| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Funds performance and the Fund may not achieve its investment objective.
Dividend Yield Risk. While the Fund may hold securities of companies that have historically paid a dividend, those companies may reduce or discontinue their dividends, thus reducing the yield of the Fund. Lower priced securities in the Fund may be more susceptible to these risks. Past dividend payments are not a guarantee of future dividend payments.
Energy Sector Risk. Companies operating in the energy sector may be adversely affected by changes in worldwide energy prices, exploration and production spending. In addition, changes in government regulation, world events and political and economic conditions can affect these companies. These companies also are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism, war and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments, geopolitical conflict and related economic sanctions and labor relations also could affect companies in this sector.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related-activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the US government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). The risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Industry Concentration Risk. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Large Capitalization Company Risk. The Funds investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events and political events may adversely affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid- sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.
Preferred Stock Risk. Typically, a rise in interest rates causes a decline in the value of preferred stocks. Preferred stocks are also subject to credit and default risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payment. Issuers of preferred stocks may redeem their securities prior to maturity at a price below their current market value which would negatively impact the investment return of such preferred stocks.
Real Estate Sector Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.
REIT Risk. The Funds investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.
Sector Risk. The Fund may focus its investments in securities of a particular sector. Economic, legislative or regulatory developments may occur that significantly affect the sector. This may cause the Funds NAV to fluctuate more than that of a fund that does not focus in a particular sector.
Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security in the Funds or an Underlying Funds portfolio.
Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.
Utilities Sector Risk. Companies in the utilities sector are subject to a variety of factors that may adversely affect their business or operations, including high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital in periods of high inflation and unsettled capital markets; governmental regulation of rates the issuer can charge to customers; costs associated with compliance with environmental and other regulations; effects of economic slowdowns and surplus capacity; increased competition; and potential losses resulting from a developing deregulatory environment.

| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Currency Risk. If the Fund invests in securities that trade in, and receive revenues in, foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar. As a result, the Funds investments in foreign currency-denominated securities may reduce the Funds returns.
Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Funds ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets, and more governmental limitations on foreign investment than are more developed markets. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid, and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. The impact of more stringent capital requirements, recent or future regulation of any individual financial company, or recent or future regulation of the financial sector as a whole cannot be predicted.
Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). The risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Industry Concentration Risk. The Fund may concentrate 25% to 35% of its total assets in a particular industry or group of industries to the extent that such industry or group of industries represents 20% or more of the Funds Strategy Benchmark. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Large Capitalization Company Risk. The Funds investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, exchange rates, trading and tariff events and political events may adversely affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid- sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.
Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

| Risk [Text Block] | ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.

| Eventide Large Cap Growth ETF | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Growth Stock Risk. Growth stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Growth stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, growth stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Industry Concentration Risk. The Fund may concentrate 25% to 35% of its total assets in a particular industry or group of industries to the extent that such industry or group of industries represents 20% or more of the Funds Strategy Benchmark. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Large Capitalization Company Risk. The Funds investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events and political events may adversely affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.
Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.
REIT Risk. The Funds investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.
Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than do larger companies. The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.
Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc.

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

Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.

The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.

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

Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Growth Stock Risk. Growth stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Growth stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, growth stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.

| Eventide Large Cap Value ETF | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. The impact of more stringent capital requirements, recent or future regulation of any individual financial company, or recent or future regulation of the financial sector as a whole cannot be predicted.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Industry Concentration Risk. The Fund may concentrate 25% to 35% of its total assets in a particular industry or group of industries to the extent that such industry or group of industries represents 20% or more of the Funds Strategy Benchmark. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Large Capitalization Company Risk. The Funds investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events and political events may adversely affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid- sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.
Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.
REIT Risk. The Funds investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.
Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than do larger companies. The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.
Value Investing Risk. A value style of investing focuses on undervalued companies with characteristics for improved valuations. Value securities are subject to the risk that their valuations never improve or that the returns on value securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Funds investments will vary and at times may be lower than that of other types of investments. Historically, value investments have performed best during periods of economic recovery. Therefore, the value investing style may over time go in and out of favor. Value stocks also may decline in price, even though in theory they are already underpriced.

