xETFs Korea AI Semiconductor ETF | Semiconductor Industry Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Semiconductor Industry Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. The Fund is subject to the risk that companies that are in the semiconductor industry may be similarly affected by particular economic or market events. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and such companies may need additional financing, which may be difficult to obtain. Semiconductor companies depend significantly on third-party suppliers and the availability of raw materials and may be adversely affected by supply chain disruptions. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor industry are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, competition from subsidized foreign competitors with lower production costs, tariffs and trade disputes, and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.
Further, the Fund may have significant exposure to issuers involved in high-bandwidth memory (“HBM”), advanced semiconductor packaging, and AI-related semiconductor infrastructure technologies, which may be subject to rapid technological change, concentrated customer demand, and cyclical capital expenditure trends. Because AI is a significant growth driver for the semiconductor industry, the industry may be adversely impacted by uncertainties and outcomes associated with the use and evolution of AI.
xETFs Korea AI Semiconductor 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. These include risks of adverse changes in foreign economic, political, regulatory and other conditions, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. 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. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there also is the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.
xETFs Korea AI Semiconductor ETF | Risk Of Investing In South Korea Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Risk of Investing in South Korea. Investments in South Korean issuers will subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. The South Korean economy may be significantly affected by government policies, changes in global demand for exports, and developments involving key industries such as semiconductors and technology. As a result of uncertain global and Korean economic, social, and political conditions, there has been significant volatility in the stock prices of Korean companies recently. In addition, South Korean issuers are often part of large, family-controlled business groups known as “chaebols,” which may present unique corporate governance risks. These risks may include complex ownership structures, cross-shareholdings, and the concentration of control within a small group of affiliated entities or controlling shareholders, which could result in conflicts of interest, limited shareholder influence, or decisions that are not aligned with the interests of minority shareholders.
In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.
xETFs Korea AI Semiconductor ETF | Single Country Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Single Country Risk. Because the Fund may invest a significant portion of its assets in companies in a specific country and region, the Fund is subject to greater risks of adverse developments in that country, region and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the country or region, even in countries in which the Fund is not invested, may adversely affect the value of investments held by the Fund.
xETFs Korea AI Semiconductor ETF | Foreign Custody And Settlement Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Foreign Custody and Settlement Risk. Investments in foreign securities involve risks related to clearing, settlement, and custody in markets outside the United States. Settlement of foreign transactions may take longer than in U.S. markets, which could delay the Fund’s receipt of proceeds. In less developed markets, custody and settlement systems may be less reliable or subject to limited oversight, increasing the risk of loss, delays, or difficulties in selling securities.
xETFs Korea AI Semiconductor ETF | U.S.-China Chip-Related Export Restrictions Risk Member  
Prospectus [Line Items]  
Risk [Text Block] U.S.-China Chip-Related Export Restrictions Risk. The United States, China, and other jurisdictions maintain export control, trade, and economic sanctions regimes that restrict the transfer of certain semiconductors, related equipment, software, and technologies. In recent years, the United States and other governments have imposed, and may continue to expand, restrictions on the export of advanced chips, semiconductor manufacturing equipment, computing power, or related technologies to China and China‑based entities. Such measures may adversely affect companies in which the Fund invests by limiting access to key customers, disrupting supply chains, constraining end‑market demand, or increasing compliance costs. These restrictions could negatively impact the revenues, profitability, competitive position, and growth prospects of companies in which the Fund invests.
xETFs Korea AI Semiconductor ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Currency Exchange Rate Risk. The Fund invests in securities denominated in South Korean won. Investments denominated in non-U.S. currencies and investments in securities denominated or quoted in non‑U.S. currencies, currency exchange rates or interest rates are subject to non-U.S. currency risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Because the Fund’s NAV is determined on the basis of U.S. dollars, the U.S. dollar value of your investment in the Fund may go down if the value of the local currency of the non-U.S. markets in which the Fund invests depreciates against the U.S. dollar. This is true even if the local currency value of securities in the Fund’s holdings goes up. Conversely, the U.S. dollar value of your investment in the Fund may go up if the value of the local currency appreciates against the U.S. dollar. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
xETFs Korea AI Semiconductor ETF | Counterparty Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Counterparty Risk. Counterparty risk is the risk that a counterparty to Fund transactions, including swap agreements, will be unable or unwilling to perform its contractual obligation to the Fund. The Fund may use swap agreements to gain exposure to one or more issuers. Through these investments, the Fund is exposed to the risk that the counterparty may be unwilling or unable to make timely payments contemplated by such arrangements or otherwise to meet its contractual obligations (i.e., counterparty credit risk). If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your Shares in the Fund will decrease.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. To the extent the Fund’s counterparties are concentrated in the financial services sector, the Fund bears the risk that those counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting that economic sector. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.
xETFs Korea AI Semiconductor ETF | Derivatives Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. The Fund’s derivative investments have risks, including the imperfect correlation between the value of such instruments and the underlying assets or index; the loss of principal, including the potential loss of amounts greater than the initial amount invested in the derivative instrument; and illiquidity of the derivative investments. The derivatives used by the Fund may give rise to a form of leverage. Leverage magnifies the potential for gain and may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at inopportune times (e.g., at a loss to comply with limits on leverage imposed by the 1940 Act or when the Adviser otherwise would have preferred to hold the investment) or to meet redemption requests. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. To the extent the Fund invests in such derivative instruments, the value of the Fund’s portfolio is likely to experience greater volatility over short-term periods.
◦Swap Agreements Risk. Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying security). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a FCM
and/or cleared through a clearinghouse that serves as a central counterparty. Swap agreements may be subject to fees and expenses, and by investing in swaps indirectly through the Fund, a shareholder will bear the expenses of such derivatives in addition to expenses of the Fund. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

