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 Fund 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 fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 296% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund’s investment advisor, Day Hagan Asset Management (the “Advisor”), actively manages the Fund’s portfolio using proprietary investment models co-developed with Ned Davis Research (“NDR”). The Fund is considered a “fund of funds” that, under normal market conditions, seeks to achieve its investment objective by principally investing in unaffiliated equity exchange traded funds (“ETFs”) that track the performance of the individual sectors (“Sectors”) of the S&P 500 Index (“Index”). The Fund will attempt to enhance returns relative to the Index by overweighting and underweighting its exposure to the Sectors relative to the Index and may reduce its overall exposure to ETFs as determined by its risk management model.

The Fund utilizes a model to determine its allocation to each Sector. The model combines sector-specific price-based, economic, fundamental and behavioral indicators to form a composite for each Sector. By combining multiple and diverse indicators, which historically have been shown to add value in Sector allocation decisions, the model seeks to objectively assess the weight of the evidence and generate sector allocation recommendations. As of June 30, 2024, the Sectors are real estate, utilities, consumer staples, information technology, health care, financials, energy, consumer discretionary, materials, industrials, and communications services. The Fund’s allocation to a particular Sector may be greater than 25%. Conversely, the Fund’s allocation to a particular Sector may be reduced to 0% if the Sector’s model composite is at low levels.

 

The Fund’s risk management model defines the Fund’s overall equity allocation target. The model reading represents the net percentage of indicators that are bullish. By taking the weight of the evidence of technical, monetary, economic, valuation, and sentiment indicators, the model measures the potential risk level of factors the stock market faces.

 

Under normal market conditions, the Fund intends to invest predominantly in ETFs but will reduce its exposure by as much as 50% of its assets during times that the model deems the market to have a low reward-to-risk ratio from a historical perspective. During these times, the Fund may hold up to 50% of its assets in cash and cash equivalents, including U.S. Treasury securities and money market funds. The Fund will increase its equity investments when the risk model returns to levels indicating that major risks have potentially subsided.

 

The Fund’s portfolio is rebalanced monthly, although the Advisor may engage in intra-month trades if the models show substantial changes. The Fund actively trades its portfolio securities in an attempt to achieve its investment objective; trading activity may also be increased in periods of high market volatility.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary and you could lose money on your investment in the Fund and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests.

 

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Fund’s turnover may be very high and considerably higher than that of other funds.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Basic Materials Sector Risk. Companies operating in the materials sector may be adversely affected by changes in world events, political, environmental 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.

 

Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Communications Services Sector Risk. Companies in the communications services sector may be affected by industry competition, substantial capital requirements, government regulations and obsolescence of communications products and services due to technological advancement. Companies may encounter cash flow strains due to the need to commit substantial capital to developing new products and services using new technology. Technological innovations may make certain current services obsolete.

 

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

Consumer Staples Sector Risk. The consumer staples sector may be affected by the regulation of various product components and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

 

Equity Securities Risk. The net asset value and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

ETF Structure Risks. The Fund, and the ETFs the Fund invests in, are structured as ETFs and as a result are subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

Energy Sector Risk. Companies operating in the energy sector may be adversely affected by changes in worldwide energy prices, exploration and production spending. In addition, changes in government regulation, world events and political and economic conditions can affect these companies. These companies also are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism, war and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments, geopolitical conflict and related economic sanctions and labor relations also could affect companies in this sector.

 

Fund of Funds Risk. The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

 

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

 

Financial Sector Risk. 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. The impact of more stringent capital requirements, recent or future regulation of any individual financial company, or recent or future regulation of the financial sector as a whole cannot be predicted.

 

Healthcare Sector Risk. 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 company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

 

Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.

 

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Large Capitalization Company Risk. The Fund’s investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

 

Management Risk. The Advisor’s reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models is usually constructed based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Real Estate Sector Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

 

Sector Risk. If the Fund focuses its investments within a particular Sector, it is subject to increased risk. Performance will generally depend on the performance of the Sector, which may differ in direction and degree from that of the overall U.S. stock markets. In addition, financial, economic, business and political developments affecting the Sector may have a greater effect on the Fund than they would if the Fund did not focus on that Sector.

 

Underlying Fund Risk. The ETFs and money market funds (“Underlying Funds”) in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks.

 

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government- sponsored instrumentalities or enterprises.

 

Utilities Sector Risk.

 

Companies in the utilities sector are subject to a variety of factors that may adversely affect their business or operations, including high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital in periods of high inflation and unsettled capital markets; governmental regulation of rates the issuer can charge to customers; costs associated with compliance with environmental and other regulations; effects of economic slowdowns and surplus capacity; increased competition; and potential losses resulting from a developing deregulatory environment.

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models is usually constructed based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund’s investment advisor, Day Hagan Asset Management (the “Advisor”), actively manages the Fund’s portfolio using proprietary investment models co-developed with Ned Davis Research (“NDR”). The Fund is considered a “fund of funds” that, under normal market conditions, seeks to achieve its investment objective by principally investing in unaffiliated fixed income exchange traded funds that invest in fixed income categories (“Underlying Funds”). The fixed income categories to which the Fund may seek exposure through the Underlying

Funds are U.S. investment grade corporate bonds, U.S. long-term treasury securities, U.S. mortgage-backed securities, international investment grade bonds, U.S. treasury inflation-protected securities, U.S. high yield bonds, emerging market bonds, and U.S. floating rate notes (each, a “Category”, and, collectively, the “Categories”). The Fund will attempt to enhance returns relative to the Bloomberg US Aggregate Bond Index by overweighting and underweighting its exposure to the Categories and may reduce its overall exposure to certain ETFs as determined by its risk management model.

 

Under normal market conditions, the Fund will invest, indirectly through the Underlying Funds, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities and other instruments that have economic characteristics similar to such securities. The Fund may invest in Underlying Funds without any constraints as to the duration (i.e., the sensitivity of a fixed income security’s price to interest rate changes), maturity and country of domicile (including emerging market countries) of the securities held by the Underlying Funds. Certain of the Underlying Funds may hold, without limit, debt securities of any credit quality including below investment grade debt securities (also known as “junk” bonds) and may invest in debt securities that are in default.

 

The Fund utilizes a model to determine its allocation to each Category. The model combines unique macroeconomic and technical indicators that are designed to (i) evaluate the relative attractiveness of Underlying Funds across Categories; (ii) reallocate assets from Categories with unfavorable characteristics to areas providing the greatest opportunities; and (iii) protect capital by lowering duration and reducing credit risk during weak economic environments. The indicators for each Category focus on risk/reward characteristics of each Category with the goal of investing in the areas that have the highest probability of maximizing total return. By combining multiple and diverse indicators, which historically have been shown to add value in Category allocation decisions, the model seeks to objectively assess the weight of the evidence and generate Category allocation recommendations. The Fund’s allocation to a particular Category may be greater than 25%. Conversely, the Fund’s allocation to a particular Category may be reduced to 0% if the Category’s model composite is at low levels.

 

The Fund also utilizes a risk model to identify potential broader equity market risks that could negatively impact certain fixed income Categories. Should the model generate a sell signal for equities, the Fund may reduce exposure to fixed income Categories that have historically evidenced a positive correlation with equities. Categories that have historically had positive correlations with U.S. equities are U.S. floating rate notes, U.S. investment grade corporate bonds, U.S. high yield bonds, and emerging market bonds. During times when the model is on a sell signal, portions of the Fund’s allocations to these Categories will be allocated to cash and cash equivalents, including short term U.S. Treasury ETFs, U.S. Treasury securities, and money market funds. The Fund will increase its fixed income investments when the model returns to levels indicating that major risks have potentially subsided.

 

The Fund’s portfolio is rebalanced monthly, although the Advisor may engage in intra-month trades if the models show substantial changes. The Fund actively trades its portfolio securities in an attempt to achieve its investment objective; trading activity may also be increased in periods of high market volatility.

 

The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of issuers.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary and you could lose money on your investment in the Fund and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests.

 

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Fund’s turnover may be very high and considerably higher than that of other funds.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Cash and Cash Equivalents Risk. The Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

 

Credit Risk (for Floating Rate Loans). Credit risk is the risk that the issuer of a security and other instrument will not be able to make principal and interest payments when due. The value of the Fund’s shares, and the Fund’s ability to pay dividends, is dependent upon the performance of the assets in its portfolio. Prices of the Fund’s investments can fall if the actual or perceived financial health of the borrowers on, or issuers of, such investments deteriorates, whether because of broad economic or issuer-specific reasons. In severe cases, the borrower or issuer could be late in paying interest or principal, or could fail to pay altogether.

 

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price. Duration should not be confused with maturity. The maturity of a fixed income security is a measure of the amount of time left until the security “matures” or repays its face value. In contrast, duration measures the price sensitivity of a fixed income security to changes in interest rates rather than the amount of time remaining to maturity. Longer duration tends to result in greater volatility and a greater sensitivity to interest rate changes. For example, a five-year duration means that the fixed income security will decrease in value by 5% if interest rates rise 1% and increase in value by 5% if interest rates fall 1%.

 

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets.

 

ETF Structure Risks. The Fund, and the ETFs the Fund invests in, are structured as ETFs and as a result are subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the NYSE Arca, Inc. (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.
In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

Extension Risk. When interest rates rise, anticipated prepayments may occur at a slower-than expected rate, thus effectively extending the maturity of mortgage-backed securities. Prices of longer-term securities generally fluctuate more widely in response to changes in interest rates than prices of shorter-term securities.

 

Fund of Funds Risk. The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

 

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

 

Fixed Income Securities Risk. The value of fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Floating Rate Loans Risk. A Fund may invest in floating rate loans that are senior in the capital structure of the borrower or issuer, and that are secured with specific collateral. Loans that are senior and secured generally involve less risk than unsecured or subordinated debt and equity instruments of the same borrower because the payment of principal and interest on senior loans is an obligation of the borrower that, in most instances, takes precedence over the payment of dividends or the return of capital to the borrower’s shareholders, and payments to bond holders; and because of the collateral supporting the repayment of the debt instrument. However, the value of the collateral may not equal a Fund’s investment when the debt instrument is acquired or may decline below the principal amount of the debt instrument subsequent to the Fund’s investment. Also, to the extent that collateral consists of stocks of the borrower, or its subsidiaries or affiliates, a Fund bears the risk that the stocks may decline in value, be relatively illiquid, or may lose all or substantially all of their value, causing the Fund’s investment to be under-collateralized. Therefore, the liquidation of the collateral underlying a floating rate loan in which a Fund has invested, may not satisfy the borrower’s obligation to the Fund in the event of non-payment of scheduled interest or principal, and the collateral may not be able to be readily liquidated.

