Investment Risks |
Nov. 30, 2025 |
|---|---|
| Bancreek U.S. Large Cap ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. |
| Bancreek U.S. Large Cap ETF | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. |
| Bancreek U.S. Large Cap ETF | Common Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests. |
| Bancreek U.S. Large Cap ETF | Convertible Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk. A convertible security has characteristics of both equity and debt securities and, as a result, is exposed to risks that are typically associated with both types of securities. The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security tends to perform more like a stock when the underlying stock price is high relative to the conversion price and more like a debt security when the underlying stock price is low relative to the conversion price. |
| Bancreek U.S. Large Cap ETF | Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. The Fund is susceptible to operational risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cybersecurity breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cybersecurity breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cybersecurity breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cybersecurity, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cybersecurity systems of issuers or third-party service providers. |
| Bancreek U.S. Large Cap ETF | Early Close/Trading Halt Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. |
| Bancreek U.S. Large Cap ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. The prices of equity securities in which the Fund invests may rise and fall daily. These price movements may result from factors affecting individual issuers, industries or the stock market as a whole. |
| Bancreek U.S. Large Cap ETF | Issuer-Specific Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Risk. Fund performance depends on the performance of the issuers to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund. |
| Bancreek U.S. Large Cap ETF | Large-Capitalization Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies or the market as a whole. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. |
| Bancreek U.S. Large Cap ETF | Limited Authorized Participants, Market Makers and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occurs, the risk of which is higher during periods of market stress, shares of the Fund may trade at a material discount to NAV, possibly face delisting, and may experience wider bid-ask spreads: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Bancreek U.S. Large Cap ETF | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Sub-Adviser’s success or failure to implement investment strategies for the Fund. The Fund’s principal investment strategies are dependent upon the use of the Sub-Adviser’s proprietary security selection process and, as a result, the Sub-Adviser’s skill in understanding and utilizing such processes. The achievement of the investment objective of the Fund cannot be guaranteed and the Sub-Adviser’s management of the Fund may not produce the intended results. |
| Bancreek U.S. Large Cap ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market price of an investment could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of an investment also may decline because of factors that affect a particular industry or industries such as labor shortages, increased production costs, and competitive conditions. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, the imposition of tariffs, or other events could have a significant impact on the market generally and on specific investments. For example, in recent years, the COVID-19 pandemic, the large expansion of government deficits and debt as a result of government actions to mitigate the effects of the pandemic, Russia’s invasion of Ukraine, and the rise of inflation have resulted in extreme volatility in the global economy and in global financial markets. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected. |
| Bancreek U.S. Large Cap ETF | Model and Data Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Model and Data Risk. The Fund relies heavily on proprietary quantitative investment selection models as well as data and information supplied by third parties that are utilized by such models. To the extent the models do not perform as designed or as intended, the Fund’s strategy may not be successfully implemented and the Fund may lose value. If the models or data are incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities that would have been excluded or included had the models or data been correct and complete. |
| Bancreek U.S. Large Cap ETF | Smaller Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Smaller Fund Risk. A smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size, in which case it could ultimately liquidate. The Fund may be liquidated by the Board of Trustees (the “Board”) without a shareholder vote. In a liquidation, shareholders of the Fund will receive an amount equal to the Fund’s NAV, after deducting the costs of liquidation, including the transaction costs of disposing of the Fund’s portfolio investments. Receipt of a liquidation distribution may have negative tax consequences for shareholders. Additionally, during the Fund’s liquidation all or a portion of the Fund’s portfolio may be invested in a manner not consistent with its investment objective and investment policies. |
| Bancreek U.S. Large Cap ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund. |
| Bancreek U.S. Large Cap ETF | Portfolio Turnover Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk. The Fund’s investment strategy may result in relatively high portfolio turnover, which may result in increased transaction costs and may lower Fund performance. |
| Bancreek U.S. Large Cap ETF | Preferred Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk. Preferred stock is subordinated to bonds and other debt instruments in a company’s capital structure and, therefore, will be subject to greater credit risk than those debt instruments. In addition, preferred stock is subject to other risks such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having limited liquidity, changing tax treatments, and possibly being in heavily regulated industries. |
| Bancreek U.S. Large Cap ETF | Sector Focus Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk. While the Fund’s sector exposure is expected to vary over time, the Fund may invest a significant portion of its assets in one or more sectors from time to time. When the Fund has significant exposure to a particular sector, it will be more susceptible to the risks affecting that sector. As of March 3, 2026, the Technology Sector represented a significant portion of the Fund.