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

| Risk [Text Block] | Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than do larger companies. The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.

| Risk [Text Block] | Value Investing Risk. A value style of investing focuses on undervalued companies with characteristics for improved valuations. Value securities are subject to the risk that their valuations never improve or that the returns on value securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Funds investments will vary and at times may be lower than that of other types of investments. Historically, value investments have performed best during periods of economic recovery. Therefore, the value investing style may over time go in and out of favor. Value stocks also may decline in price, even though in theory they are already underpriced. |

| Eventide Small Cap ETF | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. The impact of more stringent capital requirements, recent or future regulation of any individual financial company, or recent or future regulation of the financial sector as a whole cannot be predicted.
Healthcare Sector Risk. The healthcare sector may be affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a companys patent may adversely affect that companys profitability. Healthcare companies are subject to competitive forces that may result in price discounting and may be thinly capitalized and susceptible to product obsolescence.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Industry Concentration Risk. The Fund may concentrate 25% to 35% of its total assets in a particular industry or group of industries to the extent that such industry or group of industries represents 20% or more of the Funds Strategy Benchmark. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds Shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events and political events may adversely affect the securities markets.
Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.
REIT Risk. The Funds investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.
Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than do larger companies. The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.
Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.
ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC) and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to the Funds NAV per share and possibly face delisting by NYSE Arca, Inc. (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Funds performance and the Fund may not achieve its investment objective.
Equity Securities Risk. The NAV and market price of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Ethical Investment Risk. The Funds ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.
ETF Structure Risks. The Fund, and any ETFs the Fund may invest in, are structured as ETFs and as a result are subject to special risks, including:
Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). The risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.
Large Capitalization Company Risk. The Funds investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion; and may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Limited History of Operations Risk. The Fund has a limited history of operations for investors to evaluate.
Management Risk. The Advisers reliance on its sector allocation and risk management strategies and related judgments about the value and potential appreciation of securities in which the Fund invests may prove to be incorrect. The Adviser may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events and political events may adversely affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid- sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.
Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.
REIT Risk. The Funds investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities. The liquidity of REITs may change dramatically over time.
Sector Risk. The Fund may focus its investments in securities of a particular sector. Economic, legislative or regulatory developments may occur that significantly affect the sector. This may cause the Funds NAV to fluctuate more than that of a fund that does not focus in a particular sector.
Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security in the Funds or an Underlying Funds portfolio.
Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than do larger companies. The trading volume of securities of smaller-sized companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Smaller-sized companies may have limited markets, product lines or financial resources and may lack management experience.
Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

| Risk [Text Block] | ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.

This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Funds ethical screening guidelines.
To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Advisers values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Advisers corporate engagements and related activities will achieve their intended results. There is a risk that the Advisers activities in this regard could limit the Funds investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Funds investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Advisers activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). The risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

| Risk [Text Block] | Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers. The value of certain types of securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments. Market prices of securities in broad market segments may be adversely affected by a prominent issuer having experienced losses, lack of earnings, failure to meet the markets expectations with respect to new products or services, or even by factors wholly unrelated to the value or condition of the issuer, such as changes in interest rates.

