| Risk [Text Block] | An investment in the Fund entails risk. The Fund may not achieve its leveraged investment objective and there is a risk that you could lose all of your money invested in the Fund. Additionally, the Fund presents risks that are not traditionally associated with other mutual funds and ETFs. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield or total return. For more information about the risks of investing in the Fund, see the section in the Fund’s prospectus entitled “Additional Information about the Principal Risks of Investing in the Funds.” Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

| Leverage Shares 2X Long NScale Daily ETF | Effects Of Compounding And Market Volatility Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and 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 very likely to differ from 200% of the Underlying Security’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 Security during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security 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 the Underlying Security. The chart below provides examples of how volatility and its return could affect the Fund’s performance. The chart shows estimated Fund returns for a number of combinations of volatility and performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to the Underlying Security; (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 volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of the Underlying Security.
During periods of higher Underlying Security volatility, the volatility of the Underlying Security may affect the Fund’s return as much as, or more than, the return of the Underlying Security. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
As shown in the chart below, the Fund would be expected to lose 6.1% if the Underlying Security provided no return over a one-year period during which the Underlying Security 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 Security’s return is flat. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative 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 Security 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 Security. 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 or in “Daily Correlation Risk” below.
As of the date of this Prospectus, the Underlying Security has not yet traded on an exchange for a one-year calendar period and, therefore, does not have an annualized historical volatility rate or total return performance available to report. When available, historical volatility and performance are not indications of what the Underlying Security volatility and performance will be in the future. The volatility of U.S. exchange-traded securities or instruments that reflect the value of the Underlying Security may differ from the volatility of the Underlying Security.
For information regarding the effects of volatility and performance on the long-term performance of the Fund, see “Additional Information About Investment Techniques and Policies.”

| Risk [Text Block] | Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of the Underlying Security will be magnified. 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 Security, not including the costs of financing leverage and other operating expenses, which would further reduce its value. If the Underlying Security declines by 50% or more in a single trading day, the Fund would lose all or substantially all of its value. This would result in a total loss of a shareholder’s investment in one day even if the Underlying Security subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if the Underlying Security does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Underlying Security and may increase the volatility of the Fund.
To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close.

| Leverage Shares 2X Long NScale Daily ETF | Nscale Limited Investing Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Nscale Limited Investing Risk. Issuer-specific attributes may cause an investment in Nscale Limited to be more volatile than the market generally. In addition to risks associated with the software and services industry, Nscale faces risks associated with its limited operating history, rapid expansion, significant net losses and substantial capital requirements. The company depends on continued demand for artificial intelligence computing capacity and derives a significant portion of its revenue from a limited number of customers. Its growth depends on its ability to secure land and reliable power, construct and operate data centers, obtain advanced computing equipment, complete projects on schedule and convert contracted capacity into revenue. Nscale also faces risks from construction delays and cost overruns, equipment and power shortages, customer defaults or contract terminations, substantial indebtedness, technological change, cybersecurity incidents, service interruptions, international operations, regulatory requirements and intense competition. Any of these risks could have a significant negative impact on the company’s business.
Nscale has filed a registration statement relating to its proposed IPO. The timing and completion of the offering are subject to regulatory review, market conditions and other factors, and the offering may be delayed or may not be completed. If the offering is completed, the Underlying Security will have a limited public trading history upon which investors can evaluate its performance, and its market price may be volatile. The trading price of the Underlying Security may fluctuate significantly due to company-specific developments, changes in investor expectations, general market conditions, lock-up expirations for pre-IPO shareholders, changes in trading volume, the entry or exit of large shareholders or other factors unrelated to Nscale’s operating performance.