xETFs Korea AI Semiconductor ETF | Active Management Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Active Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure in implementing strategies for the Fund. The Fund may invest in complex instruments, including swap agreements. Such instruments may create enhanced risks for the Fund, and the Adviser’s ability to control the Fund’s level of risk will depend on the Adviser’s skill in managing such instruments. In addition, the Adviser’s evaluations and assumptions regarding investments, interest rates, inflation, and other factors may not successfully achieve the Fund’s investment objective given actual market conditions.
xETFs Korea AI Semiconductor ETF | Cash Transaction Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Cash Transaction Risk. The Fund may effect creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. 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. Further, effecting purchases and redemptions primarily in cash may cause the Fund to incur certain costs, such as portfolio transaction costs. These costs can decrease the Fund’s NAV if not offset by an AP transaction fee.
xETFs Korea AI Semiconductor ETF | Cybersecurity Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders.
xETFs Korea AI Semiconductor ETF | Depositary Receipt Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Depositary Receipt Risk. Depositary receipts, including ADRs and GDRs, involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). GDRs are similar to ADRs in that they are certificates evidencing ownership of shares of a foreign issuer; however, GDRs may be issued in bearer form and denominated in other currencies and are generally designed for use in specific or multiple securities markets outside the U.S. When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.
xETFs Korea AI Semiconductor 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 investments, 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.
xETFs Korea AI Semiconductor ETF | ETF Risks Member  
Prospectus [Line Items]  
Risk [Text Block] ETF Risks. The Fund is an ETF and, as a result of its structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. Shares may trade at a material discount to NAV and possibly face delisting if either: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares Risk. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading Risk. Although Shares are listed for trading on The Nasdaq Stock Market, LLC (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than the Shares.

Risk [Text Block] Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. Shares may trade at a material discount to NAV and possibly face delisting if either: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
xETFs Korea AI Semiconductor ETF | ETF Risks, Costs Of Buying Or Selling Shares Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Costs of Buying or Selling Shares Risk. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

