETCs	20%
•        Physical Silver ETFs and ETCs	5%
Total	100%

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index may include U.S. and foreign exchange-traded vehicles, including exchange traded funds (“ETFs”) and exchange traded commodities (“ETCs”). As of January 1, 2015, the Underlying Index had 90 constituents, which included ETFs for U.S. Small Cap Stocks and International Stocks, REITs, and ETCs for Gold and Silver.

The Underlying Index rebalances annually. Between rebalances, actual allocations of the Underlying Index may deviate from each allocation shown above as a result of performance differences among the different asset classes. The Index Provider will also rebalance between scheduled rebalance dates if the Underlying Index weights deviate from the above asset class allocation beyond pre-established maximum thresholds, as defined by the Index Provider.

The Adviser will use a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The Fund uses a representative sampling strategy with respect to the Underlying Index. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in a sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodities Regulatory Risk: Gold and silver are commodities. The Commodity Futures Trading Commission ("CFTC") may repropose regulations that may limit the use of commodity interests by the Fund. Any changes in regulations could affect the Fund’s ability to qualify as a regulated investment company under the Internal Revenue Code, or to pursue its investment program as described in this Prospectus.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: The Fund is expected to invest in securities in emerging market countries, currently including Brazil, Chile, China, Czech Republic, Poland, South Africa, South Korea, Taiwan, and Turkey, a list that might be expanded as the Underlying Index rebalances over time. The Fund’s investment in an emerging market country may be subject to a greater risk of loss than investments in developed markets. Because certain securities markets in the emerging countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Interest Rate Risk:Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Foreign Investment Company Risk: Some Fund holdings may be characterized as “passive foreign investment companies” ("PFICs") for U.S. tax purposes. Because the application of the PFIC rules may affect, among other things, the character of gains and the amount of gain or loss and the timing of the recognition of income with respect to PFIC shares, and may subject the Fund itself to tax on certain income from PFIC shares, the amount that must be distributed to shareholders and will be taxed to shareholders as ordinary income or long-term capital gain may be increased or decreased substantially as compared to a fund that did not invest in PFIC shares.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Commodities: The Fund may invest in commodity ETFs. Exposure to commodities may subject the Fund greater volatility than investments in traditional securities. The value of commodities may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments.

Risks Related to Investing in Large-Capitalization Stocks: Large-capitalization stocks may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better – or worse – than the stock market in general. These periods have, in the past, lasted for as long as several years.

Risks Related to Investing in International Stocks: The Fund’s investments in foreign stocks can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions. In addition, world events – such as political upheaval, financial troubles, or natural disasters – could adversely affect the value of securities issued by companies in foreign countries or regions. Stocks of companies located in emerging markets will be substantially more volatile, and substantially less liquid, than the stocks of companies located in more developed foreign markets.

Risks Related to Investing in Real Estate Stocks and Real Estate Investment Trusts: The Fund may invest in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in Natural Resource Stocks: Any decline in the general level of prices of oil and gas, minerals or agricultural commodities would be expected to have an adverse impact on these stocks. The prices of these stocks are particularly vulnerable to decline in the event of deflationary economic conditions.

Risks Related to Investing in Gold and Silver: The Fund invests in ETFs and/or ETCs that invest in physical gold or silver. Gold and silver generate no interest or dividends, and the return from investments in gold and silver will be derived solely from the price gains or losses from the commodity. Investing in ETFs or ETCs that invest in physical gold or silver may subject the Fund to greater volatility than investments in traditional securities. Gold and silver may also be significantly affected by developments in the gold and silver mining industry, respectively, and prices of gold and silver may fluctuate sharply over short periods of time. Income derived from gold and silver (or ETFs or ETCs investing in gold and silver) is generally not qualifying income for purposes of the regulated investment company diversification tests under the Internal Revenue Code.

Risks Related to Investing in ETFs:The Fund may hold ETFs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETFs. While the risks of owning shares of an underlying ETF generally reflect the risks of owning the underlying securities of the index the ETF is designed to track, lack of liquidity in an underlying ETF can result in its value being more volatile than the underlying portfolio securities. Because the value of other ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund’s holdings in those shares at the most optimal time, thereby adversely affecting the Fund’s performance. In addition, ETF shares may trade at a premium or discount to net asset value.

In addition, investments in the securities of other ETFs may involve duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs, which could result in greater expenses to the Fund. By investing in another ETF the Fund becomes a shareholder thereof. As a result, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses indirectly paid by shareholders of the other ETF, in addition to the fees and expenses Fund shareholders indirectly bear in connection with the Fund’s own operations.

If the other ETF fails to achieve its investment objective, the value of the Fund’s investment will decline, adversely affecting the Fund’s performance. ETFs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, some ETFs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act.

Risks Related to Investing in ETCs: The Fund may hold ETCs to gain exposure to physical gold and silver. As a result, the Fund is subject to the same risks as the underlying ETCs. While the risks of owning shares of an underlying ETC generally reflect the risks of owning the underlying metals the ETC holds, lack of liquidity in an underlying ETC can result in its value being more volatile than the metals themselves. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETCs. ETCs that invest in physical gold or silver may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this prospectus. Additionally, ETCs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act. Income derived from commodities is generally not qualifying income for purposes of the regulated investment company diversification tests under the Internal Revenue Code.

Small- and Mid-Capitalization Companies Risk: Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

U.S. Treasury Obligations Risks: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's or and Underlying Fund's U.S. Treasury obligations to decline.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. Because the Fund had not commenced operations as of the most recent fiscal year end, no portfolio turnover figures are available for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its total assets in securities that comprise the Underlying Index. The Underlying Index is comprised of Chinese Renminbi (“RMB”)-denominated bonds ("RMB Bonds") that are issued or distributed within mainland People’s Republic of China (“China or the “PRC”). The Fund’s 80% investment policy is non-fundamental and may be changed without shareholder approval upon 60 days’ prior written notice to shareholders.

The Underlying Index is designed to provide exposure to RMB-denominated bonds that are issued or distributed within mainland China. The Underlying Index, strictly in accordance with its guidelines and mandated procedures, includes securities with a minimum maturity of one year and with an outstanding principal amount of RMB 1 billion. The Underlying Index is composed of RMB denominated bonds issued by governments, agencies, and Central State-Owned Enterprises (CSOEs). The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Fund will seek to achieve its investment objective by primarily investing directly in Chinese bonds issued or distributed in the PRC. Because the Fund does not satisfy the criteria to qualify as a Renminbi Qualified Foreign Institutional Investor ("RQFII") or Qualified Foreign Institutional Investor ("QFII") itself, the Fund intends to invest directly in RMB-denominated bonds via the RQFII quota of the Fund’s sub-adviser, GF International Investment Management Limited ("GFIIM" or “Sub-Adviser”). The Sub-Adviser has obtained RQFII status and has been granted an RQFII quota of at least 500 Million RMB (“RQFII quota”), which the Sub-Adviser will use all or a portion of to invest the portion of the Fund’s assets allocated to it by the Adviser in RMB-denominated bonds. At such time that the Sub-Adviser has utilized its entire RQFII quota, the Sub-Adviser may, subject to applicable regulations, apply for an increase of the RQFII quota. Assets not allocated to the Sub-Adviser for investment directly in RMB-denominated bonds will be managed by the Adviser.

The Adviser will use a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

Because of the practical difficulties and expense of purchasing all of the securities in the Index, the Fund does not expect to purchase all of the securities in the Index. Instead, the Adviser will utilize a “sampling” methodology in seeking to achieve the Fund’s objective. As such, the Fund may purchase a subset of the bonds in the Index in an effort to hold a portfolio of bonds with generally the same risk and return characteristics of the Index.

The Adviser expects that, over time, the correlation between the Fund's performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund will concentrate its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was concentrated in Chinese bonds in the Financials Sector.

Risk [Heading]

rr_RiskHeading

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors in the Fund should be willing to accept high degree of volatility in the price of the Fund’s shares and the possibility of significant losses.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the economy of China.

