Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock The Defiance Quantum ETF (the “Fund” or the “Quantum ETF”) seeks to track the total return performance, before fees and expenses, of the BlueStar Quantum Computing and Machine Learning Index (the “Index”).
Expense [Heading] rr_ExpenseHeading Fees and Expenses of the Fund
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Operating Expenses Caption [Text] rr_OperatingExpensesCaption Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. For the fiscal year ended December 31, 2023, the Fund’s portfolio turnover rate was 31% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 31.00%
Expense Example [Heading] rr_ExpenseExampleHeading Expense Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then continue to hold or redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
BlueStar Quantum Computing and Machine Learning Index
The Index consists of a modified equal-weighted portfolio of the stock of companies that derive at least 50% of their annual revenue or operating activity from the development of quantum computing and machine learning technology. “Quantum computing” refers to hardware and software designed to take advantage of extremely fast computers that leverage the field of quantum mechanics, a branch of physics dealing with particles and the complexities in which they naturally behave. Such technologies include research and development of quantum computers; use of quantum computing for applied sciences or communications; development of technology-enabled interactions between quantum and traditional computers; development of advanced hardware and/or software used in machine learning; production of specialized machinery used in advanced semiconductor and integrated circuit packaging; or the production and/or processing of raw materials used in quantum computing. The companies included in the Index are screened semi-annually from the universe of globally-listed stocks (including in emerging markets) by BlueStar Global Investors, LLC (“BlueStar” or the “Index Provider”) based primarily on descriptions of a company’s primary business activities in regulatory filings (e.g., financial statements, annual reports, investor presentations), analyst reports, and industry-specific trade publications. Companies identified by BlueStar’s screening process are then screened for investibility, including a minimum market capitalization of US$150 million and minimum liquidity thresholds.
The Index is rebalanced and reconstituted semi-annually after the close of business on the third Friday of June and December each year based on data as of the Tuesday before the second Friday of June and December each year. However, new initial public offerings (“IPOs”) that meet the Index’s eligibility requirements may be added on a “fast-entry basis” in between reconstitution dates. In addition to the semi-annual reconstitutions in June and December, new IPOs are reviewed for fast-entry addition in March and September, and may be added after the close of business on the third Friday of March and September. Fast-entry additions are added at an equal weight with the weight reduced from existing components proportionally. Index constituents will be removed from the Index at the time of a reconstitution if they fail to meet the eligibility requirements.
In determining the companies included in the Index at the time of each rebalance and reconstitution of the Index, the largest eligible companies by market capitalization are included until 98.5% of the market capitalization of such eligible companies is included in the Index, plus any companies already included in the Index whose market capitalization is in the top 99.5% of the market capitalization of eligible companies. If such rules result in fewer than 70 Index components, the largest remaining eligible companies are selected until the number of components reaches 70.
As of March 31, 2024, the Index had 68 constituents, 18 of which were listed on a non-U.S. exchange. At the time of each rebalance and reconstitution of the Index, each constituent is equally-weighted, subject to a downward adjustment for securities trading below certain liquidity thresholds. Additionally, the weight of each Index component may rise and/or fall between Index rebalance dates.
The Index was established in 2018 and is owned by the Index Provider.
The Fund’s Investment Strategy
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of March 31, 2024, the Index was concentrated in the semiconductors industry and had significant exposure to other information technology sector industries, including the software industry group.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund.
Defiance Quantum ETF | Capital Controls And Sanctions Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.
Defiance Quantum ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Concentration Risk. The Fund’s investments will be concentrated in an industry or group of industries to the extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.
Defiance Quantum ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Defiance Quantum ETF | Depositary Receipt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.
Defiance Quantum ETF | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Emerging Markets Risk. The Fund may invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.
Defiance Quantum ETF | Emerging Technologies Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Emerging Technologies Investment Risk. The Fund invests primarily to gain exposure to emerging technologies, such as quantum computing, in accordance with the Index. Companies across a wide variety of industries, primarily in the technology and communications services sectors, are exploring the possible applications of these technologies. The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may be significantly tied to such industries. Currently, there are few public companies for which these emerging technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.
Defiance Quantum ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
Defiance Quantum ETF | ETF Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, , there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

Defiance Quantum ETF | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Risk Narrative [Text Block] rr_RiskTextBlock Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.
Defiance Quantum ETF | Index Methodology Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Index Methodology Risk. The Index may not include all companies around the globe whose products or services are predominantly tied to the development of quantum computing and machine learning technologies because the Index includes only those companies meeting the Index criteria. For example, companies that would otherwise be included in the Index might be excluded from the Index if they omit discussion of their quantum computing and machine learning technologies from descriptions of their business in regulatory filings or otherwise keep such work hidden from public (and the Index Provider’s) view.