 

In the event of the bankruptcy of a borrower or issuer, a Fund could experience delays and limitations on its ability to realize the benefits of the collateral securing the Fund’s investment. Among the risks involved in a bankruptcy are assertions that the pledge of collateral to secure a loan constitutes a fraudulent conveyance or preferential transfer that would have the effect of nullifying or subordinating a Fund’s rights to the collateral.

 

Floating rate loans are also subject to interest rate risk arising from changes in short-term market interest rates. If short-term market interest rates fall, the yield on a Fund’s shares will also fall. Conversely, when short-term market interest rates rise, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in a Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. The impact of market interest rate changes on a Fund’s yield will also be affected by whether, and the extent to which, the floating rate debt in the Fund’s portfolio is subject to floors on the base rate on which interest is calculated for such loans. So long as the base rate for a loan remains under the floor, changes in short-term interest rates will not affect the yield on such loans. In addition, to the extent that the interest rate spreads on floating rate debt in a Fund’s portfolio experience a general decline, the yield on the Fund’s shares will fall and the value of the Fund’s assets may decrease, which will cause the Fund’s net asset value to decrease.

 

The floating rate debt in which a Fund invests may be generally rated lower than investment-grade credit quality, i.e., rated lower than “Baa3” by Moody’s Investors Service, Inc. (“Moody’s”) or “BBB-” by S&P Global Ratings (“S&P”), or have been made to borrowers who have issued debt securities that are rated lower than investment- grade in quality or, if unrated, would be rated lower than investment-grade credit quality. Investment decisions for a Fund will be based largely on the credit analysis performed by the Advisor, and not entirely on rating agency evaluation. This analysis may be difficult to perform. Information about a loan and its borrower generally is not in the public domain. Many borrowers have not issued securities to the public and are not subject to reporting requirements under federal securities laws. Generally, however, borrowers are required to provide financial information to lenders and information may be available from other loan market participants or agents that originate or administer loans. Certain bank loans may not be considered “securities,” and purchasers, such as a Fund, therefore may not be entitled to rely on the protections of federal securities laws, including antifraud provisions.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Income Risk. The Fund’s distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds, or when the Fund realizes a loss upon the sale of a debt security.

 

Inflation Protected Securities Risk. Inflation-protected debt securities tend to react to changes in real interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation.

 

Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Fixed income securities with longer maturities tend to be more sensitive to interest rates than fixed income securities with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

 

Management Risk. The Advisor’s reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

Mortgage-Backed Securities Risk. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which mortgage loans are guaranteed by the U.S. government, its agencies or instrumentalities. These guarantees are made at the “loan level” and relate only to the payment of principal and interest on the underlying mortgage loans. These loan level governmental guarantees do not cover the payment of principal and interest on, or fluctuations in the market values of, the related mortgage-backed securities, and do not apply to investors’ purchase of shares of the Fund.

 

Mortgage-backed securities issued or guaranteed by governmental agencies or instrumentalities such as Ginnie Mae, or government-sponsored entities such as Fannie Mae and Freddie Mac, are generally known as “agency mortgage-backed securities.” Agency mortgage-backed securities are backed by mortgage loans that satisfy the underwriting and other criteria published by the applicable governmental entity. The payment of interest and principal on these mortgage-backed securities is generally guaranteed by the applicable governmental entity.

 

Mortgage-backed securities issued by private issuers are also known as “non-agency” mortgage-backed securities. Non-agency mortgage-backed securities are not subject to the same stringent underwriting requirements as agency mortgage-backed securities and, therefore, the mortgage loans underlying privately issued mortgage-backed securities may have less favorable collateral, credit risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The market for non-agency mortgage-backed securities is smaller and less liquid than the market for agency mortgage-backed securities.

 

Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary as interest rates rise or fall. An increased rate of prepayments on the Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. The prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise. The liquidity of mortgage-backed securities may change over time.

 

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models are usually constructed based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the 1940 Act. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

 

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

 

Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

 

Underlying Fund Risk. The ETFs and money market funds (“Underlying Funds”) in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks.

 

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government- sponsored instrumentalities or enterprises.

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Fund’s turnover may be very high and considerably higher than that of other funds.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Cash And Cash Equivalents Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Cash and Cash Equivalents Risk. The Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

Trading Issues. Trading in Shares on the NYSE Arca, Inc. (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.
In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Fund of Funds Risk. The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Changing Fixed Income Market Conditions Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Credit Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Credit Risk For Floating Rate Loans [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Credit Risk (for Floating Rate Loans). Credit risk is the risk that the issuer of a security and other instrument will not be able to make principal and interest payments when due. The value of the Fund’s shares, and the Fund’s ability to pay dividends, is dependent upon the performance of the assets in its portfolio. Prices of the Fund’s investments can fall if the actual or perceived financial health of the borrowers on, or issuers of, such investments deteriorates, whether because of broad economic or issuer-specific reasons. In severe cases, the borrower or issuer could be late in paying interest or principal, or could fail to pay altogether.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Duration Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price. Duration should not be confused with maturity. The maturity of a fixed income security is a measure of the amount of time left until the security “matures” or repays its face value. In contrast, duration measures the price sensitivity of a fixed income security to changes in interest rates rather than the amount of time remaining to maturity. Longer duration tends to result in greater volatility and a greater sensitivity to interest rate changes. For example, a five-year duration means that the fixed income security will decrease in value by 5% if interest rates rise 1% and increase in value by 5% if interest rates fall 1%.

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Emerging Markets Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets.

Risk [Text Block] rr_RiskTextBlock

ETF Structure Risks. The Fund, and the ETFs the Fund invests in, are structured as ETFs and as a result are subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the NYSE Arca, Inc. (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

Extension Risk. When interest rates rise, anticipated prepayments may occur at a slower-than expected rate, thus effectively extending the maturity of mortgage-backed securities. Prices of longer-term securities generally fluctuate more widely in response to changes in interest rates than prices of shorter-term securities.

 

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Fixed Income Securities Risk. The value of fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Floating Rate Loans Risk. A Fund may invest in floating rate loans that are senior in the capital structure of the borrower or issuer, and that are secured with specific collateral. Loans that are senior and secured generally involve less risk than unsecured or subordinated debt and equity instruments of the same borrower because the payment of principal and interest on senior loans is an obligation of the borrower that, in most instances, takes precedence over the payment of dividends or the return of capital to the borrower’s shareholders, and payments to bond holders; and because of the collateral supporting the repayment of the debt instrument. However, the value of the collateral may not equal a Fund’s investment when the debt instrument is acquired or may decline below the principal amount of the debt instrument subsequent to the Fund’s investment. Also, to the extent that collateral consists of stocks of the borrower, or its subsidiaries or affiliates, a Fund bears the risk that the stocks may decline in value, be relatively illiquid, or may lose all or substantially all of their value, causing the Fund’s investment to be under-collateralized. Therefore, the liquidation of the collateral underlying a floating rate loan in which a Fund has invested, may not satisfy the borrower’s obligation to the Fund in the event of non-payment of scheduled interest or principal, and the collateral may not be able to be readily liquidated.

 

In the event of the bankruptcy of a borrower or issuer, a Fund could experience delays and limitations on its ability to realize the benefits of the collateral securing the Fund’s investment. Among the risks involved in a bankruptcy are assertions that the pledge of collateral to secure a loan constitutes a fraudulent conveyance or preferential transfer that would have the effect of nullifying or subordinating a Fund’s rights to the collateral.

 

Floating rate loans are also subject to interest rate risk arising from changes in short-term market interest rates. If short-term market interest rates fall, the yield on a Fund’s shares will also fall. Conversely, when short-term market interest rates rise, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in a Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. The impact of market interest rate changes on a Fund’s yield will also be affected by whether, and the extent to which, the floating rate debt in the Fund’s portfolio is subject to floors on the base rate on which interest is calculated for such loans. So long as the base rate for a loan remains under the floor, changes in short-term interest rates will not affect the yield on such loans. In addition, to the extent that the interest rate spreads on floating rate debt in a Fund’s portfolio experience a general decline, the yield on the Fund’s shares will fall and the value of the Fund’s assets may decrease, which will cause the Fund’s net asset value to decrease.

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

Risk [Text Block] rr_RiskTextBlock

Inflation Protected Securities Risk. Inflation-protected debt securities tend to react to changes in real interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation.

Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Fixed income securities with longer maturities tend to be more sensitive to interest rates than fixed income securities with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Day Hagan/Ned Davis Research Smart Sector Fixed Income ETF | Mortgage Backed Securities Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Mortgage-Backed Securities Risk. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which mortgage loans are guaranteed by the U.S. government, its agencies or instrumentalities. These guarantees are made at the “loan level” and relate only to the payment of principal and interest on the underlying mortgage loans. These loan level governmental guarantees do not cover the payment of principal and interest on, or fluctuations in the market values of, the related mortgage-backed securities, and do not apply to investors’ purchase of shares of the Fund.

 

Mortgage-backed securities issued or guaranteed by governmental agencies or instrumentalities such as Ginnie Mae, or government-sponsored entities such as Fannie Mae and Freddie Mac, are generally known as “agency mortgage-backed securities.” Agency mortgage-backed securities are backed by mortgage loans that satisfy the underwriting and other criteria published by the applicable governmental entity. The payment of interest and principal on these mortgage-backed securities is generally guaranteed by the applicable governmental entity.

 

Mortgage-backed securities issued by private issuers are also known as “non-agency” mortgage-backed securities. Non-agency mortgage-backed securities are not subject to the same stringent underwriting requirements as agency mortgage-backed securities and, therefore, the mortgage loans underlying privately issued mortgage-backed securities may have less favorable collateral, credit risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The market for non-agency mortgage-backed securities is smaller and less liquid than the market for agency mortgage-backed securities.

 

Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary as interest rates rise or fall. An increased rate of prepayments on the Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. The prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise. The liquidity of mortgage-backed securities may change over time.