| Strategy Shares Gold Enhanced Yield ETF | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | As with any ETF, there is no guarantee that the Fund will achieve its investment objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value, market price and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, nor is it a complete investment program. The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, market price, total return and value of the Fund and your investment. Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate. Under certain market conditions, the Funds turnover may be very high and considerably higher than that of other funds.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC), and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV, and possibly face delisting by the CBOE BZX Exchange (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.
Cash and Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Funds performance, and the Fund may not achieve its investment objective.
Cash Transactions Risk. ETFs generally are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions partly or entirely in cash, rather than in-kind, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF.
Changing Fixed Income Market Conditions Risk. The future direction of interest rates is uncertain. If interest rates rise, there is risk that rates across the financial system also may rise. Changes in government intervention may have adverse effects on the Funds investments, volatility, and illiquidity in debt markets. Interest rate increases could cause the value of the Fund to decrease. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of a Funds investments and share price to decline. If a Fund invests in derivatives tied to fixed-income markets, the Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives. To the extent a Fund experiences high redemptions because of these policy changes, the Fund may experience increased portfolio turnover, which will increase the costs the Fund incurs and may lower its performance. Furthermore, if rising interest rates cause a Fund to lose enough value, the Fund could also face increased redemptions, which could force the Fund to liquidate investments at disadvantageous times or prices, thereby adversely affecting the Fund. In addition, decreases in fixed income dealer market-making capacity may persist in the future, potentially leading to decreased liquidity and increased volatility in the fixed income markets.
Commodity Risk. Exposure to the commodities markets may subject a fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors, as well as changes in government regulation, such as tariffs, embargoes or burdensome production rules and restrictions. The Commodity Basket Component will invest in energy and industrial metals/precious metals commodities. Please see Energy Sector Risk, Industrial Metals Sector Risk and Precious Metals Sector Risk below.
Commodity Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level, and all distributions from earnings and profits, including any distribution of net tax-exempt income and net long-term capital gains, would be taxable to Fund shareholders as ordinary income. Should the Internal Revenue Service issue further guidance, or Congress enact legislation, that adversely affects the tax treatment of the Subsidiary (which guidance might be applied to the Fund retroactively), it could, among other consequences, limit the Funds ability to pursue its investment strategy.
Counterparty Risk. The Fund may engage in transactions in securities and financial instruments that involve counterparties. Counterparty risk is the risk that a counterparty (the other party to a transaction or an agreement, or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.
Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Funds total return. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuers financial condition changes. The issuer of a fixed income security may also default on its obligations.
Derivatives Risk. The performance of a derivative instrument depends largely on the performance of an underlying instrument, such as a currency, security, rate or index. In addition, the use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may be unwilling or unable to fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Funds returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments, and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Additionally, the Funds obligation to make payments of margin, collateral, or settlement payments to counterparties may heighten liquidity demands on the Funds portfolio. Derivatives may be less tax efficient and subject to changing government regulation that could impact the Funds ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivatives are subject to the risk of adverse market movements and the risk that markets could experience a change in volatility that adversely impacts Fund returns and the Funds obligations and exposures. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to, changing supply and demand relationships; government programs and policies; national and international political and economic events; geopolitical conflicts; changes in interest rates; and inflation and deflation. Derivatives are also subject to operational risk, including potential documentation issues, settlement issues, systems failures, inadequate controls and human error, as well as legal risks arising from insufficient documentation, insufficient capacity or authority of counterparty, or the legality or enforceability of a contract. Derivatives strategies may not be successful, and their successful use will depend on the portfolio managers ability to accurately forecast movements in the market relating to the underlying asset.
Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as rolling. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. Because the margin requirement for futures contracts is less than the value of the assets underlying the futures contract, futures trading involves a degree of leverage. As a result, a relatively small price movement in a futures contract may result in immediate and substantial loss to the Fund, which could significantly adversely affect the Funds performance.
Distribution Policy Risk. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Any capital returned to investors through distributions will be distributed after payment of Fund fees and expenses. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares. For more information, please refer to the section of the Funds prospectus entitled Tax Consequences.
Duration Risk. Longer-term fixed-income securities may be more sensitive to interest rate changes, particularly in periods of rising interest rates. Effective duration estimates price changes for relatively small changes in rates. If rates rise significantly, effective duration may tend to understate the drop in a securitys price. If rates drop significantly, effective duration may tend to overstate the rise in a securitys price.
Energy Sector Risk. The Funds exposure to the energy sector will result in the performance of the Fund being relatively corelated to, and affected by, developments in the energy sector, such as the possibility that government regulation will negatively impact companies in this sector. Energy entities are subject to the risks specific, but not limited, to the following:
ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than a fund that invests directly in individual securities. By investing in other ETFs, the Fund will be subject to the risks associated with the underlying investments of such ETFs. ETFs are also subject to the risks described under ETF Structures Risk.
ETF Structure Risks. The Fund is structured as an ETF and, as a result, is subject to special risks, including:
Fixed Income Securities Risk. The value of the Funds investments in fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the risk that the debtor may default), extension risk (the risk that an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the risk that the debtor may pay its obligation early, thereby reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Funds share price and total return to be reduced and fluctuate more than other types of investments.
Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions, such as exchange controls).
Gold Risk. The price of gold may be affected by several factors, including the global gold supply and demand and investors expectations with respect to the rate of inflation. Developments affecting the value of gold may have a significant impact on the Fund. Gold markets have been, and will likely continue to be, subject to sharp price fluctuations, which may lead to significant price fluctuations in the shares of the Fund. In addition, it is possible that a shareholder may not realize his or her investment objective because the gold markets have historically experienced extended periods of flat or declining prices, in addition to sharp fluctuations. There is no assurance that gold will maintain its long-term value in terms of purchasing power in the future.
Income Risk. The Funds distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences deterioration of the underlying debt securities it holds, or when the Fund realizes a loss upon the sale of a debt security.
Industrial Metals Sector Risk. Risks of investing in the industrial metals sector commodities include, in addition to other risks, substantial price fluctuations over short periods of time, imposition of import controls, increased competition, government regulation, disruptions in mining, storing, and refining of metals, and changes in industrial, governmental and commercial demand for certain metals.
Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. The maturity and effective duration of the Funds investment portfolio may vary materially, from time to time, and there is no assurance that the Fund will achieve or maintain any particular target maturity or effective duration of its investment portfolio.
Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets, asset classes, and/or the overall market.
Issuer Specific Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Funds shares, to decline. The value of a specific security can be more volatile than the market as a whole, and can perform differently from the value of the market as a whole.
Management Risk. The Advisor may not successfully implement the Funds investment strategies and, as a result, the Fund may not meet its investment objective.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds NAV or market price per share may decline suddenly or over a sustained period of time. Overall market risks may also affect the value of the Fund. Factors such as domestic and foreign economic growth rates and market conditions, interest rate levels, trading and tariff events, geopolitical conflicts, interest rate levels, and political events may adversely affect the securities markets.
Non-Diversification Risk. To the extent that the Fund holds securities of a smaller number of issuers, or invests a larger percentage of its assets in a single issuer, than a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers, and to economic, political, market or regulatory events affecting any one of those issuers.
Precious Metals Sector Risk. Prices of precious metals and of precious metal-related securities have historically been volatile. Economic, financial and political factors can cause periods of volatility. Because precious metals and other commodities do not generate investment income, the return on such investments will be derived solely from the appreciation or depreciation of such investments. Changes in the production and sale of precious metals by governments or central banks, or other large holders, can be unpredictable and may also have a significant impact on the prices of precious metals.
Regulatory Risk. Changes in the laws or regulations of the United States, Cayman Islands, or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective, and could increase the operating expenses of the Fund. The Fund and the Subsidiary are commodity pools under the U.S. Commodity Exchange Act (the CEA), and the Advisor is a commodity pool operator registered with and regulated by the CFTC.
Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act of 1933 (the Securities Act). Rule 144A securities are restricted securities that are not publicly traded and may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets, and the market for such securities is typically less active than the market for publicly traded securities. As a result, Rule 144A securities may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund.
U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the full faith and credit of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may not be backed by the full faith and credit of the U.S. government, which could affect the Funds ability to recover should they default.
Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Funds net asset value and market price per share to experience significant increases or declines in value over short periods of time; however, all investments, whether long- or short-term, are subject to risk of loss.
Wholly Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiarys investments in commodity-related instruments. There can be no assurance that the Subsidiarys investments will contribute to the Funds returns. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus, and could adversely affect the Fund, such as by reducing the Funds investment returns.