| Leverage Shares 2X Long NScale Daily ETF | Derivatives Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks. Investing in derivatives may expose the Fund to greater risks, and may result in larger losses or smaller gains, than investing directly in the reference asset underlying those derivatives, which may prevent the Fund from achieving its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.
The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective.
Swap Agreements. The Fund expects to use swap agreements to achieve its investment objective. Swap agreements are entered into primarily with major global financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive regulatory protection, which may expose investors to significant losses.
The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective.
Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies, national and international political and economic events, changes in the actual or implied volatility of the reference asset, and the time remaining until expiration of the option contract. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. Depending on their terms and exercise style, options held by a Fund may be exercisable at expiration or at any time prior to expiration. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.
FLEX Options. FLEX Options are exchange-traded options contracts with uniquely customizable terms like exercise price, style, and expiration date. Due to their customization and potentially unique terms, FLEX Options may be less liquid than other securities, such as standard exchange listed options. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price.
These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Risk [Text Block] | Government Regulation of Derivatives Risk. It is possible that government regulation of various types of derivative instruments, including swap agreements, may limit or prevent the Fund from using such instruments as a part of its investment strategy, and could ultimately prevent the Fund from being able to achieve its investment objective. It is impossible to predict fully the effects of legislation and regulation in this area, but the effects could be substantial and adverse.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Artificial Intelligence (“AI”) Risk. Companies that rely on, develop, integrate, or provide infrastructure supporting artificial intelligence technologies face risks related to the complexity, cost, and uncertainty of AI development and deployment. AI systems may produce inaccurate, biased, unreliable, or unintended results, and may fail to perform as expected in real-world applications. The use and development of AI may be subject to heightened regulatory scrutiny, evolving legal and compliance requirements, and increased liability related to data privacy, cybersecurity, intellectual property, and ethical considerations. Significant investments in AI and related infrastructure, talent, and research may not generate anticipated returns, and rapid technological change may render existing AI technologies or supporting infrastructure obsolete or less competitive. Demand for AI-related infrastructure may not develop or be sustained at anticipated levels. In addition, increased competition from companies that develop, deploy, or support AI more effectively or at lower cost could adversely affect market position, operating results, or financial condition.

| Leverage Shares 2X Long NScale Daily ETF | Counterpartycollateral Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty/Collateral Risk. If a counterparty is unwilling or unable to make timely payments, meet its contractual obligations or return holdings that are subject to the agreement with the counterparty, the Fund may lose money or may be unable to meet its daily leveraged investment objective.
In addition, because the Fund may enter into swap agreements with a limited number of counterparties, this increases the Fund’s exposure to counterparty credit risk. 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 leveraged investment objective or rebalance properly, which may result in significant losses to the Fund, or the Fund may decide to change its leveraged investment objective. The risk that no suitable counterparties will enter into or continue to provide swap exposure to the Fund may be increased when there is significant market volatility.
Collateral pledged by a counterparty may be insufficient to fully mitigate credit exposure in the event of a default. This risk may arise from declines in collateral value, limited marketability, legal or perfection issues, or challenges in enforcing security interests. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Leverage Shares 2X Long NScale Daily ETF | Rebalancing Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Leverage Shares 2X Long NScale Daily ETF | Intraday Investment Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intraday Investment Risk. The intraday performance of Fund shares traded in the secondary market will be different from the performance of the Fund when measured from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Therefore, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s stated investment objective.
If there is a significant intraday market event and/or the Underlying Security experiences a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close prior to the close of trading on the Exchange (defined below) and experience significant losses.

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Leverage Shares 2X Long NScale Daily ETF | Daily Correlation Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. The Fund’s exposure to the Underlying Security is impacted by the Underlying Security’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to the Underlying Security at the end of each day. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.
The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with the Underlying Security. The Fund may 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 Security. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of the Underlying Security. Any of these factors could decrease the correlation between the performance of the Fund and the Underlying Security and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Foreign Issuer Risk. The Underlying Security is issued by a non-U.S. company and is subject to risks associated with foreign issuers. Foreign securities may be more volatile and less liquid than U.S. securities, and the issuer may be subject to different accounting, auditing, financial reporting and disclosure standards, which may result in less publicly available information. The issuer’s operations and financial results may be affected by economic, political or social conditions in its home country or region, including governmental intervention or geopolitical developments. Investments in foreign issuers are also subject to currency risk and may be affected by changes in exchange rates relative to the U.S. dollar. Foreign markets may have different trading, settlement and regulatory practices, which may increase operational risks.

| Leverage Shares 2X Long NScale Daily ETF | Concentration Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Concentration Risk. The Fund will be concentrated in the industry to which the Underlying Security is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which the Underlying Security is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio that is broadly diversified over several industries or sectors. As of the date of this prospectus, the Underlying Security is expected to be assigned to the software and services industry.
Software and Services Industry Risk. Companies in the software and services industry are subject to intense competition, rapid technological change, evolving industry standards and changing customer preferences. The success of these companies depends on their ability to develop, introduce and support new products and services, attract and retain skilled personnel and protect their intellectual property. Software and services companies may also be adversely affected by pricing pressures, cybersecurity incidents, changing technology spending patterns and the risk of product obsolescence.

