AMD Risks. The Fund invests in derivative instruments that are based on the value of AMD. This subjects the Fund to certain of the same risks as if it owned shares of AMD, even though it does not. By virtue of the Fund’s investments in derivative instruments that are based on the value of AMD, the Fund may also be subject to the following risks:

Indirect Investment in AMD Risk. AMD is not affiliated with the Trust, the Fund, the Adviser, or their respective affiliates and is not involved with this offering in any way and has no obligation to consider your Shares in taking any corporate actions that might affect the value of Shares. Investors in the Fund will not have voting rights and will not be able to influence the management of AMD but will be exposed to the performance of AMD (the underlying stock). Investors in the Fund will not have rights to receive dividends or other distributions or any other rights with respect to the underlying stock but will be subject to declines in the performance of the underlying stock.

AMD Trading Risk. The trading price of AMD may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of AMD may be traded by short sellers which may put pressure on the supply and demand for the common stock of AMD, further influencing volatility in its market price. Public perception and other factors outside of the control of AMD may additionally impact AMD’s stock price due to AMD garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against AMD in the past. While AMD continues to defend such actions, any judgment against AMD, or any future stockholder litigation could result in substantial costs and a diversion of the management of AMD’s attention and resources. If AMD trading is halted, trading in Shares of the AMD Fund may be impacted, either temporarily or indefinitely.

AMD Performance Risk. AMD may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of AMD to decline. AMD provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance AMD provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If AMD’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by AMD could decline significantly.

Risk [Text Block]

Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

Risk [Text Block]

Competition Risk. The markets in which AMD’s products are sold are highly competitive and rapidly evolving. AMD expects that competition will continue to be intense due to rapid technological changes, new and evolving industry standards, changing customer preferences and requirements, and frequent introductions by competitors of products that may provide better performance/experience or that may include additional features that render AMD’s products comparatively less competitive. In addition, Intel Corporation’s dominance of the microprocessor market and its aggressive business practices may limit AMD’s ability to compete effectively on a level playing field. In addition, NVIDIA Corporation’s Data Center GPU market share position, significant financial resources, introduction of competitive new products and proprietary software ecosystem have enabled it to market and price its products in a manner to encourage the selection of NVIDIA-based systems and to influence customers who do business with AMD.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Distribution Risk. As part of the Fund’s investment objective, the Fund seeks to provide current income twice weekly. There is no assurance that the Fund will make more than one, or any, distribution in a given week. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next.

 

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | NAV Erosion Risk Due to Distributions [Member]  
Prospectus [Line Items]  
Risk [Text Block]

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Equity Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund’s investment exposure will be concentrated in (or substantially exposed to) the same industry or group of industries assigned to the Underlying Security. As a result, the Fund may be more susceptible to loss due to adverse occurrences that affect the price of such industries more than the market as a whole.

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Costs of Buying or Selling Shares [Member]

Risk [Text Block]

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Trading [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Risk [Text Block]

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline.

Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

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. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

Defiance AdvMicrDev LightningSpread(TM) Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Distribution Risk. As part of the Fund’s investment objective, the Fund seeks to provide current income twice weekly. There is no assurance that the Fund will make more than one, or any, distribution in a given week. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

AAPL Trading Risk. The trading price of AAPL may be volatile and subject to significant fluctuations in response to a variety of factors, many of which are beyond Apple Inc.’s control. The broader equity markets, and particularly those for large technology companies, have experienced substantial price and volume volatility that is often disproportionate to changes in operating performance. Factors such as shifts in consumer demand, supply chain disruptions, macroeconomic conditions, or changes in investor sentiment toward the technology sector may cause AAPL’s trading price to vary significantly. Public perception and media attention surrounding Apple Inc., its products, and its leadership can also affect market valuation independent of financial results. Furthermore, following periods of stock price volatility, securities class action litigation has often been brought against public companies, including Apple Inc. Any such proceedings could result in significant legal costs, potential liabilities, and diversion of management attention, which may adversely affect Apple Inc.’s operations and financial condition.

Apple Inc. Performance Risk. Apple Inc. may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of AAPL to decline. Apple Inc. provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance Apple Inc. provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If Apple Inc.’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by Apple Inc. could decline significantly.

Prospectus [Line Items]  
Risk [Text Block]

Technology Industry Risk. The technology industry, including, in some instances, Apple Inc., is subject to intense media, political and regulatory scrutiny, which may expose Apple Inc. to increasing regulation, government investigations, legal actions and penalties.

 

From time to time, Apple Inc. has made changes to its App Store, including actions taken in response to competition, market and legal conditions. Apple Inc. may make further business changes in the future. New legislative initiatives, such as the proposed EU Digital Markets Act, could, if enacted, require further changes. These changes could include how and to what extent Apple Inc. charges developers for access to its platforms and manages distribution of apps outside of the App Store.

 

Apple Inc. is also currently subject to antitrust investigations in various jurisdictions around the world, which can result in legal proceedings and claims against Apple Inc. that could, individually or in the aggregate, have a materially adverse impact on Apple Inc.’s business, results of operations and financial condition. For example, Apple Inc. is the subject of investigations in Europe and other jurisdictions relating to App Store terms and conditions. If such investigations result in adverse findings against Apple Inc., it could be exposed to significant fines and may be required to make changes to its App Store business, all of which could materially adversely affect Apple Inc.’s business, results of operations and financial condition. Apple Inc. is also subject to litigation relating to the App Store, which has resulted in changes to Apple Inc.’s business practices, and may in the future result in further changes.

 

Further, Apple Inc. has commercial relationships with other companies in the technology industry that are or may become subject to investigations and litigation that, if resolved against those other companies, could adversely affect Apple Inc.’s commercial relationships with those business partners and materially adversely affect Apple Inc.’s business, results of operations and financial condition. For example, Apple Inc. earns revenue from licensing arrangements with other companies to offer their search services on Apple Inc.’s platforms and apps, and certain of these arrangements are currently subject to government investigations and legal proceedings.

 

There can be no assurance Apple Inc.’s business will not be materially adversely affected, individually or in the aggregate, by the outcomes of such investigations, litigation or changes to laws and regulations in the future. Changes to Apple Inc.’s business practices to comply with new laws and regulations or in connection with other legal proceedings could negatively impact the reputation of Apple Inc.’s products for privacy and security and otherwise adversely affect the experience for users of Apple Inc.’s products and services, and result in harm to Apple Inc.’s reputation, loss of competitive advantage, poor market acceptance, reduced demand for products and services, and lost sales.

Global Events Risk. Apple Inc.’s business can be impacted by political events, trade and other international disputes, war, terrorism, natural disasters, public health issues, industrial accidents and other business interruptions. Political events, trade and other international disputes, war, terrorism, natural disasters, public health issues, industrial accidents and other business interruptions can harm or disrupt international commerce and the global economy, and could have a material adverse effect on Apple Inc. and its customers, suppliers, contract manufacturers, logistics providers, distributors, cellular network carriers and other channel partners.

 

 

Apple Inc. has a large, global business with sales outside the U.S. representing a majority of Apple Inc.’s total net sales, and Apple Inc. believes that it generally benefits from growth in international trade. Substantially all of Apple Inc.’s manufacturing is performed in whole or in part by outsourcing partners located primarily in Asia, including China mainland, India, Japan, South Korea, Taiwan and Vietnam. Trade policies and disputes and other international conflicts can result in tariffs, sanctions and other measures that restrict international trade, and can materially adversely affect Apple Inc.’s business, particularly if these measures occur in regions where Apple Inc. derives a significant portion of its revenues and/or has significant supply chain operations. For example, tensions between the U.S. and China have led to a series of tariffs being imposed by the U.S. on imports from China mainland, as well as other business restrictions. Tariffs increase the cost of Apple Inc.’s products and the components and raw materials that go into making them. These increased costs can adversely impact the gross margin that Apple Inc. earns on its products. Tariffs can also make Apple Inc.’s products more expensive for customers, which could make Apple Inc.’s products less competitive and reduce consumer demand. Countries may also adopt other measures, such as controls on imports or exports of goods, technology or data, that could adversely impact Apple Inc.’s operations and supply chain and limit Apple Inc.’s ability to offer its products and services as designed. These measures can require Apple Inc. to take various actions, including changing suppliers, restructuring business relationships, and ceasing to offer third-party applications on its platforms. Changing Apple Inc.’s operations in accordance with new or changed trade restrictions can be expensive, time-consuming and disruptive to Apple Inc.’s operations. Such restrictions can be announced with little or no advance notice and Apple Inc. may not be able to effectively mitigate all adverse impacts from such measures. If disputes and conflicts further escalate in the future, actions by governments in response could be significantly more severe and restrictive and could materially adversely affect Apple Inc.’s business. Political uncertainty surrounding trade and other international disputes could also have a negative effect on consumer confidence and spending, which could adversely affect Apple Inc.’s business.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance Blkstne LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Blkstne LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance Blkstne LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.

In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned.

BX Trading Risk. BX may be volatile and subject to significant fluctuations in response to a variety of factors, many of which are beyond BX’s control. These factors include variations in operating results, changes in market conditions affecting the asset-management industry, fluctuations in interest rates, and changes in investor sentiment regarding the alternative-investment sector. Broader stock market volatility may also affect BX’s trading price, and such fluctuations may be disproportionate to changes in Blackstone Inc.’s operating performance. Public perception of Blackstone Inc., the alternative-asset-management industry, or the broader financial markets may further influence the market price of BX. Periods of market stress or negative publicity can adversely affect investor confidence and trading dynamics. In addition, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against issuers. Blackstone has, from time to time, been subject to stockholder litigation and may be involved in such actions in the future. Any adverse judgments, settlements, or costs associated with these proceedings could have a material effect on BX’s financial condition or divert management’s attention from business operations.