Risk [Text Block] rr_RiskTextBlock

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the 1940 Act. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund’s investment advisor, Day Hagan Asset Management (the “Advisor”), actively manages the Fund’s portfolio using proprietary investment models co-developed with Ned Davis Research (“NDR”). The Fund is considered a “fund of funds” that, under normal market conditions, seeks to achieve its investment objective by principally investing in unaffiliated international equity exchange traded funds (“ETFs”). The Fund will attempt to exceed returns of the MSCI ACWI ex USA Index (the “Index”) by overweighting and underweighting its exposure to geographic locations relative to the Index and may also invest in geographic regions not represented in the Index. The Fund may reduce its overall exposure to ETFs from time to time as determined by its risk management model, as discussed further below. The Index is a free float-adjusted market capitalization weighted index designed to measure the combined equity market performance of developed and emerging markets countries, excluding the U.S. As of May 31, 2023, the Index consisted of securities of 13 developed countries (excluding the US) and 6 emerging markets countries.

Under normal market conditions, the Fund will invest (indirectly through ETFs) primarily in companies located in multiple countries outside the United States. The Fund utilizes region-specific models and rankings to determine its target allocation to each country and regional location. The models and rankings combine region- specific indicators to form a composite for each location. The models and rankings are designed to evaluate fundamental, technical, economic, and behavioral indicators for each region, such as a region’s GDP growth, inflation levels, money supply, equity valuations, price-to-earnings multiples, analyst’s earnings expectations, market trends, and overall investor sentiment. The indicators for each region focus on risk/reward characteristics of each region with the goal of investing in the regions that have the highest probability of maximizing total return. By combining multiple and diverse indicators, the composite models seek to objectively assess the weight of the evidence and generate geographic allocation recommendations. The Fund’s allocation to a particular geographic location may at times be greater than 25%. Conversely, the Fund’s allocation to a particular geographic location may be reduced to 0% if the region’s model composite is at low levels.

 

The Fund will invest in ETFs that invest primarily in specific geographical locations. Accordingly, the Fund will deem the relevant holdings of such ETFs to be tied to the specific geographical locations in which the ETFs invest. The criteria for determining if an ETF’s investments are tied to a particular country or region may differ across ETF providers. Additional information on such criteria can be found in the underlying ETF’s registration statement. A list of the underlying ETFs and their weightings at the end of the most recently completed fiscal year will be included in the Fund’s annual report.

 

The Fund’s risk management model defines the Fund’s overall target equity allocation. The model reading represents the net percentage of indicators that are bullish; that is, the model evaluates the indicators to seek to identify regions with the highest probability of rising equity markets, while also measuring the potential risk level of factors the equity markets face.

 

Under normal market conditions, the Fund intends to invest predominantly in international equity ETFs but will reduce its exposure by as much as 50% of its assets during times that the model deems the international equity markets to have a low reward-to-risk ratio from a historical perspective. During these times, the Fund may hold up to 50% of its assets in cash and cash equivalents, including U.S. Treasury securities and money market funds, or utilize derivative securities designed to effectively reduce, or hedge, the Fund’s overall equity exposure. The Fund may purchase index put options and sell index futures contracts to reduce the overall equity exposure of the Fund and are not intended to achieve a net short position. The decision to purchase or sell derivative securities will be based on the cost and market liquidity of the derivative being used to reduce exposure. The Fund will increase its equity investments when the investment models return to levels indicating that major risks have potentially subsided.

 

The Fund’s portfolio is rebalanced monthly, although the Advisor may engage in intra-month trades if the models show substantial changes. The Fund may actively trades its portfolio securities in an attempt to achieve its investment objective; trading activity may also be increased in periods of high market volatility.

 

The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of issuers.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests.

 

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Fund’s turnover may be very high and considerably higher than that of other funds.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Greater China Investment Risk. Investments in companies located or operating in Greater China (normally considered to be the geographical area that includes mainland China, Hong Kong, Macau and Taiwan) involve risks and considerations not typically associated with investments in the U.S. and other Western nations, such as greater government control over the economy; political, legal and regulatory uncertainty; nationalization, expropriation, or confiscation of property; difficulty in obtaining information necessary for investigations into and/or litigation against Chinese companies, as well as in obtaining and/or enforcing judgments; limited legal remedies for shareholders; alteration or discontinuation of economic reforms; military conflicts, either internal or with other countries; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of Greater China.

 

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

 

Futures Risk. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. In addition, futures contracts may become mispriced or improperly valued relative to the Advisor’s expectations and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference asset because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends.

 

Hedging Risk. Hedging is a strategy in which the Fund uses options or futures to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective.

 

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility, options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

 

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless.
   
  Additionally, purchased options may decline in value due to changes in the price of the underlying reference instrument, passage of time and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, and tracking risk.

 

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing, and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social, and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid, and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

 

Equity Securities Risk. The net asset value and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

ETF Structure Risks. The Fund, and the ETFs the Fund invests in, are structured as ETFs and as a result are subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which may result in a significantly diminished trading market for the Fund’s shares and can lead to differences between the market value of Fund shares and the Fund’s net asset value, and wider bid-ask spreads.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value. Because bid-ask spreads vary over time based on trading volume and market liquidity (including for the underlying securities held by the Fund), spreads may widen if the Fund’s shares have little trading volume and market liquidity. Conversely, the bid-ask spreads will generally be narrower if the Fund’s shares have more trading volume and market liquidity.

 

Fund of Funds Risk. The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory, or other events or conditions affecting countries within the specific geographic regions in which the Fund invests. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value or market price may be more volatile than a more geographically diversified fund.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Management Risk. The Advisor’s reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections, or malfunctions. Because the use of models is usually constructed based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions. The accuracy, timeliness, and sufficiency of information used to construct the models used to manage the Fund’s portfolio, particularly information relating to non-U.S. and emerging markets issuers, are susceptible to risks associated with foreign and emerging markets investments, as described under “Foreign Investment Risk” and “Emerging Market Risk” above.

 

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the 1940 Act. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

 

Underlying Fund Risk. The ETFs and money market funds (“Underlying Funds”) in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks.

 

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government- sponsored instrumentalities or enterprises.

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Fund’s turnover may be very high and considerably higher than that of other funds.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Cash And Cash Equivalents Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Equity Securities Risk [Member]

Equity Securities Risk. The net asset value and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

Risk [Text Block] rr_RiskTextBlock

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Trading Issues [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which may result in a significantly diminished trading market for the Fund’s shares and can lead to differences between the market value of Fund shares and the Fund’s net asset value, and wider bid-ask spreads.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value. Because bid-ask spreads vary over time based on trading volume and market liquidity (including for the underlying securities held by the Fund), spreads may widen if the Fund’s shares have little trading volume and market liquidity. Conversely, the bid-ask spreads will generally be narrower if the Fund’s shares have more trading volume and market liquidity.

Fund of Funds Risk. The Fund, as a shareholder of the underlying funds, indirectly bears its proportionate share of any investment management fees and other expenses of the underlying funds. Further due to the fees and expenses paid by the Fund, as well as small variations in the Fund’s actual allocations to the underlying funds and any cash held in the Fund’s portfolio, the performance and income distributions of the Fund will not be the same as the performance and income distributions of the underlying funds allocated according to the target allocations described here.

Management Risk. The Advisor’s reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Model And Data Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections, or malfunctions. Because the use of models is usually constructed based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions. The accuracy, timeliness, and sufficiency of information used to construct the models used to manage the Fund’s portfolio, particularly information relating to non-U.S. and emerging markets issuers, are susceptible to risks associated with foreign and emerging markets investments, as described under “Foreign Investment Risk” and “Emerging Market Risk” above.

Risk [Text Block] rr_RiskTextBlock

ETF Structure Risks. The Fund, and the ETFs the Fund invests in, are structured as ETFs and as a result are subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Greater China Investment Risk. Investments in companies located or operating in Greater China (normally considered to be the geographical area that includes mainland China, Hong Kong, Macau and Taiwan) involve risks and considerations not typically associated with investments in the U.S. and other Western nations, such as greater government control over the economy; political, legal and regulatory uncertainty; nationalization, expropriation, or confiscation of property; difficulty in obtaining information necessary for investigations into and/or litigation against Chinese companies, as well as in obtaining and/or enforcing judgments; limited legal remedies for shareholders; alteration or discontinuation of economic reforms; military conflicts, either internal or with other countries; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of Greater China.

 

Day Hagan/Ned Davis Research Smart Sector International ETF | Derivatives Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

Futures Risk. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. In addition, futures contracts may become mispriced or improperly valued relative to the Advisor’s expectations and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference asset because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends.

 

Hedging Risk. Hedging is a strategy in which the Fund uses options or futures to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective.

 

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility, options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

 

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless.
   
  Additionally, purchased options may decline in value due to changes in the price of the underlying reference instrument, passage of time and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, and tracking risk.

Risk [Text Block] rr_RiskTextBlock

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing, and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social, and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid, and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory, or other events or conditions affecting countries within the specific geographic regions in which the Fund invests. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value or market price may be more volatile than a more geographically diversified fund.

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 Fund 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. For the fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to track the performance of the Index. The Index is designed to provide broad exposure to the U.S. dollar-denominated investment grade corporate bond sector while at the same time mitigating or “hedging” against U.S. dollar currency risk through the implementation of a gold inflation hedge. The Index provides investment exposure to gold that approximately equals the investment exposure to the corporate bonds comprising the Index and, in doing so, attempts to provide investment exposure to U.S. dollar-denominated corporate bond investments as if such bonds were denominated in gold. The Fund cannot invest in the Index but attempts to track the performance of the Index by investing in the underlying constituents that comprise the Index Components and by investing in securities that seek to maximize correlation with the Index Components as described below.

The Fund’s investment strategy is premised on the proposition that an investment in gold can potentially provide a hedge against inflation for a bond investment. Historically, the price of gold has generally risen when inflation was eroding the value of the U.S. dollar’s purchasing power. Notwithstanding the foregoing, there is no guarantee that the price of gold will move as expected relative to the U.S. dollar, nor is there any guarantee that gold will act as an effective inflation hedge. It is possible that the prices of gold and investment grade corporate bonds may decline at the same time, resulting in a significant decline in the value of the Index.

 

About the Index

 

The Index seeks to provide 100% exposure to the U.S. dollar-denominated investment grade corporate bond sector (the “Bond Component”) plus a gold inflation hedge with a notional value designed to correspond to the value of the Bond Component, with such notional value reset on a monthly basis (the “Gold Hedge Component”). The Index is rebalanced on the last business day of each month. The Index is intended to have higher returns than an unhedged investment in an equivalent portfolio of corporate bonds in environments where declines in the U.S. dollar correspond to a rise in the price of gold. Conversely, the Index is expected to have lower returns than an unhedged investment in an equivalent portfolio of corporate bonds in environments where increases in the U.S. dollar correspond to a decrease in the price of gold.