Technology Sector Risk. Companies in the technology sector, as traditionally defined, including information technology companies, may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the technology sector may face increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. |
| Bancreek U.S. Large Cap ETF | Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Risk. Shares of the Fund may trade on the NYSE Arca, Inc. (the “Exchange”) above (premium) or below (discount) their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask), which is known as the bid-ask spread. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. In such a circumstance, the Fund’s shares could trade at a premium or discount to their NAV. |
| Bancreek International Large Cap ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. |
| Bancreek International Large Cap ETF | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. |
| Bancreek International Large Cap ETF | Common Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests. |
| Bancreek International Large Cap ETF | Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk. Investments directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. |
| Bancreek International Large Cap ETF | Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. The Fund is susceptible to operational risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cybersecurity breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cybersecurity breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cybersecurity breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cybersecurity, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cybersecurity systems of issuers or third-party service providers. |
| Bancreek International Large Cap ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price. |
| Bancreek International Large Cap ETF | Depositary Receipts Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to Foreign Investment Risks. Sponsored and unsponsored depositary receipts involve risk not experienced when investing directly in the equity securities of an issuer. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts. |
| Bancreek International Large Cap ETF | Early Close/Trading Halt Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. |
| Bancreek International Large Cap ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. The prices of equity securities in which the Fund invests may rise and fall daily. These price movements may result from factors affecting individual issuers, industries or the stock market as a whole. |
| Bancreek International Large Cap ETF | Foreign Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including due to: differences in information available about foreign issuers; differences in investor protection standards in other jurisdictions; capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; political, diplomatic and economic risks; regulatory risks; and foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns. |
| Bancreek International Large Cap ETF | Foreign Securities Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Valuation Risk. The Fund’s value may be impacted by events that cause the fair value of foreign securities to materially change between the close of the local exchange on which they trade and the time at which the Fund prices its shares. Additionally, because foreign exchanges on which securities held by the Fund may be open on days when the Fund does not price its shares, the potential exists for the value of the securities in the Fund’s portfolio to change on days when shareholders will not be able to purchase or sell shares. |
| Bancreek International Large Cap ETF | Forward Foreign Currency Contracts Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Forward Foreign Currency Contracts Risk. To the extent the Fund utilizes forward foreign currency contracts, the Fund will contract with a foreign or domestic bank, or a foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. Forward foreign currency contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged. Forward foreign currency contracts may limit any potential gain that might result should the value of the underlying currencies increase. In addition, because forward currency exchange contracts are privately negotiated transactions, there can be no assurance that the Fund will have flexibility to roll-over a forward foreign currency contract upon its expiration if it desires to do so. |
| Bancreek International Large Cap ETF | Geographic Region Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Region Risk. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or a particular country, the Fund will generally have more exposure to that region or country’s economic risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a significant portion of the Fund’s assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund’s investments. Adverse conditions in a certain region or country can also adversely affect securities of issuers in other countries whose economies appear to be unrelated.
Risk of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in other regions. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, piracy of intellectual property, data and other security breaches (especially of data stored electronically), political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest. Certain Asian economies have experienced rapid rates of economic growth and industrialization in recent years, and there is no assurance that these rates of economic growth and industrialization will be maintained. Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Certain Asian countries have also developed increasingly strained relationships with the United States, and if these relations were to worsen, they could adversely affect Asian issuers that rely on the United States for trade. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.
Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region. Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.
Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. China is a key trading partner of many Asian countries and any changes in trading relationships between China and other Asian countries may affect the region as a whole. Adverse economic conditions or developments in neighboring countries may increase investors’ perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.
Risk of Investing in Europe. Most developed countries in Western Europe are members of the European Union (“EU”), and many are also members of the European Monetary Union (“EMU”), which requires compliance with restrictions on inflation rates, deficits and debt levels. Unemployment in certain European nations is high and several countries face significant debt problems. These conditions can significantly affect every country in Europe. The euro is the official currency of most of the EU countries and, accordingly, the Fund’s investment in European securities may lead to significant exposure to the euro and events affecting it. A significant decline in the value of the euro, or the exit of a country from the EU or EMU, may produce unpredictable effects on trade and commerce generally and could lead to increased volatility in financial markets worldwide. Political or economic disruptions in European countries, even in countries in which the Fund is not invested, and the stability of the EU membership may adversely affect security values and thus the Fund’s holdings. In addition, the extent and duration of Russia’s military invasion of Ukraine and the broad-ranging economic sanctions levied against Russia by the United States, the EU, the United Kingdom, and other countries, are impossible to predict, but these events could have a significant adverse impact on Europe’s overall economy and may adversely affect the Fund’s performance. Risk of Investing in Canada. The Canadian economy is heavily dependent on the demand for natural resources and agricultural products. Canada is a major producer of commodities such as forest products, metals, agricultural products, and energy related products like oil, gas, and hydroelectricity. Accordingly, a change in the supply and demand of these resources, both domestically and internationally, can have a significant effect on Canadian market performance. Canada is a top producer of zinc and uranium and a global source of many other natural resources, such as gold, nickel, aluminum, and lead. Conditions that weaken demand for such products worldwide could have a negative impact on the Canadian economy as a whole. Changes to the U.S. economy, including the imposition of tariffs by the U.S., may significantly affect the Canadian economy because the United States is Canada’s largest trading partner and foreign investor. These and other factors could have a negative impact on the Fund and its investments in Canada. |
| Bancreek International Large Cap ETF | Issuer-Specific Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Risk. Fund performance depends on the performance of the issuers to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund. |
| Bancreek International Large Cap ETF | Large-Capitalization Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies or the market as a whole. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. |
| Bancreek International Large Cap ETF | Limited Authorized Participants, Market Makers and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occurs, the risk of which is higher during periods of market stress, shares of the Fund may trade at a material discount to NAV, possibly face delisting, and may experience wider bid-ask spreads: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Bancreek International Large Cap ETF | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Sub-Adviser’s success or failure to implement investment strategies for the Fund. The Fund’s principal investment strategies are dependent upon the use of the Sub-Adviser’s proprietary security selection process and, as a result, the Sub-Adviser’s skill in understanding and utilizing such processes. The achievement of the investment objective of the Fund cannot be guaranteed and the Sub-Adviser’s management of the Fund may not produce the intended results. |