Blackstone Inc. Performance Risk. The financial performance and market price of BX depend on its ability to meet investor and analyst expectations. Blackstone Inc. may from time to time provide forward-looking information regarding anticipated fundraising, investment performance, or earnings, all of which involve inherent uncertainty. These expectations rely on assumptions about economic conditions, market performance, and other factors largely outside of Blackstone Inc.’s control. Adverse market developments, reduced investment performance, or slower capital deployment could cause results to differ materially from expectations and negatively affect investor confidence. If Blackstone Inc. fails to achieve projected financial or strategic objectives, or if actual results fall short of market expectations, the trading price of BX could decline significantly.

Fundraising and Realization Risk. Blackstone Inc.’s asset-management model relies heavily on its ability to raise new third-party capital, deploy it in attractive investments, and realize those investments at favorable valuations. A slowdown in fundraising, or deterioration in the performance of its funds and underlying assets, could reduce management fee revenue, impair performance fee (“carry”) recognition and may even necessitate the repayment of already-paid performance allocations. Moreover, the valuations of private assets and funds are inherently subjective and may not be realized in the market; if actual exit values or timing diverge from expectations, Blackstone Inc.’s financial results and investor returns may suffer.

Extensive regulation may impede Blackstone Inc.’s ability to deploy capital, monetize investments or operate certain businesses. In addition, given Blackstone Inc.’s scale and the breadth of its business lines, conflicts of interest may arise (for example, in the allocation of investment opportunities among funds and vehicles, or in transactions between affiliated or side-by-side vehicles). The management of such conflicts is critical and the failure to do so effectively could impair investor confidence, may lead to reputational damage, and could result in adverse investor or regulatory actions.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance CRCL LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance CRCL LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance CRCL LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

CRCL Trading Risk. The trading price of CRCL may be subject to volatility and could experience wide fluctuations due to various factors. Short sellers may also play a significant role in trading CRCL, potentially affecting the supply and demand dynamics and contributing to market price volatility. Public perception and external factors beyond the company’s control may influence CRCL’s stock price disproportionately. Additionally, following periods of market volatility, companies have faced securities class action litigation. Any adverse judgment or future stockholder litigation could result in substantial costs and divert management’s attention and resources. In the event of a halt in trading of CRCL, trading in shares of related funds may be impacted, either temporarily or indefinitely.

Circle Performance Risk. Circle may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of CRCL to decline. Circle provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance Circle provides may not ultimately be accurate. If Circle’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of CRCL could decline significantly.

 

Defiance CRCL LightningSpread(TM) Income ETF | Software Industry Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

 

Defiance CRCL LightningSpread(TM) Income ETF | Stablecoin Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stablecoin Risk. Circle’s performance depends significantly on the stability, trust, and circulation of Circle’s stablecoins, in particular the USDC and EURC stable coins (“Circle Stablecoins”), as well as the broader digital asset environment. Stablecoins remain in the early stages of adoption and regulatory development and are particularly susceptible to operational challenges, including those arising from surges in demand or systemic shocks. Stablecoins are subject to operational, market, and regulatory uncertainties. Changes in regulatory treatment, including legislation or enforcement actions restricting the issuance, redemption, or reserve management of stablecoins, could significantly impair Circle’s business model and financial condition. Circle’s stablecoins may be affected by market shocks, redemption activity, or disruptions in secondary marketplaces. Additionally, the broader digital asset industry is still developing standards around compliance, security, and governance. As a result, stablecoins face unique challenges that could impact their circulation, utility, and perception. Any adverse developments in these areas could materially affect the performance of Circle’s products and services.

 

Circle generates a large portion of its total revenue from interest income earned on the reserves backing its stablecoins. The size of these reserves is influenced by the amount of stablecoins in circulation, which in turn depends on demand for Circle’s products and services. The level of interest income is also affected by prevailing interest rates and the composition of the reserve assets. As a result, Circle’s revenue is subject to fluctuations in both market demand for stablecoins and macroeconomic conditions, including changes in interest rate environments.

 

The stablecoin market is becoming increasingly competitive, with rivals and potential entrants from traditional banks exploring stablecoin offerings. This could erode Circle’s market share and impact its revenue and profitability. Additionally, Circle is exposed to operational and cybersecurity risks inherent in managing a digital financial infrastructure, as well as technology risk tied to the performance of public blockchains on which Circle Stablecoins circulate.

 

While Circle Stablecoins are designed to be redeemable 1:1 for their underlying currencies (e.g., U.S. dollar, euro, etc.), there is a risk of a “de-peg,” where a token could trade below a 1:1 rate on third-party platforms. This could be triggered by events like a run on a bank holding Circle’s assets. Any perceived instability, lack of transparency or reserve shortfall could lead to rapid redemptions and reputational damage to Circle.

New Issuer Risk. Circle recently completed an initial public offering (i.e., CRCL has recently been made available on a stock exchange) and, as a result, its securities have a limited trading history. The share prices of new public companies may be highly volatile and may decline sharply following their initial public offering. Any of these factors may materially and adversely impact the share price of CRCL, increase the volatility of an investment in CRCL and have a negative impact on the performance of the Fund. Additionally, CRCL may in the future be traded by short sellers, which may put pressure on its supply and demand, further influencing volatility in its market price.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

 

Defiance COIN LightningSpread(TM) Income ETF | Derivatives Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance COIN LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance COIN LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance COIN LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance COIN LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

In particular, a large proportion of COIN may be traded by short sellers which may put pressure on the supply and demand for the common stock of Coinbase Global, Inc., further influencing volatility in its market price. Public perception and other factors outside of the control of Coinbase Global, Inc. may additionally impact COIN’s stock price due to Coinbase Global, Inc. garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against Coinbase Global, Inc. in the past. While Coinbase Global, Inc. continues to defend such actions, any judgment against Coinbase Global, Inc., or any future stockholder litigation could result in substantial costs and a diversion of the management of Coinbase Global, Inc.’s attention and resources. If COIN trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

Risk [Text Block]

Coinbase Global, Inc. Performance Risk. Coinbase Global, Inc. may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of COIN to decline. Coinbase Global, Inc. provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance Coinbase Global, Inc. provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If Coinbase Global, Inc.’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by Coinbase Global, Inc. could decline significantly.

Digital Assets Risk. Although the Fund does not directly invest in digital assets, it is exposed to their risks through options contracts referencing COIN. Digital asset technologies are highly disruptive and uncertain, and rapid technological advances may render existing assets obsolete. Additionally, intellectual property disputes among digital asset companies may undermine confidence in their viability. Digital asset marketplaces are often unregulated and may shut down due to fraud, security breaches, technical failures, or external attacks. These assets are typically stored in digital wallets, accessible only via private keys—if lost or stolen, the assets may be irretrievable. Digital assets also face manipulation risks and reliance on third-party products with potential vulnerabilities. Historically, digital assets have exhibited extreme price volatility and may become highly illiquid in stressed markets. Their value is not necessarily correlated to traditional economic or market forces, and demand for a digital asset could collapse, potentially driving its value to zero.

Risk [Text Block]

Financials Companies Risk. Financial companies, such as retail and commercial banks, brokerage firms, insurance companies and financial services companies, are especially subject to the adverse effects of economic recession, currency exchange rates, extensive government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets, industries or products (such as commercial and residential real estate loans) and competition from new entrants and blurred distinctions in their fields of business. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. The impact of changes in capital requirements, or recent or future regulation, on any financial company or on the financials sector as a whole cannot be predicted. The financials sector can be a target or cyberattacks, and may experience technology malfunctions and disruptions. These risks may be amplified for companies that operate online and digital platforms. In recent years, cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector.

Blockchain Related Company Risk. The performance of COIN, and consequently the Fund, is subject to risks associated with blockchain-related companies. Blockchain is a decentralized digital ledger that records cryptocurrency transactions, but its applications remain largely untested. Companies in this sector face volatile adoption rates, intense competition, and potential product obsolescence. Their financial performance is often tied to fluctuations in digital asset prices. Many blockchain companies operate with limited regulatory oversight, but stricter regulations could increase costs, restrict business activities, or even lead to prohibitions. Conversely, clearer regulations may benefit some companies. Additionally, blockchain firms store sensitive consumer data, making them targets for cybersecurity threats and theft. Loss or compromise of cryptographic keys could also result in irreversible asset losses.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance FcBk LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance FcBk LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance FcBk LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Prospectus [Line Items]  
Risk [Text Block]

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance FcBk LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned.

The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of META may be traded by short sellers which may put pressure on the supply and demand for the common stock of Meta Platforms, Inc., further influencing volatility in its market price. Public perception and other factors outside of the control of Meta Platforms, Inc. may additionally impact META’s stock price due to Meta Platforms, Inc. garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against Meta Platforms, Inc. in the past. While Meta Platforms, Inc. continues to defend such actions, any judgment against Meta Platforms, Inc., or any future stockholder litigation could result in substantial costs and a diversion of the management of Meta Platforms, Inc.’s attention and resources.

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance MSTR LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance MSTR LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Risk [Text Block]

Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

MSTR Trading Risk. The trading price of MSTR may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of MSTR may be traded by short sellers which may put pressure on the supply and demand for the common stock of MSTR, further influencing volatility in its market price. Public perception and other factors outside of the control of MSTR may additionally impact MSTR’s share price due to MSTR garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against MSTR in the past. While MSTR continues to defend such actions, any judgment against MSTR, or any future stockholder litigation could result in substantial costs and a diversion of the management of MSTR’s attention and resources. If MSTR trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

MSTR Performance Risk. MSTR may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of MSTR to decline. MSTR provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance MSTR provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If MSTR’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by MSTR could decline significantly.