Asset Class Risk: Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk: Unlike most other ETFs, the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Chinese Banking Industry Risk: The Chinese banking industry is a highly regulated industry and is subject to laws and regulations touching all aspects of the banking business. The principal regulators include the China Banking Regulatory Commission (“CBRC”) and the People’s Bank of China (“PBOC”). These regulators are given wide discretion in exercising their authority. The banking regulatory regime in China is currently undergoing significant changes, including changes in laws and regulations, as it moves toward a more transparent regulatory process. Some of these changes may have an adverse impact on the performance of Chinese banks that issued RMB Bonds and thus may adversely affect their capacity to honor their commitments under the RMB Bonds to the holders of such bonds, which may include the Fund.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and the financials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector.To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Financials Sector.

Credit Risk: Bonds are subject to credit risk. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt or to otherwise honor its obligations. Bonds are subject to varying degrees of credit risk which may be reflected in credit ratings. There is a possibility that the credit rating of a bond may be downgraded after purchase, which may adversely affect the value of the security.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Foreign Security Risk: RMB bonds are issued by foreign issuers. Investments in the securities of foreign issuers are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security is traded. The Fund may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China.

Index Tracking Risk: The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index and incurs costs associated with buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index and raising cash to meet redemptions or deploying cash in connection with newly created Creation Units (defined herein). Because the Fund bears the costs and risks associated with buying and selling securities while such costs are not factored into the return of the Index, the Fund’s return may deviate significantly from the return of the Index. The Fund may not be fully invested at times either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions or pay expenses. In addition, the Fund’s use of a representative sampling approach may cause the Fund to not be as well correlated with the return of the Index as would be the case if the Fund purchased all of the securities in the Index in the proportions represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Interest Rate Risk: Bonds are also subject to interest rate risk. Interest rate risk refers to fluctuations in the value of a bond resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most bonds go down. When the general level of interest rates goes down, the prices of most bonds go up. The historically low interest rate environment increases the risk associated with rising interest rates. In addition, bonds with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than bonds with shorter durations.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk: The Fund is subject to the risk that the Adviser’s investment management strategy may not produce the intended results.

Market Risk: The prices of the securities in the Fund are subject to the risk associated with investing in bonds, including general economic conditions and sudden and unpredictable drops in value. An investment in the Fund may lose money.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

New Adviser Risk: GFIIM is a newly registered investment adviser and has not previously advised a registered investment company.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Premium/Discount Risk: Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk: China has begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Regulatory Risk: Changes in the law in the United States or China could result in the inability of the Fund to operate as intended and negatively affect the Fund and its shareholders.

Reliance on Trading Partners Risk: The Fund invests in an economy that is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the economy in which the Fund invests. As a result of trading partners risk, the Fund is particularly exposed to U.S. Economic Risk.

Replication Management Risk: An investment in the Fund involves risks similar to those of investing in any bond fund, such as market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in security prices. However, because the Fund is not “actively” managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security’s issuer was in financial trouble. Therefore, the Fund’s performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

Risks Related to Investing in the Financials Sector:Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Risks Related to the RQFII Regime and Investing in RMB Bonds: As of the date of this Prospectus, more than 80% of the Index was comprised of RMB Bonds. The Fund intends to invest directly in RMB Bonds through the Sub-Adviser’s RQFII quota. Because the Fund will not be able to invest directly in RMB Bonds in excess of the Sub-Adviser’s RQFII quota, the size of the Fund’s direct investment in RMB Bonds may be limited. In addition, the RQFII quota of the Sub-Adviser may be reduced or revoked by the Chinese regulators if, among other things, the Sub-Adviser fails to observe State Administration of Foreign Exchange (SAFE) and other applicable Chinese regulations. The Fund cannot predict what would occur if the RQFII quota of the Sub-Adviser or RQFII or QFII quotas generally were reduced or eliminated, although such an occurrence would likely have a material adverse effect on the Fund, including the requirement that the Fund dispose of certain or all of its RMB Bond holdings. Therefore, any such reduction or elimination may have a material adverse effect on the ability of the Fund to achieve its investment objective. If the Fund is unable to obtain sufficient exposure to the performance of RMB Bonds due to the limited availability of the Sub-Adviser’s RQFII quota or other investments, the Fund could, among other things, as a defensive measure limit or suspend creations until the Adviser and/or the Sub-Adviser determine that the requisite exposure to the RMB Bonds is obtainable. During the period that creations are suspended, the Fund could trade at a significant premium or discount to its NAV and could experience substantial redemptions.

RMB Bonds are traded on the inter-bank bond market or the exchange-traded bond market in the PRC. Currently, the interbank bond market is much larger with respect to trading volume and is generally considered more liquid than the exchange-traded bond market. The inter-bank bond market is a quote-driven over-the-counter (“OTC”) market for institutional investors, while the exchange-traded bond market is an electronic automatic matching system where securities are traded on the Shanghai Stock Exchange or the Shenzhen Stock Exchange.  To the extent that the Fund were to invest in securities contained in the Underlying Index via the exchange-traded bond market rather than the inter-bank bond market, the transactions in the underlying bonds could be subject to wider spreads between the bid and the offered prices of the bonds. This wider spread could adversely affect price at which the Fund could purchase or sell the bonds and impair the Fund’s performance.

The RMB Bond market is volatile with a risk of suspension of trading in a particular security or government intervention. Securities on the RMB Bond market, including securities in the Index, may be suspended from trading without an indication of how long the suspension will last, which may impair the liquidity of such securities. The regulations which regulate investments by RQFIIs in the PRC and the repatriation of capital from RQFII investments are relatively new. The application and interpretation of such investment regulations are therefore relatively untested and there is no certainty as to how they will be applied. The PRC authorities and regulators have been given wide discretion in such investment regulations and there is no precedent or certainty as to how such discretion may be exercised now or in the future. The application and interpretation of such investment regulations may adversely affect the Fund. In addition, there are custody risks associated with investing through a RQFII, where due to requirements regarding establishing a custody account in the joint names of the Fund and the Sub-Adviser the Fund’s assets may not be as well protected from the claims of creditors as it may be if the Fund were to have an account in its name only.

Specific rules governing taxes on capital gains derived by RQFIIs and QFIIs from the trading of PRC securities have yet to be announced. In the absence of specific rules, the tax treatment of the Fund’s investments in RMB Bonds through the Sub-Adviser’s RQFII quota should be governed by the general PRC tax provisions and provisions applicable to RQFIIs. Under these provisions, the Fund is generally subject to a tax of 10% on any dividends, distributions and interest it receives from its investment in PRC securities. In addition, a nonresident enterprise is subject to withholding tax at a rate of 10% on its capital gains. However, it is unclear if this tax will be applied to investments by an RQFII such as the Sub-Adviser or what the methodology for calculating or collecting the tax will be. Withholding taxes on dividends, interest and capital gains may be taxed at a reduced rate under an applicable tax treaty, but the application of such treaties for an RQFII acting on behalf of a foreign investor (i.e., the Sub-Adviser acting on behalf of the Fund) is also uncertain. It is also unclear how China’s business tax may apply to activities of an RQFII such as the Sub-Adviser and how such application may be affected by tax treaty provisions. The current PRC tax laws and regulations may be revised or amended in the future, and may be applied retroactively. Any revision or amendment in tax laws and regulations may adversely affect the Fund. In light of this uncertainty, the Fund plans to reserve 10% of its realized and unrealized gains from its RMB Bond investments to meet any potential withholding tax liability. This reserve may turn out to be excessive or inadequate in light of the Fund’s actual tax liabilities. The tax reserve will be reflected in the Fund’s daily NAV calculations as a deduction from the Fund’s NAV. Therefore, if the Fund’s tax reserve turns out to be excessive or inadequate and the Fund’s tax reserve and related deduction from NAV is modified accordingly, this will work to the benefit or detriment, respectively, of the Fund’s existing shareholders at the time the uncertainty surrounding the Fund’s tax liabilities is resolved. The Fund may also be liable to the Sub-Adviser for any tax that is imposed on the Sub-Adviser by the PRC with respect to the Fund’s investments.