Risk Narrative [Text Block] rr_RiskTextBlock Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Adviser relies upon the Index Provider and its agents to compile, determine, maintain, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders.
Defiance Quantum ETF | Market Capitalization Risk Member

Risk Narrative [Text Block] rr_RiskTextBlock Market Capitalization Risk
◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.
◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole.

Risk Narrative [Text Block] rr_RiskTextBlock Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
◦Information Technology Sector Risk. The Fund is generally expected to invest significantly in companies in the information technology sector, including the semiconductor industry, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect
profitability. Information technology companies and companies that rely heavily on technology may also be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. For the fiscal year ended December 31, 2023, the Fund’s portfolio turnover rate was 56% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
BlueStar 5G Communications Index
The Index is a rules-based index that consists of a tiered, modified market capitalization-weighted portfolio of the U.S.-listed equity securities, including depositary receipts, of companies whose products or services are predominantly tied to the development of 5G networking and communication technologies (collectively, “5G Companies”). 5G Companies are assigned to one of four segments of the 5G communications industry, as described below. At the time of each rebalance and reconstitution of the Index, each 5G Company is ranked by its free-float market capitalization. The maximum weight for any single stock is 5%. If a stock exceeds the maximum weight, then the weight will be reduced to the maximum weight and the excess weight shall be redistributed proportionally across all other index constituents. This process is repeated until no stocks have weights exceeding the respective maximum weight. Additionally, to qualify for inclusion in the Index, a 5G Company must have a minimum market capitalization of $150 million, and must meet certain liquidity, free-float (i.e., the percentage of shares available to the public), and trading cost thresholds.
Segment 1 - consists of 5G Companies whose products or services are predominantly tied to core cellular network equipment (e.g., carrier-grade routers, antennas, or other equipment or semiconductors used in 5G networks).
Segment 2 - consists of 5G Companies (i) that are organized as cellphone tower or data center real estate investment trusts (“REITs”), (ii) that predominantly provide services as a mobile network operator (“MNO”). REITs and MNOs must have a minimum market capitalization of $1 billion to be included in the Index.
Segment 3 - consists of 5G Companies whose products or services are predominantly tied to (i) hardware and software focused on quality of service assurance for MNOs and media companies, (ii) network testing and bandwidth optimization equipment, (iii) network or cloud operations and analytics platforms with mobile network and 5G-related use cases, or (iv) edge computing equipment and related services.
Segment 4 - consists of 5G Companies whose products or services are predominantly tied to (i) enhanced mobile broadband (eMBB) modems capable of increased bandwidth for end-user devices or (ii) whose products or services are predominantly tied to the infrastructure or cloud-based services supporting REITs and MNOs.
The companies included in the Index are screened from the universe of global companies with equity securities or depositary receipts listed on a U.S. exchange by MarketVector Indexes Gmb (“MarketVector” or the “Index Provider”) based primarily on descriptions of a company’s primary business activities in regulatory filings (e.g., financial statements, annual reports, investor presentations), analyst reports, and industry-specific trade publications. 5G Companies identified by MarketVector’s screening process are added to the Index, subject to meeting the investibility requirements described above. The Index may include small-, mid-, and large-capitalization companies.
Only the three largest investable REITs and the three largest investable MNOs are included in the Index’s eligible universe, all investable companies from other segments are included in the eligible universe. The Index includes 50 constituents. The 40 largest members of the eligible universe based on float-adjusted market capitalization are automatically included. The next 10 companies are selected from the largest current Index constituents ranked in the top 60. If fewer than 50 constituents have been selected, the next largest members of the eligible universe will be selected until 50 constituents are selected.
The Index is rebalanced and reconstituted semi-annually after the close of business on the third Friday of each March and September based on data as of the first Thursday of each such reconstitution month. At the time of each rebalance and reconstitution of the Index, each constituent is weighted as described above, subject to a downward adjustment for securities trading below certain liquidity thresholds. Additionally, the weight of each Index component may rise and/or fall between Index rebalance dates.
To reduce turnover, existing Index components will not be removed from the Index solely for not meeting the minimum market capitalization or liquidity criteria unless they do not meet such requirements for two consecutive reconstitutions.
The Index was established in 2019 and is owned by the Index Provider.
The Fund’s Investment Strategy
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of March 31, 2024, the Index was concentrated in the semiconductor industry and had significant exposure to the communications equipment industry.