| Risk [Text Block] | Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund and/or the Fund’s service providers, including the Adviser, market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Adviser, other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

| Risk [Text Block] | Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective. Global trade policies, including tariffs, could also materially adversely affect the performance of the Fund’s holdings.

| Risk [Text Block] | Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate.

| Risk [Text Block] | Indirect Investment Risk. The issuer of the Underlying Security is not affiliated with the Trust, the Adviser or any affiliate thereof and is not involved with this offering in any way and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund and any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

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

| Risk [Text Block] | Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, deposit accounts and repurchase agreements. Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

| Risk [Text Block] | Repurchase Agreements Risk. The Fund may enter into repurchase agreements. In a repurchase agreement, a party sells a security, commonly a U.S. government security, and agrees to buy the security back at a specific price at a specified later time. A repurchase agreement exposes the Fund to the risk that the party that sells the security may default on its obligation to repurchase it. The Fund may lose money if it cannot sell the security at the agreed-upon time and price or the security loses value before it can be sold.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), 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. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intraday (premium) or less than the NAV intraday (discount). 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. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

| Risk [Text Block] | Early Close/Trading Halt Risk. The risk that an exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. The ability to trade certain securities or financial instruments may be restricted, which may result in a fund being unable to buy or sell certain securities or financial instruments. In these circumstances, a fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Risk [Text Block] | Cash Transaction Risk. The Fund will generally effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and will incur brokerage and financing costs related to buying and selling securities or obtaining derivative exposure to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an AP, the Fund will bear such costs, which will decrease the Fund’s net asset value.

| Risk [Text Block] | Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter and meet annual distribution requirements.
The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, including gaining exposure to the Underlying Security through the use of swaps, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders and were ineligible to or were not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

| Risk [Text Block] | IPO Risk. The Fund expects to commence operations on or about the same date as the Underlying Security commences trading in connection with its IPO. As a result, the Fund will seek exposure to the Underlying Security, consistent with its investment objective, during a period in which the Underlying Security has a limited trading history, limited publicly available information, uncertain market valuation and potentially significant price volatility. Trading in the Underlying Security may be subject to substantial fluctuations in price, wide bid-ask spreads, trading halts, limited liquidity, price discovery challenges and other market disruptions that are more common following an IPO. The Fund may have difficulty obtaining exposure to the Underlying Security on terms that are consistent with its investment objective, particularly during the initial days or weeks following the IPO, which may cause the Fund not to meet its investment objective during this time. In addition, options, swaps or other derivatives referencing the Underlying Security may not be immediately available, may have limited liquidity, may be more expensive than anticipated or may not provide the desired exposure. The Fund’s performance, ability to achieve its investment objective and ability to rebalance its portfolio may be adversely affected by these conditions. These risks are likely to be heightened on the first day of trading and during the period immediately following the IPO.

| Risk [Text Block] | Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that the Underlying Security’s value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the Underlying Security. Under such circumstances, the market for the Underlying Security may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of the Underlying Security and may impact the ability of the Fund to achieve its investment objective.
In certain cases, the market for the Underlying Security and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of the Underlying Security and correlated derivative instruments. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Risk [Text Block] | Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active secondary market trading of the Shares could cause more frequent creation and redemption activities, which would increase the number of portfolio transactions. High levels of portfolio transactions may cause higher transaction costs because of increased broker commissions resulting from such transactions and increased taxable capital gains. The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise most of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher. |

| Leverage Shares 2X Short NScale Daily ETF | Effects Of Compounding And Market Volatility Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk. The Fund has a daily inverse leveraged investment objective and 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 very likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are leveraged (and this impact can be more severe for inverse leveraged products) 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 Security during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security 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 the Underlying Security. The chart below provides examples of how volatility and its return could affect the Fund’s performance. The chart shows estimated Fund returns for a number of combinations of volatility and performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to the Underlying Security; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged short 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 volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
During periods of higher Underlying Security volatility, the volatility of the Underlying Security may affect the Fund’s return as much as, or more than, the return of the Underlying Security. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security 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 Security’s return is flat. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 95% of its value, even if the cumulative 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 Security 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 Security. 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 or in “Daily Short Correlation Risk” below.
As of the date of this Prospectus, the Underlying Security has not yet traded on an exchange for a one-year calendar period and, therefore, does not have an annualized historical volatility rate or total return performance available to report. When available, historical volatility and performance are not indications of what the Underlying Security volatility and performance will be in the future. The volatility of U.S. exchange-traded securities or instruments that reflect the value of the Underlying Security may differ from the volatility of the Underlying Security.