Risk [Text Block] Trading Risk. Although Shares are listed for trading on The Nasdaq Stock Market, LLC (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than the Shares.
xETFs Korea AI Semiconductor ETF | Foreign Withholding Tax Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Foreign Withholding Tax Risk. Income earned on foreign stocks and securities may be subject to foreign withholding taxes, which could reduce the Fund’s returns. In particular, dividends paid by Korean issuers are generally subject to Korean withholding tax (currently at a rate of 22%, subject to reduction under applicable tax treaties). The Fund may not be able to fully recover or offset such withholding taxes, and any such taxes will reduce the Fund’s income and, accordingly, the amount of distributions to shareholders.
xETFs Korea AI Semiconductor ETF | Information Technology Sector Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Information Technology Sector Risk. The information technology sector includes companies engaged in internet software and services, technology hardware and storage peripherals, electronic equipment instruments and components, and semiconductors and semiconductor equipment. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face rapid product obsolescence due to technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Failure to introduce new products, develop and maintain a loyal customer base, or achieve general market acceptance for their products could have a material adverse effect on a company’s business. Companies in the information technology sector are heavily dependent on intellectual property and the loss of patent, copyright and trademark protections may adversely affect the profitability of these companies.
xETFs Korea AI Semiconductor ETF | Large Shareholder And Large-Scale Redemption Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Large Shareholder and Large-Scale Redemption Risk. Certain shareholders of the Fund, including an Authorized Participant, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.
xETFs Korea AI Semiconductor ETF | Liquidity Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund's returns because the Fund may be unable to transact at advantageous times or prices.
xETFs Korea AI Semiconductor ETF | Market Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as well as events that impact specific issuers. The Fund’s NAV and market price, like security prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. In addition, government actions or interventions (including, but not limited, to the threat or imposition of tariffs, trade restrictions, currency restrictions or similar actions) as well as developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters, or other conditions or events have in the past and may in the future result in volatility in financial markets and reduced liquidity in equity, credit, and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
xETFs Korea AI Semiconductor ETF | New Fund Risk Member  
Prospectus [Line Items]  
Risk [Text Block] New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
xETFs Korea AI Semiconductor ETF | Other Investment Companies Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies Risk. The Fund may invest in shares of other investment companies, including U.S.-listed ETFs. As a shareholder of another investment company, the Fund bears its proportionate share of that company’s fees and expenses in addition to the Fund’s own fees and expenses, and the Fund’s performance depends in part on the performance of the underlying fund. Shares of ETFs may trade at prices that differ from their net asset value, and the Fund may pay a premium or receive a discount relative to net asset value when purchasing or selling such shares.
xETFs Korea AI Semiconductor ETF | Tax Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Tax Risk. At the end of each quarter of the Fund’s taxable year, the Fund’s assets must be diversified so that (a) at least 50% of the value of the Fund’s total assets is represented by cash and cash items, U.S. government securities, securities of other regulated investment companies (“RICs”), and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (b) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, the securities (other than securities of other RICs) of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the “Diversification Requirement”). The determination of the value and the identity of the issuer of derivative investments that the Fund may invest in are often unclear for purposes of the Diversification Requirement described above. Although the Fund intends to carefully monitor its investments to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service (“IRS”) will agree with the Fund’s determination of the issuer under the Diversification Requirement with respect to such derivatives. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a RIC, 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.
xETFs Korea AI Semiconductor ETF | Volatility Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Volatility Risk. The value of certain of the Fund’s investments, including swaps, is subject to market risk. Market risk is the risk that the value of the investments to which the Fund is exposed will fall, which could occur due to general market or economic conditions or other factors.
xETFs Korea AI Semiconductor ETF | Whipsaw Markets Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Whipsaw Markets Risk. The Fund may be subject to the forces of “whipsaw” markets (as opposed to choppy or stable markets), in which significant price movements develop but then repeatedly reverse. “Whipsaw” describes a situation where a security’s price is moving in one direction but then quickly pivots to move in the opposite direction. Such market conditions could cause substantial losses to the Fund.
xETFs Korea AI Semiconductor ETF | Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund
xETFs Korea AI Semiconductor ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Semiconductor Industry Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Semiconductor Industry Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. The Fund is subject to the risk that companies that are in the semiconductor industry may be similarly affected by particular economic or market events. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and such companies may need additional financing, which may be difficult to obtain. Semiconductor companies depend significantly on third-party suppliers and the availability of raw materials and may be adversely affected by supply chain disruptions. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they
may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor industry are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, competition from subsidized foreign competitors with lower production costs, tariffs and trade disputes, and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.
Further, the Fund may have significant exposure to issuers involved in high-bandwidth memory (“HBM”), advanced semiconductor packaging, and AI-related semiconductor infrastructure technologies, which may be subject to rapid technological change, concentrated customer demand, and cyclical capital expenditure trends. Because AI is a significant growth driver for the semiconductor industry, the industry may be adversely impacted by uncertainties and outcomes associated with the use and evolution of AI.
xETFS 2x Long Daily Korea AI Semiconductor 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. These include risks of adverse changes in foreign economic, political, regulatory and other conditions, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. 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. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there also is the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Risk Of Investing In South Korea Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Risk of Investing in South Korea. Investments in South Korean issuers will subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. The South Korean economy may be significantly affected by government policies, changes in global demand for exports, and developments involving key industries such as semiconductors and technology. As a result of uncertain global and Korean economic, social, and political conditions, there has been significant volatility in the stock prices of Korean companies recently. In addition, South Korean issuers are often part of large, family-controlled business groups known as “chaebols,” which may present unique corporate governance risks. These risks may include complex ownership structures, cross-shareholdings, and the concentration of control within a small group of affiliated entities or controlling shareholders, which could result in conflicts of interest, limited shareholder influence, or decisions that are not aligned with the interests of minority shareholders.
In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Single Country Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Single Country Risk. Because the Fund may invest a significant portion of its assets in companies in a specific country and region, the Fund is subject to greater risks of adverse developments in that country, region and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the country or region, even in countries in which the Fund is not invested, may adversely affect the value of investments held by the Fund.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Foreign Custody And Settlement Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Foreign Custody and Settlement Risk. Investments in foreign securities involve risks related to clearing, settlement, and custody in markets outside the United States. Settlement of foreign transactions may take longer than in U.S. markets, which could delay the Fund’s receipt of proceeds. In less developed markets, custody and settlement systems may be less reliable or subject to limited oversight, increasing the risk of loss, delays, or difficulties in selling securities.
xETFS 2x Long Daily Korea AI Semiconductor ETF | U.S.-China Chip-Related Export Restrictions Risk Member  
Prospectus [Line Items]  
Risk [Text Block] U.S.-China Chip-Related Export Restrictions Risk. The United States, China, and other jurisdictions maintain export control, trade, and economic sanctions regimes that restrict the transfer of certain semiconductors, related equipment, software, and technologies. In recent years, the United States and other governments have imposed, and may continue to expand, restrictions on the export of advanced chips, semiconductor manufacturing equipment, computing power, or related technologies to China and China‑based entities. Such measures may adversely affect companies in which the Fund invests by limiting access to key customers, disrupting supply chains, constraining end‑market demand, or increasing compliance costs. These restrictions could negatively impact the revenues, profitability, competitive position, and growth prospects of companies in which the Fund invests.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Currency Exchange Rate Risk. The Fund invests in securities denominated in South Korean won. Investments denominated in non-U.S. currencies and investments in securities denominated or quoted in non‑U.S. currencies, currency exchange rates or interest rates are subject to non-U.S. currency risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Because the Fund’s NAV is determined on the basis of U.S. dollars, the U.S. dollar value of your investment in the Fund may go down if the value of the local currency of the non-U.S. markets in which the Fund invests depreciates against the U.S. dollar. This is true even if the local currency value of securities in the Fund’s holdings goes up. Conversely, the U.S. dollar value of your investment in the Fund may go up if the value of the local currency appreciates against the U.S. dollar. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Counterparty Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Counterparty Risk. Counterparty risk is the risk that a counterparty to Fund transactions (e.g., swap transactions) will be unable or unwilling to perform its contractual obligation to the Fund. The Fund expects to use swap agreements to gain exposure to the Underlying Basket without purchasing the Underlying Basket directly in order to achieve its investment objective. Through these investments, the Fund is exposed to the risk that the counterparty may be unwilling or unable to make timely payments contemplated by such arrangements or otherwise to meet its contractual obligations (i.e., counterparty credit risk). If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your Shares in the Fund will decrease.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. To the extent the Fund’s counterparties are concentrated in the financial services sector, the Fund bears the risk that those counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting that economic sector. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Derivatives Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. The Fund’s derivative investments have risks, including the imperfect correlation between the value of such instruments and the underlying assets or index; the loss of principal, including the potential loss of amounts greater than the initial amount invested in the derivative instrument; and illiquidity of the derivative investments. The derivatives used by the Fund may give rise to a form of leverage. Leverage magnifies the potential for gain and may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at inopportune times (e.g., at a loss to comply with limits on leverage imposed by the 1940 Act or when the Adviser otherwise would have preferred to hold the investment) or to meet redemption requests. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. To the extent the Fund invests in such derivative instruments, the value of the Fund’s portfolio is likely to experience greater volatility over short-term periods.
◦Swap Agreements Risk. Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the Underlying Basket). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a FCM and/or cleared through a clearinghouse that serves as a central counterparty. Swap agreements may be subject to fees and expenses, and by investing in swaps indirectly through the Fund, a shareholder will bear the expenses of such derivatives in addition to expenses of the Fund. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