| Risk [Text Block] | Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC), and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV, and possibly face delisting by the CBOE BZX Exchange (the Exchange). These risks could cause intra-day bid/ask spreads for the Funds shares to widen.

Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions, such as exchange controls).

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

| Strategy Shares Gold Enhanced Yield ETF | Cash Transactions Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Cash Transactions Risk. ETFs generally are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions partly or entirely in cash, rather than in-kind, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Changing Fixed Income Market Conditions Risk. The future direction of interest rates is uncertain. If interest rates rise, there is risk that rates across the financial system also may rise. Changes in government intervention may have adverse effects on the Funds investments, volatility, and illiquidity in debt markets. Interest rate increases could cause the value of the Fund to decrease. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of a Funds investments and share price to decline. If a Fund invests in derivatives tied to fixed-income markets, the Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives. To the extent a Fund experiences high redemptions because of these policy changes, the Fund may experience increased portfolio turnover, which will increase the costs the Fund incurs and may lower its performance. Furthermore, if rising interest rates cause a Fund to lose enough value, the Fund could also face increased redemptions, which could force the Fund to liquidate investments at disadvantageous times or prices, thereby adversely affecting the Fund. In addition, decreases in fixed income dealer market-making capacity may persist in the future, potentially leading to decreased liquidity and increased volatility in the fixed income markets. |

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

There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuers financial condition changes. The issuer of a fixed income security may also default on its obligations.