| Risk [Text Block] | Nscale Limited Investing Risk. The Fund will be exposed to the risk that the price of Nscale Limited’s shares will increase. In addition to developments affecting the software and services industry generally, Nscale’s share price could increase as a result of growing demand for artificial intelligence computing capacity, new or expanded customer contracts, successful development of data centers, access to additional power or advanced computing equipment, strategic partnerships, acquisitions, improved operating results, favorable financing or increased investor interest in artificial intelligence infrastructure companies. Any of these developments could cause the price of Nscale’s shares to increase significantly, which would adversely affect the Fund.
Nscale has filed a registration statement relating to its proposed IPO. The timing and completion of the offering are subject to regulatory review, market conditions and other factors, and the offering may be delayed or may not be completed. If the offering is completed, the Underlying Security will have a limited public trading history upon which investors can evaluate its performance, and its market price may be volatile. The trading price of the Underlying Security may fluctuate significantly due to company-specific developments, changes in investor expectations, general market conditions, lock-up expirations for pre-IPO shareholders, changes in trading volume, the entry or exit of large shareholders or other factors unrelated to Nscale’s operating performance.

| Leverage Shares 2X Short NScale Daily ETF | Derivatives Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks. Investing in derivatives may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.
The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective.
Swap Agreements. The Fund expects to use swap agreements to achieve its investment objective. Swap agreements are entered into primarily with major global financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive regulatory protection, which may expose investors to significant losses.
Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies, national and international political and economic events, changes in the actual or implied volatility of the reference asset, and the time remaining until expiration of the option contract. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying
Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The exercise rights associated with an option depend on the terms of the particular option contract, including whether the option is American-style or European-style. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.
FLEX Options. FLEX Options are exchange-traded options contracts with uniquely customizable terms like exercise price, style, and expiration date. Due to their customization and potentially unique terms, FLEX Options may be less liquid than other securities, such as standard exchange listed options. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price.
These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

It is possible that government regulation of various types of derivative instruments, including swap agreements, may limit or prevent the Fund from using such instruments as a part of its investment strategy, and could ultimately prevent the Fund from being able to achieve its investment objective. It is impossible to predict fully the effects of legislation and regulation in this area, but the effects could be substantial and adverse.

| Risk [Text Block] | Artificial Intelligence (“AI”) Risk. Companies that rely on, develop, integrate, or provide infrastructure supporting artificial intelligence technologies face risks related to the complexity, cost, and uncertainty of AI development and deployment. AI systems may produce inaccurate, biased, unreliable, or unintended results, and may fail to perform as expected in real-world applications. The use and development of AI may be subject to heightened regulatory scrutiny, evolving legal and compliance requirements, and increased liability related to data privacy, cybersecurity, intellectual property, and ethical considerations. Significant investments in AI and related infrastructure, talent, and research may not generate anticipated returns, and rapid technological change may render existing AI technologies or supporting infrastructure obsolete or less competitive. Demand for AI-related infrastructure may not develop or be sustained at anticipated levels. In addition, increased competition from companies that develop, deploy, or support AI more effectively or at lower cost could adversely affect market position, operating results, or financial condition.

| Risk [Text Block] | Counterparty/Collateral Risk. If a counterparty is unwilling or unable to make timely payments, meet its contractual obligations or return holdings that are subject to the agreement with the counterparty, the Fund may lose money or may be unable to meet its daily leveraged investment objective.
In addition, because the Fund may enter into swap agreements with a limited number of counterparties, this increases the Fund’s exposure to counterparty credit risk. 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 leveraged investment objective or rebalance properly, which may result in significant losses to the Fund, or the Fund may decide to change its leveraged investment objective. The risk that no suitable counterparties will enter into or continue to provide swap exposure to the Fund may be increased when there is significant market volatility. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.
Collateral pledged by a counterparty may be insufficient to fully mitigate credit exposure in the event of a default. This risk may arise from declines in collateral value, limited marketability, legal or perfection issues, or challenges in enforcing security interests. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Intraday Investment Risk. The intraday performance of Fund shares traded in the secondary market will be different from the performance of the Fund when measured from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Therefore, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s stated investment objective.
If there is a significant intraday market event and/or the Underlying Security experiences a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close prior to the close of trading on the Exchange (defined below) and experience significant losses.