Prospectus [Line Items]  
Risk [Text Block] Active Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure in implementing strategies for the Fund. The Fund invests in complex instruments, including swap agreements. Such instruments may create enhanced risks for the Fund, and the Adviser’s ability to control the Fund’s level of risk will depend on the Adviser’s skill in managing such instruments. In addition, the Adviser’s evaluations and assumptions regarding investments, interest rates, inflation, and other factors may not successfully achieve the Fund’s investment objective given actual market conditions.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Cash Transaction Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Cash Transaction Risk. The Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. 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. Further, effecting purchases and redemptions primarily in cash may cause the Fund to
incur certain costs, such as portfolio transaction costs. These costs can decrease the Fund’s NAV if not offset by an AP transaction fee.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Cybersecurity Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Depositary Receipt Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Depositary Receipt Risk. Depositary receipts, including ADRs and GDRs, involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). GDRs are similar to ADRs in that they are certificates evidencing ownership of shares of a foreign issuer; however, GDRs may be issued in bearer form and denominated in other currencies and are generally designed for use in specific or multiple securities markets outside the U.S. When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. Because the Underlying Shares trade on foreign exchanges that may be closed when the Fund’s primary listing exchange is open, the Fund may experience premiums and discounts greater than those of funds without exposure to such Underlying Shares.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Early Close/Trading Halt Risk Member