 

The Index, Bond Index, and Gold Hedge Index are owned, calculated, administered and published by Solactive AG (the “Index Provider”). The Index Provider is not affiliated with the Fund or the Advisor.

 

Bond Component: The Bond Component is represented by the Solactive USD Investment Grade Corporate Index (the “Bond Index”). The Bond Index aims to mirror the performance of investment grade corporate bonds issued in U.S. dollars. The Bond Index is composed of U.S. dollar-denominated, domestic and foreign (including emerging market) corporate debt securities. Corporate debt securities that the Bond Index may hold include “Rule 144A” securities, which are subject to resale restrictions. All constituents of the Bond Index at the time of rebalance must have at least $400 million outstanding, a remaining time to maturity of at least 18 months, and be rated no lower than investment grade (at least BBB- / Baa3) by both Standard & Poor’s and Moody’s. While the Bond Index does not focus on particular economic sectors, industries or group of industries, it may from time to time concentrate its holdings in certain sectors or industries. As of the date of this Prospectus, the Bond Index had significant exposure (over 25% of total assets) to the financials sector and was not concentrated in any one industry.

 

The Bond Index constituents are weighted according to their respective market values in proportion to the aggregated market value of all constituents in the Bond Index Component. As of the date of this Prospectus, the Bond Index Component is composed of approximately 1600 constituent companies. The Index is rebalanced on the last business day of each month.

 

Gold Hedge Component: The Gold Hedge Component is represented by the Solactive Gold Front Month MD Rolling Futures Index ER (the “Gold Hedge Index”). The Gold Hedge Index tracks the performance of the near month gold futures contracts listed on the Chicago Mercantile Exchange. The near month gold future is the futures contract that is closest to expiration. As the futures contracts approach their expiration dates, they are replaced by similar contracts that have a later expiration. This process is referred to as “rolling.”

Fund Replication of the Index

 

The Fund uses a representative sampling strategy and total return swaps to replicate the performance of the Bond Index. Under normal conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) directly, or indirectly through total return swaps, in bonds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The Fund may or may not hold all of the securities that comprise the Bond Index and may not track the Bond Index with the same degree of accuracy as would an investment vehicle replicating the entire Bond Index. The Fund may invest in securities that are not included in the Bond Index when Rational Advisors, Inc., the Fund’s investment advisor (the “Advisor”) believes investing in such securities would help the Fund track the Bond Index. The bond portion of the Fund’s portfolio is expected to have, in the aggregate, investment characteristics (such as market capitalization and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to the securities that comprise the Bond Index. The Advisor primarily focuses on duration, yield, sector, and liquidity to determine investments. In addition to direct investments in bonds, the Fund will invest in total return swap contracts that seek to track the performance of the Bond Index in order to achieve a cumulative 100% notional exposure to the Bond Index.

 

The Fund seeks to gain exposure to the Gold Hedge Index by investing in total return swaps on one or more underlying pools that invest directly or indirectly in gold and/or in futures contracts on gold. Such investments will be made indirectly through the Fund’s Subsidiary (as described below). To the extent that the Fund invests in gold futures, the contracts used will be the same as the contracts in the Gold Hedge Index. The Fund’s investments in rolling futures contracts may be subject to additional costs related to contract rolling. Further dated futures contracts may have higher prices than nearer months due to factors including, but not limited to, seasonality, storage costs, and insurance costs. If the market for further-dated contracts is higher than in the nearer months, the Fund will incur a cost to roll the futures contract as the sale of the near-term contract would be at a lower price than the longer-term contract. The difference in the price of the near and distant contracts determines the extent to which the Fund will incur additional costs related to rolling its contracts.

 

The Subsidiary will also hold cash and cash equivalents such as treasury securities as collateral for the Fund’s futures contract and total return swap investments.

 

It is expected that approximately 80%-90% of the Fund’s assets will be invested in the Bond Component and approximately 10% - 20% will be invested in the Gold Hedge Component (including cash and cash equivalents held as collateral). Futures contracts and total return swaps do not require up-front payments equal to the economic exposure represented by such instruments, which enables the Fund to obtain approximately 100% exposure to the Bond Component, with a corresponding 100% exposure to the Gold Hedge Component. There is no guarantee that the price of gold will move as expected relative to the U.S. dollar, nor is there any guarantee that gold will act as an effective inflation hedge. The Fund’s investment in gold futures contracts could cause the Fund to underperform an unhedged investment grade corporate bond index strategy. The Fund’s 100% exposure to each Component could lead to significant losses if the prices of gold and investment grade corporate bonds decline at the same time.

 

The Fund will concentrate its investments in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries. The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of issuers.

 

Investments in Subsidiary – The Advisor executes a portion of the Fund’s strategy by investing up to 25% of the Fund’s total assets in a wholly owned and controlled subsidiary (the “Subsidiary”). The Subsidiary invests the majority of its assets in gold futures contracts and total return swaps. The Subsidiary is subject to the same investment restrictions as the Fund, when viewed on a consolidated basis. The Subsidiary is SSGBI Fund Limited, a Cayman Islands company. The Subsidiary is advised by the Advisor.

 

Distribution Policy: In order to allow shareholders of the Fund to realize a predictable, but not assured, level of cash flow, the Fund has adopted a policy (which may be modified at any time by its Board of Trustees) to pay monthly distributions on Fund shares at a specific target rate to be determined at the discretion of management. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital. Shareholders should not assume that the source of a distribution from the Fund is net profit. For more information about the Fund’s distribution policy, please turn to “Additional Information About the Fund’s Principal Investment Strategies and Related Risks – Principal Investment Strategies –Distribution Policy and Goals” section in the Fund’s Prospectus.

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Commodity Risk. Investing in the commodities markets (directly or indirectly) may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

 

Commodity Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level, and all distributions from earnings and profits, including any distribution of net tax-exempt income and net long-term capital gains, would be taxable to Fund shareholders as ordinary income. Should the Internal Revenue Service issue further guidance, or Congress enact legislation, that adversely affects the tax treatment of the Subsidiary (which guidance might be applied to the Fund retroactively), it could, among other consequences, limit the Fund’s ability to pursue its investment strategy.

 

Concentration Risk. Because the Fund may concentrate its investments in a sector, industry or group of industries, the Fund may be more vulnerable to adverse market, economic, regulatory, political or other developments affecting such sector, industry or group of industries than a fund that invests its assets more broadly.

 

Counterparty Risk. The Fund may engage in transactions in securities and financial instruments that involve counterparties. Counterparty risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

 

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

 

Derivatives Risk The performance of a derivative instrument depends largely on the performance of an underlying instrument, such as a currency, security, rate or index. In addition, the use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may be unwilling or unable to fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Additionally, the Fund’s obligation to make payments of margin, collateral, or settlement payments to counterparties may heighten liquidity demands on the Fund’s portfolio. Derivatives may be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivatives are subject to the risk of adverse market movements and the risk that markets could experience a change in volatility that adversely impacts Fund returns and the Fund’s obligations and exposures. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, and inflation and deflation. Derivatives are also subject to operational risk, including potential documentation issues, settlement issues, systems failures, inadequate controls, and human error, as well as legal risks arising from insufficient documentation, insufficient capacity or authority of counterparty, or the legality or enforceability of a contract. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

 

Futures Risk. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. In addition, futures contracts may become mispriced or improperly valued relative to the Advisor’s expectations and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference asset because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends.

 

Total Return Swap Risk. Total return swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to replace. Total return over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The Fund’s use of swaps involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and exposes the Fund to the risks associated with derivative instruments described above. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Certain derivatives risks are heightened with respect to over-the-counter (“OTC”) derivative instruments like certain swap agreements and may be greater during volatile market conditions. Such risks include the risk of leverage (i.e., the risk that an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset), counterparty risk (i.e., the risk of a counterparty’s unwillingness or inability to perform its obligations, including as a result of bankruptcy), credit risk, and pricing risk (i.e., swaps may be difficult to value).

 

Distribution Policy Risk. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

 

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price.

 

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

 

ETF Structure Risk. The Fund is structured as an ETF and, as a result, is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Cboe BZX Exchange, Inc (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

 

Financials Sector Focus. Companies operating in the financials sector are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition.

 

Fixed Income Risk. The value of the Fund’s investments in fixed income securities, whether held directly or through futures contracts, will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter- term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Gold Risk. The price of gold may be affected by several factors, including the global gold supply and demand and investors’ expectations with respect to the rate of inflation. Developments affecting the value of gold may have a significant impact on the Fund. Gold markets have been and will likely continue to be subject to sharp price fluctuations, which may lead to significant price fluctuations in the shares of the Fund. In addition, it is possible that a shareholder may not realize his or her investment because the gold markets have historically experienced extended periods of flat or declining prices, in addition to sharp fluctuations. There is no assurance that gold will maintain its long-term value in terms of purchasing power in the future.

 

Hedging Risk. Hedging is a strategy in which the Fund uses a derivative to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective. There is no guarantee that the price of gold will move as expected relative to the U.S. dollar, nor is there any guarantee that gold will act as an effective inflation hedge. The Fund’s gold hedge is expected to cause the Fund to be more volatile than a non-hedged portfolio of bonds. The Fund’s 100% exposures to each of the Bond Component and the Gold Hedge Component could lead to significant losses if the prices of gold and investment grade corporate bonds decline at the same time.

 

Income Risk. The Fund’s distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences deterioration of the underlying debt securities it holds, or when the Fund realizes a loss upon the sale of a debt security.

 

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

 

Index-Related Risk. There is no assurance that the Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Index is designed to achieve, the Index Provider does not guarantee the quality, accuracy or completeness of data in respect of its indices, and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

 

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

 

Management Risk. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

Non-Diversification Risk. To the extent that the Fund holds securities of a smaller number of issuers or invests a larger percentage of its assets in a single issuer than a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers and to economic, political, market or regulatory events affecting any one of those issuers

 

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

 

Regulatory Risk. Changes in the laws or regulations of the United States, Cayman Islands, or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective and could increase the operating expenses of the Fund. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, and the Advisor is a “commodity pool operator” registered with and regulated by the CFTC.

 

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act of 1933 (the “Securities Act”). Rule 144A securities are restricted securities that are not publicly traded and may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets that are typically less active than the market for publicly traded securities. As a result, Rule 144A securities may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund.

 

Sampling Risk. The sampling approach could result in the Fund holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

 

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index or the need to meet various regulatory requirements. In particular, certain regulatory or contractual requirements applicable to the Fund’s use of derivatives could prevent the Fund from being able to effectively apply its representative strategy, which could result in increased index tracking error because the Index is not subject to the same regulatory or contractual requirements. These risks may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

 

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may not be backed by the full faith and credit of the U.S. government which could affect the Fund’s ability to recover should they default.