The Sub-Adviser, as a licensed RQFII, is currently permitted to repatriate RMB daily and is not subject to RMB repatriation restrictions or prior approval. However, there is no assurance that RQFIIs may not be subject to restrictions or prior approval requirements in the future. Any additional restrictions imposed on the Sub-Adviser or RQFIIs generally may have an adverse effect on the Fund’s ability to invest directly in RMB Bonds and its ability to meet redemption requests. If the Fund’s direct investments in RMB Bonds through the Sub-Adviser’s RQFII quota become subject to repatriation restrictions, the Fund may be unable to satisfy distribution requirements applicable to regulated investment companies (“RICs”) under the Internal Revenue Code of 1986, as amended (the “ Code”), and be subject to income and excise tax at the Fund level. In addition, the Fund could be required to recognize unrealized gains, pay taxes and make distributions before re-qualifying for taxation as a RIC. See the prospectus under “Shareholder Information—Tax Information—Taxes on Distributions” for more information. The Fund may elect, for U.S. federal income tax purposes, to treat Chinese taxes (including withholding taxes) paid by the Fund as paid by its shareholders. Even if the Fund is qualified to make that election and does so, this treatment will not apply with respect to amounts the Fund reserves in anticipation of the imposition of withholding taxes not currently in effect (as discussed above). If these amounts are used to pay any tax liability of the Fund in a later year, they will be treated as paid by the shareholders in such later year, even if they are imposed with respect to income of an earlier year. See the Prospectus under “Shareholder Information—Tax Information” for a further description of this risk.

Risks Related to Investing in China: The Fund will seek to achieve its investment objective by primarily investing directly in Chinese RMB Bonds. Investing in Chinese securities involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, (i) the small size of the market for Chinese securities and the low volume of trading, resulting in lack of liquidity and in price volatility, (ii) currency devaluations and other currency exchange rate fluctuations or blockage, (iii) the nature and extent of intervention by the Chinese government in the Chinese securities markets, whether such intervention will continue and the impact of such intervention or its discontinuation, (iv) the risk of nationalization or expropriation of assets, (v) the risk that the Chinese government may decide not to continue to support economic reform programs, (vi) limitations on the use of brokers, (vii) higher rates of inflation, (viii) greater political, economic and social uncertainty, (ix) market volatility caused by any potential regional or territorial conflicts or natural disasters and (x) the risk of increased trade tariffs, embargoes and other trade limitations.

The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, interest rates, allocation of resources and capital reinvestment, among others. The Chinese central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China.

The Chinese securities markets are emerging markets characterized by relatively low trading volume, resulting in substantially less liquidity and greater price volatility. There is also less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the United States. Accounting, auditing and financial reporting standards in China are different from U.S. standards and, therefore, disclosure of certain material information may not be made. In addition, less information may be available to the Fund and other investors than would be the case if the Fund’s investments were restricted to securities of U.S. issuers. There is also generally less governmental regulation of the securities industry in China, and less enforcement of regulatory provisions relating thereto, than in the United States. Moreover, it may be more difficult to obtain a judgment in a court outside the United States. Mainland China’s legal system is based on statutes enacted by various state bodies dealing with economic matters such as foreign investment, company organization and governance, taxation and trade. These laws are quite recent with published court opinions based on these being limited and non-binding. This makes the interpretation and enforcement of these laws and regulations uncertain. With respect to laws pertaining to bankruptcy proceedings, such laws in mainland China are generally less developed than and different from such laws in the United States. Therefore, bankruptcy proceedings can take more time to resolve than similar proceedings in the United States and results can be unpredictable. These and other factors could have a negative impact on the Fund’s performance and increase the volatility of an investment in the Fund.

The Chinese government strictly regulates the payment of foreign currency denominated obligations and sets monetary policy. In addition, the Chinese economy is export-driven and highly reliant on trade. Adverse changes to the economic conditions of its primary trading partners, such as the United States, Japan and South Korea, would adversely impact the Chinese economy and the Fund’s investments. Moreover, the current major slowdown in other significant economies of the world, such as the United States, the European Union and certain Asian countries, may adversely affect economic growth in China. An economic downturn in China would adversely impact the Fund’s investments.

Emerging markets such as China can experience high rates of inflation, deflation and currency devaluation. The value of RMB may be subject to a high degree of fluctuation due to, among other things, changes in interest rates, the effects of monetary policies issued by the PRC, the United States, foreign governments, central banks or supranational entities, the imposition of currency controls or other national or global political or economic developments. The Fund invests a significant portion of its assets in investments denominated in RMB and the income received by the Fund will principally be in RMB. The Fund’s exposure to RMB and changes in value of RMB versus the U.S. dollar may result in reduced returns for the Fund. Moreover, the Fund may incur costs in connection with conversions between U.S. dollars and RMB. RMB is currently not a freely convertible currency. The Chinese government places strict regulation on RMB and sets the value of RMB to levels dependent on the value of the U.S. dollar, but the Chinese government has been under pressure to manage the currency in a less restrictive fashion so that it is less correlated to the U.S. dollar. The Chinese government’s imposition of restrictions on the repatriation of RMB out of mainland China may limit the depth of the offshore RMB market and reduce the liquidity of the Fund’s investments. There may not be sufficient amounts of RMB for the Fund to be fully invested because the Fund has to convert U.S. dollars received from the purchase of Creation Units (defined herein) into RMB to purchase RMB denominated investments. As a result, these restrictions may adversely affect the Fund and its investments.

Sampling Risk: The Fund’s use of a representative sampling approach will result in its holding a smaller number of securities than are in the Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. Conversely, a positive development relating to an issuer of securities in the Index that is not held by the Fund could cause the Fund to underperform the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Securities Market Risk: Investments in the securities of foreign issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Because many foreign securities markets may be limited in size, the prices of securities that trade in such markets may be influenced by large traders. Certain foreign markets that have historically been considered relatively stable may become volatile in response to changed conditions or new developments. Increased interconnectivity of world economies and financial markets increases the possibility that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions. Foreign issuers are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping than are U.S. issuers, and therefore, not all material information may be available or reliable. Securities exchanges or foreign governments may adopt rules or regulations that may negatively impact the Fund’s ability to invest in foreign securities or may prevent the Fund from repatriating its investments. The Fund may invest in shares of foreign investment companies, including Hong Kong-listed ETFs, the shares of which are listed and traded primarily on a foreign securities exchange. The Fund as an investor in a foreign fund may not be afforded the same investor protections that are provided by the U.S. federal securities laws. The Fund may also invest in depositary receipts, which involve similar risks to those associated with investments in foreign securities. In addition, the Fund may not receive shareholder communications or be permitted to vote the securities that it holds, as the issuers may be under no legal obligation to distribute shareholder communications.

Sovereign Bond Risk: Investments in sovereign bonds involves special risks not present in corporate bonds. The governmental authority that controls the repayment of the bonds may be unable or unwilling to make interest payments and/or repay the principal on its bond or to otherwise honor its obligations. If an issuer of sovereign bonds defaults on payments of principal and/or interest, the Fund may have limited recourse against the issuer. During periods of economic uncertainty, the market prices of bonds, and the Fund’s NAV, may be more volatile than prices of corporate bond, which has resulted in losses to the holders of such debt.

