Shorting or Inverse Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Shorting or Inverse Risk – The Fund will lose money when the value of PDD rises because of the Fund’s inverse or short exposure – this result is the opposite from a traditional index fund. The Fund’s assets will increase in value when PDD’s daily return decreases. The Fund’s assets will decrease in value when PDD’s daily return increases. Because historically most assets have risen in value over the long term, short exposure or positions and therefore, the value of the Fund is expected to depreciate in value over time, notwithstanding any separate effects of compounding and the Fund’s daily repositioning of inverse exposure. Additionally, if the level of PDD approaches a 100% increase at any point in the day, an investor could lose their entire investment. Accordingly, short positions and exposure may be riskier and more speculative than traditional investments. The costs of obtaining short exposure or maintaining short positions will lower the Fund’s returns. To the extent that the Fund obtains short exposure from derivatives, the Fund may be exposed to heightened volatility, reduced correlation to PDD 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 have less correlation to PDD, less liquidity or are 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 instrument.
Effects of Compounding and Market Volatility Risk [Member]

Risk [Text Block] Effects of Compounding and Market Volatility Risk
The Fund’s performance for periods greater than a trading day will be the result of each day's returns compounded over the period, which is likely to differ from -100% of PDD’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse 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 PDD during the shareholder’s holding period. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) volatility; b) performance; c) period of time; d) financing rates associated with inverse exposure; e) other Fund expenses; and f) dividends or interest paid with respect to securities of PDD. 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. Actual Fund returns are expected to vary from these estimates. Performance shown in the chart assumes that: (i) no dividends were paid with respect to the securities; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain inverse 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 PDD. As shown in the chart below, the Fund would be expected to lose 6.04% if PDD provided no return over a one year period during which PDD 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 PDD’s return is flat. For instance, if PDD’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 PDD 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 PDD. 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 Inverse Correlation Risk” below.One Year-100%OneYearVolatility RateReturnReturn10%25%50%75%100%-60%60%148.55%134.42%95.28%43.98%-5.83%-50%50%99.13%87.77%56.26%15.23%-24.77%-40%40%66.08%56.57%30.21%-4.08%-37.57%-30%30%42.43%34.25%11.56%-17.98%-46.76%-20%20%24.67%17.47%-2.47%-28.38%-53.72%-10%10%10.83%4.44%-13.28%-36.52%-58.79%0%0%-0.25%-6.04%-22.08%-42.90%-63.23%10%-10%-9.32%-14.64%-29.23%-48.27%-66.67%20%-20%-16.89%-21.75%-35.24%-52.72%-69.67%30%-30%-23.29%-27.84%-40.25%-56.41%-71.94%40%-40%-28.78%-33.01%-44.63%-59.81%-74.32%50%-50%-33.55%-37.52%-48.57%-62.60%-76.19%60%-60%-37.72%-41.51%-51.96%-65.19%-78.12%PDD’s annualized historical volatility rate for the five year period ended December 31, 2025 was 70.16%. PDD’s highest volatility rate for any one calendar year during the five year period was 103.25% and volatility for a shorter period of time may have been substantially higher. PDD’s annualized performance for the five-year period ended December 31, 2025 was -8.59%. Historical volatility and performance are not indications of what PDD volatility and performance will be in the future.For information regarding the effects of volatility and performance on the long-term performance of the Fund, see “Additional Information Regarding Investment Techniques and Policies” in the Fund’s statutory prospectus, and "Leverage - Special Note Regarding the Correlation Risks of the Funds" in the Fund’s Statement of Additional Information under “Investment Policies and Techniques.”
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, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or smaller 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 investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation and legal restrictions. The performance of a derivative may not track the performance of its reference asset for various reasons, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. If the underlying security has a dramatic intraday increase or decrease that causes a material change in the Fund’s performance and/or net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close the swap agreement with the Fund. In that event, the Fund may not be able to enter into another swap agreement or invest in other derivatives to achieve its investment objective. This may occur even if the underlying security reverses all or a portion of its intraday movement by the end of the day. Upon entering into certain derivatives contracts, such as swap agreements, and to maintain open positions in such agreements, the Fund may be required to post collateral, the amount of which may vary. As such, the Fund may maintain cash balances, which may be significant, with service providers such as the Fund’s custodian or its affiliates in segregated accounts. Maintaining larger cash and cash equivalent positions may also subject the Fund to additional risks, such as increased credit risk with respect to the custodian bank holding the assets.
Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Counterparty Risk If a counterparty is unwilling or unable to make timely payments to meet its contractual obligations or fails to return holdings that are subject to the agreement with the counterparty, the Fund will lose money and/or not be able to meet its daily inverse investment objective. 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 inverse investment objective or rebalance properly, which may result in significant losses to the Fund. The risk that no suitable counterparties will enter into or continue to provide swap exposure to the Fund may be heightened when there is significant volatility in the overall market or the reference asset.
Rebalancing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Rebalancing Risk If for any reason the Fund is unable to rebalance all or a part 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 its investment objective which may lead to greater losses or reduced gains. In these instances, the Fund may have investment exposure to PDD that is significantly greater or significantly less than its stated investment objective. Additionally, the Fund may close to purchases and sales of Shares prior to the close of trading on the Nasdaq or other national securities listing exchanges where Shares are listed and incur significant losses.
Cash Transaction Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Cash Transaction Risk Unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally for in-kind securities, because of the nature of the financial instruments held by the Fund. As a result, the Fund is not expected to be tax efficient and will incur brokerage and financing costs related to buying and selling securities and/or obtaining short derivative exposure to achieve its investment objective thus incurring additional expenses than other funds that primarily effect creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.
Intra Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Intra-Day Investment Risk— The intra-day 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. An investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated investment objective. If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective or may be unable to rebalance its portfolio appropriately, resulting in significant losses or reduced gains. In response to significant intraday market volatility, among other actions, the Adviser may determine to trade a portion or all of the rebalance trade for the Fund prior to market close, which may result in the Fund not achieving its investment objective. Additionally, the Fund’s Shares traded on the secondary market may experience significant premiums or discounts, or widened bid-ask spreads.
Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Daily Inverse Correlation Risk - There is no guarantee that the Fund will achieve a high degree of inverse correlation to PDD and therefore achieve its daily inverse investment objective. The Fund’s exposure to PDD is impacted by PDD’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to PDD at the end of each day. The possibility of the Fund being materially over- or under-exposed to PDD increases on days when PDD 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) PDD. The Fund may be required to trade more frequently or may refrain from taking certain positions to ensure compliance with regulatory restrictions or to ensure qualification as a registered investment company or to improve tax efficiency, or for other reasons, each of which may negatively impact the Fund’s desired inverse correlation with PDD or increase its required distributions. The derivative instruments or other investments the Fund utilizes to obtain exposure may not provide the expected correlation to PDD, resulting in the Fund not performing as expected. 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 PDD. Any of these factors could decrease the inverse correlation between the performance of the Fund and PDD and may hinder the Fund’s ability to meet its daily inverse investment objective on or around that day.
Market Risk [Member]  
Prospectus [Line Items]  
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, geopolitical events, tariffs, trade wars, natural disasters, and public health risks. Interest rates and inflation rates may change frequently and drastically due to various factors and the Fund’s investments may be adversely impacted. The economic, fiscal, monetary and foreign policies of the U.S. government, including the imposition of tariffs, changes to its federal agencies and changes to regulatory policies, will impact the U.S. economy and could lead to increased market volatility and may adversely impact the overall market and individual securities.
NonAffiliation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Affiliation Risk PDD Holdings Inc. is not affiliated with the Trust, the Adviser or any affiliates 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 PDD and make no representation as to the performance of PDD. Investing in the Fund is not equivalent to investing in PDD. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to PDD.
Security Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Security Volatility Risk The performance of the Fund is designed to correlate to the inverse performance of PDD. Significant short-term price movements in PDD could adversely impact the performance of both PDD and the Fund, increase the Fund’s bid-ask spread and adversely impact the Fund’s ability to achieve its investment objective. In addition, the net asset value of the Fund over short-term periods may be more volatile than other investment options due to the volatility of PDD.