 

Wholly Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns.

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Strategy Shares Gold-Hedged Bond ETF | Cash And Cash Equivalents Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

 

Strategy Shares Gold-Hedged Bond ETF | E T F Structure Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

ETF Structure Risk. The Fund is structured as an ETF and, as a result, is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Cboe BZX Exchange, Inc (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may not be backed by the full faith and credit of the U.S. government which could affect the Fund’s ability to recover should they default.

 

Strategy Shares Gold-Hedged Bond ETF | Changing Fixed Income Market Conditions Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Strategy Shares Gold-Hedged Bond ETF | Credit Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

 

Strategy Shares Gold-Hedged Bond ETF | Duration Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price.

 

Strategy Shares Gold-Hedged Bond ETF | Emerging Markets Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

 

Strategy Shares Gold-Hedged Bond ETF | Foreign Investment Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

Income Risk. The Fund’s distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences deterioration of the underlying debt securities it holds, or when the Fund realizes a loss upon the sale of a debt security.

 

Strategy Shares Gold-Hedged Bond ETF | Interest Rate Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

 

Strategy Shares Gold-Hedged Bond ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Non-Diversification Risk. To the extent that the Fund holds securities of a smaller number of issuers or invests a larger percentage of its assets in a single issuer than a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers and to economic, political, market or regulatory events affecting any one of those issuers

 

Strategy Shares Gold-Hedged Bond ETF | Derivatives Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Derivatives Risk The performance of a derivative instrument depends largely on the performance of an underlying instrument, such as a currency, security, rate or index. In addition, the use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may be unwilling or unable to fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Additionally, the Fund’s obligation to make payments of margin, collateral, or settlement payments to counterparties may heighten liquidity demands on the Fund’s portfolio. Derivatives may be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivatives are subject to the risk of adverse market movements and the risk that markets could experience a change in volatility that adversely impacts Fund returns and the Fund’s obligations and exposures. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, and inflation and deflation. Derivatives are also subject to operational risk, including potential documentation issues, settlement issues, systems failures, inadequate controls, and human error, as well as legal risks arising from insufficient documentation, insufficient capacity or authority of counterparty, or the legality or enforceability of a contract. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

 

Futures Risk. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. In addition, futures contracts may become mispriced or improperly valued relative to the Advisor’s expectations and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference asset because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends.

 

Total Return Swap Risk. Total return swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to replace. Total return over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The Fund’s use of swaps involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and exposes the Fund to the risks associated with derivative instruments described above. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Certain derivatives risks are heightened with respect to over-the-counter (“OTC”) derivative instruments like certain swap agreements and may be greater during volatile market conditions. Such risks include the risk of leverage (i.e., the risk that an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset), counterparty risk (i.e., the risk of a counterparty’s unwillingness or inability to perform its obligations, including as a result of bankruptcy), credit risk, and pricing risk (i.e., swaps may be difficult to value).

Hedging Risk. Hedging is a strategy in which the Fund uses a derivative to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective. There is no guarantee that the price of gold will move as expected relative to the U.S. dollar, nor is there any guarantee that gold will act as an effective inflation hedge. The Fund’s gold hedge is expected to cause the Fund to be more volatile than a non-hedged portfolio of bonds. The Fund’s 100% exposures to each of the Bond Component and the Gold Hedge Component could lead to significant losses if the prices of gold and investment grade corporate bonds decline at the same time.

Commodity Risk. Investing in the commodities markets (directly or indirectly) may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

 

Strategy Shares Gold-Hedged Bond ETF | Commodity Tax Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Commodity Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level, and all distributions from earnings and profits, including any distribution of net tax-exempt income and net long-term capital gains, would be taxable to Fund shareholders as ordinary income. Should the Internal Revenue Service issue further guidance, or Congress enact legislation, that adversely affects the tax treatment of the Subsidiary (which guidance might be applied to the Fund retroactively), it could, among other consequences, limit the Fund’s ability to pursue its investment strategy.

Distribution Policy Risk. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

Risk [Text Block] rr_RiskTextBlock

Fixed Income Risk. The value of the Fund’s investments in fixed income securities, whether held directly or through futures contracts, will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter- term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Gold Risk. The price of gold may be affected by several factors, including the global gold supply and demand and investors’ expectations with respect to the rate of inflation. Developments affecting the value of gold may have a significant impact on the Fund. Gold markets have been and will likely continue to be subject to sharp price fluctuations, which may lead to significant price fluctuations in the shares of the Fund. In addition, it is possible that a shareholder may not realize his or her investment because the gold markets have historically experienced extended periods of flat or declining prices, in addition to sharp fluctuations. There is no assurance that gold will maintain its long-term value in terms of purchasing power in the future.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

Index-Related Risk. There is no assurance that the Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Index is designed to achieve, the Index Provider does not guarantee the quality, accuracy or completeness of data in respect of its indices, and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

Regulatory Risk. Changes in the laws or regulations of the United States, Cayman Islands, or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective and could increase the operating expenses of the Fund. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, and the Advisor is a “commodity pool operator” registered with and regulated by the CFTC.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act of 1933 (the “Securities Act”). Rule 144A securities are restricted securities that are not publicly traded and may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets that are typically less active than the market for publicly traded securities. As a result, Rule 144A securities may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The sampling approach could result in the Fund holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Risk [Text Block] rr_RiskTextBlock

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index or the need to meet various regulatory requirements. In particular, certain regulatory or contractual requirements applicable to the Fund’s use of derivatives could prevent the Fund from being able to effectively apply its representative strategy, which could result in increased index tracking error because the Index is not subject to the same regulatory or contractual requirements. These risks may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

Wholly Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy:
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund will invest at least 80% of its assets in securities of the Nasdaq 7HANDL™ Index (the “Index”). The Index generally consists of securities issued by exchange-traded funds (“ETFs”) and is split into two components, with a 50% allocation to fixed income and equity ETFs (the “Core Portfolio”) and a 50% allocation to ETFs of 12 asset categories (the “Explore Portfolio”) as described below. Because the Index is comprised of securities issued by other investment companies, the Fund operates as a “fund of funds.”

 

The Index is broadly diversified and seeks to offer the potential for high monthly distributions while maintaining a stable net asset value over time. The Index is expected to include 19 ETFs. The goal of the Index is to represent an allocation to a balanced portfolio of U.S. equities, fixed income securities and alternative investments, then employ leverage in an amount equal to 23% of the total portfolio (measured as a percent of the combined base of the portfolio plus the leverage amount (i.e., 30%/(100%+30%)=23%)). Accordingly, returns for the Index are calculated assuming leverage on the underlying portfolio in the amount of 23% (net of the estimated cost of employing such leverage). To achieve leveraged returns, the Fund will purchase a total return swap on a securities-only version of the Index known as the Nasdaq HANDL™ Base Index (the “Base Index”), which is composed of only ETFs and does not include a leverage component. The Index will have risk characteristics similar to the broad US capital markets and will generally rise and fall with prevailing market conditions, with the goal, but not the guarantee, of achieving a total return sufficient, over time and after expenses, to support a seven percent (7.0%) annual distribution rate.

The Core Portfolio component of the Index seeks to provide broad exposure to the U.S. fixed-income and equity markets and consists of a 70% allocation to U.S. aggregate fixed-income ETFs (the “Core Fixed Income Sleeve”) and a 30% allocation to U.S. large capitalization equity ETFs (the “Core Equity Sleeve”). The Index defines U.S. aggregate fixed income ETFs as those ETFs that provide exposure to the entire U.S. investment grade bond market without limitation of duration or issuer. The Index defines U.S. large cap equity ETFs as those ETFs that provide exposure to a similar market capitalization range of the large capitalization segment of the Nasdaq US Benchmark Index.

 

The Core Fixed Income Sleeve weighting methodology allocates on an equal weight basis to the three U.S. aggregate bond ETFs with the lowest expense ratios after waivers. Half of the Core Equity Sleeve is allocated on an equal weight basis to the three U.S. large cap ETFs with the lowest expense ratios after waivers, and the remaining half of the Core Equity Sleeve is allocated to the largest ETF (by assets under management) that tracks the Nasdaq-100 Index®. The Core Portfolio is rebalanced monthly to weight the Core Portfolio in accordance with the Index’s methodology and is reconstituted annually in January.

 

The Explore Portfolio component of the Index employs a 100% rules-based proprietary momentum-tilted, optimized allocation methodology to provide exposure to non-levered ETFs across a range of U.S. asset categories that have historically provided high levels of income. The following 12 asset categories are represented in the Explore Portfolio, and the Fund expects that less than 16% of the Fund’s assets will be invested in any one category: Dividend Equity – an ETF that provides exposure to domestic dividend-paying stocks; Options Overlay – an ETF that provides exposure to equity portfolios that include an options overlay; High-Yield Bonds – an ETF that provides exposure to domestic high-yield corporate bonds (also known as “junk bonds”) of any duration or maturity; Investment Grade Bonds – an ETF that provides exposure to domestic investment grade corporate bonds of any duration or maturity; MLPs – an ETF that provides exposure to master limited partnerships; MBS – an ETF that provides exposure to mortgage-backed securities (“MBS”), including residential, commercial, agency, and non-agency MBS, high-yield MBS, collateralized debt obligations, and collateralized loan obligations; Active Fixed Income – an ETF that provides broad exposure to actively managed fixed income ETFs that invest in securities of any duration or maturity; Preferred Securities – an ETF that provides exposure to domestic preferred securities; REITs – an ETF that provides exposure to domestic real estate investment trusts; Growth & Income – an ETF that provides exposure to multiple asset portfolios of stocks and bonds or ETFs of stocks and bonds; Utilities – an ETF that provides exposure to domestic utility securities; and Build America Bonds – an ETF that provides exposure to Build America Bonds. Build America Bonds are taxable municipal bonds that include tax credits and/or federal subsidies for bondholders and state and local bond issuers. These bonds may be of any maturity or duration. The Explore Portfolio includes ETFs that can invest without limit as to maturity or duration. Up to 9% of the Index may be exposed to below investment grade securities (i.e., junk bonds) that are rated C or lower through its High Yield Bonds asset category. The Index’s overall indirect exposure to defaulted securities will be less than 5% of the Index.