Subordinated Obligations Risk: Payments under some RMB Bonds may be structurally subordinated to all existing and future liabilities and obligations of each of the respective subsidiaries and associated companies of an issuer of a RMB Bond. Claims of creditors of such subsidiaries and associated companies will have priority as to the assets of such subsidiaries and associated companies over the issuer and its creditors, including the Fund, who seek to enforce the RMB Bond. Certain RMB Bonds do not contain any restrictions on the ability of the subsidiaries of the issuers to incur additional unsecured indebtedness.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosures rates may have an adverse impact on the economy of China.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index tracks the total return performance of a portfolio of eleven exchange-traded funds (each, an "ETF") and two exchange-traded products (each an "ETP") (each ETP and ETF a "Constituent" and together the "Constituents"), as defined by J.P. Morgan Security LLC, the provider of the Underlying Index ("Index Provider"). The Constituents eligible for inclusions are noted below. The share prices of the ETFs and ETPs are expected to track the performance of equities or bonds in developed or emerging markets, real estate investments, U.S. Treasury bonds, U.S. Treasury Inflation Protected Securities, a single commodity or a portfolio of commodity futures contracts. The Underlying Index allocates index weights among the Constituents based on a proprietary methodology created by the Index Provider.

On a monthly basis and subject to certain weighting constraints, the Underlying Index is rebalanced to reallocate index weights among the Constituents so that the resulting portfolio would have had the highest return during the previous six months and an annualized volatility level of 10% or less over the same period (subject to upward adjustment under limited circumstances). This methodology is informed by the “modern portfolio theory” approach to asset allocation, which suggests that an investor allocate among assets in a manner that maximizes return for a given risk appetite. Since the index weights assigned to the Constituents at each monthly rebalancing are determined based on past performance, there is no guarantee that any monthly rebalancing will result in the Underlying Index achieving the highest possible returns for the relevant month.The Underlying Index is described in greater detail in the Information Regarding the Underlying Index and the Index Provider section of this Prospectus.

As of January 1, 2015, the Constituents eligible for inclusion in the Underlying Index are: the Vanguard S&P 500 ETF, the iShares

Core S&P Small-Cap ETF, the Vanguard FTSE Developed Markets ETF, the iShares 20+ Year Treasury Bond ETF, the iShares 1-3 Year Treasury Bond ETF, the iShares iBoxx $ Investment Grade Corporate Bond ETF, the SPDR^® Barclays High Yield Bond ETF, the Vanguard FTSE Emerging Markets ETF, the iShares J.P.Morgan USD Emerging Markets Bond ETF, the Vanguard REIT ETF, the iShares TIPS Bond ETF, the iShares S&P GSCI Commodity-Indexed Trust and the iShares Gold Trust.

Set forth below are the weighting constraints applicable to each Constituent and each sector that may be represented in the Underlying Index:

Sector	Fund*	Min Weight	Max Weight
Developed Equity 50% Total Cap	Vanguard S&P 500 ETF	0%	20%
	iShares Core S&P Small-Cap ETF	0%	20%
	Vanguard FTSE Developed Markets ETF	0%	20%

*iShares® is a registered trademark of BlackRock (BlackRock, Inc. and its subsidiaries). Neither BlackRock nor the iShares® Funds make any representations regarding the advisability of investing in Fund.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the Constituents of the Underlying Index and publishes information regarding the level of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund uses a representative sampling strategy with respect to the Underlying Index. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These include country weightings, market capitalization and other financial characteristics of securities. The Fund may or may not hold all of the securities in the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation.

The Fund concentrates its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in a sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asset Class Risk: Constituents of the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodities Regulatory Risk: The Commodity Futures Trading Commission ("CFTC") may repropose regulations that may limit the use of commodity interests by the Fund. Any changes in regulations could affect the Fund’s ability to qualify as a regulated investment company or to pursue its investment program as described in this Prospectus.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Credit Risk: Credit risk is the risk that an issuer of debt securities will be unable to pay principal and interest when due, or that the value of the security will suffer because investors believe the issuer is less able to make required principal and interest payments.

Currency Risk: The Fund, or an ETF in which the Fund invests, may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Market Risk: Investments in emerging market countries may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk: Investments in the securities of foreign issuers are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security is traded. The Fund may lose value due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural disaster could occur in a geographic region in which the Fund or ETF invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

High Yield Securities Risk: Securities that are rated below investment grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-“ by Standard & Poor’s® (a division of the McGraw-Hill Companies, Inc.) (“S&P”) and Fitch, Inc. (“Fitch), “Baa3” by Moody’s® Investors Service, Inc. (“Moody’s”), or “BBBL” by Dominion Bond Rating Service Limited (“Dominion”)), or are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, may be more volatile than higher-rated securities of similar maturity.

Income Risk:Income risk is the risk that the Fund’s income will decline because of falling interest rates.

Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Liquidity Risk: Liquidity risk is the risk that the Fund or an ETF may not be able to sell a security in a timely manner at a desired price.

Management Risk: The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Optimization Risk: The Fund is based on “modern portfolio theory” approach to asset allocation. There is no guarantee that this Underlying Index will outperform any alternative strategy that might be employed in respect of the component assets or that past volatilities and correlations of particular asset classes will be indicative of future results.

Passive Foreign Investment Company Risk: Some Fund holdings may be characterized as “passive foreign investment companies” ("PFICs") for U.S. tax purposes. Because the application of the PFIC rules may affect, among other things, the character of gains and the amount of gain or loss and the timing of the recognition of income with respect to PFIC shares, and may subject the Fund itself to tax on certain income from PFIC shares, the amount that must be distributed to shareholders and will be taxed to shareholders as ordinary income or long-term capital gain may be increased or decreased substantially as compared to a fund that did not invest in PFIC shares.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Realized Volatility Risk: The weights of the component assets are determined such that the hypothetical historical volatility of the rebalanced portfolio would have been no more than 10%. However, the realized volatility of the Fund over any period may be more or less than 10%.

Risks Related to Investing in Commodities: The Fund may invest in commodity ETFs. Exposure to commodities may subject the Fund to greater volatility than investments in traditional securities. The value of commodities may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments.

Risks Related to Investing in ETPs: The Fund may hold ETPs to gain exposure to commodities. As a result, the Fund is subject to the same risks as the underlying ETPs. While the risks of owning shares of an underlying ETP generally reflect the risks of owning the underlying commodities contracts and exposure the ETP holds, lack of liquidity in an underlying ETP can result in its value being more volatile than the metal itself. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETPs. ETPs that invest in commodities contracts and exposure may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this prospectus. Additionally, ETPs are not registered under the Investment Company Act of 1940 ("1940 Act") and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act. Income derived from certain commodities-related investments is generally not qualifying income for purposes of the gross income test to qualify as a “regulated investment company” (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). Although income derived from ETPs that are treated as foreign corporations for U.S. tax purposes is expected to be qualifying income, future legislation or guidance may treat this income as not so qualifying.

Risks Related to Investing in ETFs:The Fund may hold ETFs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETFs. While the risks of owning shares of an underlying ETF generally reflect the risks of owning the underlying securities of the index the ETF is designed to track, lack of liquidity in an underlying ETF can result in its value being more volatile than the underlying portfolio securities. Because the value of other ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund’s holdings in those shares at the most optimal time, thereby adversely affecting the Fund’s performance. In addition, ETF shares may trade at a premium or discount to net asset value.

In addition, investments in the securities of other ETFs may involve duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs, which could result in greater expenses to the Fund. By investing in another ETF the Fund becomes a shareholder thereof. As a result, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses indirectly paid by shareholders of the other ETF, in addition to the fees and expenses Fund shareholders indirectly bear in connection with the Fund’s own operations.

If the other ETF fails to achieve its investment objective, the value of the Fund’s investment will decline, adversely affecting the Fund’s performance. ETFs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, some ETFs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act.

Risks Related to Investing in Gold: The Fund may invest in ETFs and/or ETPs that invest in physical gold. Gold generates no interest or dividends, and the return from investments in gold will be derived solely from the price gains or losses from the commodity. Gold may also be significantly affected by developments in the gold mining industry, and prices of gold may fluctuate sharply over short periods of time. Income derived from gold (or in some cases ETFs or ETPs investing in physical gold) is generally not qualifying income for purposes of the RIC gross income tests under the Code. In August 2011, the Internal Revenue Service (“IRS”) announced that it would stop issuing private letter rulings authorizing favorable tax treatment for funds that invest indirectly in commodities such as gold and silver through offshore subsidiaries or certain derivatives. The IRS has previously issued a number of private letter rulings to funds in this area, concluding that such investments generate “qualifying income” for RIC qualification purposes. It is unclear how long this suspension will last. The IRS has not indicated that any previously issued rulings in this area will be affected by this suspension. This suspension of guidance by the IRS means that the tax treatment of such investments is now subject to some uncertainty.