Risk Narrative [Text Block] rr_RiskTextBlock 5G Investment Risk. Companies across a wide variety of industries, primarily in the technology sector, are exploring the possible applications of 5G technologies. The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that focus on or have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may not be significantly tied to such technologies. Currently, there are few public companies for which 5G technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.
Defiance Next Gen Connectivity ETF | Capital Controls And Sanctions Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.
Defiance Next Gen Connectivity ETF | Concentration Risk Member

Risk Narrative [Text Block] rr_RiskTextBlock Concentration Risk. The Fund’s investments will be concentrated in an industry or group of industries to the extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.
Defiance Next Gen Connectivity ETF | Depositary Receipt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.
Defiance Next Gen Connectivity ETF | Emerging Technologies Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Emerging Technologies Investment Risk. The Fund invests primarily to gain exposure to emerging technologies, such as 5G technologies, in accordance with the Index. Companies across a wide variety of industries, primarily in the technology sector, are exploring the possible applications of these technologies. The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may be significantly tied to such industries. Currently, there are few public companies for which these emerging technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.
Defiance Next Gen Connectivity ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. securities also may be subject to withholding or other taxes.

◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.
◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole.

Risk Narrative [Text Block] rr_RiskTextBlock REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income.
Defiance Next Gen Connectivity ETF | Sector Risk Member

Risk Narrative [Text Block] rr_RiskTextBlock Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
◦Communications Services Sector Risk. The Fund is generally expected to invest significantly in companies in the communications services sector, including those in the communications equipment industry, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of such companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.
◦Information Technology Sector Risk. The Fund is generally expected to invest significantly in companies in the information technology sector, including those in the semiconductor industry, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s
investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Information technology companies and companies that rely heavily on technology may also be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions.

The Fund is generally expected to invest significantly in companies in the information technology sector, including those in the semiconductor industry, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Information technology companies and companies that rely heavily on technology may also be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions.

Risk Narrative [Text Block] rr_RiskTextBlock Securities Lending Risk. There are certain risks associated with securities lending, including the risk that the borrower may fail to return the securities on a timely basis or even the loss of rights in the collateral deposited by the borrower, if the borrower should fail financially. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. As a result, the Fund may lose money.