Bitcoin Risk. While the Fund will not directly invest in digital assets, it will be subject to the risks associated with Bitcoin by virtue of its investments in options contracts that reference MSTR. Investing in Bitcoin exposes investors (such as MSTR and, in turn, MSTR shareholders) to significant risks that are not typically present in other investments. These risks include the uncertainty surrounding new technology, limited evaluation due to Bitcoin’s short trading history, and the potential decline in adoption and value over the long term. The extreme volatility of Bitcoin’s price is also a risk factor. Regulatory uncertainties, such as potential government interventions and conflicting regulations across jurisdictions, can impact the demand for Bitcoin and restrict its usage. Additionally, risks associated with the sale of newly mined Bitcoin, Bitcoin exchanges, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to Bitcoin-linked investments.

Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance NVDA LightningSpread(TM) Income ETF | Options Contracts [Member]

Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.

In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace.

Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

NVDA Trading Risk. The trading price of NVDA may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of NVDA may be traded by short sellers which may put pressure on the supply and demand for the common stock of NVIDIA Corporation, further influencing volatility in its market price. Public perception and other factors outside of the control of NVIDIA Corporation may additionally impact NVDA’s stock price due to NVIDIA Corporation garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against NVIDIA Corporation in the past. While NVIDIA Corporation continues to defend such actions, any judgment against NVIDIA Corporation, or any future stockholder litigation could result in substantial costs and a diversion of the management of NVIDIA Corporation’s attention and resources. If NVDA trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

NVIDIA Corporation Performance Risk. NVIDIA Corporation may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of NVDA to decline. NVIDIA Corporation provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance NVIDIA Corporation provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If NVIDIA Corporation’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by NVIDIA Corporation could decline significantly.

 

NVIDIA Corporation’s accelerated computing platforms address four large markets: Gaming, Data Center, Professional Visualization, and Automotive. These markets experience rapid changes in technology, customer requirements, new product introductions and enhancements, and industry standards.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance ORCL LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance ORCL LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance ORCL LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

ORCL Trading Risk. The trading price of ORCL may be subject to volatility and could experience wide fluctuations due to various factors. Short sellers may also play a significant role in trading ORCL, potentially affecting the supply and demand dynamics and contributing to market price volatility. Public perception and external factors beyond the company’s control may influence ORCL’s stock price disproportionately. Additionally, following periods of market volatility, companies have faced securities class action litigation. Any adverse judgment or future stockholder litigation could result in substantial costs and divert management’s attention and resources.

ORCL provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance ORCL provides may not ultimately be accurate. If ORCL’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by ORCL could decline significantly.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

 

Defiance PLTR LightningSpread(TM) Income ETF | Derivatives Risks [Member]

Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance PLTR LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance PLTR LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance PLTR LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

PLTR Trading Risk. The trading price of PLTR may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of PLTR may be traded by short sellers which may put pressure on the supply and demand for the common stock of PLTR, further influencing volatility in its market price. Public perception and other factors outside of the control of PLTR may additionally impact PLTR’s stock price due to PLTR garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against PLTR in the past. While PLTR continues to defend such actions, any judgment against PLTR, or any future stockholder litigation could result in substantial costs and a diversion of the management of PLTR’s attention and resources. If PLTR trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

Palantir Technologies Inc. Performance Risk. Palantir Technologies Inc. may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of PLTR to decline. Palantir Technologies Inc. provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance Palantir Technologies Inc. provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If Palantir Technologies Inc.’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by Palantir Technologies Inc. could decline significantly.

Palantir Technologies Inc. may struggle to hire, retain, and train qualified personnel, which is crucial for meeting customer demand. The use of AI could lead to reputational harm or liability issues, and there may be difficulties in obtaining, maintaining, protecting, and enforcing intellectual property rights. Additionally, the platform could encounter real or perceived errors, failures, defects, or bugs, and reliance on third-party technology could pose risks if it becomes difficult to replace or causes errors. Finally, Palantir Technologies Inc.’s AI platform will be subject to complex and evolving U.S. and non-U.S. laws and regulations regarding privacy, data protection, security, and technology protection.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

 

Defiance TSLA LightningSpread(TM) Income ETF | Derivatives Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance TSLA LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying Security, option prices may not perfectly replicate the rate of change of the Underlying Security prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying Security declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance TSLA LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

 

Defiance TSLA LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance TSLA LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Electric Vehicles Risk. The future growth and success of Tesla, Inc. are dependent upon consumers’ demand for electric vehicles, and specifically, its vehicles in an automotive industry that is generally competitive, cyclical and volatile. If the market for electric vehicles in general and Tesla, Inc. vehicles in particular does not develop as Tesla, Inc. expects, develops more slowly than it expects, or if demand for its vehicles decreases in its markets or its vehicles compete with each other, the business, prospects, financial condition and operating results of Tesla, Inc. may be harmed. Tesla, Inc. is still at an earlier stage of development and have limited resources and production relative to established competitors that offer internal combustion engine vehicles. In addition, electric vehicles still comprise a small percentage of overall vehicle sales. As a result, the market for Tesla, Inc. vehicles could be negatively affected by numerous factors, such as: (i) perceptions about electric vehicle features, quality, safety, performance and cost; (ii) perceptions about the limited range over which electric vehicles may be driven on a single battery charge, and access to charging facilities; (iii) competition, including from other types of alternative fuel vehicles, plug-in hybrid electric vehicles and high fuel-economy internal combustion engine vehicles; (iv) volatility in the cost of oil and gasoline, such as wide fluctuations in crude oil prices; (v) government regulations and economic incentives; and (vi) concerns about the future viability of Tesla, Inc. Finally, the target demographics for Tesla, Inc. vehicles are highly competitive. Sales of vehicles in the automotive industry tend to be cyclical in many markets, which may expose Tesla, Inc. to further volatility.

Automotive Companies Risk. The automotive industry can be highly cyclical, and companies in the industry may suffer periodic operating losses. Automotive companies can be significantly affected by labor relations, fluctuating component prices and supplier disruptions. Developments in automotive technologies (e.g., autonomous vehicle technologies) may require significant capital expenditures that may not generate profits for several years, if ever. Automotive companies may be significantly subject to government policies and regulations regarding imports and exports of automotive products. Governmental policies affecting the automotive industry, such as taxes, tariffs, duties, subsidies, and import and export restrictions on automotive products can influence industry profitability. In addition, such companies must comply with environmental laws and regulations, for which there may be severe consequences for non-compliance. While most of the major automotive manufacturers are large companies, certain others may be non-diversified in both product line and customer base and may be more vulnerable to certain events that may negatively impact the automotive industry.

Elon Musk’s Influence on TSLA Risk. The Fund’s performance is closely tied to the stock price of TSLA, which may be significantly impacted by the actions, decisions, and public statements of its CEO, Elon Musk. His social media activity, interviews, and public remarks have historically caused sharp volatility in TSLA’s stock price and have, at times, resulted in regulatory scrutiny and legal proceedings. Additionally, Mr. Musk’s leadership decisions, including strategic shifts or changes in Tesla’s business model, could introduce uncertainty. His involvement in multiple high-profile ventures, such as SpaceX and X (formerly Twitter), may also raise concerns about his focus on Tesla. Furthermore, any potential reduction in his role or departure from Tesla could negatively affect investor sentiment. Given Mr. Musk’s influence, TSLA’s valuation may be subject to sudden and unpredictable changes, which could materially impact the Fund’s performance.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance Bitcoin LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETP, option prices may not perfectly replicate the rate of change of the Underlying ETP prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETP declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Bitcoin LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETP, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETP experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance Bitcoin LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance Bitcoin LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

  Digital Assets Risk: Digital assets like bitcoin, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility.

IBIT Risks. The Fund invests in instruments based on the value of IBIT. This subjects the Fund to certain of the same risks as if it owned shares of IBIT as well as the risks associated with the assets held by IBIT, even though the Fund does not hold those assets directly. The value of IBIT will fluctuate with the market price of bitcoin, which may be affected by economic conditions, regulatory developments, supply and demand for bitcoin, technological developments, investor sentiment and other factors. Brokerage, custody, management fees and other expenses may negatively impact the performance of IBIT and therefore the value of the Fund’s shares.

Risk [Text Block]
  Digital Asset and Market Risks. IBIT invests in bitcoin, a digital asset that is relatively new, highly volatile, and subject to evolving market dynamics. The market value of bitcoin is influenced by supply and demand on digital asset trading platforms, adoption of the Bitcoin network, technological advancements, macroeconomic conditions, and regulatory developments. These factors are unpredictable and may result in significant and rapid declines in value. Digital asset markets are less mature than traditional securities markets and may be more vulnerable to manipulation, fraud, hacking, loss of access, or other operational failures. The price of bitcoin has historically exhibited extreme volatility, and the price of IBIT shares may experience similar fluctuations. Such volatility may be driven by speculative trading activity, shifts in investor sentiment, or changes in the regulatory or technological environment. As a result, the IBIT shares may trade at prices that vary materially from the value of its bitcoin holdings, particularly if market liquidity is constrained or trading spreads widen.