Chinese Securities Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block] Chinese Securities Risks Although the economy of the People’s Republic of China (“China” or the “PRC”) has been in a state of transition from a government-planned socialist economy to a more market-oriented economy since the 1970s, the level of government involvement in China’s economy continues to distinguish it from other global markets as the majority of productive assets in China are owned (at different levels) by the PRC. Due to PRC government economic reforms during the last thirty years, China’s economy, as reflected in the value of Chinese issuers, has experienced significant growth. There can be no assurance, however, that the PRC government will continue to pursue such reforms. In the Chinese securities markets, a small number of issuers may represent a large portion of the entire market. The Chinese securities markets are subject to more frequent trading halts, low trading volume and price volatility. In addition, in recent years, Chinese entities have incurred significant levels of debt and Chinese financial institutions currently hold relatively large amounts of non-performing debt. Thus, there exists a possibility that widespread defaults could occur, which could trigger a financial crisis, freeze Chinese debt and finance markets and make Chinese securities illiquid. Laws and regulations in China are less well-developed and may not be enforced, and court decisions do not establish binding precedent. In addition, laws and regulations may change with little or no advance notice. Accordingly, there is little assurance about the effect of laws and regulations, including those regarding foreign investment in Chinese securities. The PRC government strictly regulates foreign currency transactions, effectively controlling the flow of capital into and out of China. The Chinese authorities can intervene in the operations and structure of Chinese companies. The Chinese economy is export-driven and highly reliant on trade. China’s maintenance of relationships with its primary trading partners, such as the U.S., Japan, South Korea and countries in the European Union, is critical to the Chinese economy. Worsening trade, diplomatic and military relations between the U.S. and China could adversely impact Chinese securities, particularly to the extent that the Chinese government restricts foreign investments in on-shore Chinese companies or the U.S. government restricts investments by U.S. investors in China or investments in Chinese securities listed on U.S. stock exchanges. Securities of Chinese companies traded on U.S. stock exchanges also may be delisted in response to changing economic sanctions, foreign investment rules or other rules, regulations or determinations by the U.S. government. Worsening trade relations may also result in market volatility and volatility in the price of Fund shares. Reduction in spending on Chinese products and services, supply chain diversification, additional tariffs or other trade barriers, an economic slowdown or recession in countries that import significant goods from China would likely adversely impact Chinese issuers. Inflation has historically been an issue in China, and the taxation of investments in China remains unsettled. Chinese issuers and the Fund, as an investor in such issuers, could be subject to retroactive taxation. There also remains a risk that assets or investments in China will be nationalized or expropriated. China’s securities markets can be more volatile than other global markets and issuers in them are not typically required to provide the same amount or quality of information, including financial information, as U.S. companies. Investors who are harmed as a result of the lack of (quality) information about Chinese issuers will generally have little to no recourse due to the lack of remedies available in China, and the difficulty of pursuing and enforcing remedies. China has experienced security concerns, such as terrorism and strained international relations. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. Additionally, China is alleged to have participated in cyberattacks against foreign countries and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on Chinese government or Chinese companies, may impact China’s economy and cause uncertainty in Chinese securities markets.
American Depositary Receipt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] American Depositary Receipt (“ADRs”) Risk ADRs are an equity security issued by a U.S. bank or broker that represents one or more shares of a foreign-company stock held by the U.S. bank in the foreign company’s home stock market. ADRs may be listed on a major U.S. stock exchange or may be traded over the counter and are generally denominated in U.S. dollars. Because ADRs are issued by non-U.S. companies, they are subject to various foreign investment risks. These risks include the risk that the currency in the issuing company’s country will drop relative to the U.S. dollar, that politics or regime changes in the issuing company’s country will undermine exchange rates or destabilize the company and its earnings, or that inflation in the issuing company’s country will erode the value of the foreign currency. Additionally, investors may not have access to the same amount of information about the company that is available about domestic companies.
Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Concentration Risk The Fund will be concentrated in a particular security, PDD, and therefore, a particular industry and will have more than 25% of its total assets in investments that provide inverse exposure to the consumer discretionary sector and retail industry (the risks of which are described below), the same industry and/or sector to which PDD is assigned. Since the Fund is concentrated in a particular security and therefore industry and/or sector, it presents more risks than a portfolio broadly diversified over several industries. A portfolio invested in multiple securities and industries typically presents less risk than a portfolio concentrated in one security or industry because market changes that adversely impact one security or industry may benefit others. Because the Fund only invests in instruments referencing one security and industry, it should be expected to increase from any market movements that adversely impact PDD and/or consumer discretionary sector and retail industry.