The issuer’s operations and financial results may be affected by economic, political or social conditions in its home country or region, including governmental intervention or geopolitical developments. Investments in foreign issuers are also subject to currency risk and may be affected by changes in exchange rates relative to the U.S. dollar. Foreign markets may have different trading, settlement and regulatory practices, which may increase operational risks.

The Fund will be concentrated in the industry to which the Underlying Security is assigned (i.e., hold more than 25% of its total assets in investments that provide short exposure to the industry to which the Underlying Security is assigned).

Software and Services Industry Risk. Companies in the software and services industry are subject to intense competition, rapid technological change, evolving industry standards and changing customer preferences. The success of these companies depends on their ability to develop, introduce and support new products and services, attract and retain skilled personnel and protect their intellectual property. Software and services companies may also be adversely affected by pricing pressures, cybersecurity incidents, changing technology spending patterns and the risk of product obsolescence.

Local, regional or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective. Global trade policies, including tariffs, could also materially adversely affect the performance of the Fund’s holdings.

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

| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), 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. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intraday (premium) or less than the NAV intraday (discount). 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. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The ability to trade certain securities or financial instruments may be restricted, which may result in a fund being unable to buy or sell certain securities or financial instruments.

As a result, the Fund may not be tax efficient and will incur brokerage and financing costs related to buying and selling securities or obtaining derivative exposure to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund will bear such costs, which will decrease the Fund’s net asset value.

| Risk [Text Block] | Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter and meet annual distribution requirements.
The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, including gaining exposure to the Underlying Security through the use of swaps, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders and were ineligible to or were not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

| Risk [Text Block] | IPO Risk. The Fund expects to commence operations on or about the same date as the Underlying Security commences trading in connection with its IPO. As a result, the Fund will seek exposure to the Underlying Security, consistent with its investment objective, during a period in which the Underlying Security has a limited trading history, limited publicly available information, uncertain market valuation and potentially significant price volatility. Trading in the Underlying Security may be subject to substantial fluctuations in price, wide bid-ask spreads, trading halts, limited liquidity, price discovery challenges and other market disruptions that are more common following an IPO. The Fund may have difficulty obtaining exposure to the Underlying Security on terms that are consistent with its investment objective, particularly during the initial days or weeks following the IPO, which may cause the Fund not to meet its investment objective during this time. In addition, options, swaps or other derivatives referencing the Underlying Security may not be immediately available, may have limited liquidity, may be more expensive than anticipated or may not provide the desired exposure. The Fund’s performance, ability to achieve its investment objective and ability to rebalance its portfolio may be adversely affected by these conditions. These risks are likely to be heightened on the first day of trading and during the period immediately following the IPO.

| Risk [Text Block] | Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that the Underlying Security’s value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the Underlying Security. Under such circumstances, the market for the Underlying Security may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of the Underlying Security and may impact the ability of the Fund to achieve its investment objective.
In certain cases, the market for the Underlying Security and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of the Underlying Security and correlated derivative instruments. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Risk [Text Block] | Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active secondary market trading of the Shares could cause more frequent creation and redemption activities, which would increase the number of portfolio transactions. High levels of portfolio transactions may cause higher transaction costs because of increased broker commissions resulting from such transactions and increased taxable capital gains. The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise most of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher. |