The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
BlueStar Hydrogen & NextGen Fuel Cell Index
The Index is a rules-based index that tracks the performance of a group of globally listed equity securities of companies involved in the development of hydrogen-based energy sources and fuel cell technologies. The Index is predominantly comprised of “pure-play” companies, i.e., those that generate at least 50% of their revenues from products that facilitate hydrogen-based energy production, including fuel cells capable of using hydrogen as a fuel source (collectively, “H2 Companies”). At the time of each quarterly reconstitution of the Index, pure-play companies will comprise at least 85% of the weight of the Index.
Up to 15% of the Index’s weight, at the time of each quarterly reconstitution, may be comprised of “non-pure-play” companies, i.e., those that are engaged in hydrogen or hydrogen-based fuel cell projects, including the production of hydrogen and other industrial gases, and either have the potential to become pure-play companies or that play a significant role in the global hydrogen or fuel cell segment. Vehicle manufacturers are not eligible for inclusion in the Index. The Index may include companies in developed countries, including the United States, as well as emerging market countries.
At the time of each quarterly reconstitution of the Index, MV Index Solutions GmbH (the “Index Provider”) identifies the universe of pure-play and non-pure-play companies. To be eligible for being added to the Index, such companies must meet investibility requirements (the “Investibility Requirements”), including:
•a market capitalization of at least US$150 million that is within the top 85% of the free-float market capitalization of the universe of pure-play companies;
•a 3-month average daily value traded greater than or equal to US$1 million;
•250,000 shares traded per month over the prior six months; and
•a free float (i.e., the proportion of shares that are publicly available) of at least 10%.
Once included in the Index, companies are eligible to remain in the Index at lower investibility thresholds.
At the time of each quarterly reconstitution of the Index, pure-play companies are added to the Index based on their free-float market capitalization (from largest to smallest) until their aggregate free-float market capitalization is at least 90% of the free-float market capitalization of all pure-play companies meeting the Investibility Requirements. In the event the Index would include fewer than 25 pure-play companies, the Index will include non-pure-play companies (from largest to smallest based on their free-float market capitalization) meeting the Investibility Requirements and, if necessary, add the next largest pure-play or non-pure-play company that does not meet the Investibility Requirements until there are a minimum of 25 companies in the Index.
At the time of each quarterly reconstitution of the Index, Index constituents are weighted using a modified market-capitalization methodology that establishes a minimum aggregate weight of 85% for pure-play companies, limits the weight of any individual security to 10% (4% for industrial gas companies), and adjusts the weight of a constituent downward based on certain liquidity criteria. Excess weight resulting from the above adjustments is redistributed among the remaining constituents. Additionally, at the time of each rebalance of the Index, the aggregate weight of constituents with a weight greater than or equal to 5% is limited to 50%, and the weight of the smallest constituent(s) that would otherwise cause the Index to exceed the 50% threshold and all other constituents with a weight greater than 4.5% but less than 5% will be set to 4.5%.
The Index is reconstituted quarterly, effective after the close of trading on the third Friday of each March, June, September, and December (the “Rebalance Date”). For each rebalance and reconstitution of the Index, Index constituents and their weights are determined based on data prior to the Rebalance Date.
As of March 31, 2024, the Index was composed of 25 constituents. The Index was established in 2021 and is owned and maintained by the Index Provider. The Index Provider partnered with the Fund’s investment adviser to co-develop the methodology used to determine the securities included in the Index.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s net assets (plus borrowings for investment purposes) will be invested in H2 Companies (as described above).
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index is expected to be concentrated in hydrogen and fuel cell companies.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Defiance Next Gen H2 ETF | Concentration In Hydrogen And Fuel Cell Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Concentration in Hydrogen and Fuel Cell Companies Risk. The Fund’s investments will be concentrated in an industry or group of industries to the extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. The Index is expected to be concentrated in hydrogen and fuel cell companies. Such companies may depend largely on the availability of hydrogen gas, certain third-party key suppliers for components in their products, and a small number of customers for a significant portion of their business. Hydrogen and fuel cell companies are also subject to risks related to the obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions that significantly affect the hydrogen, fuel cell, and overall clean energy industry. Risks associated with hazardous materials, fluctuations in energy prices and supply and demand of alternative energy fuels, energy conservation, the success of exploration projects and tax and other government regulations can also significantly affect this industry. Shares in the companies involved in this industry may be significantly more volatile than shares of companies operating in other, more established industries.
Defiance Next Gen H2 ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund may invest a relatively large percentage of its assets in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Defiance Next Gen H2 ETF | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments. For example, developing and emerging markets may be subject to (i) greater market volatility, (ii) lower trading volume and liquidity, (iii) greater social, political and economic uncertainty, (iv) governmental controls on foreign investments and limitations on repatriation of invested capital, (v) lower disclosure, corporate governance, auditing and financial reporting standards, (vi) fewer protections of property rights, (vii) fewer investor rights and limited legal or practical remedies available to investors against emerging market companies, (viii) restrictions on the transfer of securities or currency, and (ix) settlement and trading practices that differ from those in U.S. markets. Each of these factors may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. Additionally, limitations on the availability of financial and business information about companies in emerging markets may affect the Index Provider’s ability to accurately determine the companies meeting the Index’s criteria.
Defiance Next Gen H2 ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.
◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.
◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Code.