Consumer Discretionary Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Consumer Discretionary Sector Risk Because companies in the consumer discretionary sector manufacture products and provide discretionary services directly to the consumer, the success of these companies is tied closely to the performance of the overall domestic and international economy, including the functioning of the global supply chain, interest rates, and inflation competition and consumer confidence. Success depends heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. Also, companies in the consumer discretionary sector may be subject to intense competition, which may have an adverse impact on a company’s profitability. Changes in demographics and consumer tastes also can affect the demand for, and success of, consumer discretionary products in the marketplace.
Retail Industry Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Retail Industry Risk - Retail and related industries can be significantly affected by the performance of the domestic and international economy, consumer confidence and spending, intense competition, changes in demographics, and changing consumer tastes and preferences. In addition, the retail industry is highly competitive and a company’s success can be tied to its ability to anticipate changing consumer tastes.
Large Capitalization Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Capitalization Company Risk Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.
Money Market Instrument Risk [Member]  
Prospectus [Line Items]  
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, depositary 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. Money market instruments may lose money.
Liquidity Risk [Member]  
Prospectus [Line Items]  
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. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. 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 its investment objective. In certain market conditions the Fund may be one of many market participants that is 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 illiquidity and price volatility. 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 be unable to rebalance its exposure properly which may result in significantly more or less exposure and losses to the Fund. In such an instance, the Fund may increase its transaction fee, utilize derivatives instruments that are less correlated to PDD, change its investment objective, reduce its exposure for a period of time or close.
Early Close Trading Halt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Early Close/Trading Halt Risk An exchange or market may close early and unexpectedly or issue trading halts on specific securities or financial instruments. Under such circumstances, the Fund may be unable to execute intended portfolio transactions, rebalance its portfolio, or accurately price its investments, and may disrupt the Fund’s creation/redemption process which means the Fund may be unable to achieve its investment objective and it may incur substantial losses or reduced gains.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
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.
Tax Risk [Member]  
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, 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. Please see the section entitled “Dividends, Other Distributions and Taxes” in the Statement of Additional Information for more information.
NonDiversification Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Diversification Risk The Fund 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, the credit of a single counterparty, and/or a single economic, political or regulatory event.
Authorized Participants Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Authorized Participants Concentration Risk. The Fund may have a limited number of financial institutions that may act as Authorized Participants. To the extent that those Authorized Participants exit the business or are unable to process creation and/or redemption orders, Shares may trade at larger bid-ask spreads and/or premiums or discounts to net asset value. Authorized Participant concentration risk may be heightened for a fund that invests in non-U.S. securities or other securities or instruments that have lower trading volumes.
Absence of Active Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Absence of Active Market Risk. Although Shares are listed for trading on a stock exchange, there is no assurance that an active trading market for them will develop or be maintained. In the absence of an active trading market for Shares, they will likely trade with a wider bid/ask spread and at a greater premium or discount to net asset value.
Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Price Variance Risk. Fund Shares can be bought and sold in the secondary market at market prices, which may be higher or lower than the net asset value of the Fund. When Shares trade at a price greater than net asset value, they are said to trade at a “premium.” When they trade at a price less than net asset value, they are said to trade at a “discount.” The market price of Shares fluctuates based on changes in the value of the Fund’s holdings, the supply and demand for Shares and other market factors. The market price of Shares may vary significantly from the Fund’s net asset value especially during times of market volatility or stress. Further, to the extent that exchange specialists, market makers, Authorized Participants, or other market participants are unavailable or unable to trade the Fund’s Shares and/or create or redeem Creation Units premiums or discounts may increase.
Trading Cost Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Trading Cost Risk. When buying or selling Shares in the secondary market, a buyer may incur brokerage commission or other charges. In addition, a buyer may incur the cost of the “spread” also known as the bid-ask spread, which is the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The bid-ask spread varies over time based on, among other things, trading volume, market liquidity and market volatility. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results.
Exchange Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Exchange Trading Risk. Shares are listed for trading on the Nasdaq. They also may be listed or traded on other U.S. and non-U.S. stock exchanges and may trade on electronic communication networks. Trading in Shares on their listing exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in Shares inadvisable, including if they fail to meet the listing requirements of the exchange. Under certain circumstances, Shares may even be delisted. Trading halts of Shares should be expected to disrupt the Fund’s creation/redemption process and may temporarily prevent investors from buying and selling Shares. Like other listed securities, Shares of the Fund may be sold short, and short positions in Shares may place downward pressure on their market price.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] The Fund may not achieve its inverse investment objective and there is a risk that you could lose all of your money invested in the Fund.