Risk [Text Block] Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific investments, 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.
xETFS 2x Long Daily Korea AI Semiconductor ETF | ETF Risks Member  
Prospectus [Line Items]  
Risk [Text Block] ETF Risks. The Fund is an ETF and may invest in other ETFs. As a result, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. Shares may trade at a material discount to NAV and possibly face delisting if either: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares Risk. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading Risk. Although Shares are listed for trading on The Nasdaq Stock Market, LLC (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than the Shares.

Risk [Text Block] Foreign Withholding Tax Risk. Income earned on foreign stocks and securities may be subject to foreign withholding taxes, which could reduce the Fund’s returns. In particular, dividends paid by Korean issuers are generally subject to Korean withholding tax (currently at a rate of 22%, subject to reduction under applicable tax treaties). The Fund may not be able to fully recover or offset such withholding taxes, and any such taxes will reduce the Fund’s income and, accordingly, the amount of distributions to shareholders.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Information Technology Sector Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Information Technology Sector Risk. The information technology sector includes companies engaged in internet software and services, technology hardware and storage peripherals, electronic equipment instruments and components, and semiconductors and semiconductor equipment. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face rapid product obsolescence due to technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Failure to introduce new products, develop and maintain a loyal customer base, or achieve general market acceptance for their products could have a material adverse effect on a company’s business. Companies in the information technology sector are heavily dependent on intellectual property and the loss of patent, copyright and trademark protections may adversely affect the profitability of these companies.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Liquidity Risk Member