There are certain risks associated with securities lending, including the risk that the borrower may fail to return the securities on a timely basis or even the loss of rights in the collateral deposited by the borrower, if the borrower should fail financially. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. As a result, the Fund may lose money.
Defiance Next Gen H2 ETF | Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Tax Risk. To qualify for the favorable tax treatment generally available to a RIC, the Fund must satisfy, among other requirements described in the SAI, certain diversification requirements. Given the concentration of the Index in a relatively small number of issuers, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could be eligible for relief provisions if the failure is due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. If the Fund were to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, its shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
BlueStar Global Hotels, Airlines, and Cruises Index
The Index is a rules-based index that consists of globally-listed stocks of companies that derive at least 50% of their revenues from the passenger airline, hotel and resort, or cruise industries (“Travel Companies”) as determined by MV Index Solutions GmbH (the “Index Provider”). The Index may include companies in developed countries, including the United States, as well as emerging market countries. To be added to the Index, an Index component must meet the Index’s investibility and liquidity requirements, including a market capitalization greater than or equal to US$150 million, and once included in the Index, companies are eligible to remain in the Index at reduced investibility and liquidity thresholds (collectively, the “Investibility Requirements”).
At the time of each semi-annual reconstitution of the Index, Travel Companies meeting the Investibility Requirements are added to the Index based on their free-float market capitalization (from largest to smallest) until their aggregate free-float market capitalization is at least 95% of the free-float market capitalization of all Travel Companies meeting the Investibility Requirements with at least 25 Travel Companies. If such rules result in fewer than 25 Index components, the largest remaining eligible companies are selected until the number of components reaches 25.
At the time of each quarterly rebalance of the Index, the Index components are initially weighted by their float-adjusted market capitalization and separated into three tiers: (i) hotels, (ii) airlines, and (iii) cruises. If the aggregate weight of any tier would exceed 50%, then that tier’s weight is set to 50% and the excess weight is distributed to the other two tiers on a pro-rata basis. If the weight of any tier would be less than 15%, that tier’s weight is set to 15% and the difference is subtracted from the other two tiers on a pro-rata basis. Index components are then weighted based on their float-adjusted market capitalization within each tier, subject to a maximum weight of 8% for any individual security and adjustments downward based on certain liquidity criteria. Excess weight resulting from such adjustments is redistributed among the remaining constituents in the applicable tier.
The Index is reconstituted semi-annually after the close of business on the third Friday of each March and September and rebalanced quarterly on the third Friday of each March, June, September, and December based on data as of the last business day of the month prior to such reconstitution or rebalance.
As of March 31, 2024, the Index was composed of 55 constituents, 20 of which were listed on a non-U.S. exchange. The Index was established in 2021 and is owned and maintained by the Index Provider. The Index Provider partnered with the Fund’s investment adviser to co-develop the methodology used to determine the securities included in the Index. The Index Provider is not affiliated with the Fund or its investment adviser, sub-adviser, or distributor.
The Fund’s Investment Strategy
Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in Travel Companies. The foregoing policy may be changed without shareholder approval upon 60 days’ written notice to shareholders.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to be concentrated in Travel Companies.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Concentration in Travel Companies Risk. The Fund’s investments will be concentrated in an industry or group of industries to the extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. Travel Companies may be adversely affected by a downturn in economic conditions that can result in decreased demand for leisure and business travel. Due to the discretionary nature of business and leisure travel spending, Travel Company revenues are heavily influenced by the condition of the U.S. and foreign economies. Travel Companies may also be significantly affected by changes in labor relations and insurance costs. Travel Companies in the airline and cruise industries may also be significantly affected by changes in fuel prices, which may be very volatile and may not be able to be passed on to customers by increasing fares. Airline companies may also be highly dependent on aircraft or related equipment from a small number of suppliers, and consequently, issues affecting the availability, reliability, safety, or longevity of such aircraft or equipment (e.g., the inability of a supplier to meet aircraft demand or the grounding of an aircraft due to safety concerns) may have a significant effect on the operations and profitability of airline companies. Companies in the hotel and lodging industry, as well as the cruise industry, are subject to various risks that may cause significant losses, which includes risks related to uncertainty in travel (due to global, regional or local events), guest safety, security, and privacy, changing consumer demands, shortages of experienced personnel, consumer perception of risk (for example, due to terrorist attacks, pandemics, and political or social violence), and changing or increased regulations.
Beginning in the first quarter of 2020, some sectors of the economy and individual issuers, including Travel Companies, experienced particularly large losses due to the global pandemic caused by COVID‑19, a novel coronavirus. The pandemic resulted in a wide range of social and economic disruptions, including closed borders and reduced or prohibited domestic or international travel. Such disruptions may reoccur in the future to a similar or greater extent. Travel restrictions imposed in the United States and other countries resulted in airline, hotel, and cruise companies seeing dramatically reduced demand. In particular, certain U.S. passenger airlines and cruise companies eliminated nearly all international flights and voyages, respectively, for an undetermined length of time. The U.S. airline industry requested and received financial assistance from the U.S. government due to the impact of the pandemic; however, there can be no guarantee as to whether such assistance will be successful in supporting U.S. airline companies until the full impact of the pandemic subsides.
In addition, the Russian invasion of Ukraine and the resulting sanctions by Western countries on Russia, as well as retaliatory measures by Russia, may have a significant impact on Travel Companies. Bans on oil and energy imports from Russia by certain Western countries may increase the costs of travel, including jet fuel, gasoline, and fuel used in cruise liners. In addition, certain Western nations have closed their airspace and ports to all Russian aircraft and shipping vessels, respectively, and/or seized leased aircraft located in Western airports. In response, Russia has closed its airspace and ports to certain Western aircraft and shipping vessels, and Russia has seized certain leased aircraft located in Russia. These actions may lead to higher ticket prices, flight and cruise cancellations, longer routes, fewer diversion airports, a decreased demand for travel, and the permanent loss of property for Western companies. These and any related events could significantly and adversely affect the Fund’s performance and the value of an investment in the Fund.