Risks Related to Investing in Inflation-Linked Bonds: The Fund or ETF may invest in inflation-linked bonds, which are income-generating instruments whose interest and principal payments are adjusted for inflation – a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

Risks Related to Investing in Large-Capitalization Companies: The stock of large-capitalization companies may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better – or worse – than the stock market in general. These periods have, in the past, lasted for as long as several years.

Risks Related to Investing in Real Estate Stocks and REITs:The Fund may invest in an underlying fund that invests in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the United States: The Fund or an ETF may have significant exposure to United States issuers. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund or an ETF has exposure.

Securities Market Risk: Because certain securities markets in the countries in which the Fund or ETF may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk: Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tax Status Risk: The Fund intends to pay dividends each taxable year to enable it to continue to satisfy the distribution requirements necessary to qualify for treatment as a RIC. If the Fund were to distribute to its shareholders less than the minimum amount required for any year, the Fund would become subject to federal income tax for that year on all of its taxable income and recognized gains, even those distributed to its shareholders. In addition, under the Code, the Fund may not earn more than 10% of its annual gross income from gains resulting from the sale of commodities and precious metals. This could make it more difficult for the Fund to pursue its investment strategy and maintain qualification as a RIC.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Turnover Risk: The Fund may experience relatively high portfolio turnover, which may result in increased transaction costs and lower Fund performance.

U.S. Treasury Obligations Risks: U.S. Treasury obligations may differ in their interest rates, maturities times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's or an underlying fund's U.S. Treasury obligations to decline.

Valuation Risk: The sales price the Fund or ETF could receive for a security may differ from the Fund’s or ETF's valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Global X | JPMorgan US Sector Rotator Index ETF (“Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses of the JPMorgan U.S. Sector Rotator TR Series X Index (“Underlying Index”), an index composed of underlying equity exchange-traded funds ("ETFs") and a fixed income ETF.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund and the other ETFs in which the Fund invests (each, an “Underlying Fund” and collectively, the “Underlying Funds”), pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. To the extent an Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund. From the Fund's commencement of operations on October 22, 2014 to October 31, 2014, the Fund's portfolio turnover rate is 63.35% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of the Underlying Funds that themselves seek investment results corresponding to their own underlying indexes. The Fund invests at least 80% of its total assets in the securities of the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index aims to participate in the best-performing U.S. sectors of the market while limiting its exposure to the market during periods of high volatility or market declines, as defined by J.P. Morgan Securities LLC, the provider of the Underlying Index ("Index Provider"). The Underlying Index is based on a proprietary methodology from the Index Provider.

The Underlying Index rebalances monthly to reflect changing market conditions by tracking the performance of a portfolio that may include a U.S. Treasury Bond ETF and zero to five ETFs selected out of a pool of ten U.S. sector ETFs. The sectors represented by the U.S. sector ETFs are: consumer discretionary, consumer staples, energy, financials, healthcare, industrial, utilities, materials, technology and real estate.

On each monthly rebalancing date, the Underlying Index seeks to select up to five U.S. sector ETFs with the highest positive performance during the prior month. The Underlying Index will include an allocation to the U.S. Treasury Bond ETF if fewer than five U.S. sector ETFs have positive performance during the prior month. The U.S. sector ETFs selected for inclusion in the Underlying Index each month are equal-volatility weighted, based on each U.S. sector ETF’s realized volatility during the prior month, meaning that each U.S. sector ETF has the same amount of volatility contribution to the Underlying Index as of such monthly rebalancing date. If the overall realized volatility of the portfolio of selected U.S. sector ETFs exceeds 20%, based on each U.S. sector ETF’s realized volatility during the prior month, the weight assigned on a monthly rebalancing date to each U.S. sector ETF is adjusted down proportionally and the exposure is re-allocated to the U.S. Treasury Bond ETF in order to reduce the overall volatility of the Underlying Index to 20% as of such monthly rebalancing date. Since the index weights assigned to the U.S. Sector ETF and the U.S. Treasury Bond ETF are determined on past performance, there is no guarantee that any monthly rebalancing will result in the Underlying Index achieving the highest possible returns for the relevant month. The Underlying Index is described in greater detail in the "Information Regarding the Underlying Index and the Index Provider" section of this Prospectus.

As of January 1, 2015, the U.S. sector ETFs and U.S. Treasury Bond ETF eligible for consideration as components of the Underlying Index each month are: the Consumer Discretionary Select Sector SPDR® Fund, the Consumer Staples Select Sector SPDR® Fund, the Energy Select Sector SPDR® Fund, the Financial Select Sector SPDR® Fund, the Health Care Select Sector SPDR® Fund, the Industrial Select Sector SPDR® Fund, the Utilities Select Sector SPDR® Fund, the Materials Select Sector SPDR® Fund, the Technology Select Sector SPDR® Fund, the SPDR^® Dow Jones REIT ETF, and the iShares® 1-3 Year Treasury Bond ETF.

Set forth below are the weighting constraints applicable to each U.S. Sector ETF and the U.S. Treasury Bond ETF that may be represented in the Underlying Index (and thus the Fund):

Sector	Fund*	Min Weight	Max Weight
US	Consumer Discretionary Select Sector SPDR Fund	0%	20%
	Financial Select Sector SPDR Fund	0%	20%
	Utilities Select Sector SPDR Fund	0%	20%
	Consumer Staples Select Sector SPDR Fund	0%	20%
	Health Care Select Sector SPDR Fund	0%	20%
	Materials Select Sector SPDR Fund	0%	20%
	Energy Select Sector SPDR Fund	0%	20%
	Industrial Select Sector SPDR Fund	0%	20%
	Technology Select Sector SPDR Fund	0%	20%
	SPDR® Dow Jones REIT ETF	0%	20%
Short Term Treasuries	iShares 1-3 Year Treasury Bond ETF	0%	100%

iShares® is a registered trademark of BlackRock (BlackRock, Inc. and its subsidiaries). Neither BlackRock nor the iShares® Funds make any representations regarding the advisability of investing in the Fund.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and the Global X Management Company, LLC, the investment adviser for the Fund ("Adviser"). The Index Provider determines the relative weightings of the constituents of the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions beyond the mechanics built into the Underlying Index when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to follow the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2014, the Underlying Index was not concentrated in a sector.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

Asset Class Risk: Constituents of the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund and an underlying fund may invest in the materials sector, which is susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on the Fund.

Concentration Risk: To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Income Risk: The Fund's income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, bonds in the Underlying Index are substituted or the Fund otherwise needs to purchase additional bonds.

Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk: The Fund is subject to the risk that the Adviser’s investment management strategy may not produce the intended results.

Market Risk: The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Model Portfolio Risk: The risk that investments selected using a proprietary methodology (i.e., quantitative model) may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the Fund to achieve positive returns or outperform the market.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risk of Investing in the United States: The Fund may have significant exposure to U.S. issuers. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risks Related to Investing in ETFs:The Fund may hold ETFs to gain exposure to certain asset classes. As a result, the Fund may be subject to the same risks as the underlying ETFs. While the risks of owning shares of an underlying ETF generally reflect the risks of owning the underlying securities of the index the ETF is designed to track, lack of liquidity in an underlying ETF can result in its value being more volatile than the underlying portfolio securities. Because the value of other ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund’s holdings in those shares at the most optimal time, thereby adversely affecting the Fund’s performance. In addition, ETF shares may trade at a premium or discount to net asset value.

In addition, investments in the securities of other ETFs may involve duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs, which could result in greater expenses to the Fund. By investing in another ETF the Fund becomes a shareholder thereof. As a result, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses indirectly paid by shareholders of the other ETF, in addition to the fees and expenses Fund shareholders indirectly bear in connection with the Fund’s own operations.