| Bancreek International Large Cap ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market price of an investment could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of an investment also may decline because of factors that affect a particular industry or industries such as labor shortages, increased production costs, and competitive conditions. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, the imposition of tariffs, or other events could have a significant impact on the market generally and on specific investments. For example, in recent years, the COVID-19 pandemic, the large expansion of government deficits and debt as a result of government actions to mitigate the effects of the pandemic, Russia’s invasion of Ukraine, and the rise of inflation have resulted in extreme volatility in the global economy and in global financial markets. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected. |
| Bancreek International Large Cap ETF | Model and Data Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Model and Data Risk. The Fund relies heavily on proprietary quantitative investment selection models as well as data and information supplied by third parties that are utilized by such models. To the extent the models do not perform as designed or as intended, the Fund’s strategy may not be successfully implemented and the Fund may lose value. If the models or data are incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities that would have been excluded or included had the models or data been correct and complete. |
| Bancreek International Large Cap ETF | Smaller Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Smaller Fund Risk. A smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size, in which case it could ultimately liquidate. The Fund may be liquidated by the Board of Trustees (the “Board”) without a shareholder vote. In a liquidation, shareholders of the Fund will receive an amount equal to the Fund’s NAV, after deducting the costs of liquidation, including the transaction costs of disposing of the Fund’s portfolio investments. Receipt of a liquidation distribution may have negative tax consequences for shareholders. Additionally, during the Fund’s liquidation all or a portion of the Fund’s portfolio may be invested in a manner not consistent with its investment objective and investment policies. |
| Bancreek International Large Cap ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund. The Fund is also susceptible to operational risks through breaches in cyber security. |
| Bancreek International Large Cap ETF | Portfolio Turnover Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk. The Fund’s investment strategy may result in relatively high portfolio turnover, which may result in increased transaction costs and may lower Fund performance. |
| Bancreek International Large Cap ETF | Sector Focus Risk [Member] | |

| Risk [Text Block] | Sector Focus Risk. While the Fund’s sector exposure is expected to vary over time, the Fund may invest a significant portion of its assets in one or more sectors from time to time. When the Fund has significant exposure to a particular sector, it will be more susceptible to the risks affecting that sector. |
| Bancreek International Large Cap ETF | Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Risk. Shares of the Fund may trade on the NYSE Arca, Inc. (the “Exchange”) above (premium) or below (discount) their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask), which is known as the bid-ask spread. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. In such a circumstance, the Fund’s shares could trade at a premium or discount to their NAV. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Anti-Takeover Provision Risk. Investors in closed-end funds are subject to the risk that the organizational documents of a closed-end fund may include provisions that could limit the ability of other entities or persons to acquire control of the closed-end fund or to change the composition of its board, which could limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the closed-end fund. |
| Saba Closed-End Funds ETF | Cash Transactions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transactions Risk. To the extent the Fund effects part or all of its creations and redemptions for cash rather than in-kind securities, the Fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV. |
| Saba Closed-End Funds ETF | Climate Change-Related Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Climate Change-Related Risks. The environmental effects of climate change, including rising temperatures, extreme weather, fires, flooding, erratic weather fluctuations, agricultural failures and displacement and destabilization of human populations, could have materially adverse effects on the Underlying Funds held by the Fund. In addition to the physical, economic and geo-political risks associated with climate change, there are transition risks. The willingness of certain governments, industries and businesses, especially those that profit from, or have a reliance on, fossil fuels, to adapt to climate change or transition to sustainable practices may also adversely affect the Underlying Funds. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain industries whose activities or products are seen as accelerating climate change, or ill-positioned in light of the economic and social demands imposed by climate change. In recent years, certain investors have incorporated the business risks of climate change and the adequacy of companies’ responses to climate change as part of their investment theses. These shifts in investing priorities may result in adverse effects on the trading price of securities if investors determine that the company has not made sufficient progress on climate change and environmental sustainability matters whether or not climate change proves to be as severe as predicted or preventable. The values of securities whose performance is linked to assets and revenue streams that are exposed to climate change risk may readily be affected by both long-term, systemic effects of climate change, as well as severe environmental events whose occurrence is inherently unpredictable. |
| Saba Closed-End Funds ETF | Passive Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk. Convertible securities are bonds, debentures, notes, preferred securities or other securities that may be converted or exchanged (by the holder or the issuer) into shares of the underlying common stock (or cash or securities of equivalent value), either at a stated price or stated rate. Convertible securities have characteristics similar to both fixed income and equity securities. Convertible securities generally are subordinated to other similar but non-convertible securities of the same issuer, although convertible bonds, as corporate debt obligations, enjoy seniority in right of payment to all equity securities, and convertible preferred stock is senior to common stock, of the same issuer. Because of the subordination feature, however, convertible securities typically are considered to be lower quality than similar non-convertible securities. |
| Saba Closed-End Funds ETF | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. To the extent that the Fund or an Underlying Fund engages in derivative transactions, it will be subject to credit risk with respect to the counterparties. The Fund or the Underlying Fund may obtain only a limited or no recovery or may experience significant delays in obtaining recovery under derivative contracts if a counterparty experiences financial difficulties and becomes bankrupt or otherwise fails to perform its obligations under a derivative contract. |
| Saba Closed-End Funds ETF | Credit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk. Issuers or guarantors of debt instruments or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities may be unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is the chance that any of an Underlying Fund’s portfolio holdings will have its credit ratings downgraded or will default (fail to make scheduled interest or principal payments), potentially reducing the Underlying Fund’s income level and share price. |
| Saba Closed-End Funds ETF | Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk. The Fund or an Underlying Fund may invest in non-U.S. dollar denominated securities of foreign issuers. Where a fund’s NAV is determined in U.S. dollars and the fund invests in non-U.S. dollar denominated securities, the fund’s NAV could decline if the currency of the non-U.S. market in which the fund invests depreciates against the U.S. dollar, even if the value of the fund’s holdings, measured in the foreign currency, increases. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation and political developments. |
| Saba Closed-End Funds ETF | Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. The Fund is susceptible to operational risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cybersecurity breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cybersecurity breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cybersecurity breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cybersecurity, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cybersecurity systems of issuers or third-party service providers. |
| Saba Closed-End Funds ETF | Deflation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Deflation Risk. Prices throughout the economy may decline over time, which may have an adverse effect on the market valuation of companies, their assets and revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of an Underlying Fund’s portfolio. |
| Saba Closed-End Funds ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. A derivative instrument often has risks similar to its underlying instrument and may have additional risks, including imperfect correlation between the value of the derivative and the underlying instrument, risks of default by the counterparty to certain derivative transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative relates, and risks that the derivative instruments may not be liquid. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index. Gains or losses in a derivative may be magnified and may be much greater than the derivative’s original cost.