 

Each asset category in the Explore Portfolio is represented by a single ETF. By default, the ETF representative of an asset category is the largest ETF (by assets under management) in the asset category. However, an ETF that is not the largest ETF in the asset category may serve as the ETF representative if it has an expense ratio after waivers at least 20% lower than the largest ETF in the asset category. If there are multiple such ETFs with expense ratios at least 20% lower than that of the largest ETF, the ETF with the lowest expense ratio after waivers shall serve as the ETF representative of the asset category. An ETF cannot represent more than one asset category.

The 12 ETF representatives of the Explore Portfolio asset categories are weighted using the Index’s proprietary weighting methodology that measures an ETF’s returns, dividend and volatility, subject to the constraints that no position may be less than 15% nor more than 185% of an equal weight position within the Explore Portfolio of the Index. The Explore Portfolio is rebalanced on a monthly basis to weight the Explore Portfolio in accordance with this methodology and is reconstituted annually in January.

 

The Fund employs a “passive management” investment strategy in seeking to achieve its investment objective. The Fund will typically invest 90% of its assets in the Index’s component securities and hold 10% of its assets in cash and cash equivalents, including money market mutual funds and treasury securities, to serve as collateral for the Fund’s 40% total return swap (measured as a percent of the Fund’s portfolio) on the Base Index. The Fund does not include the swap for purposes of the 80% investment test described above. Unlike many investment companies, the Fund does not try to “beat” the Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally will use a replication methodology, meaning it will seek to invest in all of the ETFs comprising the Index in proportion to the weightings in the Index. However, under various circumstances, the Fund may use a representative sampling strategy, whereby the Fund would invest in what it believes to be a representative sample of the component securities of the Index. To the extent the Fund uses a representative sampling strategy, it may not track the Index with the same degree of accuracy as would an investment vehicle replicating the entire Index. The Fund will concentrate its investments in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries. As of the date of this prospectus, the Index is not concentrated.

 

The Index and Base Index were created by and are provided by Bryant Avenue Ventures LLC (the “Index Provider”) and are calculated by Nasdaq, Inc. (the “Index Calculator”). The Index Provider and Index Calculator are not affiliated with the Fund or the Advisor.

 

Distribution Policy: In order to allow shareholders of the Fund to realize a predictable, but not assured, level of cash flow, the Fund has adopted a policy (which may be modified at any time by its Board of Trustees) to pay monthly distributions on Fund shares at a target rate that represents an annualized payout of approximately 7.0% on the Fund’s per-share net asset value on the date of a distribution’s declaration. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital. Shareholders should not assume that the source of a distribution from the Fund is net profit. For more information about the Fund’s distribution policy, please turn to “Additional Information About the Fund’s Principal Investment Strategies and Related Risks – Principal Investment Strategies –Distribution Policy and Goals” section in the Fund’s Prospectus.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests. For purposes of the discussion below, “Fund” means the Fund and/or one or more of the ETFs in which the Fund invests.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with Foreside Fund Services, LLC, the Fund’s distributor (the “Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Build America Bonds Risk. Build America Bonds involve similar risks as municipal bonds, including credit and market risk. In particular, should a Build America Bond’s issuer fail to continue to meet the applicable requirements imposed on such bonds, it is possible that such issuer may not receive federal cash subsidy payments, impairing the issuer’s ability to make scheduled interest payments. The Build America Bond program expired on December 31, 2010, and no further issuance is permitted unless Congress were to renew the program at a future date. As a result, the number of available Build America Bonds is limited, which may negatively affect the value of the Build America Bonds. In addition, there can be no assurance that Build America Bonds will be actively traded. It is difficult to predict the extent to which a market for such bonds will continue, meaning that Build America Bonds may experience greater illiquidity than other municipal obligations. The Build America Bonds outstanding as of December 31, 2010, will continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program will be eligible for the federal tax subsidy.

 

Cash Transactions Risk. ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions partly or entirely in cash, rather than in-kind, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, could be imposed on the Fund and thus decrease the Fund’s NAV to the extent they are not offset by the creation and redemption transaction fees paid by purchasers and redeemers of Creation Units.

 

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Concentration Risk. The Fund will concentrate its investments in securities of a particular industry to the extent the Index does. Economic, legislative or regulatory developments may occur that significantly affect the industry. This may cause the Fund’s net asset value or market price to fluctuate more than that of a fund that does not concentrate in a particular industry.

 

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. Credit risk may be substantial for the Fund.

 

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

 

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option’s strike price. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

 

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk, and sub-strategy risk.

 

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the fund to effectively implement its investment strategy, achieve its objectives and could potentially lead to significant losses.

 

Swaps Risk. Total return swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to replace. Total return over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The Fund’s use of swaps involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and exposes the Fund to the risks associated with derivative instruments described above. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

Written Call Option Risk. Selling covered call or stock index options will limit the Fund’s gain, if any, on its underlying securities. Losses on stock index options may only be partially offset by gains in the Fund’s portfolio if the portfolio does not track the call-related stock index. The Fund continues to bear the risk of a decline in the value of its underlying stocks. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account.

 

Distribution Policy Risk. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

 

Dividend Yield Risk. While the Fund may hold securities of companies that have historically paid a dividend, those companies may reduce or discontinue their dividends, thus reducing the yield of the Fund. Lower priced securities in the Fund may be more susceptible to these risks. Past dividend payments are not a guarantee of future dividend payments.

 

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price. For example, a five-year duration means that the fixed income security will decrease in value by 5% if interest rates rise 1% and increase in value by 5% if interest rates fall 1%.

 

Early Close/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 prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.

 

Equity Securities Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. Equity securities may experience sudden, unpredictable drops in value or long periods of decline in value.

 

ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be halted under certain circumstances. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than the Fund that invests directly in individual securities.

 

ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

Fixed Income Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default). Lowered credit ratings may cause a drop in a fixed income security’s price and are associated with greater risk of default on interest and principal payments. Certain fixed income securities may be paid off early when the issuer can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income. If interest rates rise, repayments of principal on certain fixed income securities may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result, which reduces the Fund’s ability to reinvest at higher rates. These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

 

Index-Related Risk. There is no assurance that the Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Index is designed to achieve, the Index Provider does not guarantee the quality, accuracy or completeness of data in respect of its indices, and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

 

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

 

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

 

Junk Bond Risk. Lower-quality bonds, known as “high-yield” or “junk” bonds, are considered to be speculative with respect to the issuer’s ability to pay interest and principal when due and present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell the bonds in its portfolio. The lack of a liquid market for these bonds could decrease the value of the Fund’s portfolio and net asset value per share.

 

Large Capitalization Company Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

Leverage Risk. The use of leverage can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of funds that do not use such techniques.

 

Management Risk. As the Fund may not fully replicate the Index, it is subject to the risk that investment management strategy may not produce the intended results.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels and political events may adversely affect the securities markets.

 

MLP and MLP-Related Securities Risk. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised) and risks related to the general partner’s limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Depending on the state of interest rates in general, the use of MLPs or MLP-related securities could enhance or harm the overall performance of the Fund.

 

MLP Tax Risk. MLPs do not pay U.S. federal income tax at the partnership level, subject to the application of certain partnership audit rules. Instead, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction of the value of your investment in the Fund and lower income, as compared to an MLP that is not taxed as a corporation.

 

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Index carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models is usually constructed based on data supplied by third parties, the success of the Index’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Mortgage-Backed Securities Risk. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which mortgage loans are guaranteed by the U.S. government, its agencies or instrumentalities. These guarantees are made at the “loan level” and relate only to the payment of principal and interest on the underlying mortgage loans. These loan-level governmental guarantees do not cover the payment of principal and interest on, or fluctuations in the market values of, the related mortgage-backed securities, and do not apply to investors’ purchase of shares of the Fund.

 

Mortgage-backed securities issued or guaranteed by governmental agencies or instrumentalities such as Ginnie Mae, or government-sponsored entities such as Fannie Mae and Freddie Mac, are generally known as “agency mortgage-backed securities.” Agency mortgage-backed securities are backed by mortgage loans that satisfy the underwriting and other criteria published by the applicable governmental entity. The payment of interest and principal on these mortgage-backed securities is generally guaranteed by the applicable governmental entity.

 

Mortgage-backed securities issued by private issuers are also known as “non-agency” mortgage-backed securities. Non-agency mortgage-backed securities are not subject to the same stringent underwriting requirements as agency mortgage-backed securities and, therefore, the mortgage loans underlying privately issued mortgage-backed securities may have less favorable collateral, credit risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The market for non-agency mortgage-backed securities is smaller and less liquid than the market for agency mortgage-backed securities.

 

Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary as interest rates rise or fall. An increased rate of prepayments on the Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. The prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise. The liquidity of mortgage-backed securities, and particularly non-agency non-investment grade mortgage-backed securities, may change dramatically over time.

 

Mortgage-backed securities may be backed by mortgage loans across the spectrum of credit quality. Lower credit quality mortgage loans, such as those considered “subprime,” are more likely to default than those considered “prime” by a rating agency or service provider. Mortgage-backed securities supported by subprime mortgage loans generally carry a higher risk of loss and are potentially less liquid than mortgage-backed securities supported by prime mortgage loans, as an economic downturn or period of rising interest rates could adversely affect the market for sub-prime mortgage loans and thereby reduce the Fund’s ability to sell securities backed by such loans. Additionally, subprime loan borrowers may seek bankruptcy protection which would delay resolution of security holder claims and may eliminate or materially reduce liquidity.

 

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons, including the following:

 

The Fund incurs operating expenses not applicable to the 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 Index.

 

The performance of the Fund and the Index may vary due to asset valuation differences: the Fund may fair value certain of the securities it holds and to the extent it calculates its NAV based on fair value prices, the Fund’s ability to track the Index may be adversely affected.

 

There may be differences between the Fund’s portfolio and the Index as a result of legal restrictions, cost or liquidity constraints. For example, the Index is not subject to the tax diversification requirements to which the Fund must adhere; so the Fund may be required to deviate its investments from the securities and relative weightings of the Index. Similarly, the Fund may not invest in certain securities included in the Index due to liquidity constraints. Liquidity constraints also may delay the Fund’s purchase or sale of securities included in the Index.

 

The investment activities of one or more of the Advisor’s affiliates for their proprietary accounts and for client accounts may also adversely impact the Fund’s ability to track the Index. For example, in regulated industries, and in corporate and regulatory ownership definitions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded, or that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause the Advisor, the Fund or other client accounts to suffer disadvantages or business restrictions. As a result, the Fund may be restricted in its ability to acquire particular securities due to positions held by the Advisor’s affiliates.