Risk Narrative [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund may invest a relatively large percentage of its assets in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Defiance Hotel, Airline, and Cruise ETF | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Emerging Markets Risk. The Fund may invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.
◦Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.
◦Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Fund’s exposure to the other risks described herein will likely increase.

Risk Narrative [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.
◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.

Risk Narrative [Text Block] rr_RiskTextBlock Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. securities may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks.

Risk Narrative [Text Block] rr_RiskTextBlock Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

◦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 such companies 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.
◦Industrials Sector Risk. The industrials sector can be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, tariffs and trade barriers, and tax and governmental regulatory policies. As the demand for, or prices of, industrials increase, the value of the Fund’s investments generally would be expected to also increase. Conversely, declines in the demand for, or prices of, industrials generally would be expected to contribute to declines in the value of such securities.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index. The Index is comprised of global Israeli companies, across all sectors of the economy, irrespective of their listing venue.
The Fund’s Investment Strategy
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in Israeli Shekel (“ILS”)- and United States dollar (“USD”)-denominated debt, specifically bonds, issued by (i) the Israeli government, (ii) Israeli government-related entities or agencies, or (iii) Israeli companies (collectively, the “Israel Bonds”). The Fund defines “Israeli companies” as companies that are (a) domiciled in Israel or included in the BlueStar® Israel Global Index universe (generally, companies that derive a majority of their revenue from Israel); and (b) incorporated in Israel, the United States, the United Kingdom, or Jersey and Guernsey, Channel Islands.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.
MCM-BlueStar® Israel Bonds Index
Securities must meet the following eligibility criteria to qualify for inclusion in the Index:
•ILS-denominated bonds must be listed on the Tel Aviv Stock Exchange
•at least 18 months to final maturity at the time of issuance
•at least six months remaining to final maturity (with the next call date used at the maturity date for callable bonds)
•up to 15 years remaining to maturity for corporate bonds or 30 years for government bonds (with the next call date used at the maturity date for callable bonds)
•a minimum amount outstanding of at least $100 million for USD-denominated bonds or $250 million for ILS-denominated bonds
•trade in denominations of up to $10,000 USD (except for USD-denominated bonds of issuers incorporated in the United States)
•ILS-denominated corporate bonds must be rated as investment grade and USD-denominated corporate bonds must be rated BB- or higher (including “junk bonds”) according to S&P Global Ratings (“S&P”).
Securities are selected to the Index, as discussed below, with a minimum of 15 issuers represented in the Index, a maximum of 10 securities issued by the Israeli government or government-related entities, and a maximum of 5 securities issued by any one corporate issuer (based on the parent company). In the Index methodology described below, “largest” refers to the market value of the security.
•The 15 largest USD-denominated bonds, with a maximum of one bond per issuer, are selected to the Index. If fewer than 15 issuers have eligible USD-denominated bonds, the next largest ILS-denominated bonds are selected.
•The next 4 largest bonds (selecting from USD-denominated bonds first) issued by the Israeli government or government-related entities are selected.
•The next largest bonds (selecting from USD-denominated bonds first) are selected until a total of 35 bonds have been selected to the Index (subject to the issuer limitations set forth above).