  Custody and Operational Risks. The IBIT Trust’s bitcoin is held in custody with a third-party custodian under established security and operational protocols. Despite these safeguards, the IBIT Trust remains exposed to risks such as cybersecurity breaches, operational errors, insolvency of service providers, or the misappropriation or loss of bitcoin. Bitcoin transactions are irrevocable, and incorrectly executed or unauthorized transfers cannot be reversed. A security incident involving the IBIT Trust’s custodian or other service providers could result in a partial or total loss of assets, interruption of operations, or damage to the IBIT Trust’s reputation, each of which could materially reduce the value of the shares of IBIT. The IBIT Trust relies on key service providers, including its custodian, prime execution agent, and bitcoin trading counterparties. The termination or failure of any of these entities to perform their obligations could impair the IBIT Trust’s ability to safeguard assets, process creations and redemptions, or maintain normal operations. In addition, the loss of critical banking relationships or the failure of a financial institution used by IBIT’s prime execution agent could disrupt the IBIT Trust’s ability to facilitate transactions or lead to financial losses.

Adverse legislative or regulatory actions, including restrictions or prohibitions on bitcoin use, trading, mining, or custody, could materially reduce the value or liquidity of bitcoin and adversely affect the IBIT Trust’s operations. If regulators were to classify the Trust, its Sponsor, or other key service providers such as bitcoin trading counterparties as money services businesses or money transmitters, those entities could incur significant compliance costs and operational burdens. Changes in regulatory interpretation could further require new registrations or adherence to additional requirements, resulting in extraordinary and potentially nonrecurring expenses. The legal and tax treatment of digital assets for U.S. federal, state, and local income tax purposes remains unsettled.

Defiance Bitcoin LightningSpread(TM) Income ETF | Bitcoin Investment Risks [Member]

Risk [Text Block]

Bitcoin Investment Risks. The Fund’s indirect investment in bitcoin exposes it to the unique risks of this emerging innovation. Bitcoin’s price is highly volatile, and its market is influenced by the changing bitcoin network, fluctuating acceptance levels, and unpredictable usage trends. Not being a legal tender and operating outside central authority systems like banks, bitcoin faces potential government restrictions. For instance, some countries may limit or ban bitcoin transactions, negatively impacting its market value.

 

The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as “whales,” can significantly influence bitcoin’s price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin’s price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.

 

Updates to bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact bitcoin’s demand and the Fund’s performance. The extreme volatility of bitcoin’s market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin’s price and the Fund’s investments.

 

The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.

 

Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.

 

Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.

 

The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

 

Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.

 

The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.

 

Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.

 

Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin’s price, which may deter widespread adoption by businesses and consumers.

 

The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.

 

Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETP, option prices may not perfectly replicate the rate of change of the Underlying ETP prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETP declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Ethereum LightningSpread(TM) Income ETF | Swap Agreements [Member]

Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETP, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETP experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance Ethereum LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance Ethereum LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

  No 1940 Act Protections. The Underlying ETP is not registered as an investment company subject to the 1940 Act. Accordingly, investors in the Underlying ETP would not have the protections expressly provided by that statute, including: provisions preventing Underlying ETP insiders from managing the Underlying ETP to their benefit and to the detriment of shareholders; provisions preventing an Underlying ETP from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying ETP earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in the Underlying ETP’s character without the consent of shareholders.

ETHE Risks. The Fund invests in instruments based on the value of ETHE. This subjects the Fund to certain of the same risks as if it owned shares of ETHE as well as the risks associated with the assets held by ETHE, even though the Fund does not hold those assets directly. The value of ETHE will fluctuate with the market price of Ether, which may be affected by economic conditions, regulatory developments, supply and demand for bitcoin, technological developments, investor sentiment and other factors.

  ETHE and Digital Asset Exposure Risks. The Fund invests in options contracts based on the value of ETHE. Accordingly, the Fund is subject to certain of the same risks as if it owned shares of ETHE, as well as risks associated with the instruments in which ETHE invests, even though the Fund does not hold those instruments directly. The value of ETHE fluctuates based on the price of Ether, which is influenced by regulatory developments, technological innovation, network adoption, competition, investor sentiment, and overall market conditions. Brokerage, custody, and management fees, as well as other expenses, may reduce the performance of ETHE and, consequently, the value of the Fund’s shares. Ether is a digital asset that is relatively new and subject to substantial volatility. The market value of Ether is determined primarily by supply and demand on digital asset trading platforms, adoption of blockchain technology, and global economic and regulatory conditions. Digital asset markets are largely unregulated and may be more vulnerable to fraud, manipulation, or trading halts than traditional securities markets. ETHE currently accepts only cash creations and redemptions rather than in-kind transactions involving Ether. This structural limitation may impair the efficiency of the arbitrage mechanism that normally aligns the market price of shares with their net asset value, potentially resulting in shares trading at significant premiums or discounts. The inability to facilitate in-kind creations or redemptions may also increase operational risk and transaction costs and could limit liquidity during periods of market stress.

  Ethereum Network and Technology Risks. ETHE’s performance depends on the proper functioning of the Ethereum network, an open-source, decentralized blockchain. Any disruption, failure, or modification to the network, including forks, consensus changes, or vulnerabilities, may adversely affect the value of Ether and, in turn, ETHE. Periods of network congestion or elevated transaction fees may also reduce efficiency and market confidence. ETHE relies on a third-party custodian to maintain its Ether holdings in secure storage. While such arrangements are designed to minimize the risk of loss, ETHE remains subject to operational, cybersecurity, or insolvency risks associated with its custodian, which could result in partial or total loss of assets. ETHE’s shareholders will not receive any benefits arising from hard forks, airdrops, or similar events affecting the Ethereum network. ETHE will irrevocably abandon any rights to new digital assets distributed through such events, which could prevent shareholders from realizing potential economic gains associated with those occurrences.

  Regulatory and Legal Risks. Digital assets and related investment vehicles operate within evolving and uncertain regulatory frameworks. Changes in laws, regulations, or governmental interpretations—domestically or abroad—could materially affect ETHE’s operations or the value of Ether. A determination that Ether constitutes a security or other regulated instrument could restrict trading, reduce liquidity, and adversely impact ETHE’s ability to achieve its investment objective. The regulatory landscape for digital assets varies significantly across jurisdictions. Adverse actions by regulators in key markets, including the United States, the European Union, and Asia—such as restrictions on trading platforms, reclassification of Ether, or limitations on custody—could materially affect the Ether market and ETHE’s valuation. Divergent global regulations may further increase compliance complexity and systemic risk. Uncertainty regarding whether registered broker-dealers may hold or transact in Ether under existing financial responsibility rules has delayed the development of in-kind creation and redemption mechanisms. Regulatory determinations in this area, or lack thereof, could materially impact ETHE’s structure, operations, and efficiency.

  Market, Volatility, and Liquidity Risks. The price of Ether has been, and may continue to be, highly volatile. Ether’s value may fluctuate sharply due to speculative trading, macroeconomic events, or changes in investor sentiment. Ether may experience rapid and significant declines in value, including to zero, resulting in substantial losses to ETHE and the Fund. Because ETHE shares are not redeemable for Ether and creations are limited, shares may trade at a substantial premium or discount to their net asset value (“NAV”). Market demand, liquidity, and investor perceptions can contribute to persistent deviations between trading price and NAV. The absence of in-kind creations and redemptions may exacerbate such deviations and result in less effective arbitrage during periods of volatility or market stress.

Failures or disruptions in these systems could adversely affect ETHE’s ability to value its holdings, maintain custody of its assets, or conduct routine operations. Insolvency or default by any key service provider could result in loss or delay in accessing ETHE’s Ether holdings. Both ETHE and the Ethereum network are subject to cybersecurity threats, including hacking, theft, and data breaches. A successful attack could result in loss of assets, operational disruption, or damage to investor confidence in digital asset markets generally.
Defiance Ethereum LightningSpread(TM) Income ETF | Digital Asset Market Structure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Digital Asset Market Structure Risks. The Fund is indirectly exposed to the trading venues on which Ether is bought and sold. Digital asset trading platforms are relatively new and, in many cases, less regulated than traditional securities or commodities exchanges. Failures, insolvencies, cyber incidents, or fraudulent activity at such trading platforms could cause severe market disruptions and impair ETHE’s ability to value or liquidate its holdings. A substantial portion of Ether trading occurs on trading platforms located outside the United States. Offshore markets may lack transparency, offer limited investor protections, and be prone to market manipulation. Failures or restrictions in such markets could reduce Ether liquidity and pricing efficiency. Because of these market structure limitations and ETHE’s reliance on cash creations and redemptions, the arbitrage mechanism may not function as efficiently as it does for comparable products that transact in-kind, increasing the likelihood of share price deviations from NAV.

  Environmental, Technological, and Smart-Contract Risks. Although Ethereum transitioned from a proof-of-work to a proof-of-stake consensus mechanism, environmental and energy-use considerations continue to influence regulatory and investor perceptions. Future policy changes or market preferences motivated by environmental concerns could adversely affect Ether’s adoption or valuation. The Ethereum network also supports decentralized applications and “smart contracts,” including decentralized finance (“DeFi”) protocols. Security vulnerabilities, operational failures, or fraud involving these applications could undermine confidence in the Ethereum ecosystem and negatively affect the price of Ether. ETHE is currently prohibited from engaging in staking or participating in the Ethereum proof-of-stake validation mechanism. As a result, it will not receive any staking rewards or other income that could otherwise accrue to direct holders of Ether. This limitation may place ETHE at a competitive disadvantage relative to vehicles or investors able to engage in staking activities.

A decline in the value of Ether would have a direct and significant negative impact on ETHE’s net asset value and, consequently, on the value of the Fund’s investments. ETHE’s reliance on a limited number of custodians, liquidity providers, and other key service providers may further increase concentration risk in its operational and counterparty relationships.