Covered Call Option Writing Risk. The Fund may invest in Underlying Funds that engage in a strategy known as “covered call option writing,” which is designed to produce income from option premiums and offset a portion of a market decline in the underlying security. The writer (seller) of a covered call option forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call but has retained the risk of loss should the price of the underlying security decline. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price.
Futures Contracts Risk. Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying securities. In addition, there is the risk that the purchaser of a futures contract may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by a fund or its investment adviser, thus limiting the ability to implement the fund’s strategies. Futures markets are highly volatile, and the use of futures may increase the volatility of a fund’s NAV. Futures are also subject to leverage risks and to liquidity risk. Options Risk. Options give the holder of the option the right to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. They are subject to correlation risk because there may be an imperfect correlation between the options and the securities markets that cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Sub-Adviser’s ability to correctly predict future price fluctuations and the degree of correlation between the options and securities markets. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Sub-Adviser, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.
Options on Swaps. An option on a swap agreement, or a “swaption,” is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. In return, the purchaser pays a “premium” to the seller of the contract. The seller of the contract receives the premium and bears the risk of unfavorable changes on the underlying swap. The Fund may write (sell) and purchase put and call swaptions. The Fund may also enter into swaptions on either an asset-based or liability-based basis, depending on whether the Fund is hedging its assets or its liabilities. The Fund may write (sell) and purchase put and call swaptions to the same extent it may make use of standard options on securities or other instruments. Swaptions are generally subject to the same risks involved in the Fund’s use of options.
Swap Agreement Risk. Swap agreements are generally traded in over-the-counter (“OTC”) markets and have only recently become subject to regulation by the U.S. Commodity Futures Trading Commission (“CFTC”). CFTC rules, however, do not cover all types of swap agreements. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act in connection with the Fund’s swap agreements. The lack of regulation in these markets could expose investors to significant losses under certain circumstances, including in the event of trading abuses or financial failure by participants.
Total Return Swap Risk. A total return swap is a contract in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities, or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to a fund’s portfolio because, in addition to its total net assets, the fund would be subject to investment exposure on the notional amount of the swap. The primary risks associated with total returns swaps are credit risks (if the counterparty fails to meet its obligations) and market risk (if there is no liquid market for the agreement or unfavorable changes occur to the underlying asset). |
| Saba Closed-End Funds ETF | Dividend Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Dividend Risk. An issuer of a security may be unwilling or unable to pay income on a security. Common stocks do not assure dividend payments. Common stockholders have a right to receive dividends only after the company has provided for payment of its creditors, bondholders and preferred stockholders. Dividends are paid only when declared by an issuer’s board of directors, and the amount of any dividend may vary over time. |
| Saba Closed-End Funds ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Common stock holds the lowest priority in the capital structure of a company, and therefore takes the largest share of the company’s risk and its accompanying volatility. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock. Also, prices of common stocks are sensitive to general market movements. |
| Saba Closed-End Funds ETF | Foreign and Emerging Markets Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign and Emerging Markets Securities Risk. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign and emerging market securities. Foreign and emerging market securities may have relatively low market liquidity, decreased publicly available information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Differences in regulatory, accounting, auditing, and financial reporting and recordkeeping standards could impede the Sub-Adviser’s ability to evaluate local companies and impact the Fund’s performance. Foreign and emerging market securities may be subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign and emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets may be subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than more developed markets. In addition, securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets.