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Inverse Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing inverse leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize inverse leverage. An investment in the Fund is exposed to the risk that an increase in the daily performance of the Underlying Security will be magnified due to the Fund’s leveraged inverse exposure. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily increase in the Underlying Security, not including the costs of financing leverage and other operating expenses, which would further reduce its value. If the Underlying Security increases by 50% or more in a single trading day, the Fund would lose all or substantially all of its value. A total loss may occur in a single trading day even if the Underlying Security does not increase by 100% or more. This would result in a total loss of a shareholder’s investment in one day even if the Underlying Security subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if the Underlying Security does not lose all of its value. Inverse leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Underlying Security and may increase the volatility of the Fund.
To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Daily Short Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its daily inverse leveraged investment objective. The Fund’s exposure to the Underlying Security is impacted by the Underlying Security’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to the Underlying Security at the end of each day. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.
The Fund may have difficulty achieving its daily inverse leverage investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with the Underlying Security. The Fund may 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 Security. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of the Underlying Security. Any of these factors could decrease the correlation between the performance of the Fund and the Underlying Security and may hinder the Fund’s ability to meet its daily inverse leveraged investment objective on or around that day.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Shorting Risk. A short position is a financial transaction in which an investor sells an asset that the investor does not own. In such a transaction, an investor’s short position appreciates when a reference asset falls in value. By contrast, the short position loses value when the reference asset’s value increases. Because historically most assets have risen in value over the long term, short positions are expected to depreciate in value. Accordingly, short positions may be riskier and more speculative than traditional investments. In addition, any income, dividends or payments by reference assets in which the Fund has a short position will impose expenses on the Fund that reduce returns.
The Fund will obtain short exposure through the use of swap agreements and option contracts. To the extent that the Fund obtains short exposure from derivatives, the Fund may be exposed to heightened volatility or limited liquidity related to the reference asset of the underlying short position, which will adversely impact the Fund’s ability to meet its investment objective or adversely impact its performance. If the Fund were to experience this volatility or decreased liquidity, the Fund may be required to obtain short exposure through alternative investment strategies that may be less desirable or more costly to implement. If the reference asset underlying the short position is thinly traded or has a limited market, there may be a lack of available securities or counterparties for the Fund to enter into a short position or obtain short exposure from a derivative.

| Leverage Shares 1X Short NScale Daily ETF | Effects Of Compounding And Market Volatility Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk. The Fund has a daily inverse investment objective and 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 very likely to differ from -100% of the Underlying Security’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 Security during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security 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 the Underlying Security. The chart below provides examples of how volatility and its return could affect the Fund’s performance. The chart shows estimated Fund returns for a number of combinations of volatility and performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to the Underlying Security; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged short 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 volatility, compounding will cause results for periods longer than a trading day to vary from -100% of the performance of the Underlying Security.
During periods of higher Underlying Security volatility, the volatility of the Underlying Security may affect the Fund’s return as much as, or more than, the return of the Underlying Security. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
As shown in the chart below, the Fund would be expected to lose 6.04% if the Underlying Security provided no return over a one-year period during which the Underlying Security 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 Security’s return is flat. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.23% of its value, even if the cumulative 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 -100% of the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than -100% of the performance of the Underlying Security. 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 or in “Daily Short Correlation Risk” below.
As of the date of this Prospectus, the Underlying Security has not yet traded on an exchange for a one-year calendar period and, therefore, does not have an annualized historical volatility rate or total return performance available to report. When available, historical volatility and performance are not indications of what the Underlying Security volatility and performance will be in the future. The volatility of U.S. exchange-traded securities or instruments that reflect the value of the Underlying Security may differ from the volatility of the Underlying Security.

| Risk [Text Block] | Nscale Limited Investing Risk. The Fund will be exposed to the risk that the price of Nscale Limited’s ordinary shares will increase. In addition to developments affecting the software and services industry generally, Nscale’s share price could increase as a result of growing demand for artificial intelligence computing capacity, new or expanded customer contracts, successful development of data centers, access to additional power or advanced computing equipment, strategic partnerships, acquisitions, improved operating results, favorable financing or increased investor interest in artificial intelligence infrastructure companies. Any of these developments could cause the price of Nscale’s ordinary shares to increase significantly, which would adversely affect the Fund.
Nscale has filed a registration statement relating to its proposed IPO. The timing and completion of the offering are subject to regulatory review, market conditions and other factors, and the offering may be delayed or may not be completed. If the offering is completed, the Underlying Security will have a limited public trading history upon which investors can evaluate its performance, and its market price may be volatile. The trading price of the Underlying Security may fluctuate significantly due to company-specific developments, changes in investor expectations, general market conditions, lock-up expirations for pre-IPO shareholders, changes in trading volume, the entry or exit of large shareholders or other factors unrelated to Nscale’s operating performance.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks. Investing in derivatives may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.
The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective.
Swap Agreements. The Fund expects to use swap agreements to achieve its investment objective. Swap agreements are entered into primarily with major global financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive regulatory protection, which may expose investors to significant losses.
Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies, national and international political and economic events, changes in the actual or implied volatility of the reference asset, and the time remaining until expiration of the option contract. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. Depending on their terms and exercise style, options held by a Fund may be exercisable at expiration or at any time prior to expiration. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.
FLEX Options. FLEX Options are exchange-traded options contracts with uniquely customizable terms like exercise price, style, and expiration date. Due to their customization and potentially unique terms, FLEX Options may be less liquid than other securities, such as standard exchange listed options. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price.
These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Risk [Text Block] | Government Regulation of Derivatives Risk. It is possible that government regulation of various types of derivative instruments, including swap agreements, may limit or prevent the Fund from using such instruments as a part of its investment strategy, and could ultimately prevent the Fund from being able to achieve its investment objective. It is impossible to predict fully the effects of legislation and regulation in this area, but the effects could be substantial and adverse.