 

Defiance Ethereum LightningSpread(TM) Income ETF | Ether Risks [Member]

Risk [Text Block]

Ether Risks. The Fund’s exposure to ETHE indirectly exposes the Fund to the risks associated with an investment in ether. Ether is a relatively new innovation and is subject to unique and substantial risks. The market for ether is subject to rapid price swings, changes and uncertainty. The further development of the Ethereum Network and the acceptance and use of ether are subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the Ethereum Network or the acceptance of ether may adversely affect the price and liquidity of ether. Ether is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact ether trading venues. Additionally, if one or a coordinated group of validators were to gain control of 33% or more of staked ether (i.e., ether that is deposited to support the Ethereum Network), they would have the ability to execute extensive attacks, manipulate transactions and fraudulently obtain ether. If such a validator or group of validators were to gain control of one-third of staked ether, they could halt payments. A significant portion of ether is held by a small number of holders sometimes referred to as “whales”. Transactions by these holders may influence the price of ether.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, ether and ether trading venues are largely unregulated. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote ether in a way that artificially increases the price of ether). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of ether trading venues have been closed due to fraud, failure or security breaches. Investors in ether may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses.

 

The realization of any of these risks could result in a decline in the acceptance of ether and consequently a reduction in the value of ether, ether futures, and the Fund.

 

Additionally, legal or regulatory changes may negatively impact the operation of the Ethereum Network or restrict the use of ether. For example, if ether were determined to be or were expected to be determined to be a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in ether, trading in ether futures may become significantly more volatile and/or completely halted, and the value of an investment in the Fund could decline significantly and without warning, including to zero.

 

Finally, the creation of a “fork” (as described above) or a substantial giveaway of ether (sometimes referred to as an “air drop”) may result in significant and unexpected declines in the value of ether, ether futures, and the Fund. A fork may be intentional, such as the ‘Merge.’ The ‘Merge’ refers to protocol changes altering the method by which transactions are validated.

 

The market for ether futures may be less developed, and potentially less liquid and more volatile, than more established futures markets. While the ether futures market has grown substantially since ether futures commenced trading, there can be no assurance that this growth will continue. The price for ether futures contracts is based on a number of factors, including the supply of and the demand for ether futures contracts. Market conditions and expectations, regulatory limitations or limitations imposed by the listing exchanges or futures commission merchants (“FCMs”) (e.g., margin requirements, position limits, and accountability levels), collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for ether futures contracts.

 

Market conditions and expectations, margin requirements, position limits, accountability levels, collateral requirements, availability of counterparties, and other factors may also limit the Fund’s ability to achieve its desired exposure to ether futures contracts. If the Fund is unable to achieve such exposure it may not be able to meet its investment objective and the Fund’s returns may be different or lower than expected. Additionally, collateral requirements may require the Fund to liquidate its positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like ether futures may be considered aggressive and may expose the Fund to significant risks. These risks include counterparty risk and liquidity risk.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance Gold LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETP, option prices may not perfectly replicate the rate of change of the Underlying ETP prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETP declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Gold LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETP, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETP experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance Gold LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance Gold LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

GLD Risks. The Fund invests in derivative instruments that are based on the value of GLD. This subjects the Fund to certain of the same risks as if it owned shares of GLD, even though it does not. By virtue of the Fund’s investments in derivative instruments that are based on the value of GLD, the Fund may also be subject to the following risks:

 

Defiance Gold LightningSpread(TM) Income ETF | GLD Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
GLD Trading Risk. An investment in GLD is subject to substantial risks, in particular risks associated with investing in the gold market. GLD is subject to market fluctuations influenced by large-scale gold sales, especially during economic crises, which can adversely impact gold prices and, in turn, the investment value of the Shares. Historical instances, such as the 2008 financial crisis, demonstrated this volatility, where substantial gold sales led to a marked decrease in its market price. Moreover, large disposals of gold by the official sector – encompassing central banks and other government entities – could result in a supply surplus, potentially diminishing gold’s market value. The valuation of the gold held by GLD is closely tied to the LBMA Gold Price PM. This benchmark is established through a bidding process by various market participants and any inaccuracies in its calculation or modifications to the benchmark process could significantly impact the Trust’s gold valuation and the investment value in Shares.

 

GLD faces significant custodial and safeguarding risks regarding its gold holdings. There is an inherent danger of these gold bars being lost, damaged, stolen, or becoming inaccessible due to factors such as natural disasters or terrorism. GLD does not insure its gold, and the insurance held by its custodian might not fully cover potential losses. The custodian’s liability is restricted to direct losses from negligence, fraud, or willful default, limited to the gold’s market value at the time of the incident, a constraint that also applies to any subcustodians. Additionally, legal and practical difficulties in foreign jurisdictions could complicate the enforcement of rights or claims. The custodian, not specifically regulated for gold bullion custody, relies on industry best practices and internal controls, which presents a security risk for GLD’s gold. Furthermore, gold in GLD’s unallocated accounts isn’t segregated from the custodian’s assets, thus in the event of the custodian’s insolvency, GLD would be an unsecured creditor, potentially leading to delays and extra costs in recovering allocated gold. These challenges in dealing with subcustodians and the potential complications in legal actions due to the lack of direct contractual arrangements and the intricacies of foreign legal systems highlight the significant custodial risks in investing in GLD Shares.

Indirect Investments in GLD. GLD is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser, or their respective affiliates and is not involved with the offering of the Fund in any way and has no obligation to consider your Shares in taking any corporate action that might affect the value of Shares. GLD is not a registered investment company subject to the 1940 Act. Accordingly, investors in GLD (including the Fund via its indirect investments) do not have the protections expressly provided by that statute, including: provisions preventing GLD insiders from managing GLD to their benefit and to the detriment of shareholders; provisions preventing GLD from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing GLD earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in GLD’s character without the consent of shareholders. Investors in the Fund will not have voting rights and will not be able to influence management of GLD but will be exposed to the performance of GLD. Investors in the Fund will not have rights to receive dividends or other distributions or any other rights with respect to the Underlying ETP but will be subject to declines in the performance of the Underlying ETP.

Gold Performance Risk. Price movements in gold may fluctuate quickly and dramatically, have a historically low correlation with the returns of the stock and bond markets, and may not correlate to the price movements in other asset classes. The price of gold bullion can be significantly affected by international monetary and political developments such as currency devaluation or revaluation, central bank movements, economic and social conditions within a country, transactional or trade imbalances, or trade or currency restrictions between countries. Physical gold bullion has sales commission, storage, insurance and auditing expenses. Additional factors that impact the price of gold include, but are not limited to, overall market movements, changes in interest rates, changes in the global supply and demand for gold, the quantity of gold imports and exports, factors that impact gold production, such as drought, floods and weather conditions, technological advances in the processing and mining of gold and an increase in the hedging of precious metals, such as gold. Investments in gold generally may be speculative and subject to greater price volatility than investments in other types of assets. The price of metals, such as gold, is related to, among other things, worldwide metal prices and extraction and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, and as a result, the Fund’s share price may be more volatile than other types of investments.

Risk [Text Block]

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Concentration Risk. The Fund’s investment exposure will be concentrated in (or substantially exposed to) the same industry or groups of industries, if any, to which the Underlying ETF is concentrated. As a result, the Fund may be more susceptible to loss due to adverse occurrences that affect the price of such industries more than the market as a whole.

Risk [Text Block]

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

 

Defiance Gold Miners LightningSpread(TM) Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

Risk [Text Block]

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

GDX Risks. The Fund invests in derivative instruments that are based on the value of an ETF, specifically GDX. This subjects the Fund to certain of the same risks as if it owned shares of GDX, as well as the types of instruments in which GDX invests, even though it does not. The value of GDX will fluctuate over time based on fluctuations in the values of the securities held by GDX, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. Brokerage, tax and other expenses may negatively impact the performance of GDX and, in turn, the value of the Fund’s shares. Since GDX is an ETF, it is also subject to the same structural risks as the Fund, which is an ETF. By virtue of the Fund’s investments in derivative instruments that are based on the value of GDX, the Fund may also be subject to the following risks:

  Risk of Investing in Gold and Silver Mining Companies. The Fund is exposed indirectly to gold and silver mining companies selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. GDX will be sensitive to, and its performance will depend to a greater extent on, the overall condition of gold and silver mining companies. Investments related to gold and silver are considered speculative and are affected by a variety of factors. Competitive pressures may have a significant effect on the financial condition of gold and silver mining companies. Also, gold and silver mining companies are highly dependent on the price of gold and silver bullion, respectively, and may be adversely affected by a variety of worldwide economic, financial and political factors. The price of gold and silver may fluctuate substantially over short periods of time so GDX’s, and therefore the Fund’s, Share price may be more volatile than other types of investments. Fluctuation in the prices of gold and silver may be due to a number of factors, including changes in inflation, changes in currency exchange rates and changes in industrial and commercial demand for metals (including fabricator demand). Additionally, increased environmental or labor costs may depress the value of metal investments.

  Special Risk Considerations of Investing in Canadian Issuers. The Fund is exposed indirectly to Canadian issuers selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. Investments in securities of Canadian issuers, including issuers located outside of Canada that generate significant revenue from Canada, involve risks and special considerations not typically associated with investments in the U.S. securities markets. The Canadian economy is very dependent on the demand for, and supply and price of, natural resources. The Canadian market is relatively concentrated in issuers involved in the production and distribution of natural resources. There is a risk that any changes in natural resources sectors could have an adverse impact on the Canadian economy. Additionally, the Canadian economy is heavily dependent on relationships with certain key trading partners including the United States, countries in the European Union and China. Because the United States is Canada’s largest trading partner and foreign investor, the Canadian economy is dependent on and may be significantly affected by the U.S. economy. Reduction in spending on Canadian products and services or changes in the U.S. economy may adversely impact the Canadian economy. Trade agreements may further increase Canada’s dependency on the U.S. economy, and uncertainty as to future trade agreements may cause a decline in the value of GDX’s, and therefore the Fund’s, Shares. Past periodic demands by the Province of Quebec for sovereignty have significantly affected equity valuations and foreign currency movements in the Canadian market and such demands may have this effect in the future. In addition, certain sectors of Canada’s economy may be subject to foreign ownership limitations. This may negatively impact GDX’s, and therefore the Fund’s, ability to invest in Canadian issuers and to track the Gold Miners Index.