The Fund or an Underlying Fund’s investment in securities of foreign companies may be in the form of depositary receipts or other securities convertible into securities of foreign issuers. Depositary receipts generally must be sponsored but may be unsponsored. Sponsored depositary receipts are established jointly by a depositary and the underlying issuer, whereas unsponsored depositary receipts may be established by a depositary without participation by the underlying issuer. Holders of an unsponsored depositary receipt generally bear all the costs associated with establishing the unsponsored depositary receipt. In addition, the issuers of the securities underlying unsponsored depositary receipts are not obligated to disclose material information in the United States and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts. The regulatory framework pursuant to which foreign closed-end funds operate may not provide the same protections afforded by U.S. federal securities laws. In addition, where all or a portion of an ETF’s portfolio holdings trade in markets that are closed when the market for the ETF is open, there may be valuation differences that could lead to differences between the ETF’s market price and the value of the ETF’s portfolio holdings. |
| Saba Closed-End Funds ETF | Fund Distributions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fund Distributions Risk. The Fund seeks to make cash distributions once per month throughout a calendar year based on a rate determined at the beginning of the year. Because these distributions will be made from Fund assets and shareholders are generally not expected to reinvest such distributions in additional Fund shares, the Fund’s monthly cash distributions will reduce the amount of assets available for investment by the Fund. It is possible for the Fund to suffer substantial investment losses and simultaneously experience additional asset reductions as a result of its distributions to shareholders under this distribution policy. Moreover, even if the Fund’s capital grows over short, intermediate, or long periods of time, it is possible that such growth will be insufficient to enable the Fund to maintain the amount of its cash distributions without returning capital to shareholders. A return of capital is a return of all or part of a shareholder’s original investment in the Fund. In general, a return of capital is not immediately taxable to a shareholder. Rather, it reduces a shareholder’s cost basis in Fund shares and is not taxable to a shareholder until his or her cost basis has been reduced to zero. The rate and dollar amount of the Fund’s monthly income payments could vary substantially from one year to the next, during the course of a year, and over time depending on several factors, including the performance of the financial markets in which the Fund invests, the allocation of Fund assets across different asset classes and investments, the performance of the Fund’s investment strategies, and the amount and timing of prior distributions by the Fund. The Fund is not guaranteed to provide a fixed or stable level of cash distributions at any time or over any period of time. |
| Saba Closed-End Funds ETF | Fund of Funds Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fund of Funds Risk. Because the Fund is a “fund of funds,” its investment performance largely depends on the investment performance of the Underlying Funds in which it invests. An investment in the Fund is subject to the risks associated with the Underlying Funds. The Fund will pay indirectly a proportional share of the fees and expenses of the Underlying Funds in which it invests (referred to herein as “acquired fund fees and expenses”), including their investment advisory and administration fees, in addition to its own fees and expenses. In addition, at times, certain segments of the market represented by constituent Underlying Funds may be out of favor and underperform other segments. |
| Saba Closed-End Funds ETF | Geographic Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. |
| Saba Closed-End Funds ETF | High Yield or Non-Investment Grade Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Yield or Non-Investment Grade Securities Risk. High yield or non-investment grade securities (commonly referred to as “junk bonds”) and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations and are generally considered to be speculative. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, an Underlying Fund may incur additional expenses to seek recovery. |
| Saba Closed-End Funds ETF | Illiquid Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Illiquid Securities Risk. Closed-end funds are not limited in their ability to invest in illiquid securities. Securities with reduced liquidity involve greater risk than securities with more liquid markets. Market quotations for securities not traded on national exchanges may vary over time, and if the credit quality of a fixed-income security unexpectedly declines, secondary trading of that security may decline for a period of time. In the event that an Underlying Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. |
| Saba Closed-End Funds ETF | Inflation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inflation Risk. The value of assets or income from an investment will be worth less in the future as inflation decreases the value of money. |
| Saba Closed-End Funds ETF | Inflation-Protected Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inflation-Protected Securities Risk. Inflation-protected debt securities may react differently from other types of debt securities and tend to react to changes in “real” interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation. Also, the inflation index utilized by a particular inflation-protected security may not accurately reflect the true rate of inflation, in which case the market value of the security could be adversely affected. |
| Saba Closed-End Funds ETF | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk. Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of shares of an Underlying Fund and its holdings to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations. The Fund may seek to hedge interest rate risk through the use of short positions in U.S. Treasury securities or in ETFs that seek to track the performance of bond indices, or through the use of derivative instruments, but there can be no guarantee that such strategies will be successful. |
| Saba Closed-End Funds ETF | Issuer-Specific Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Risk. The value of an Underlying Fund may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. |
| Saba Closed-End Funds ETF | Leverage Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk. Leverage may result from ordinary borrowings or may be inherent in the structure of certain of the Fund’s investments such as derivatives. If the prices of those investments decrease, or if the cost of borrowing exceeds any increase in the prices of those investments, the NAV of the Fund’s shares will decrease faster than if the Fund had not used leverage. To repay borrowings, the Fund may have to sell investments at a time and at a price that is unfavorable to the Fund. Interest on borrowings is an expense the Fund would not otherwise incur, and the Fund’s expenses will vary depending on the extent to which the Fund uses leverage. Leverage magnifies the potential for gain and the risk of loss. If the Fund uses leverage, there can be no assurance that the Fund’s leverage strategy will be successful. The Underlying Funds in which the Fund may invest may be leveraged. As a result, the Fund may be exposed indirectly to leverage through investment in the Underlying Funds. An investment in securities of Underlying Funds that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the shares) will be diminished. |
| Saba Closed-End Funds ETF | Limited Authorized Participants, Market Makers and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occurs, the risk of which is higher during periods of market stress, the Fund’s shares may trade at a material discount to NAV and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Saba Closed-End Funds ETF | Loans Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Loans Risk. Loans are subject to the credit risk of nonpayment of principal or interest. Economic downturns or increases in interest rates may cause an increase in defaults, interest rate risk and liquidity risk. Loans may or may not be collateralized at the time of acquisition, and any collateral may be relatively illiquid or lose all or substantially all of its value subsequent to investment. In the event of bankruptcy of a borrower, an Underlying Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a loan. Junior loans, which have a lower place in the borrower’s capital structure than senior loans and may be unsecured, involve a higher degree of overall risk than senior loans of the same borrower. An Underlying Fund's investments in loans are also subject to prepayment or call risk. Loans may have settlement periods in excess of seven days. Failure to receive sales proceeds on a timely basis may constrain an Underlying Fund's ability to meet its obligations (including obligations to redeeming shareholders). |