The Index uses a modified market cap weighting methodology that caps a security’s weight at 5%, caps the combined aggregate weight of securities issued by the Israeli government and securities issued by Israeli government-related entities at 25%, and caps the aggregate weight of securities issued by any single corporate issuer at 7.5%. All securities selected to the Index are initially weighted based on their market value, subject to the following modifications:
•Step 1 - If the combined aggregate weight of securities issued by the Israeli government and securities issued by Israeli government-related entities exceeds 25%, or securities issued by any corporate issuer exceeds 7.5%, the weight of those securities will be reduced such that their aggregate weight equals 25% or 7.5%, respectively, with the remaining weight redistributed to all securities from non-capped issuers in proportion to their market value. This step is repeated until the aggregate weight of all securities from any single corporate issuer is less than or equal to 7.5%.
•Step 2 - If the weight of any single security exceeds 5%, the weight of that security is reduced to 5% with the remaining weight redistributed to all remaining uncapped securities from uncapped issuers. If the 5% security cap causes the aggregate weight of securities issued by the Israeli government or government-related entities to fall below 25%, or the aggregate weight of securities issued by any single corporate issuer to fall below 7.5%, those issuers will now be considered uncapped.
•Step 3 - Steps 2 and 3 are repeated until no security has a weight of more than 5%, the aggregate weight of all securities issued by the Israeli government or government-related entities is less than or equal to 25%, and the aggregate weight of securities from any single corporate issuer is less than or equal to 7.5%.
The Index is reviewed and rebalanced monthly. The Index was established in 2023 and is owned and maintained by MarketVector Indexes GmbH (the “Index Provider”), which owns the BlueStar® trademark.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Associated Risks of Israeli Investments. Investments in Israeli issuers may subject the Fund to legal, security, regulatory, political, and economic risk specific to Israel. Israel’s economy is dependent upon external trade with other economies, notably the United States, China, Japan, Canada, the United Kingdom, and European Union countries. As a result, economic conditions of Israel may be particularly affected by changes in the economy of or political relations between Israel and its key trading partners. Israel’s access to credit in the international capital markets is affected by regional and international political and economic conditions, including interest rates in financial markets outside Israel, the impact of changes in the credit rating of Israel, the global, regional and Israeli security situations, the economic growth and stability of Israel’s major trading partners and the global high-tech market. As a result, political, economic or market factors, which may be outside Israel’s control, may impact the debt dynamics of Israel and could adversely affect Israel’s cost of funds in the international capital markets and the liquidity of and demand for Israel’s debt securities. In addition, any negative change in the credit rating of Israel could adversely affect the trading price of Israel’s debt securities. Israel has experienced a history of hostile relations with several countries in the Middle East region. Israel and its citizens have also been the target of periodic acts of terrorism, including from U.S.-designated terrorist groups that are committed to violence against Israel, such as Hezbollah, the “Islamic State”, and Hamas, each of which operate in close proximity to Israel’s borders and frequently threaten Israel with attack. Attacks or threats from these groups have the potential to disrupt economic activity in Israel. Most recently, Hamas militants launched a brutal terror attack against southern Israel on October 7, 2023, and, in response, Israel declared war on Hamas and Israeli Defense Forces invaded the Gaza Strip. Actual hostilities, such as the Israel-Hamas war, or the threat of future hostilities may cause significant volatility in the share price of companies based in or having significant operations in Israel. Israel is located in a part of the world that has historically been prone to natural disasters such as earthquakes and droughts, and Israel is economically sensitive to environmental events. Any such event may adversely impact Israel’s economy or business operations of companies in Israel, causing an adverse impact on the value of the Fund.