| Risk [Text Block] | Artificial Intelligence (“AI”) Risk. Companies that rely on, develop, integrate, or provide infrastructure supporting artificial intelligence technologies face risks related to the complexity, cost, and uncertainty of AI development and deployment. AI systems may produce inaccurate, biased, unreliable, or unintended results, and may fail to perform as expected in real-world applications. The use and development of AI may be subject to heightened regulatory scrutiny, evolving legal and compliance requirements, and increased liability related to data privacy, cybersecurity, intellectual property, and ethical considerations. Significant investments in AI and related infrastructure, talent, and research may not generate anticipated returns, and rapid technological change may render existing AI technologies or supporting infrastructure obsolete or less competitive. Demand for AI-related infrastructure may not develop or be sustained at anticipated levels. In addition, increased competition from companies that develop, deploy, or support AI more effectively or at lower cost could adversely affect market position, operating results, or financial condition.

| Risk [Text Block] | Counterparty/Collateral Risk. If a counterparty is unwilling or unable to make timely payments, meet its contractual obligations or return holdings that are subject to the agreement with the counterparty, the Fund may lose money or may be unable to meet its daily leveraged investment objective.
In addition, because the Fund may enter into swap agreements with a limited number of counterparties, this increases the Fund’s exposure to counterparty credit risk. 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 leveraged investment objective or rebalance properly, which may result in significant losses to the Fund, or the Fund may decide to change its leveraged investment objective. The risk that no suitable counterparties will enter into or continue to provide swap exposure to the Fund may be increased when there is significant market volatility.
Collateral pledged by a counterparty may be insufficient to fully mitigate credit exposure in the event of a default. This risk may arise from declines in collateral value, limited marketability, legal or perfection issues, or challenges in enforcing security interests. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Intraday Investment Risk. The intraday performance of Fund shares traded in the secondary market will be different from the performance of the Fund when measured from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Therefore, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s stated investment objective.
If there is a significant intraday market event and/or the Underlying Security experiences a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close prior to the close of trading on the Exchange (defined below) and experience significant losses.

Foreign securities may be more volatile and less liquid than U.S. securities, and the issuer may be subject to different accounting, auditing, financial reporting and disclosure standards, which may result in less publicly available information. The issuer’s operations and financial results may be affected by economic, political or social conditions in its home country or region, including governmental intervention or geopolitical developments. Investments in foreign issuers are also subject to currency risk and may be affected by changes in exchange rates relative to the U.S. dollar. Foreign markets may have different trading, settlement and regulatory practices, which may increase operational risks.

| Risk [Text Block] | Concentration Risk. The Fund will be concentrated in the industry to which the Underlying Security is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which the Underlying Security is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio that is broadly diversified over several industries or sectors. As of the date of this prospectus, the Underlying Security is expected to be assigned to the software and services industry.
Software and Services Industry Risk. Companies in the software and services industry are subject to intense competition, rapid technological change, evolving industry standards and changing customer preferences. The success of these companies depends on their ability to develop, introduce and support new products and services, attract and retain skilled personnel and protect their intellectual property. Software and services companies may also be adversely affected by pricing pressures, cybersecurity incidents, changing technology spending patterns and the risk of product obsolescence.

The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

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

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), 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. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intraday (premium) or less than the NAV intraday (discount). 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. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The ability to trade certain securities or financial instruments may be restricted, which may result in a fund being unable to buy or sell certain securities or financial instruments. In these circumstances, a fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Risk [Text Block] | Cash Transaction Risk. The Fund will generally effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and will incur brokerage and financing costs related to buying and selling securities or obtaining derivative exposure to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund will bear such costs, which will decrease the Fund’s net asset value.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter and meet annual distribution requirements.
The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, including gaining exposure to the Underlying Security through the use of swaps, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders and were ineligible to or were not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