If the other ETF fails to achieve its investment objective, the value of the Fund’s investment will decline, adversely affecting the Fund’s performance. ETFs that invest in commodities may be, or may become, subject to regulatory trading limits that could hurt the value of their securities and could affect the Fund’s ability to pursue its investment program as described in this Prospectus. Additionally, some ETFs are not registered under the 1940 Act and therefore, are not subject to the regulatory scheme and investor protections of the 1940 Act.

Risks Related to Investing in Real Estate Stocks and Real Estate Investment Trusts:The Fund may invest in an underlying fund that invests in companies that invest in real estate, such as REITs, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases risk and could adversely affect a real estate company's operations and market value in periods of rising interest rates.

Risks Related to Investing in the Consumer Discretionary Sector: The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Risks Related to Investing in the Consumer Staples Sector: The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Risks Related to Investing in the Energy Sector: The value of securities issued by companies in the energy sector may decline for many reasons, including, among others, changes in energy prices, government regulations, energy conservation efforts and potential civil liabilities.

Risks Related to Investing in the Financial Sector: Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Risks Related to Investing in the Health Care Sector: The healthcare sector may be affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a patent may adversely affect their profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Risks Related to Investing in the Industrial Sector: The industrials sector may be affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Risks Related to Investing in the Materials Sector: Companies in the materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

Risks Related to Investing in the Technology Sector: Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Risks Related to Investing in the Utilities Sector: The utilities sector is subject to significant government regulation and oversight. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with regulations, among other factors.

Small- and Mid-Capitalization Companies Risk: Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Turnover Risk:The Fund may experience relatively high portfolio turnover, which may result in increased transaction costs and lower Fund performance.

U.S. Treasury Obligations Risks:U.S. Treasury obligations may differ in their interest rates, maturities times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's or an underlying fund's U.S. Treasury obligations to decline.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Central American countries of Belize, Honduras, El Salvador, Costa Rica, Nicaragua, Panama and Guatemala, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Central American securities, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or markets. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Central America.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a Central American currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inCentral America,which could affect the economy or particular business operations of companies economically tied to that region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:Many economies in Latin America have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the regions' exports and many economies in this region, are particularly sensitive to fluctuations in commodity prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Central America: Investment in Central American securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of the drug trade. The governments of certain countries in Central America may exercise substantial influence over many aspects of the private sector and may own or control many companies. Future government actions could have a significant effect on the economic conditions in such countries, which could have a negative impact on private sector companies.

Risks Related to Investing in Frontier Markets: Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Central and Northern Europe. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Central and Northern European countries of Austria, Belgium, Denmark, Finland, France, Germany, Luxemburg, the Netherlands, Norway, Sweden, Switzerland, and the United Kingdom, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 50 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Central and Northern European securities, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or markets. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a Central or Northern European currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inCentral or Northern Europe,which could affect the economy or particular business operations of companies economically tied to that region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Central and Northern Europe. The economies of Central and Northern Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries overall may cause an adverse impact on each nation’s individual economy. Concerns about the rising government debt levels of certain European countries could impact the financial stability of Central and Northern European countries. Some Central and Northern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments.  

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Southern Europe.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a Southern European currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Greece is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inSouthern Europe, which could affect the economy or particular business operations of companies economically tied to Southern Europe.

Government Debt Risk: Portugal, Spain, Italy and Greece currently have high levels of debt and public spending, which may stifle economic growth, contribute to prolonged periods of recession or lower the sovereign debt ratings in these countries and adversely impact investments in the Fund.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Southern Europe: The countries of Southern Europe, including Greece, Spain, Italy and Portugal, are currently experiencing significant volatility due rising government debt levels, ability to service debt, and potential for defaults. Greece has already begun to impose harsh austerity measures to address its debt situation, and it is possible that other countries in Southern Europe will have to implement similar measures to control debt levels. Such austerity measures would likely have an adverse impact on economic growth in the short and medium term.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Eastern Europe. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Eastern European countries of Belarus, Bulgaria, Czech Republic, Hungary, Moldova, Poland, Romania, Slovakia, Ukraine, Latvia, Lithuania and Estonia, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Eastern European securities, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or markets. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional detail on these risks, please see Risks Related to Investing in Eastern Europe.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a Eastern European currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Some Eastern European countries are considered emerging market countries, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro.

Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Risks Related to Investing in Eastern Europe. The economies of Eastern Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

African Economic Risk: Investment in African securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in African securities excluding South Africa, the Fund will be susceptible to loss due to adverse occurrences affecting the countries in this region. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Africa.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if an African currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Countries in which the fund invests are emerging markets, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Risks Related to Investing in Frontier Markets:Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inAfrica, which could affect the economy or particular business operations of companies economically tied to Africa.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Africa: Investing in Africa involves risks not typically associated with investments in securities of issuers in more developed countries which may negatively affect the value of your investment in the Fund. Such heightened risks include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest. In addition, recent political instability and protests in North Africa and the Middle East have caused significant disruptions to many industries. Continued political and social unrest in these areas may negatively affect the value of your investment in the Fund.

Securities Market Risk: Because the securities markets in Africa are small in size, underdeveloped, and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Africa are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in countries of Sub-Saharan Africa, including but not limited to Tanzania, Senegal, Nigeria, Mauritius, Ethiopia, Kenya, Zambia, Cameroon, Botswana and Namibia, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Certain countries in Sub-Saharan Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Sub-Saharan African securities, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or markets. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Sub-Saharan Africa: Investments are concentrated in companies in Sub-Saharan Africa. The economies of certain sub-Saharan African countries have experienced high unemployment, famine, currency volatility, inflation, general economic malaise, and internal and external conflicts that have resulted in significant displacement of local populations. While some countries in the region have experienced greater political stability and economic growth than neighboring states, adverse social and economic conditions in one country may have a significant adverse effect on other countries of this region.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Frontier Markets, which are defined generally as investable markets that have lower market capitalization and less liquidity than more developed emerging markets. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Frontier Markets, currently including but not limited to Qatar, Jordan, Nigeria, Slovenia, Slovakia, Cyprus, Czech Republic, Mauritius, Argentina, Oman, Bangladesh, Kenya, Romania, Sri Lanka and Vietnam, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 50 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”).

A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

African Economic Risk:Investment in African securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asian Economic Risk:Investments in Asian markets involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of your investment in the Fund. The countries in Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in securities of countries classified as Frontier Markets, the Fund will be susceptible to loss due to adverse occurrences affecting these countries or markets. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Frontier Market Risk.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a relevant currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risk: Frontier Market countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund’s Shares to decline.

Geographic Risk:A natural disaster could occur in a country in which the Fund invests, which could affect the economy or particular business operations of companies economically tied to Frontier Markets.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Latin American Economic Risk:Many economies in Latin America have experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates. Any adverse economic event in one country can have a significant effect on other countries of this region. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the regions' exports and many economies in this region, are particularly sensitive to fluctuations in commodity prices.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will not invest directly in the securities of Saudi Arabia, which is a component of the Underlying Index, but will gain exposure to the Saudi Arabia market by investing in swaps, which is limited to a maximum 20% exposure, while the Underlying Index could theoretically exceed that 20% limit between rebalance dates. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in the Pan Arab countries of Bahrain, Egypt, Jordan, Kuwait, Lebanon, Morocco, Oman, Qatar, Saudi Arabia, Tunisia, and the UAE, as defined by Standard & Poor's ("S&P"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 60 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in the Middle Eastern securities, the Fund will be susceptible to loss due to adverse occurrences affecting these countries. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Middle East.

Counterparty Risk: Counterparty risk is the risk that a counterparty to a swap contract or other similar investment instrument may default on its payment obligation to the Fund. Such a default may cause the value of an investment in the Fund to decrease.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a Middle Eastern currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Derivatives Risk: The Fund may gain exposure to different asset classes by investing in different types of derivative instruments, including but not limited to swaps. Derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses for the Fund. In addition, the prices of the derivative instruments and the prices of underlying securities, interest rates or currencies they are designed to reflect may not move together as expected. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with its Underlying Index.