Risk [Text Block] Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund's returns because the Fund may be unable to transact at advantageous times or prices.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Market Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as well as events that impact specific issuers. The Fund’s NAV and market price, like security prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. In addition, government actions or interventions (including, but not limited, to the threat or imposition of tariffs, trade restrictions, currency restrictions or similar actions) as well as developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters, or other conditions or events have in the past and may in the future result in volatility in financial markets and reduced liquidity in equity, credit, and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
xETFS 2x Long Daily Korea AI Semiconductor ETF | New Fund Risk Member  
Prospectus [Line Items]  
Risk [Text Block] New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Other Investment Companies Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies Risk. The risks of investment in other investment companies, including ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. The Fund will incur higher and duplicative expenses when it invests in other investment companies, however, the Adviser will not collect management fees for managing Fund assets directly invested in affiliated ETFs; this waiver does not apply to indirect exposure obtained through swap agreements or other derivative instruments referencing affiliated ETFs. Investments in ETFs are also subject to the “ETF Risks” described above.
◦Affiliated ETF Risk. To the extent the Fund invests in an affiliated ETF, such as the KSMH ETF, the Fund’s investment performance and risks will be directly related to the investment performance and risks of such affiliated ETF. In addition, the Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Tax Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Tax Risk. At the end of each quarter of the Fund’s taxable year, the Fund’s assets must be diversified so that (a) at least 50% of the value of the Fund’s total assets is represented by cash and cash items, U.S. government securities, securities of other regulated investment companies (“RICs”), and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (b) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, the securities (other than securities of other RICs) of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the “Diversification Requirement”). The determination of the value and the identity of the issuer of derivative investments that the Fund may invest in are often unclear for purposes of the Diversification Requirement described above. Although the Fund intends to carefully monitor its investments to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service (“IRS”) will agree with the Fund’s determination of the issuer under the Diversification Requirement with respect to such derivatives. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a RIC, 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.

Prospectus [Line Items]  
Risk [Text Block] Whipsaw Markets Risk. The Fund may be subject to the forces of “whipsaw” markets (as opposed to choppy or stable markets), in which significant price movements develop but then repeatedly reverse. “Whipsaw” describes a situation where a security’s price is moving in one direction but then quickly pivots to move in the opposite direction. Such market conditions could cause substantial losses to the Fund.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Effects Of Compounding And Market Volatility Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Effects of Compounding and Market Volatility Risk. The Fund’s performance for periods greater than a trading day will be the result of each day's returns compounded over the period, which is likely to differ from 200% of the Underlying Basket’s performance, before fees and expenses. Compounding has a significant impact on funds that are leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Basket during the shareholder’s holding period.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Basket volatility; b) Underlying Basket performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to securities of the Underlying Basket. The chart below provides examples of how Underlying Basket volatility and its return could affect the Fund’s performance. The chart shows estimated Fund returns for a number of combinations of Underlying Basket volatility and Underlying Basket performance over a one-year period. Actual Fund returns are expected to vary from these estimates. Performance shown in the chart assumes that: (i) no dividends were paid with respect to the securities included in the Underlying Basket; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher Underlying Basket volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of the Underlying Basket.
As shown in the chart below, the Fund would be expected to lose 6.1% if the Underlying Basket provided no return over a one year period during which the Underlying Basket experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Basket’s return is flat. For instance, if the Underlying Basket’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Basket return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Basket and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Basket. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above. The volatility of exchange traded securities or instruments that reflect the value of the Underlying Basket may differ from the volatility of the value of the Underlying Basket.

Risk [Text Block] Intra-Day Investment Risk. The intra-day performance of Fund shares traded in the secondary market generally will be different from the performance of the Fund when measured from one NAV calculation time to the next. When shares are bought intra-day, the performance of the Fund’s shares will generally be higher or lower than that of the Underlying Basket until the Fund’s next NAV calculation time.
xETFS 2x Long Daily Korea AI Semiconductor ETF | Leverage Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money than a fund that does not utilize leverage. An investment in the Fund typically results in the magnification of a decline in the daily performance of the Underlying Basket, resulting in a larger loss being incurred than if there was no leverage utilized. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in the Underlying Basket, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could lose an amount greater than its net assets in the event of an Underlying Basket decline of more than 50% of the Underlying Basket. This would result in a total loss of a shareholder’s investment in one day even if the Underlying Basket subsequently reverses all or a portion of its previous movement prior to the end of the day. A total loss of a shareholder’s investment in the Fund may occur in a single day even if the Underlying Basket’s value does not move fully opposite from the Fund’s investment objective. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Underlying Basket and may increase the volatility of the Fund.
Under market circumstances that cause leverage to be expensive or unavailable, the Fund may increase its transaction fee on creation unit transactions, change its investment objective, reduce its leverage or close.