Defiance Israel Fixed Income ETF | ETF Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.
◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Risk Narrative [Text Block] rr_RiskTextBlock Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Defiance Israel Fixed Income ETF | ETF Risks, Shares May Trade At Prices Other Than NAV Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.

Risk Narrative [Text Block] rr_RiskTextBlock Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Risk Narrative [Text Block] rr_RiskTextBlock Fixed Income Securities Risk. The value of investments in fixed income securities fluctuates with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned indirectly by the Fund. On the other hand, if rates fall, the value of the fixed income securities generally increases. Below are several specific risks associated with investments in fixed income securities.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Duration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Duration Risk. Prices of fixed income securities with longer durations are more sensitive to interest rate changes than those with shorter durations.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Event Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Extension Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Maturity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Maturity Risk. The value of fixed income investments is also dependent on their maturity. Generally, the longer the maturity of a fixed income security, the greater its sensitivity to changes in interest rates.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Prepayment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated and the proceeds may have to be invested in securities with lower yields.
Defiance Israel Fixed Income ETF | Fixed Income Securities Risk, Variable And Floating Rate Instrument Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Variable and Floating Rate Instrument Risk. Floating or variable rate securities pay interest at rates that adjust in response to changes in a specified interest rate or reset at predetermined dates (such as the end of a calendar quarter). Securities with floating or variable interest rates are generally less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as comparable market interest rates. Although floating or variable rate securities are generally less sensitive to interest rate risk than fixed rate securities, they are subject to credit, liquidity and default risk and may be subject to legal or contractual restrictions on resale, which could impair their value.
Defiance Israel Fixed Income ETF | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.
Defiance Israel Fixed Income ETF | High-Yield Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock High-Yield Securities Risk. High-yield securities (also known as “junk bonds”) carry a greater degree of risk and are considered speculative by the major credit rating agencies. High-yield securities may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled payments of principal and interest. Changes in the value of high-yield securities are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade securities. High-yield securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. High-yield securities may experience reduced liquidity and sudden and substantial decreases in price.
Defiance Israel Fixed Income ETF | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.
Defiance Israel Fixed Income ETF | Index Provider Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The investment adviser relies upon the Index Provider and its agents to compile, determine, maintain, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders.
Defiance Israel Fixed Income ETF | Limited Operating History Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Limited Operating History Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Defiance Israel Fixed Income ETF | Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Market Risk. The trading prices of debt securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, the Hamas terrorist attacks, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
Defiance Israel Fixed Income ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Code.
Defiance Israel Fixed Income ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell a security held by the Fund due to current or projected underperformance of the security, industry, or sector, unless that security is removed from the Index or the selling of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.
Defiance Israel Fixed Income ETF | Rating Agencies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Rating Agencies Risk. Ratings are not an absolute standard of quality. Ratings are general indicators that reflect only the view of the originating rating agencies from which an explanation of the significance of such ratings may be obtained. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely. Such changes may negatively affect the liquidity or market price of the securities in which the Fund invests. The ratings of securitized assets may not adequately reflect the credit risk of those assets due to their structure.
Defiance Israel Fixed Income ETF | Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Tax Risk. To qualify for the favorable tax treatment generally available to a RIC, the Fund must satisfy, among other requirements described in the SAI, certain diversification requirements. Given the concentration of the Index in a relatively small number of issuers, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could be eligible for relief provisions if the failure is due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. If the Fund were to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, its shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC.
Defiance Israel Fixed Income ETF | Tracking Error Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.
Defiance Israel Fixed Income ETF | Valuation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Valuation Risk. The prices provided by the Fund’s pricing services or independent dealers or the fair value determinations made by the Adviser may be different from the prices used by other investment companies or from the prices at which debt obligations are actually bought and sold. The prices of certain debt obligations provided by pricing services may be subject to frequent and significant change and will vary depending on the information that is available.