Investments in securities of Australian issuers involve risks and special considerations not typically associated with investments in the U.S. securities markets. The Australian economy is heavily dependent on exports from the agriculture and mining industries. This makes the Australian economy susceptible to fluctuations in the commodity markets. Australia is also dependent on trading with key trading partners.

Risk [Text Block]
  Special Risk Considerations of Investing in African Issuers. Investing in securities of African issuers, including companies outside Africa that derive significant revenue from the continent, involves risks not typically associated with U.S. markets. These risks include political instability, government intervention, confiscatory taxation, armed conflict, terrorism, infectious disease outbreaks, and social unrest. Additionally, Africa is prone to natural disasters and economic volatility tied to environmental events. Its securities markets are underdeveloped and often less correlated with global economic cycles. Some African nations are classified as “frontier markets,” which have smaller economies and less developed capital markets, making them particularly susceptible to market volatility, illiquidity, inflation, and trading restrictions. Moreover, certain African economies are heavily dependent on commodity exports such as oil, gold, and agricultural products, making them vulnerable to price fluctuations. Foreign investment restrictions, government controls, and additional taxation further heighten investment risks.

 

  These factors make investing in African issuers significantly riskier than investing in developed markets, potentially impacting the value of GDX’s shares. Capital repatriation restrictions and currency fluctuations, especially in countries with currencies pegged to the U.S. dollar, can further complicate investment returns. Delays or limitations on converting and repatriating funds may reduce liquidity and hinder GDX’s ability to meet its investment objectives. In times of market stress, GDX may need to suspend redemptions or limit new creations of shares, leading to significant premiums or discounts in trading prices. Prolonged redemption pressures could increase transaction costs and result in higher taxable distributions. Additionally, the presence of illiquid assets in GDX’s portfolio may make valuation more challenging.

  Risk of Investing in Foreign Securities. The Fund is exposed indirectly to the securities of foreign issuers selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. Investments in the securities of foreign issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Because certain foreign securities markets may be limited in size, the activity of large traders may have an undue influence on the prices of securities that trade in such markets. GDX, and therefore the Fund, invests in securities of issuers located in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments.

  Risk of Investing in Emerging Market Issuers. The Fund is exposed indirectly to the securities of emerging market issuers selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. Investments in securities of emerging market issuers are exposed to a number of risks that may make these investments volatile in price or difficult to trade. Emerging markets are more likely than developed markets to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories. Political risks may include unstable governments, nationalization, restrictions on foreign ownership, laws that prevent investors from getting their money out of a country and legal systems that do not protect property rights as well as the laws of the United States. Market risks may also include economies that concentrate in only a few industries, securities issues that are held by only a few investors, liquidity issues and limited trading capacity in local exchanges and the possibility that markets or issues may be manipulated by foreign nationals who have inside information. The frequency, availability and quality of financial information about investments in emerging markets varies. GDX, and therefore the Fund, has limited rights and few practical remedies in emerging markets and the ability of U.S. authorities to bring enforcement actions in emerging markets may be limited, and GDX’s, and therefore the Fund’s, passive investment approach does not take account of these risks. All of these factors can make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.

  Risk of Investing in Depositary Receipts. The Fund may be exposed indirectly to depositary receipts selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such depositary receipts. GDX, and therefore the Fund, may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Depositary receipts are receipts listed on U.S. or foreign exchanges issued by banks or trust companies that entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market and, if not included in the Gold Miners Index, may negatively affect GDX’s, and therefore the Fund’s, ability to replicate the performance of the Gold Miners Index. The issuers of depositary receipts may discontinue issuing new depositary receipts and withdraw existing depositary receipts at any time, which may result in costs and delays in the distribution of the underlying assets to GDX, and therefore the Fund, and may negatively impact GDX’s, and therefore the Fund’s, performance and GDX’s, and therefore the Fund’s, ability to replicate/track the performance of its Index.

The Fund is exposed indirectly to small- and medium-capitalization companies selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. Small- and medium-capitalization companies may be more volatile and more likely than large-capitalization companies to have narrower product lines, fewer financial resources, less management depth and experience and less competitive strength. In addition, these companies often have greater price volatility, lower trading volume and less liquidity than larger more established companies. Returns on investments in securities of small- and medium-capitalization companies could trail the returns on investments in securities of large-capitalization companies.

  Equity Securities Risk. The Fund is exposed indirectly to the equity securities of companies selected by GDX’s investment adviser, which subjects the Fund to the risks associated with such companies. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the markets in which the issuers of securities held by the Fund participate, or factors relating to specific issuers in which the Fund invests. Equity securities are subordinated to preferred securities and debt in a company’s capital structure with respect to priority in right to a share of corporate income, and therefore will be subject to greater dividend risk than preferred securities or debt instruments. In addition, while broad market measures of equity securities have historically generated higher average returns than fixed income securities, equity securities have generally also experienced significantly more volatility in those returns, although under certain market conditions fixed income securities may have comparable or greater price volatility.

  Foreign Currency Risk. The Fund is subject to foreign currency risk indirectly due to GDX’s investments. Because all or a portion of the income received by GDX from its investments and/or the revenues received by the underlying issuer will generally be denominated in foreign currencies, GDX’s exposure to foreign currencies and changes in the value of foreign currencies versus the U.S. dollar may result in reduced returns for GDX (and therefore the Fund), and the value of certain foreign currencies may be subject to a high degree of fluctuation. Moreover, GDX may incur costs in connection with conversions between U.S. dollars and foreign currencies.

  Index Tracking Risk. GDX’s returns may not match those of the Index due to operating expenses, transaction costs, and regulatory or market disruptions. Errors in Index data, computation, or methodology may further impact performance. Tracking error may increase due to rebalancing costs, ad hoc Index changes, legal restrictions, liquidity issues, adverse tax consequences, and regulatory limitations. The use of depositary receipts, fair value pricing, currency convertibility issues, and withholding taxes may also contribute to tracking deviations. Market volatility, reliance on borrowings for redemptions, and tax-related securities sales could further increase tracking risk. As a result, GDX’s returns may deviate significantly from those of the Index, particularly during periods of rebalancing or reconstitution.

  Passive Management Risk. GDX is not actively managed, meaning it generally does not sell securities unless they are removed from the Index, even if an issuer is in financial distress. If a security is removed, GDX may be forced to sell it at an unfavorable time or price. GDX is exposed to market fluctuations caused by economic and political events, interest rate changes, and broader market trends. The Index may not always reflect an optimal mix of securities for all economic conditions, and delays in scheduled rebalancing could further impact performance. Unlike actively managed funds, GDX does not employ defensive strategies to mitigate market volatility, potentially leading to underperformance during adverse market conditions.

A significant gain or loss in a single investment may have an outsized impact on GDX’s net asset value. Additionally, GDX’s portfolio may be concentrated in specific sectors or industries based on the Index’s composition.

Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance Silver LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETP, option prices may not perfectly replicate the rate of change of the Underlying ETP prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETP declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Silver LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETP, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETP experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

SLV Risks. The Fund invests in derivative instruments that are based on the value of SLV. This subjects the Fund to certain of the same risks as if it owned shares of SLV, even though it does not. By virtue of the Fund’s investments in derivative instruments that are based on the value of SLV, the Fund may also be subject to the following risks:

 

Defiance Silver LightningSpread(TM) Income ETF | SLV Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SLV Trading Risk. An investment in SLV is subject to various risks, notably those linked to the dynamics and perception of the LBMA Silver Price. The LBMA, or London Bullion Market Association, plays a crucial role in setting the benchmark for silver prices. It is an international trade association representing the London market for gold and silver bullion, which has a major influence on the global bullion markets. The LBMA Silver Price, determined through an electronic auction managed by ICE Benchmark Administration, is central to the Trust’s valuation and operation. However, potential electronic failures or concerns about the LBMA Silver Price being susceptible to manipulation could lead to delays or inaccuracies in the auction price. This uncertainty could affect the Trust’s valuation of its silver holdings, the calculation of fees, and the pricing of silver sales. Moreover, a loss of confidence in the fairness or integrity of the LBMA Silver Price could change investor behavior, thereby impacting the overall silver market and the value of the shares.

 

SLV’s exclusive investment in silver heightens its volatility compared to more diversified portfolios. Silver prices, which SLV’s net asset value closely tracks, have historically experienced significant and unpredictable fluctuations. SLV is a speculative investment, suitable primarily for those who can absorb potential losses. The physical silver market’s supply and demand dynamics can further complicate this investment. For example, if the demand for silver exceeds the available supply that meets SLV’s standards, it could obstruct the issuance of new shares. Such a supply-demand mismatch may lead to increased volatility in the share price and a significant divergence from the net asset value. This scenario highlights the speculative nature of silver investments and emphasizes the need for investors to be cognizant of the potential for substantial losses or gains, influenced by market conditions and the inherent volatility of silver.