| Saba Closed-End Funds ETF | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is an actively managed ETF. While the Fund’s investment program was designed with a view to achieving the Fund’s investment objective, there can be no assurance or guarantee that the Fund will achieve its stated investment objective over short- or long-term market cycles. The Sub-Adviser’s proprietary screening and selection process of the Underlying Funds and the Underlying Fund Managers and its use of investment strategies, including the use of borrowing and derivatives, may not produce the intended results. |
| Saba Closed-End Funds ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market price of a security or instrument could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, the imposition of tariffs, or other events could have a significant impact on the market generally and on specific securities. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. |
| Saba Closed-End Funds ETF | Mortgage-Backed and Asset-Backed Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage-Backed and Asset-Backed Securities Risk. Investments in mortgage- and asset-backed securities are subject to prepayment or call risk, which is the risk that payments from the borrower may be received earlier than expected due to changes in the rate at which the underlying loans are prepaid. Securities may be prepaid at a price less than the original purchase value. |
| Saba Closed-End Funds ETF | Municipal Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Municipal Securities Risk. Municipal securities are debt obligations issued by states or by political subdivisions or authorities of states. Municipal securities are typically designated as general obligation bonds, which are general obligations of a governmental entity that are backed by the taxing power of such entity, or revenue bonds, which are payable from the income of a specific project or authority and are not supported by the issuer’s power to levy taxes. Lower-quality revenue bonds and other credit-sensitive municipal securities carry higher risks of default than general obligation bonds. Litigation, legislation or other political events, local business or economic conditions or the bankruptcy of the issuer could have a significant effect on the ability of an issuer of municipal securities to make payments of principal and/or interest. Political changes and uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders can significantly affect municipal securities. Because many municipal securities are issued to finance similar projects, especially those related to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market. In addition, changes in the financial condition of an individual municipal issuer can affect the overall municipal market. If the Internal Revenue Service (the “IRS”) determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could significantly decline in value. |
| Saba Closed-End Funds ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund. |
| Saba Closed-End Funds ETF | Preferred Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Securities Risk. Preferred securities are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having limited liquidity, changing tax treatments and possibly being in heavily regulated industries. |
| Saba Closed-End Funds ETF | Real Estate Investment Trust ( [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Real Estate Investment Trust (“REIT”) Risk. Adverse economic, business or political developments affecting real estate could have a major effect on the value of an Underlying Fund’s investments in REITs. Investing in REITs may subject an Underlying Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent and fluctuations in rental income. In addition, REITs are subject to the possibility of failing to qualify for the favorable U.S. federal income tax treatment generally available to them under the Internal Revenue Code of 1986 (the “Internal Revenue Code”) and failing to maintain exemption from the registration requirements of the Investment Company Act of 1940 (the “1940 Act”). “Qualified REIT dividends” (i.e., ordinary REIT dividends other than capital gain dividends and portions of REIT dividends designated as qualified dividend income eligible for capital gain tax rates) are eligible for a 20% deduction by non-corporate taxpayers. Distributions by the Fund to its shareholders that are attributable to qualified REIT dividends received by the Fund and which the Fund properly reports as “section 199A dividends,” are treated as “qualified REIT dividends” in the hands of non-corporate shareholders. A section 199A dividend is treated as a qualified REIT dividend only if the shareholder receiving such dividend holds the dividend-paying regulated investment company (“RIC”) shares for at least 46 days of the 91-day period beginning 45 days before the date on which the shares become ex-dividend and is not under an obligation to make related payments with respect to a position in substantially similar or related property. The Fund is permitted to report such part of its dividends as section 199A dividends as are eligible but is not required to do so. |

| Risk [Text Block] | Risk of Obtaining Non-Public Information. The Sub-Adviser may come into possession of material, non-public information about an Underlying Fund. In these circumstances and until such information becomes publicly available, the Fund may be prevented from transacting in Underlying Fund shares, which may adversely affect the Fund’s performance. |
| Saba Closed-End Funds ETF | Risk of Underlying Fund Market Price Discount from/Premium to Net Asset Value [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Underlying Fund Market Price Discount from/Premium to Net Asset Value. The shares of the Underlying Funds may trade at a discount or premium to their NAV. Historically, shares of Underlying Funds have frequently traded at a discount to their NAV, which discounts have, on occasion, been substantial and lasted for sustained periods of time. This characteristic is a risk separate and distinct from the risk that an Underlying Fund’s NAV could decrease as a result of investment activities. Whether an investor, such as the Fund, will realize gains or losses upon the sale of shares will depend not on the Underlying Funds’ NAVs, but entirely upon whether the market price of the Underlying Funds’ shares at the time of sale is above or below such investor’s purchase price for shares. |
| Saba Closed-End Funds ETF | Selection of Brokers [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Selection of Brokers. The Sub-Adviser may be subject to conflicts of interest relating to its selection of brokers on behalf of the Fund. Transactions for the Fund will be allocated to brokers on the basis of, among other things, best execution and in consideration of a broker’s ability to effect the transactions, its facilities, reliability and financial responsibility, as well as the provision or payment by the broker of the costs of research and research-related services. In addition, brokers may provide other services that are beneficial to the Sub-Adviser, but not necessarily beneficial to the Fund, including, without limitation, capital introduction, marketing assistance, consulting with respect to technology, operations or equipment, and other services or items. Such services and items may influence the Sub-Adviser’s selection of brokers. |
| Saba Closed-End Funds ETF | Short Selling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Short Selling Risk. Short selling involves selling securities, which may or may not be owned, and borrowing the same securities for delivery to the purchaser, with an obligation to replace the borrowed securities at a later date. Short selling allows an investor to seek profits from declines in the prices of securities. A short sale creates the risk of a theoretically unlimited loss because the price of the underlying security could theoretically increase without limit and increase the cost of buying those securities to close the short position. There can be no assurance that the securities necessary to close a short position will be available for purchase. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. Short strategies can also be implemented synthetically through various instruments and be used with respect to indices or in the over-the-counter market and with respect to futures and other instruments. There can be no assurance that such market makers will be willing to make such quotes. Short strategies can also be implemented on a leveraged basis. Lastly, even though an Underlying Fund generally secure a "good borrow" of the security sold short at the time of execution, the lending institution may recall the lent security at any time, thereby forcing such Underlying Fund to purchase the security at the then-prevailing market price, which may be higher. |