Emerging Market Risk: The Fund's investments in emerging market countries may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risk:Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Geographic Risk: A natural disaster could occur in a country in which the Fund invests, which could affect the economy or particular business operations of companies economically tied to the Middle East.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Middle East Economic Risk: Certain Middle Eastern markets are only in the earliest stages of development and may be considered “Frontier Markets.” Certain economies in the Middle East depend to a significant degree upon exports of primary commodities such as oil. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Countries in the Middle East may be affected by political instability, war or the threat of war, regional instability, terrorist activities and religious, ethnic and/or socioeconomic unrest. Recent unrest and instability in the larger Middle East region has adversely impacted many economies in the region. Recent political instability and protests in North Africa and the Middle East have caused significant disruptions to many industries.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk: The performance of the Fund may diverge from that of the Underlying Index for a number of reasons. For example, the Fund does not invest directly in the securities of Saudi Arabia, which is a component of the Underlying Index, but gains exposure to the Saudi Arabia market by investing in swaps, which is limited to a maximum 20% exposure, while the Underlying Index could theoretically exceed that 20% limit between rebalance dates. As a result, the Fund’s return may deviate from the return of the Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. As of the date of this Prospectus, the Fund had not yet commenced operations. Thus, no portfolio turnover rate is provided for the Fund.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Morocco, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

African Economic Risk:Investment in African securities involves heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Moroccan securities, the Fund will be susceptible to loss due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Morocco.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Moroccan currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Frontier Market Risk:Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Geographic Risk:A natural disaster could occur inMorocco, which could affect the economy or particular business operations of companies economically tied to Morocco.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Morocco: Morocco’s economy is heavily dependent on the services sector and export of commodities. Decreasing demand for the Morocco’s products and services or changes in governmental regulations on trade may have a significantly adverse effect on Morocco’s economy. Although liberalization in the wider economy has brought economic growth, there is no guarantee that this growth will continue or that the government will not increase direct involvement in the economy in the future. Recent political instability and protests in North Africa and the Middle East have caused significant disruptions to many industries in the region. Continued political and social unrest in these areas may negatively affect the value of your investment in the Fund.

Securities Market Risk: Because securities markets in Morocco are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Morocco are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Investments in Asian markets involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of your investment in the Fund. The countries in Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Sri Lankan securities, the Fund will be susceptible to loss due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent.

In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole.

Emerging Market Risk: Sri Lanka is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk: Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded.

The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Risks Related to Investing in Sri Lanka: Investments are concentrated in companies in Sri Lanka. Sri Lanka’s economy is heavily dependent on tourism and the agricultural sector. Sri Lanka faces many economic hurdles including weak political institutions, poor infrastructure, and a history if intense ethnic conflict. Sri Lanka has suffered significantly from ethnic conflict, and from 1983 to 2009 the Sinhalese government was engaged in a sporadic civil war with a separatist military organization known as the Liberation Tigers of Tamil Eelam (LTTE). Although the government is in the process of rebuilding the nation after the conflict, significant ethnic tensions still exist and there is no guarantee that conflict will not break out again in the future.

Securities Market Risk: Because securities markets in Sri Lanka small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Sri Lanka are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Ukraine, as defined by FTSE International Limited ("FTSE"). As of January 1, 2015, the Underlying Index had 20 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Cash Transactions Risk:Unlike most ETFs, the Fund intends to effect all creations and redemptions partially for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Concentration Risk: Because the Fund's investments are concentrated in Ukrainian securities, the Fund will be susceptible to loss due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Ukraine.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Ukrainian currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inUkraine, which could affect the economy or particular business operations of companies economically tied to Ukraine.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Frontier Markets:Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Risks Related to Investing in Ukraine: Investments are concentrated in companies in Ukraine. Ukraine’s economy faces significant issues with regard to underdeveloped infrastructure, transportation shortfalls, corruption and bureaucracy. Future growth will be highly dependent on the success of wide-ranging legal and economic reforms in order to make the Ukrainian economy more competitive and more transparent for investors. Armed conflict with pro-Russian separatists has drastically impacted the Ukrainian economy, political institutions, and weakened its territorial integrity.

Securities Market Risk: Because securities markets in Ukraine are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Ukraine are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inHungary, which could affect the economy or particular business operations of companies economically tied to Hungary.

Government Debt Risk: Hungary currently has high levels of debt and public spending, which may stifle economic growth, contribute to prolonged periods of recession or lower Hungary’s sovereign debt rating and adversely impact investments in the Fund.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Hungary: Investments are concentrated in companies in Hungary. Hungary has suffered significantly from the recent economic recession due to a high dependence on foreign capital to finance its economy and some of the highest public debt levels in Europe. Key structural weaknesses such as a high and persistent unemployment rate are also hindering the growth of the economy, and labor reforms may be needed to resolve issues that exist in the labor market.

Securities Market Risk: Because securities markets in Hungary are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Hungary are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets. Increase volatility in the Hungarian market may result in the increase use of fair value pricing.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Kazakhstan, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asian Economic Risk:Investments in Asian markets involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of your investment in the Fund. The countries in Asia present different economic and political conditions from those in Western markets, and less social, political and economic stability. Political instability could have an adverse effect on economic or social conditions in these economies and may result in outbreaks of civil unrest, terrorist attacks or threats or acts of war in the affected areas, any of which could materially and adversely affect the companies in which the Fund may invest.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Kazakh securities, the Fund will be susceptible to loss due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Kazakhstan.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Kazakh currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inKazakhstan, which could affect the economy or particular business operations of companies economically tied to Kazakhstan.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk: The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Kazakhstan: Investments are concentrated in companies in Kazakhstan. Kazakhstan’s economy is a resource-based economy that is heavily dependent on the export of natural resources. Fluctuations in certain commodity markets or sustained low prices for its exports could have a significant, adverse effect on Kazakhstan’s economy. While Kazakhstan has recently pursued economic reform and liberalization of many areas in the economy, there is no guarantee that the government will not become directly involved in aspects of the economy in the future.

Risks Related to Investing in Frontier Markets:Frontier markets countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging markets countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline.

Risks Related to Investing in the Materials Sector: Investments in securities in the materials sector are subject to changes in commodity prices, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technical progress, labor relations, governmental regulations and environmental damage and product liability claims.

Securities Market Risk: Because securities markets in Kazakhstan are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Kazakhstan are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities on companies that are domiciled in, principally traded in or whose revenues are primarily from Kuwait. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Kuwait, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider").

Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Middle East Economic Risk: Kuwait and other Middle Eastern markets are only in the earliest stages of development and may be considered “Frontier Markets.” Certain economies in the Middle East depend to a significant degree upon exports of primary commodities such as oil. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Countries in the Middle East may be affected by political instability, war or the threat of war, regional instability, terrorist activities and religious, ethnic and/or socioeconomic unrest. Recent unrest and instability in the larger Middle East region has adversely impacted many economies in the region. Recent political instability and protests in the Middle East and North Africa (which has ethnic, religious and economic ties to the Middle East) have caused significant disruptions to many industries.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in Kuwait: Investments are concentrated in companies in Kuwait. Like most Middle Eastern governments, the federal government of Kuwait exercises substantial influence over many aspects of the private sector. While Kuwait has actively developed industries ranging from industrials to financial services, the government and economy is largely dependent on oil revenue as it is a tax-free country. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy of Kuwait. Recent political instability and protests in North Africa and the Middle East have caused significant disruptions to many industries. Continued political and social unrest in these areas may negatively affect the value of your investment in the Fund.

Risks Related to Investing in the Oil Sector: The oil industry is cyclical and highly dependent on the market price of oil. The market value of companies in the oil industry are strongly affected by the levels and volatility of global oil prices, oil supply and demand, capital expenditures on exploration and production, energy conservation efforts, the prices of alternative fuels, exchange rates and technological advances. Companies in this sector are subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget restraints may have a material adverse effect on the stock prices of companies in the industry.