Risk [Text Block] Collateral Securities Risk. Collateral may include obligations issued or guaranteed by the U.S. government and its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury, as well as money market funds, and corporate debt securities, such as commercial paper. Some securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may not be backed by the full faith and credit of the United States, in which case the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. government and its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. Although the Fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund. The Fund’s investments in U.S. government securities will change in value in response to interest rate changes and other factors, such as the perception of an issuer’s creditworthiness. Money market funds are subject to management fees and other expenses. Therefore, investments in money market funds will cause the Fund to bear indirectly a proportional share of the fees and costs of the money market funds in which it invests. At the same time, the Fund will continue to pay its own management fees and expenses with respect to all of its assets, including any portion invested in the shares of the money market fund. It is possible to lose money by investing in money market funds. Corporate debt securities such as commercial paper generally are short-term unsecured promissory notes issued by businesses. Corporate debt may be rated investment-grade or below investment-grade and may carry variable or floating rates of interest. Corporate debt securities carry both credit risk and interest rate risk. Credit risk is the risk that the Fund could lose money if the issuer of a corporate debt security is unable to pay interest or repay principal when it is due. Interest rate risk is the risk that interest rates rise and fall over time. For example, the value of fixed-income securities generally decrease when interest rates rise, which may cause the Fund’s value to decrease. Also, investments in fixed-income securities with longer maturities fluctuate more in response to interest rate changes. Some corporate debt securities that are rated below investment-grade generally are considered speculative because they present a greater risk of loss, including default, than higher quality debt securities.

Prospectus [Line Items]  
Risk [Text Block] Daily Underlying Basket Correlation Risk. A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Underlying Basket and therefore achieve its daily leveraged investment objective. The Fund’s exposure to the Underlying Basket is impacted by changes in the value of the Underlying Basket. Because of this, it is unlikely that the Fund will be perfectly exposed to the Underlying Basket at the end of each day. The possibility of the Fund being materially over- or under-exposed to the Underlying Basket increases on days when the value of the Underlying Basket is volatile near the close of the trading day.
Market disruptions, regulatory restrictions, fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, accounting standards and their application to income items, disruptions, illiquidity or high volatility in the markets for the securities or derivatives held by the Fund, and regulatory and tax considerations, among other factors, will also adversely affect the Fund’s ability to adjust exposure to meet its daily leveraged investment objective. The Fund may be required to trade more frequently or may refrain from taking certain positions to ensure compliance with regulatory
restrictions or to ensure qualification as a registered investment company or to improve tax efficiency, or for other reasons, each of which may negatively impact the Fund’s leveraged correlation to the Underlying Basket or increase its required distributions.
The derivatives or investments the Fund utilizes to obtain exposure may not provide the expected correlation to the Underlying Basket, resulting in the Fund not performing as expected. Additionally, the Fund may not have investment exposure to all of the securities in the Underlying Basket. The Fund may also invest in or have exposure to securities that are not included in the Underlying Basket. The Fund may measure its correlation to the performance of one of more ETFs rather than the Underlying Basket. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Basket and impacting the Fund’s correlation to the value of the Underlying Basket.
Due to the Underlying Basket including instruments that trade on a different market than the Fund, the Fund's return may vary from a multiple of the performance of the Underlying Basket because different markets may close before the national securities listing exchange where Shares are listed opens or may not be open for business on the same calendar days as the Fund. Additionally, due to differences in trading hours, and because the value of the Underlying Basket may be calculated using prices obtained at times other than the Fund’s NAV calculation time or due to the fair valuation of Underlying Basket securities, the Fund’s performance may not correlate with the Underlying Basket.

Risk [Text Block] Affiliated ETF Risk. To the extent the Fund invests in an affiliated ETF, such as the KSMH ETF, the Fund’s investment performance and risks will be directly related to the investment performance and risks of such affiliated ETF. In addition, the Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund.

xETFS 2x Long Daily Korea AI Semiconductor ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