Indirect Investments in SLV. SLV is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser, or their respective affiliates and is not involved with the offering of the Fund in any way and has no obligation to consider your Shares in taking any corporate action that might affect the value of Shares. SLV is not a registered investment company subject to the 1940 Act. Accordingly, investors in SLV (including the Fund via its indirect investments) do not have the protections expressly provided by that statute, including: provisions preventing SLV insiders from managing SLV to their benefit and to the detriment of shareholders; provisions preventing SLV from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing SLV earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in SLV’s character without the consent of shareholders. Investors in the Fund will not have voting rights and will not be able to influence management of SLV but will be exposed to the performance of SLV. Investors in the Fund will not have rights to receive dividends or other distributions or any other rights with respect to the Underlying ETP but will be subject to declines in the performance of the Underlying ETP. Although the Fund invests in SLV only indirectly, the Fund’s investments are subject to loss as a result of these risks.

 

Defiance Silver LightningSpread(TM) Income ETF | SLV Performance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SLV Performance Risk. The iShares Silver Trust may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of SLV to decline. The iShares Silver Trust provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the iShares Silver Trust provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If iShares Silver Trust’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by iShares Silver Trust could decline significantly.

 

Following an investment in the iShares Silver Trust, several factors may have the effect of causing a decline in the prices of silver and a corresponding decline in the price of the shares. Among them: (i) A change in economic conditions, such as a recession, can adversely affect the price of silver. Silver is used in a wide range of industrial applications, and an economic downturn could have a negative impact on its demand and, consequently, its price and the price of the shares. (ii) A significant change in the attitude of speculators and investors towards silver. Should the speculative community take a negative view towards silver, a decline in world silver prices could occur, negatively impacting the price of the shares. (iii) A significant increase in silver price hedging activity by silver producers. Traditionally, silver producers have not hedged to the same extent as other producers of precious metals (gold, for example) do. Should there be an increase in the level of hedge activity of silver producing companies, it could cause a decline in world silver prices, adversely affecting the price of the shares.

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance Solana LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETF and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETF, option prices may not perfectly replicate the rate of change of the Underlying ETF prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETF declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance Solana LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETF, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETF experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

SOLZ Risks. The Fund invests in instruments based on the value of SOLZ. The Fund is therefore subject to certain of the same risks as if it owned shares of SOLZ, as well as the risks associated with the assets held by SOLZ, even though the Fund does not hold those assets directly. The value of SOLZ will fluctuate with the price of SOL, which is influenced by regulatory developments, technology changes, network adoption, competition, supply/demand dynamics in the Solana ecosystem, investor sentiment and other factors. Brokerage, custody, management fees and other expenses may negatively impact SOLZ’s performance and thereby the value of the Fund’s shares.

Solana Futures Contracts and Rolling Risk. Solana futures are cash-settled instruments with specified expirations, requiring SOLZ to “roll” positions into later-dated contracts as near-month contracts approach expiration. Markets for Solana futures may experience contango (longer-dated contracts priced higher than near-dated contracts) or backwardation (the opposite), either of which can cause the SOLZ’s performance to diverge from the spot price of SOL. In periods of contango—historically pronounced for certain digital-asset futures—SOLZ may incur persistent negative roll yield by selling lower-priced expiring contracts and buying higher-priced later-dated contracts, which can materially depress NAV and total return, particularly when investing in back-month contracts.

  Futures Market and Leverage Risk. Futures trading involves risks that include imperfect correlation with the reference asset; limited secondary-market liquidity; the potential inability to close positions when desired; and losses from unanticipated market movements. Because margin requirements are typically a fraction of the notional value, futures create embedded leverage: small adverse price moves can produce outsized losses (including losses exceeding the amount initially invested in the contract) and require daily variation margin payments at times when SOLZ may have limited cash. Rapid selling to meet margin or risk limits may result in unfavorable execution prices.

  Position Limits, Price Limits, and Market Disruptions. Solana futures are subject to CFTC and exchange-imposed position limits designed to curb excessive speculation, as well as price limits that restrict intraday trading ranges and may halt trading. If limits are reached or if liquidity is otherwise constrained—due to market disruptions, accountability levels, FCM restrictions, or margin changes—SOLZ may be unable to transact in Solana futures as intended. In such circumstances, the Adviser may, in SOLZ’s best interests and subject to then-current facts and circumstances, use Solana-linked instruments other than futures, adjust or suspend creations, require EFRP-based creations/redemptions, apply variable transaction fees, or de-lever the portfolio relative to its investment objective.

  Regulatory and Instrument-Selection Risk. The legal status of digital assets continues to evolve. A judicial or regulatory determination that SOL is a “security” under the federal securities laws could adversely affect SOL’s value and, depending on the circumstances, could require SOLZ to alter operations materially or liquidate. SOLZ may also seek exposure through Solana-linked ETPs, swaps, and other derivatives, each of which entails additional risks— including management fees and tracking differences for ETPs; counterparty and valuation risk for swaps; and potential increases in correlation error versus SOL. Transaction costs, position limits, counterparty availability, and structural features of non-futures instruments can further reduce correlation with SOL and impede achievement of SOLZ’s objective.

SOL Risks. The Fund’s investment strategy, involving indirect exposure to Solana is subject to uncertainties, and potential financial losses. SOL and SOL-related investments are relatively new and subject to unique and substantial risks. SOL has historically been subject to significant price volatility and the value of an investment in the Fund could decline rapidly and significantly. The performance of SOL-related investments, and therefore the performance of the Fund, may differ significantly from the performance of SOL. As with all investments, there is no assurance of profit, and investors should be cognizant of these specific risks associated with SOL and SOL-related investments:

 

  SOL is a relatively new innovation and is subject to unique and substantial risks. SOL operates as a decentralized, peer-to-peer financial trading platform and value storage that is used like money. However, it has no central governmental or banking authority, is not backed by any government and not a legal tender. The markets for SOL and SOL-related Investments may be less liquid and more volatile than other markets for more established products. It may be difficult to execute a SOL trade at a specific price when there is a relatively small volume of buy and sell orders in the SOL market. A market disruption can also make it more difficult to liquidate a position or find a suitable counterparty at a reasonable cost.

 

  The market for SOL is subject to rapid price swings, changes and uncertainty. A significant portion of the demand for SOL may be the result of speculation. The value of SOL has been, and may continue to be, substantially dependent on speculation. Such speculation regarding the potential future appreciation of the price of SOL may artificially inflate or deflate the price of SOL and increase volatility. A significant portion of SOL is held by a small number of holders sometimes referred to as “whales.” Transactions by these holders may influence the price of SOL and these holders may have the ability to manipulate the price of SOL.
     
  The further development of the SOL Network and the acceptance and use of SOL may be subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the SOL Network or the acceptance of SOL may adversely affect the price and liquidity of SOL.

 

  If one or a coordinated group of validators were to gain control of a significant proportion of SOL, they could (depending on the proportion of control gained), impede, reverse or prevent confirmation of transactions, causing a fork in the blockchain that could result in one portion of the network running the pre-modification software and the other portion of the network running the modified software – an event that could negatively impact the value of SOL and in turn the value of the Fund. Gaining such control over the network could also result in manipulation of the blockchain and cast doubt on new SOL transactions on the Solana Network.
     
  SOL is subject to the risk of fraud, theft, manipulation, securities failures, and operational or other problems that impact SOL trading venues. Unlike the exchanges for more traditional assets, such as equity securities and established futures contracts, SOL and SOL trading venues are largely unregulated and may be operating out of compliance with applicable regulation. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote SOL in a way that may artificially increase the price of SOL). Investors may be more exposed to the risk of theft, fraud, market manipulation, and operational failures than when investing in more traditional asset classes. Over the past several years, the Solana Network has reportedly suffered multiple network outages including those arising from software problems, security vulnerabilities, and denial of service and bot attacks. Similarly, software and wallets employed by users and validators to access the Solana Network and transact in SOL may suffer from fraud, theft, disruptions, glitches or other problems negatively impacting the value of SOL and SOL-related Investments. Investors in SOL SOL-related Investments may have little or no recourse should such theft, fraud, manipulation or other problems occur and could suffer significant losses.

 

 

 

Legal or regulatory changes may negatively impact the operation of the Solana Network and Protocol or restrict the use of Solana. For example, if SOL were determined or were expected to be determined to be offered and sold as a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in SOL, trading in SOL-related Investments may become significantly more volatile and/or completely halted, and the value of an investment in the Fund could decline significantly and without warning, including to zero.

 

The realization of any of these risks could result in a decline in the acceptance of SOL and consequently a reduction in the value of SOL, SOL-related Investments, and the Fund.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risks. 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. 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 or the Fund’s other portfolio holdings, 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 reference asset 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. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

Defiance XRP LightningSpread(TM) Income ETF | Options Contracts [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Options Contracts. The use of options contracts involves investment strategies and risks that differ significantly from those associated with ordinary portfolio securities transactions. Options prices are influenced by multiple factors, including changes in the value of the underlying security or index, actual or implied volatility, time remaining until expiration, interest rates, fiscal and monetary policies, and national and international political or economic events. For the Fund, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETF and the specific characteristics of the types of options strategies the Fund employs.

 

Although the Fund may use options to provide synthetic exposure to the Underlying ETF, option prices may not perfectly replicate the rate of change of the Underlying ETF prior to expiration, resulting in potential tracking differences. Similarly, the premiums received from selling put spreads are influenced by market volatility and the specific strike prices selected, which can vary based on market conditions.

 

The Fund may experience downside risk from certain options positions, including the potential for purchased options to expire worthless, resulting in the loss of premiums paid. Writing (selling) options also exposes the Fund to risk of loss, which may exceed the premiums received. For example, selling put options exposes the Fund to the risk that the price of the Underlying ETF declines below the strike price, potentially resulting in substantial losses. Selling put spreads limits these losses to the difference between the strike prices of the sold and purchased puts, less the net premium received, but does not eliminate risk.