| Risk [Text Block] | IPO Risk. The Fund expects to commence operations on or about the same date as the Underlying Security commences trading in connection with its IPO. As a result, the Fund will seek exposure to the Underlying Security, consistent with its investment objective, during a period in which the Underlying Security has a limited trading history, limited publicly available information, uncertain market valuation and potentially significant price volatility. Trading in the Underlying Security may be subject to substantial fluctuations in price, wide bid-ask spreads, trading halts, limited liquidity, price discovery challenges and other market disruptions that are more common following an IPO. The Fund may have difficulty obtaining exposure to the Underlying Security on terms that are consistent with its investment objective, particularly during the initial days or weeks following the IPO, which may cause the Fund not to meet its investment objective during this time. In addition, options, swaps or other derivatives referencing the Underlying Security may not be immediately available, may have limited liquidity, may be more expensive than anticipated or may not provide the desired exposure. The Fund’s performance, ability to achieve its investment objective and ability to rebalance its portfolio may be adversely affected by these conditions. These risks are likely to be heightened on the first day of trading and during the period immediately following the IPO.

| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

| Risk [Text Block] | Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that the Underlying Security’s value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the Underlying Security. Under such circumstances, the market for the Underlying Security may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of the Underlying Security and may impact the ability of the Fund to achieve its investment objective.
In certain cases, the market for the Underlying Security and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of the Underlying Security and correlated derivative instruments. These risks are expected to be heightened during the period immediately following the Underlying Security’s IPO.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active secondary market trading of the Shares could cause more frequent creation and redemption activities, which would increase the number of portfolio transactions. High levels of portfolio transactions may cause higher transaction costs because of increased broker commissions resulting from such transactions and increased taxable capital gains. The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise most of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher. |

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Daily Short Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its daily inverse investment objective. The Fund’s exposure to the Underlying Security is impacted by the Underlying Security’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to the Underlying Security at the end of each day. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.
The Fund may have difficulty achieving its daily inverse investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with the Underlying Security. The Fund may 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 Security. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of the Underlying Security. Any of these factors could decrease the correlation between the performance of the Fund and the Underlying Security and may hinder the Fund’s ability to meet its daily inverse investment objective on or around that day.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Shorting Risk. A short position is a financial transaction in which an investor sells an asset that the investor does not own. In such a transaction, an investor’s short position appreciates when a reference asset falls in value. By contrast, the short position loses value when the reference asset’s value increases. Because historically most assets have risen in value over the long term, short positions are expected to depreciate in value. Accordingly, short positions may be riskier and more speculative than traditional investments. In addition, any income, dividends or payments by reference assets in which the Fund has a short position will impose expenses on the Fund that reduce returns.
The Fund will obtain short exposure through the use of swap agreements and option contracts. To the extent that the Fund obtains short exposure from derivatives, the Fund may be exposed to heightened volatility or limited liquidity related to the reference asset of the underlying short position, which will adversely impact the Fund’s ability to meet its investment objective or adversely impact its performance. If the Fund were to experience this volatility or decreased liquidity, the Fund may be required to obtain short exposure through alternative investment strategies that may be less desirable or more costly to implement. If the reference asset underlying the short position is thinly traded or has a limited market, there may be a lack of available securities or counterparties for the Fund to enter into a short position or obtain short exposure from a derivative.

| Risk [Text Block] | Inverse Exposure Risk. The Fund seeks to provide inverse (-100%) exposure to the daily performance of the Underlying Security and is subject to the risk that increases in the price of the Underlying Security will result in losses, which may be significant and occur rapidly. Because the Fund’s exposure is reset on a daily basis, the Fund’s performance for periods longer than one day will be the result of the compounding of daily returns and will likely differ, and may differ significantly, from the inverse of the return of the Underlying Security for the same period. A relatively small increase in the price of the Underlying Security may result in a corresponding decrease in the value of the Fund, and the Fund could lose a substantial portion or all of its value in a single trading day if the Underlying Security experiences a significant increase. The Fund’s use of derivatives to obtain inverse exposure may magnify any lack of correlation between the Fund’s performance and that of the Underlying Security and may increase the volatility of the Fund. In addition, the Fund’s ability to achieve its investment objective depends on the availability of suitable derivative instruments and counterparties; if such instruments are unavailable or become illiquid, the Fund may be unable to obtain the desired exposure, which could adversely affect its ability to meet its investment objective, impair its ability to issue additional Creation Units, and cause its shares to trade at a premium or discount to net asset value and/or experience wider bid-ask spreads.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | The Fund is considered to be non-diversified. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