Securities Market Risk: Because securities markets in Kuwait are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Kuwait are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities of companies that are domiciled in, principally traded in or whose revenues are primarily from Luxembourg. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to reflect broad-based equity market performance in Luxembourg, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in Luxembourgian securities, the Fund will be susceptible to loss due to adverse occurrences affecting that country. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in Luxembourg.

Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if Luxembourg's currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk:The economies of Europe are highly dependent on each other, both as key trading partners and as in many cases as fellow members maintaining the euro. Reduction in trading activity among European countries may cause an adverse impact on each nation’s individual economies. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels, ability to service debt, and potential for defaults of several European countries, including Greece, Spain, Ireland, Italy and Portugal. Eastern European markets remain relatively undeveloped and can be particularly sensitive to political and economic developments. As a result, adverse events in other economies in Europe may greatly impact the economies of Eastern Europe. Investments in Eastern European markets involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. An investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur inLuxembourg, which could affect the economy or particular business operations of companies economically tied to Luxembourg.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Financials Sector: Investments in securities in the financials sector are subject to extensive governmental regulation, which may adversely affect the scope of their activities. The financials sector is exposed to certain risks, such as operating with substantial financial leverage, which may impact the value of investments more severely than investments outside the sector. Recently, the deterioration of the credit markets has caused an adverse impact in a broad range of mortgage, asset-backed, auction rate and other markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial services institutions and markets. This situation has created instability in the financial services markets and caused certain financial services companies to incur large losses or even become insolvent or bankrupt.

Risks Related to Investing in Luxembourg: Investments are concentrated in companies in Luxembourg. Luxembourg’s economy is heavily dependent on the financials sector, particularly banking and financial exports. Luxembourg is a small, land-locked country that does not have significant natural resources and relies mostly on imports to satisfy energy demand. Sustained high prices of certain commodities may have a significant, adverse impact on the economy of Luxembourg.

Securities Market Risk: Because securities markets in Luxembourg are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Luxembourg are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Slovakia is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Industrials Sector: Investments in securities in the industrials sector are subject to fluctuations in supply and demand for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrials sector. Companies also may be adversely affected by environmental damage and product liability claims.

Risks Related to Investing in Slovakia: Slovakia’s economy is heavily dependent on the services and industrials sector. Decreasing demand for the Slovakia’s products and services or changes in governmental regulations on trade may have a significantly adverse effect on the Slovakian economy. Slovakia and surrounding regions have a history of ethnic unrest and conflict. If conflict were to renew in the future, it could have a significant adverse impact on the Fund.

Securities Market Risk: Because securities markets in Slovakia are small in size, underdeveloped and are less regulated and less correlated to global economic cycles than those markets located in more developed countries, the securities markets in Slovakia are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Small- and Mid-Capitalization Companies Risk:Small- and mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. In addition, these companies are often subject to less analyst coverage and may be in early and less predictable periods of their corporate existences. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than larger companies.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities that are economically tied to the advanced materials industry. Companies economically tied to the advanced materials industry include those engaged in the production of materials that are produced with scientific technology and represent advances to traditional materials in order to obtain superior performance in the applications for which the material is used. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index tracks the equity performance of the largest and most liquid companies involved in the advanced materials industry, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents, 12 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in companies involved in the advanced materials industry, which are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have a great impact on companies involved in the advanced materials industry.

Concentration Risk: Because the Fund's investments are concentrated in companies involved in the advanced materials industry, the Fund will be susceptible to loss due to adverse occurrences affecting this industry. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Advanced Materials Industry.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Advanced Materials Industry: The Fund will be concentrated in companies in the advanced materials industry. Companies engaged in the production and distribution of advanced materials may be adversely affected by changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations. The production of advanced materials may involve significant technological expenditure and there is no guarantee that products will be commercially viable.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Relationship to Cement Price: The Underlying Index measures the performance of companies that are primarily engaged in the production and distribution of cement and not the performance of cement prices themselves. The securities of companies involved in the cement industry may under- or over-perform cement prices themselves over the short-term or long-term.

Risks Related to Investing in the Cement Industry: The Fund will be concentrated in companies in the cement industry. Companies engaged in the production and distribution of cement may be adversely affected by changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund will invest at least 80% of its total assets in securities that are economically tied to the land industry, which includes the farmland and timberland industry. Companies economically tied to the land industry include those that own farmland and timberland properties. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index tracks the equity performance of the largest and most liquid companies that own farmland and timberland properties, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 25 constituents, 5 of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk: The Fund invests in the farmland and timberland industry, which may be susceptible to fluctuations in certain commodity markets. Any negative changes in agricultural commodity markets could have a great impact on the farmland and timberland industry.

Concentration Risk: Because the Fund's investments are concentrated in companies involved in the farmland and timberland industry, the Fund will be susceptible to loss due to adverse occurrences affecting this industry. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Land Industry.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Land Industry: The Fund will be concentrated in companies in the farmland and timberland sector. Companies in this sector may be adversely affected by changes in government regulation, world events and economic conditions. Companies in this sector may be adversely affected if the value of farmland or timberland declines, and could be negatively impacted by technological developments and labor relations. In addition, companies in this sector could be adversely affected by commodity price volatility, particularly for agricultural commodities.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Companies in this sector may also face higher risk of government involvement as railroads may be considered key components of national security or potential sources of government revenue. In addition, companies in this sector could be adversely affected by commodity price volatility, technological developments and labor relations.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Lose Money [Text]

rr_RiskLoseMoney

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. As of the date of this Prospectus, the Fund had not yet commenced operations. Thus, no portfolio turnover rate is provided for the Fund.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. Moreover, at least 80% of the Fund’s total assets will be invested in securities that are economically tied to toll roads and ports. Companies economically tied to toll roads and ports include those engaged in the operation of toll roads, airports and seaports. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index tracks the equity performance of companies involved in the toll roads and ports industry, which includes toll roads, airports and seaports, as defined by FTSE International Limited ("FTSE"), the provider of the Underlying Index ("Index Provider"). As of January 1, 2015, the Underlying Index had 29 constituents, all of which are foreign companies. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.

SUMMARY OF PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds’ Strategies and Risks section of the Prospectus and in the Statement of Additional Information ("SAI").

ADR/GDR Risk: To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs and GDRs. While the use of ADRs and GDRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs and GDRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Asset Class Risk:Securities in the Underlying Index or the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk: Because the Fund's investments are concentrated in the toll roads and ports industry, the Fund will be susceptible to loss due to adverse occurrences affecting this industry. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Toll Roads & Ports Industry.

Currency Risk:The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if a foreign currency depreciates against the U.S. dollar.

Custody Risk:Less developed markets are more likely to experience problems with the clearing and settling of trades.

Emerging Market Risk: Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk:Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Foreign Security Risk:Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk:A natural disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Investable Universe of Companies Risk:The investable universe of companies in which a Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s underlying portfolio holdings and on Fund performance.

Issuer Risk:Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Management Risk:The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk:The Fund's NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk:The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Non-Correlation Risk:The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversification Risk:The Fund is classified as a “non-diversified” investment company under the 1940 Act. As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Passive Investment Risk:The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Risks Related to Investing in the Toll Roads & Ports Industry: The Fund will be concentrated in companies in the toll roads and ports sector. Companies in this sector may be adversely affected by changes in government regulation, world events and economic conditions. Companies in this sector may also face higher risk of government involvement as roads and ports may be considered key components of national security or potential sources of government revenue. In addition, companies in this sector could be adversely affected by commodity price volatility, technological developments and labor relations.

Securities Market Risk:Because certain securities markets in the countries in which the Fund may invest are small in size, underdeveloped, and are less regulated and correlated to global economic cycles than those markets located in more developed countries, the securities markets in such countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets.

Tracking Error Risk:The performance of the Fund may diverge from that of the Underlying Index.

Trading Halt Risk:An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk:The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.