| Saba Closed-End Funds ETF | Structured Instruments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Structured Instruments Risk. The Underlying Funds may invest in, or have exposure to, various types of structured instruments, including securities that have demand, tender or put features, or interest rate reset features. Structured instruments are a type of derivative instrument, and the payment and credit qualities of these instruments derive from the assets embedded in the structure from which they are issued. Structured instruments may behave in ways not anticipated by the Underlying Funds, or they may not receive tax, accounting or regulatory treatment anticipated by the Underlying Funds. |
| Saba Closed-End Funds ETF | Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Risk. Shares of the Fund may trade on Cboe BZX Exchange, Inc. (the “Exchange”) above (premium) or below (discount) their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask), which is known as the bid-ask spread. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. In such a circumstance, the Fund’s shares could trade at a premium or discount to their NAV. |

| PLUS Korea Defense Industry Index ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | The Fund is non-diversified under the 1940 Act, meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance. |
| PLUS Korea Defense Industry Index ETF | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount (the difference between the market price of the Fund’s shares and the Fund’s net asset value) and possibly face delisting and the bid/ask spread (the difference between the price that someone is willing to pay for shares of the Fund at a specific point in time versus the price at which someone is willing to sell) on the Fund’s shares may widen. |
| PLUS Korea Defense Industry Index ETF | Cash Transactions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transactions Risk. The Fund may effect all or a portion of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a 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 only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares entirely in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind. The Fund’s use of cash for creations and redemptions could also result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. |

| PLUS Korea Defense Industry Index ETF | Current Market Conditions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Current Market Conditions Risk. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. The COVID-19 global pandemic, or any future public health crisis, and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As this global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets. |
| PLUS Korea Defense Industry Index ETF | Custody Risk [Member] | |

| Risk [Text Block] | Custody Risk. Less developed securities markets, such as South Korea, are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories. |
| PLUS Korea Defense Industry Index ETF | Passive Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Passive Investment Risk. The Fund is not actively managed. The Fund invests in securities included in or representative of the Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. In the event that the Index is no longer calculated, the Index license is terminated or the identity or character of the Index is materially changed, the Fund will seek to engage a replacement index. The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated. To the extent that the Fund invests a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. |
| PLUS Korea Defense Industry Index ETF | Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers. |
| PLUS Korea Defense Industry Index ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. |
| PLUS Korea Defense Industry Index ETF | Defense Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Defense Companies Risk. Defense companies are subject to numerous risks, including fierce competition, consolidation, adverse political, economic and governmental developments, substantial research and development costs, cuts in government funding, product and technology obsolescence, limited numbers of potential customers and decreased demand for new equipment. In addition, companies involved in the defense industry are also subject to order cancellations, excess capacity, fuel price hikes, adverse changes in international politics and relations, intense global competition, government regulation and cyclical market patterns. Defense companies rely heavily on government demand for their products and services. As a result, these companies could be adversely impacted by future reductions or changes in government spending. Such government spending on defense is not generally correlated with economic cycles, but rather with general political support for this type of spending. There is no assurance that future levels of spending on defense will increase or that such spending will not decrease in the future. |
| PLUS Korea Defense Industry Index ETF | Foreign Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to expropriation, nationalization or adverse political or economic developments. Foreign securities may have relatively low market liquidity and decreased publicly available information about issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. Non-U.S. issuers may also be subject to inconsistent and potentially less stringent accounting, auditing, financial reporting and investor protection standards than U.S. issuers. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. In addition, where all or a portion of the Fund’s portfolio holdings trade in markets that are closed when the Fund’s market is open, there may be valuation differences that could lead to differences between the Fund’s market price and the value of the Fund’s portfolio holdings. |
| PLUS Korea Defense Industry Index ETF | Geographic Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The country or region in which the Fund invests may have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility, each of which may impact the Fund’s investments. |
| PLUS Korea Defense Industry Index ETF | Index Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Concentration Risk. The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated. To the extent that the Fund invests a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified. There may be instances in which the Index, for a variety of reasons including changes in the prices of individual securities held by the Fund, has a larger exposure to a small number of stocks or a single stock relative to the rest of the stocks in the Index. Under such circumstances, the Fund will not deviate from the Index except in rare circumstances or in an immaterial way and therefore the Fund’s returns would be more greatly influenced by the returns of the stock(s) with the larger exposure. |
| PLUS Korea Defense Industry Index ETF | Index Provider Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Index Provider and its agents do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and do not guarantee that the Index will be calculated in accordance with its stated methodology. The Adviser’s mandate as described in this prospectus is to manage the Fund consistently with the Index provided by the Index Provider. The Adviser relies upon the Index provider and its agents to accurately compile, maintain, construct, reconstitute, rebalance, compose, calculate and disseminate the Index accurately. Therefore, losses or costs associated with any Index Provider or agent errors generally will be borne by the Fund and its shareholders. To correct any such error, the Index Provider or its agents may carry out an unscheduled rebalance of the Index or other modification of Index constituents or weightings. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the Index is less commonly used as a benchmark by funds or advisors. For example, during a period where the Index contains incorrect constituents, the Fund tracking the Index would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers. Unusual market conditions or issuer-specific events may cause the Index Provider to postpone a scheduled rebalance, exclude or substitute a security in the Index or undertake other measures which could cause the Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Index due to unusual market conditions or in order, for example, to correct an error in the selection of index constituents. |
| PLUS Korea Defense Industry Index ETF | Industry Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries to the extent the Index concentrates in a particular industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries. The list below is not a comprehensive list of the industries to which the Fund may have exposure over time and should not be relied on as such. As of March 3, 2026, the Index was concentrated in the Aerospace and Defense Industry, as defined by AICS.