 

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

 

Preferred Stock Risk. Typically, a rise in interest rates causes a decline in the value of preferred stocks. Preferred stocks are also subject to credit and default risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payment. Issuers of preferred stocks may redeem their securities prior to maturity at a price below their current market value which would negatively impact the investment return of such preferred stocks.

 

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

 

Real Estate/REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.

 

Sampling Risk. The sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

 

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index, transaction and financing costs related to the use of derivatives or the need to meet various regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

 

Underlying Fund Risk. Other investment companies, including ETFs (“Underlying Funds”), in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks and is also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be illiquid or even halted under certain circumstances. Certain additional risks of investing in ETFs are described below:

 

Net Asset Value and Market Price Risk: The market value of ETF shares may differ from their net asset value. This difference in price may be due to the fact that the supply and demand in the market for fund shares at any point in time is not always identical to the supply and demand in the market for the underlying basket of securities. Accordingly, there may be times when shares trade at a premium or discount to net asset value.

 

Utilities Sector Risk. Companies in the utilities sector are subject to a variety of factors that may adversely affect their business or operations, including high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital in periods of high inflation and unsettled capital markets; governmental regulation of rates the issuer can charge to customers; costs associated with compliance with environmental and other regulations; effects of economic slowdowns and surplus capacity; increased competition; and potential losses resulting from a developing deregulatory environment.

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with Foreside Fund Services, LLC, the Fund’s distributor (the “Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Changing Fixed Income Market Conditions Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

Risk [Text Block] rr_RiskTextBlock

Duration Risk. Longer-term securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the rise in a security’s price. For example, a five-year duration means that the fixed income security will decrease in value by 5% if interest rates rise 1% and increase in value by 5% if interest rates fall 1%.

Risk [Text Block] rr_RiskTextBlock

ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Risk [Text Block] rr_RiskTextBlock

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. The maturity and effective duration of the Fund’s investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Junk Bond Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Junk Bond Risk. Lower-quality bonds, known as “high-yield” or “junk” bonds, are considered to be speculative with respect to the issuer’s ability to pay interest and principal when due and present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell the bonds in its portfolio. The lack of a liquid market for these bonds could decrease the value of the Fund’s portfolio and net asset value per share.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Mortgage Backed Securities Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Mortgage-Backed Securities Risk. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which mortgage loans are guaranteed by the U.S. government, its agencies or instrumentalities. These guarantees are made at the “loan level” and relate only to the payment of principal and interest on the underlying mortgage loans. These loan-level governmental guarantees do not cover the payment of principal and interest on, or fluctuations in the market values of, the related mortgage-backed securities, and do not apply to investors’ purchase of shares of the Fund.

Mortgage-backed securities issued or guaranteed by governmental agencies or instrumentalities such as Ginnie Mae, or government-sponsored entities such as Fannie Mae and Freddie Mac, are generally known as “agency mortgage-backed securities.” Agency mortgage-backed securities are backed by mortgage loans that satisfy the underwriting and other criteria published by the applicable governmental entity. The payment of interest and principal on these mortgage-backed securities is generally guaranteed by the applicable governmental entity.

 

Mortgage-backed securities issued by private issuers are also known as “non-agency” mortgage-backed securities. Non-agency mortgage-backed securities are not subject to the same stringent underwriting requirements as agency mortgage-backed securities and, therefore, the mortgage loans underlying privately issued mortgage-backed securities may have less favorable collateral, credit risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The market for non-agency mortgage-backed securities is smaller and less liquid than the market for agency mortgage-backed securities.

 

Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary as interest rates rise or fall. An increased rate of prepayments on the Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. The prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise. The liquidity of mortgage-backed securities, and particularly non-agency non-investment grade mortgage-backed securities, may change dramatically over time.

 

Mortgage-backed securities may be backed by mortgage loans across the spectrum of credit quality. Lower credit quality mortgage loans, such as those considered “subprime,” are more likely to default than those considered “prime” by a rating agency or service provider. Mortgage-backed securities supported by subprime mortgage loans generally carry a higher risk of loss and are potentially less liquid than mortgage-backed securities supported by prime mortgage loans, as an economic downturn or period of rising interest rates could adversely affect the market for sub-prime mortgage loans and thereby reduce the Fund’s ability to sell securities backed by such loans. Additionally, subprime loan borrowers may seek bankruptcy protection which would delay resolution of security holder claims and may eliminate or materially reduce liquidity.

Risk [Text Block] rr_RiskTextBlock

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Derivatives Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

 

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option’s strike price. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

 

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk, and sub-strategy risk.

 

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the fund to effectively implement its investment strategy, achieve its objectives and could potentially lead to significant losses.

 

Swaps Risk. Total return swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to replace. Total return over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The Fund’s use of swaps involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and exposes the Fund to the risks associated with derivative instruments described above. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

Written Call Option Risk. Selling covered call or stock index options will limit the Fund’s gain, if any, on its underlying securities. Losses on stock index options may only be partially offset by gains in the Fund’s portfolio if the portfolio does not track the call-related stock index. The Fund continues to bear the risk of a decline in the value of its underlying stocks. Option premiums are treated as short-term capital gains and when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account.

Concentration Risk. The Fund will concentrate its investments in securities of a particular industry to the extent the Index does. Economic, legislative or regulatory developments may occur that significantly affect the industry. This may cause the Fund’s net asset value or market price to fluctuate more than that of a fund that does not concentrate in a particular industry.

Risk [Text Block] rr_RiskTextBlock

Distribution Policy Risk. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Fixed Income Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Fixed Income Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default). Lowered credit ratings may cause a drop in a fixed income security’s price and are associated with greater risk of default on interest and principal payments. Certain fixed income securities may be paid off early when the issuer can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income. If interest rates rise, repayments of principal on certain fixed income securities may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result, which reduces the Fund’s ability to reinvest at higher rates. These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Index Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Index Related Risk [Member]

Risk [Text Block] rr_RiskTextBlock

Index-Related Risk. There is no assurance that the Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Index is designed to achieve, the Index Provider does not guarantee the quality, accuracy or completeness of data in respect of its indices, and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Issuer Specific Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Passive Investment Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Sampling Risk [Member]

Sampling Risk. The sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Tracking Error Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index, transaction and financing costs related to the use of derivatives or the need to meet various regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Build America Bonds Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Build America Bonds Risk. Build America Bonds involve similar risks as municipal bonds, including credit and market risk. In particular, should a Build America Bond’s issuer fail to continue to meet the applicable requirements imposed on such bonds, it is possible that such issuer may not receive federal cash subsidy payments, impairing the issuer’s ability to make scheduled interest payments. The Build America Bond program expired on December 31, 2010, and no further issuance is permitted unless Congress were to renew the program at a future date. As a result, the number of available Build America Bonds is limited, which may negatively affect the value of the Build America Bonds. In addition, there can be no assurance that Build America Bonds will be actively traded. It is difficult to predict the extent to which a market for such bonds will continue, meaning that Build America Bonds may experience greater illiquidity than other municipal obligations. The Build America Bonds outstanding as of December 31, 2010, will continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program will be eligible for the federal tax subsidy.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Cash Transactions Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Cash Transactions Risk. ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions partly or entirely in cash, rather than in-kind, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, could be imposed on the Fund and thus decrease the Fund’s NAV to the extent they are not offset by the creation and redemption transaction fees paid by purchasers and redeemers of Creation Units.

Dividend Yield Risk.

Early Close/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 prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.

Risk [Text Block] rr_RiskTextBlock

ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be halted under certain circumstances. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than the Fund that invests directly in individual securities.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | Leverage Risk [Member]

Leverage Risk. The use of leverage can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of funds that do not use such techniques.

 

Strategy Shares Nasdaq 7 HANDL(TM) Index ETF | M L P And M L P Related Securities Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

MLP and MLP-Related Securities Risk. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised) and risks related to the general partner’s limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Depending on the state of interest rates in general, the use of MLPs or MLP-related securities could enhance or harm the overall performance of the Fund.

 

MLP Tax Risk. MLPs do not pay U.S. federal income tax at the partnership level, subject to the application of certain partnership audit rules. Instead, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction of the value of your investment in the Fund and lower income, as compared to an MLP that is not taxed as a corporation.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons, including the following:

 

The Fund incurs operating expenses not applicable to the 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 Index.

 

The performance of the Fund and the Index may vary due to asset valuation differences: the Fund may fair value certain of the securities it holds and to the extent it calculates its NAV based on fair value prices, the Fund’s ability to track the Index may be adversely affected.

 

There may be differences between the Fund’s portfolio and the Index as a result of legal restrictions, cost or liquidity constraints. For example, the Index is not subject to the tax diversification requirements to which the Fund must adhere; so the Fund may be required to deviate its investments from the securities and relative weightings of the Index. Similarly, the Fund may not invest in certain securities included in the Index due to liquidity constraints. Liquidity constraints also may delay the Fund’s purchase or sale of securities included in the Index.
The investment activities of one or more of the Advisor’s affiliates for their proprietary accounts and for client accounts may also adversely impact the Fund’s ability to track the Index. For example, in regulated industries, and in corporate and regulatory ownership definitions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded, or that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause the Advisor, the Fund or other client accounts to suffer disadvantages or business restrictions. As a result, the Fund may be restricted in its ability to acquire particular securities due to positions held by the Advisor’s affiliates.

Preferred Stock Risk. Typically, a rise in interest rates causes a decline in the value of preferred stocks. Preferred stocks are also subject to credit and default risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payment. Issuers of preferred stocks may redeem their securities prior to maturity at a price below their current market value which would negatively impact the investment return of such preferred stocks.

Real Estate/REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.

Risk [Text Block] rr_RiskTextBlock
Net Asset Value and Market Price Risk: The market value of ETF shares may differ from their net asset value. This difference in price may be due to the fact that the supply and demand in the market for fund shares at any point in time is not always identical to the supply and demand in the market for the underlying basket of securities. Accordingly, there may be times when shares trade at a premium or discount to net asset value.

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 Fund 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 fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 245% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Newfound/ReSolve Robust Equity Momentum Index (the “Index”). The Index is based on a proprietary methodology co-developed and co-owned by Newfound Research LLC and ReSolve Asset Management SEZC (Cayman) (the “Index Providers”). The Index is calculated and maintained by Solactive AG. The Fund will invest at least 80% of its assets in the component securities of the Index.