 

The Fund may encounter challenges in managing written options positions, particularly in volatile or illiquid markets, where closing or adjusting positions may be difficult or costly. Additionally, the process of rolling options positions, replacing expiring options with new contracts to maintain exposure, can involve significant transaction costs and expose the Fund to additional risks, such as adverse price movements during the roll period or reduced liquidity in the desired contracts. The Fund may also face margin requirements associated with written options, which could require the Fund to liquidate other assets to meet these obligations, potentially at unfavorable prices. Collectively, these risks may result in losses or reduced investment efficiency for the Fund.

 

Defiance XRP LightningSpread(TM) Income ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the Underlying ETF, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. 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 assets, 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 the reference asset.

 

If the Underlying ETF experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

 

Defiance XRP LightningSpread(TM) Income ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 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.

Risk [Text Block]

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed 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 an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

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. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means.

Risk [Text Block]

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

Defiance XRP LightningSpread(TM) Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

 

Defiance XRP LightningSpread(TM) Income ETF | U.S. Government and U.S. Agency Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

 

Defiance XRP LightningSpread(TM) Income ETF | Futures Market and Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Futures Market and Leverage Risk. Futures trading involves risks that include imperfect correlation with the reference asset; limited secondary-market liquidity; the potential inability to close positions when desired; and losses from unanticipated market movements. Because margin requirements are typically a fraction of the notional value, futures create embedded leverage: small adverse price moves can produce outsized losses (including losses exceeding the amount initially invested in the contract) and require daily variation margin payments at times when the Fund may have limited cash. Rapid selling to meet margin or risk limits may result in unfavorable execution prices.

 

Defiance XRP LightningSpread(TM) Income ETF | Position Limits, Price Limits, and Market Disruptions [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Position Limits, Price Limits, and Market Disruptions. XRP futures are subject to CFTC and exchange-imposed position limits designed to curb excessive speculation, as well as price limits that restrict intraday trading ranges and may halt trading. If limits are reached or if liquidity is otherwise constrained—due to market disruptions, accountability levels, FCM restrictions, or margin changes—the Fund may be unable to transact in XRP futures as intended. In such circumstances, the Adviser may, in the Fund’s best interests and subject to then-current facts and circumstances, use XRP-linked instruments other than futures, adjust or suspend creations, require EFRP-based creations/redemptions, apply variable transaction fees, or de-lever the portfolio relative to its investment objective.

 

Defiance XRP LightningSpread(TM) Income ETF | Regulatory and Instrument-Selection Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Regulatory and Instrument-Selection Risk. The legal status of digital assets continues to evolve. A judicial or regulatory determination that XRP is a “security” under the federal securities laws could adversely affect XRP’s value and, depending on the circumstances, could require the Fund to alter operations materially or liquidate. The Fund may also seek exposure through XRP-linked ETPs, swaps, and other derivatives, each of which entails additional risks— including management fees and tracking differences for ETPs; counterparty and valuation risk for swaps; and potential increases in correlation error versus XRP. Transaction costs, position limits, counterparty availability, and structural features of non-futures instruments can further reduce correlation with XRP and impede achievement of the Fund’s objective.

 

Defiance XRP LightningSpread(TM) Income ETF | Liquidity, Counterparty, and Clearing Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Liquidity, Counterparty, and Clearing Risks. The XRP futures market may experience periods of limited liquidity, during which it could be difficult or impossible to enter, liquidate, or adjust positions at reasonable prices or sizes. The Fund is exposed to the credit and operational risks of futures commission merchants and clearinghouses; an FCM or clearinghouse failure, shortfall, or non-compliance with segregation rules could result in loss of posted margin and unrealized gains and prolonged recovery periods. Centrally cleared derivatives concentrate risk in a small number of clearing entities, and applicable resolution regimes could impair the Fund’s ability to exercise remedies or realize on collateral.

 

Defiance XRP LightningSpread(TM) Income ETF | Operational, Trading, and Market Structure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Operational, Trading, and Market Structure Risks. Active management, frequent rolling of futures, and rebalancing activity may increase transaction costs, contribute to market impact, and lead to tracking differences or underperformance. Shares may trade at a premium or discount to NAV, particularly during market stress or when AP or market-maker participation is limited, widening bid-ask spreads and impairing secondary-market liquidity. Additional risks applicable to the Fund’s operations include valuation risk (for instruments priced other than by quoted market trades), new-fund risk, non-diversification risk, cybersecurity and other operational risks, the use of reverse repurchase agreements and collateral investments (with associated interest-rate and credit risks), and potential tax risks related to the Fund’s structure and its use of a controlled foreign subsidiary to obtain futures exposure.

 

Defiance XRP LightningSpread(TM) Income ETF | XRPI Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

XRPI Risks. The Fund invests in instruments based on the value of XRPI. The Fund is therefore subject to certain of the same risks as if it owned shares of XRPI, as well as the risks associated with the assets held by XRPI, even though the Fund does not hold those assets directly. The value of XRPI will fluctuate with the price of XRP, which is influenced by regulatory developments, technology changes, network adoption, competition, supply/demand dynamics in the XRP ecosystem, investor sentiment and other factors. Brokerage, custody, management fees and other expenses may negatively impact XRPI’s performance and thereby the value of the Fund’s shares.

 

Defiance XRP LightningSpread(TM) Income ETF | XRP Futures Contracts and Rolling Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  XRP Futures Contracts and Rolling Risk. XRP futures are cash-settled instruments with specified expirations, requiring the Fund to “roll” positions into later-dated contracts as near-month contracts approach expiration. Markets for XRP futures may experience contango (longer-dated contracts priced higher than near-dated contracts) or backwardation (the opposite), either of which can cause the Fund’s performance to diverge from the spot price of XRP. In periods of contango—historically pronounced for certain digital-asset futures—the Fund may incur persistent negative roll yield by selling lower-priced expiring contracts and buying higher-priced later-dated contracts, which can materially depress NAV and total return, particularly when investing in back-month contracts.

 

Defiance XRP LightningSpread(TM) Income ETF | XRP Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

XRP Risks. The Fund’s investment strategy, involving indirect exposure to XRP is subject to uncertainties, and potential financial losses. XRP and XRP-related investments are relatively new and subject to unique and substantial risks. XRP has historically been subject to significant price volatility and the value of an investment in the Fund could decline rapidly and significantly. The performance of XRP-related investments, and therefore the performance of the Fund, may differ significantly from the performance of XRP. As with all investments, there is no assurance of profit, and investors should be cognizant of these specific risks associated with XRP and XRP-related investments:

 

  XRP is a relatively new innovation and is subject to unique and substantial risks. XRP operates as a decentralized, peer-to-peer financial trading platform and value storage that is used like money. However, it has no central governmental or banking authority, is not backed by any government and not a legal tender. The markets for XRP and XRP-related Investments may be less liquid and more volatile than other markets for more established products. It may be difficult to execute a XRP trade at a specific price when there is a relatively small volume of buy and sell orders in the XRP market. A market disruption can also make it more difficult to liquidate a position or find a suitable counterparty at a reasonable cost.

 

 

 

 

The market for XRP is subject to rapid price swings, changes and uncertainty. A significant portion of the demand for XRP may be the result of speculation. The value of XRP has been, and may continue to be, substantially dependent on speculation. Such speculation regarding the potential future appreciation of the price of XRP may artificially inflate or deflate the price of XRP and increase volatility. A significant portion of XRP is held by a small number of holders sometimes referred to as “whales.” Transactions by these holders may influence the price of XRP and these holders may have the ability to manipulate the price of XRP.

 

  The further development of the XRP Network and the acceptance and use of XRP may be subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the XRP Network or the acceptance of XRP may adversely affect the price and liquidity of XRP.

 

 

If one or a coordinated group of validators were to gain control of a significant proportion of XRP, they could (depending on the proportion of control gained), impede, reverse or prevent confirmation of transactions, causing a fork in the blockchain that could result in one portion of the network running the pre-modification software and the other portion of the network running the modified software – an event that could negatively impact the value of XRP and in turn the value of the Fund. Gaining such control over the network could also result in manipulation of the blockchain and cast doubt on new XRP transactions on the XRP Network.

 

  XRP is subject to the risk of fraud, theft, manipulation, securities failures, and operational or other problems that impact XRP trading venues. Unlike the exchanges for more traditional assets, such as equity securities and established futures contracts, XRP and XRP trading venues are largely unregulated and may be operating out of compliance with applicable regulation. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote XRP in a way that may artificially increase the price of XRP). Investors may be more exposed to the risk of theft, fraud, market manipulation, and operational failures than when investing in more traditional asset classes. Over the past several years, the XRP Network has reportedly suffered multiple network outages including those arising from software problems, security vulnerabilities, and denial of service and bot attacks. Similarly, software and wallets employed by users and validators to access the XRP Network and transact in XRP may suffer from fraud, theft, disruptions, glitches or other problems negatively impacting the value of XRP and XRP-related Investments. Investors in XRP XRP-related Investments may have little or no recourse should such theft, fraud, manipulation or other problems occur and could suffer significant losses.

 

  Legal or regulatory changes may negatively impact the operation of the XRP Network and Protocol or restrict the use of XRP. For example, if XRP were determined or were expected to be determined to be offered and sold as a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in XRP, trading in XRP-related Investments may become significantly more volatile and/or completely halted, and the value of an investment in the Fund could decline significantly and without warning, including to zero.

 

The realization of any of these risks could result in a decline in the acceptance of XRP and consequently a reduction in the value of XRP, XRP-related Investments, and the Fund.

Risk [Text Block]

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