Aerospace and Defense Industry Risk. The aerospace and defense industry may be significantly affected by government aerospace and defense regulation, spending policies, and geopolitical stability because companies involved in this industry rely to a significant extent on U.S. (and other) government demand for their products and services. The financial condition of and investor interest in Aerospace and Defense Companies will be negatively influenced by governmental defense spending policies that, outside the occurrence of certain events, such as terrorist attacks, war, and other geopolitical events, are typically under pressure from efforts to control the U.S. (and other) government budgets. The industry’s reliance on the successful development and implementation of new defense and aerospace technologies may result in limited product lines, markets, financial resources, customers, or personnel, all of which may have an adverse effect on profit margins. Products and technologies may face obsolescence due to rapid technological developments and frequent new product introduction, and as such, companies may face unpredictable changes in growth rates, competition for the services of qualified personnel and competition from foreign competitors with lower production costs. |
| PLUS Korea Defense Industry Index ETF | International Closed Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | International Closed Market Trading Risk. Because securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund's net asset value, resulting in premiums or discounts to the Fund’s net asset value that may be greater than those experienced by other exchange-traded funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on the listing exchange for the Fund, on days when the net asset value of the Fund could be significantly affected by events in the relevant foreign markets. |
| PLUS Korea Defense Industry Index ETF | Investable Universe of Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investable Universe of Companies Risk. The investable universe of companies in which the Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s overall portfolio holdings and on Fund performance. |
| PLUS Korea Defense Industry Index ETF | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares. |
| PLUS Korea Defense Industry Index ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular investment, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, the imposition of tariffs, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares, the liquidity of an investment, and may result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund’s shares may widen and the returns on investment may fluctuate. |
| PLUS Korea Defense Industry Index ETF | Mid-Capitalization Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid-Capitalization Companies Risk. Mid capitalization companies may be more vulnerable to adverse general market or economic developments and thus may experience greater price volatility than more established large capitalization companies. Securities of mid capitalization companies may also be less liquid than securities of large capitalization companies and may have more limited trading volumes. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. |
| PLUS Korea Defense Industry Index ETF | Non-Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. The Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index. Additionally, in order to comply with its investment strategies and policies, the Fund portfolio may deviate from the composition of the Index. Accordingly, the Fund's return may underperform the return of the Index. |
| PLUS Korea Defense Industry Index ETF | Non-Diversification Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is non-diversified under the 1940 Act, meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance. |
| PLUS Korea Defense Industry Index ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Fund’s investment adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. |
| PLUS Korea Defense Industry Index ETF | Portfolio Turnover Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk. The Fund’s investment strategy may result in relatively high portfolio turnover, which may result in increased transaction costs and may lower Fund performance. |
| PLUS Korea Defense Industry Index ETF | Premium/Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Premium/Discount Risk. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. The Fund’s investment adviser cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment adviser believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value and the bid/ask spread on the Fund’s shares may widen. |
| PLUS Korea Defense Industry Index ETF | Settlement Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Settlement Risk. Markets in different countries have different clearance and settlement procedures and in certain markets there have been times when settlements have been unable to keep pace with the volume of transactions. Delays in settlement may increase credit risk to the Fund, limit the ability of the Fund to reinvest the proceeds of a sale of securities, and potentially subject the Fund to penalties for its failure to deliver to on-purchasers of securities whose delivery to the Fund was delayed. Delays in the settlement of securities purchased by the Fund may limit the ability of the Fund to sell those securities at times and prices it considers desirable and may subject the Fund to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. The Fund may be required to borrow monies it had otherwise expected to receive in connection with the settlement of securities sold by it, in order to meet its obligations to others. Limits on the ability of the Fund to purchase or sell securities due to settlement delays could increase any variance between the Fund's performance and that of its index. |
| PLUS Korea Defense Industry Index ETF | Small Capitalization Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small Capitalization Companies Risk. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies. |
| PLUS Korea Defense Industry Index ETF | South Korea Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | South Korea Risk. The Fund invests a significant portion of its assets in securities of South Korean issuers and is therefore subject to certain risks specifically associated with investments in the securities of South Korean issuers. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors may have an adverse effect on the South Korean economy. This includes risks associated with the economic, market, regulatory, political, natural disasters and local risks of the Asia-Pacific region, which are heightened as compared to a fund with a more geographically diversified portfolio. The region has historically been highly dependent on global trade with nations (especially the United States and other Asian countries) taking strong roles in both the importing and exporting of goods, any reduction in this trading may have an adverse impact on the Fund’s investments. In addition, South Korea has privatized, or has begun the process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur. Lastly, North and South Korea each have substantial military capabilities, and historical tensions between the two present the ongoing risk of war. Recent incidents involving the North Korean military have heightened tensions between North and South Korea. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and its securities markets. |

To qualify for the favorable tax treatment generally available to a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund must satisfy, among other requirements described in the SAI, certain diversification requirements. Given the concentration of the Fund’s investments in a relatively small number of securities, it may not always be possible for the Fund to fully implement its investment strategy while satisfying these diversification requirements. The Fund’s efforts to pursue its investment strategy may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could be eligible for relief provisions if the failure is due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. If the Fund were to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, its shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC. |