| Strategy Shares Gold Enhanced Yield ETF | Derivatives Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Derivatives Risk. The performance of a derivative instrument depends largely on the performance of an underlying instrument, such as a currency, security, rate or index. In addition, the use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may be unwilling or unable to fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Funds returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional investments, and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Additionally, the Funds obligation to make payments of margin, collateral, or settlement payments to counterparties may heighten liquidity demands on the Funds portfolio. Derivatives may be less tax efficient and subject to changing government regulation that could impact the Funds ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivatives are subject to the risk of adverse market movements and the risk that markets could experience a change in volatility that adversely impacts Fund returns and the Funds obligations and exposures. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to, changing supply and demand relationships; government programs and policies; national and international political and economic events; geopolitical conflicts; changes in interest rates; and inflation and deflation. Derivatives are also subject to operational risk, including potential documentation issues, settlement issues, systems failures, inadequate controls and human error, as well as legal risks arising from insufficient documentation, insufficient capacity or authority of counterparty, or the legality or enforceability of a contract. Derivatives strategies may not be successful, and their successful use will depend on the portfolio managers ability to accurately forecast movements in the market relating to the underlying asset.
Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as rolling. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. Because the margin requirement for futures contracts is less than the value of the assets underlying the futures contract, futures trading involves a degree of leverage. As a result, a relatively small price movement in a futures contract may result in immediate and substantial loss to the Fund, which could significantly adversely affect the Funds performance.

| Risk [Text Block] | ETF Risk. Like a mutual fund, the value of an ETF can fluctuate based on the prices of the securities owned by the ETF. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than a fund that invests directly in individual securities. By investing in other ETFs, the Fund will be subject to the risks associated with the underlying investments of such ETFs. ETFs are also subject to the risks described under ETF Structures Risk.

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

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

Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Funds net asset value (NAV), market price and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.
The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return, and the value of the Fund and your investment.
You could lose money by investing in the Fund. The Fund is subject to the risks summarized below. Any of these risks could adversely affect the Funds NAV, trading price, yield, total return, or ability to meet its investment objective.
ADR Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. To establish a value for the shares, the issuer establishes a conversion rate equal to one share of an ADR for a certain number of shares of the stock of a foreign company. As a result, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the US Dollar declines, the ADR price would decline by a similar measure. Certain ADRs are not listed on an exchange and therefore may be considered to be illiquid.
Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An Authorized Participant is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (DTC), and that has executed a Participant Agreement with the Funds distributor (Distributor). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting. These risks could cause intraday bid/ask spreads for the Funds shares to widen.
Equity Securities Risk. The price of common stock in the Funds portfolio will fluctuate based on actual or perceived changes in a companys financial condition and on market and economic conditions. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.
ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:
Foreign Securities Risk. Since the Funds investments may include ADRs, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.
Large Capitalization Company Risk. Investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in consumer tastes or innovative smaller competitors, potentially resulting in lower markets for their common stock. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. The investment strategies and models employed by the Sub-Advisor in selecting investments and asset allocations for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having similar investment strategies. In addition, the Sub-Advisors judgment about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect, and there is no guarantee that the Sub-Advisors judgment will produce the desired result. The measures that the Advisor, Sub-Advisor or portfolio manager use to monitor and manage the risks of the Fund may not accomplish the intended results and the Fund may experience losses significantly greater than expected.
Market Risk. The value of securities in the Funds portfolio will fluctuate and, as a result, the Funds share price may decline suddenly or over a sustained period of time. Overall market risks may also affect the value of the Fund. Factors such as economic growth and market conditions, trading and tariff events, geopolitical conflicts, interest rate levels and political events affect the securities markets.
Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies tend to be more volatile than larger companies. These companies may experience higher failure rates than larger companies. Midsized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources, and may lack management experience.
New Fund Risk. The Fund is a relatively new fund with limited history of operations as an ETF for investors to evaluate. If the Fund is unable to achieve an economic size, expenses will be higher than expected and the Fund might close, which could produce adverse tax consequences for shareholders.
Non-Diversification Risk. The Fund is classified as a non-diversified fund under the 1940 Act. Accordingly, the Fund may invest a high percentage of its assets in a limited number of issuers. To the extent that the Fund holds securities of a smaller number of issuers or invests a larger percentage of its assets in a single issuer than would a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers, as well as to economic, political, market or regulatory events affecting any one of those issuers.
Sector Risk. Companies with high market dominance can be susceptible to sector-specific downturns or sudden valuation corrections if regulatory or competitive landscapes shift. Economic, legislative or regulatory developments may occur that significantly affect the sector. This may cause the Funds NAV to fluctuate more than that of a fund that does not focus in a particular sector.
The Fund is subject to the following specific sector risks:
Information Technology Sector Risk. Information technology companies face intense competition and may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence. Companies in the information technology sector are heavily dependent on patent and intellectual property rights.

| Risk [Text Block] | ADR Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. To establish a value for the shares, the issuer establishes a conversion rate equal to one share of an ADR for a certain number of shares of the stock of a foreign company. As a result, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the US Dollar declines, the ADR price would decline by a similar measure. Certain ADRs are not listed on an exchange and therefore may be considered to be illiquid. |