 

The Index uses a quantitative, rules-based methodology to provide exposure to broad U.S. equity, international equity, and emerging market equity indices, to the extent that such equity indices are exhibiting positive momentum relative to U.S. Treasury market indices. The Index generally consists of exchange-traded funds (“ETFs”) that track regional equity indices, representative of U.S. equities, developed international equities and emerging market equities (“Regional Equity ETFs”), as well as ETFs that track U.S. Treasury market indices, representative of short-term (i.e., 1-2 year maturity) U.S. Treasury notes and intermediate-term (i.e., 7-10 year maturity) U.S. Treasury bonds (“U.S. Treasury ETFs”). The Regional Equity ETFs that may be included in the Index invest in the equity securities, including common stock and American Depository Receipts (“ADRs”), of companies of any market capitalization that are traded on foreign or U.S. exchanges. The Index typically includes between one and five ETFs. Because the Index is comprised of securities issued by other investment companies, the Fund operates as a “fund of funds.”

 

The allocations to Regional Equity ETFs within the Index are determined by proprietary quantitative models that include momentum and trend following factors that are evaluated over various time horizons. The weightings of Regional Equity ETFs within the Index are determined based on measures of the momentum of the global equity markets relative to the momentum of U.S. Treasury securities. Regional Equity ETFs with the strongest momentum characteristics that also exhibit positive trend following characteristics receive greater weights. The Fund may have 100% portfolio exposure to U.S. Regional Equity ETFs or developed international Regional Equity ETFs, and up to 25% portfolio exposure in emerging market Regional Equity ETFs.

 

The Index will include U.S. Treasury ETFs when Regional Equity ETFs exhibit negative momentum and trend following characteristics versus the U.S. Treasury markets. The Fund may have 100% portfolio exposure to U.S. Treasury ETFs under such circumstances.

 

The Index is rebalanced weekly and is reconstituted annually in December.

 

The Fund generally will use a replication methodology, meaning it will seek to invest in all of the ETFs comprising the Index in proportion to the weightings in the Index. However, under various circumstances, the Fund may use a representative sampling strategy, whereby the Fund would invest in what it believes to be a representative sample of the component securities of the Index. To the extent the Fund uses a representative sampling strategy, it may not track the Index with the same degree of accuracy as would an investment vehicle replicating the entire Index.

 

The Fund will concentrate its investments in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries. The Fund may engage in frequent trading of portfolio securities.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk [Text Block] rr_RiskTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value, market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests.

 

ADR Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies discussed below and involve risks that are not found in investments in U.S. companies. ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. Certain ADRs are not listed on an exchange and therefore may be considered to be illiquid.

 

ADR Currency Risk. To establish a value for the shares, the issuer establishes a “conversion rate” equal to one share of an ADR for a certain number of shares of the stock of a foreign company. This “conversion rate” establishes a universal monetary relationship between the value of the ADR and the local currency of the foreign company stock. Although an ADR is priced in the US dollar, in order to preserve the uniformity of the established “conversion rate,” movements in the exchange rate of the local currency versus the US dollar are automatically reflected in the price of the ADR in US dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the US Dollar declines, the ADR price would decline by a similar measure.

 

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

 

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Concentration Risk. The Fund will concentrate its investments in securities of a particular industry to the extent the Index does. Economic, legislative, or regulatory developments may occur that significantly affect the industry. This may cause the Fund’s net asset value or market price to fluctuate more than that of the Fund that does not concentrate in a particular industry.

 

Currency Risk. If a Regional Equity ETF invests in securities that trade in, and receive revenues in, foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. As a result, the Regional Equity ETF’s investments in foreign currency-denominated securities may reduce the Fund’s returns.

 

Early Close/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 prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.

 

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social, and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid, and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

 

Equity Securities Risk. The price of equity securities will fluctuate based on actual or perceived changes in a company’s financial condition and on market and economic conditions. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary, and fiscal policies; inflation and interest rates; economic expansion or contraction and global or regional political, economic and banking crises.

 

ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be halted under certain circumstances. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than the Fund that invests directly in individual securities.

 

ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory, or other events or conditions affecting countries within the specific geographic regions in which the Regional Equity ETFs invest. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund.

 

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

 

Index-Related Risk. There is no assurance that the Index will be determined, composed, or calculated accurately. While the Index Providers provide descriptions of what the Index is designed to achieve, the Index Providers do not guarantee the quality, accuracy or completeness of data in respect of its indices and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

 

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

 

Large Capitalization Stock Risk. Investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors potentially resulting in lower markets for their common stock. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

Management Risk. As the Fund may not fully replicate the Index, it is subject to the risk that investment management strategy may not produce the intended results.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s share price may decline suddenly or over a sustained period of time. Overall market risks may also affect the value of the Fund. Factors such as economic growth and market conditions, interest rate levels and political events affect the securities markets.

 

Mid/Small-Cap Stock Risk. The value of smaller and medium-capitalized company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

 

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Index carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections, or malfunctions. Because models are usually constructed based on data supplied by third parties, the success of the Index’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

 

Sampling Risk. The sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

 

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index or the need to meet various regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

 

Turnover Risk. The Fund may have a high turnover of the securities held in its portfolio. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

 

Underlying Fund Risk. The ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the ETFs and may be higher than other funds that invest directly in stocks and bonds. Each of the ETFs is subject to its own specific risks and are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be illiquid or even halted under certain circumstances.

 

U.S. Government Obligations Risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may not be backed by the full faith and credit of the U.S. government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

Risk [Text Block] rr_RiskTextBlock
Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s share price may decline suddenly or over a sustained period of time. Overall market risks may also affect the value of the Fund. Factors such as economic growth and market conditions, interest rate levels and political events affect the securities markets.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Model And Data Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Index carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections, or malfunctions. Because models are usually constructed based on data supplied by third parties, the success of the Index’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Underlying Fund Risk [Member]

Risk [Text Block] rr_RiskTextBlock

Underlying Fund Risk. The ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the ETFs and may be higher than other funds that invest directly in stocks and bonds. Each of the ETFs is subject to its own specific risks and are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be illiquid or even halted under certain circumstances.

U.S. Government Obligations Risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may not be backed by the full faith and credit of the U.S. government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Changing Fixed Income Market Conditions Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Changing Fixed Income Market Conditions Risk. The historically low interest rate environment observed over the past couple years was created in part by actions taken by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to keep the federal funds rate at a low level, including expanding the scope of its repurchase agreement operations, and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market. More recently the Federal Reserve began raising the federal funds rate in an effort to help fight inflation. Increases in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. Such policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund to decrease to the extent that it invests in fixed income securities.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Emerging Markets Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social, and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid, and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:

 

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

 

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

 

Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Fund shares and the Fund’s net asset value.

 

The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund shares or in the closing price.

 

When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

 

In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers maybe less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Geographic Concentration Risk [Member]

Risk [Text Block] rr_RiskTextBlock

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory, or other events or conditions affecting countries within the specific geographic regions in which the Regional Equity ETFs invest. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Concentration Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Concentration Risk. The Fund will concentrate its investments in securities of a particular industry to the extent the Index does. Economic, legislative, or regulatory developments may occur that significantly affect the industry. This may cause the Fund’s net asset value or market price to fluctuate more than that of the Fund that does not concentrate in a particular industry.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Index Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Index. Therefore, it would not necessarily sell a security unless that security is removed from the Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

Strategy Shares Newfound/Resolve Robust Momentum ETF | Index Related Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Index-Related Risk. There is no assurance that the Index will be determined, composed, or calculated accurately. While the Index Providers provide descriptions of what the Index is designed to achieve, the Index Providers do not guarantee the quality, accuracy or completeness of data in respect of its indices and does not guarantee that the Index will be in line with the described index methodology. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that losses resulting from errors may be borne by the Fund and its shareholders.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Issuer Specific Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Passive Investment Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Index. The Fund invests in securities included in, or representative of securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund, unless such defensive positions are also taken by the Index.

Strategy Shares Newfound/Resolve Robust Momentum ETF | Sampling Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Sampling Risk. The sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV or market price than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Tracking Error Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of imperfect correlation between the Fund’s holdings of portfolio securities and those in the Index, pricing differences, the Fund’s holding of cash, differences on timing of the accrual of dividends, changes to the Index or the need to meet various regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | Early Close Trading Halt Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

Early Close/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 prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | E T F Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop or be maintained; and (iii) market trading in the ETF may be halted under certain circumstances. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than the Fund that invests directly in individual securities.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | A D R Risk [Member]

Risk [Text Block] rr_RiskTextBlock

ADR Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies discussed below and involve risks that are not found in investments in U.S. companies. ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. Certain ADRs are not listed on an exchange and therefore may be considered to be illiquid.

 

Strategy Shares Newfound/Resolve Robust Momentum ETF | A D R Currency Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock

ADR Currency Risk. To establish a value for the shares, the issuer establishes a “conversion rate” equal to one share of an ADR for a certain number of shares of the stock of a foreign company. This “conversion rate” establishes a universal monetary relationship between the value of the ADR and the local currency of the foreign company stock. Although an ADR is priced in the US dollar, in order to preserve the uniformity of the established “conversion rate,” movements in the exchange rate of the local currency versus the US dollar are automatically reflected in the price of the ADR in US dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the US Dollar declines, the ADR price would decline by a similar measure.

Currency Risk. If a Regional Equity ETF invests in securities that trade in, and receive revenues in, foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. As a result, the Regional Equity ETF’s investments in foreign currency-denominated securities may reduce the Fund’s returns.

Risk [Text Block] rr_RiskTextBlock

Large Capitalization Stock Risk. Investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors potentially resulting in lower markets for their common stock. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Turnover Risk. The Fund may have a high turnover of the securities held in its portfolio. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

[10] The Fund’s investment advisor, Rational Advisors, Inc., has contractually agreed to waive all or a portion of its management fee and/or reimburse certain operating expenses of the Fund to the extent necessary in order to limit the Total Annual Fund Operating Expenses (exclusive of: (i) acquired fund fees and expenses; (ii) brokerage commissions and trading costs; (iii) interest (including borrowing costs and overdraft charges); (iv) taxes; (v) short sale dividends and interest expenses; and (vi) non-routine or extraordinary expenses (such as litigation or reorganizational costs) to not more than 0.75% of the Fund’s daily net assets through August 31, 2025. This arrangement may only be terminated prior to this date with the agreement of the Fund’s Board of Trustees. Under certain conditions, the Advisor may recoup management fees that it waived or Fund expenses that it paid under this agreement for a period of up to three years from the date the fees were waived and/or expenses paid, provided such recoupment can be achieved without causing the expense ratio (after the recoupment is taken into account) to exceed (i) the expense limit in effect at the time the fees were waived or expenses paid, or (ii) the expense limit in place at the time of the recapture.
