|---|---|---|---|---|
| Equity Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Equity Market Risk. 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 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.
|
|||
| Focused Portfolio Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively focused portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments.
|
|||
| Photonics Companies Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Photonics Companies Risk. “Photonics Companies” include companies involved in the development, manufacture, supply, or commercialization of technologies, products, components, materials, or services related to photonics, including Co-Packaged Optics (“CPO”), External Light Source (“ELS”) architecture, and the enabling technologies and components that support such systems. Photonics Companies may be subject to rapid changes in technology, intense competition, government regulation, and obsolescence risk. Securities of such companies may be subject to greater price volatility than securities of companies in other sectors, particularly over the short term. The prices of securities of companies in these industries may fluctuate widely due to competitive pressures, rapid product cycles, changes in the regulatory environment, and shifts in supply and demand dynamics. Many Photonics Companies are relatively small and may have limited product lines, markets, financial resources, or personnel, making them more susceptible to business risks and adverse developments. Photonics Companies may also be dependent upon government contracts or subsidies, which may be subject to cancellation, renegotiation, or delay in payment. Additionally, the development and commercialization of photonic and optical technologies may be contingent upon the broader adoption of related technologies, including artificial intelligence, data center infrastructure, and advanced telecommunications networks. A slowdown or disruption in the growth of these related sectors could materially and adversely affect the revenues and profitability of Photonics Companies in which the Fund invests.
|
|||
| Index Strategy Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Index Strategy Risk. The Fund’s strategy is linked to an Index maintained by the Index Provider that exercises complete control over the Index. The Index Provider may delay or add a rebalance date, which may adversely impact the performance of the Fund and its correlation to the Index. In addition, there is no guarantee that the methodology used by the Index Provider to identify constituents for the Index will achieve its intended result or positive performance. Errors in Index data, Index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and/or corrected for a period of time or at all, which may have an adverse impact on the Fund.
|
|||
| Data Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Data Risk. The composition of the Index is heavily dependent on information and data supplied by third parties (“Data”). When Data proves to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors.
|
|||
| Passive Investment Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.
|
|||
| Tracking Error Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Tracking Error Risk. While the Fund generally seeks to track the performance, before fees and expenses, of the Index, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.
|
|||
| 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 to the extent the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries.
|
|||
| Semiconductor Companies Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Semiconductor Companies Risk. The semiconductor industry is characterized by rapid technological change and product obsolescence, cyclical market patterns, price erosion, periods of over-capacity and production shortages, variations in manufacturing costs and yields, and significant expenditures for capital equipment and product development. Semiconductor companies depend significantly on third-party suppliers and the availability of raw materials and may be adversely affected by supply chain disruptions. They also may be adversely affected by the loss or impairment of intellectual property rights.
|
|||
| Management Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Management Risk. The risk that the investment techniques and risk analyses applied by the investment adviser will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to the investment adviser and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved. |

|||
| Foreign Investment Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Foreign Investment Risk. The Fund may invest in foreign companies. Such investments involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.
|
|||
| Risks Related to Changes in Government Policies and Institutions [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Risks Related to Changes in Government Policies and Institutions. The U.S. government has recently made, and may continue to make from time to time, significant changes to established, and in some cases longstanding, policies and institutions of the United States federal government, including the restructuring of the United States’ trade relationships, imposition of tariffs on products imported from foreign markets, reducing government investment, and downsizing or dismantling of government agencies. Such changes may have immediate and/or longstanding effects on the economies of the United States, its trade partners, and/or its allies. There could be a wide range of consequences that are difficult or impossible to predict from such actions. Such consequences may include a decrease in regulatory oversight of certain highly regulated industries (banking, financial services, data security, drug and medical device development, and energy), an increase in regulatory backlog leading to significantly slower regulatory approval processes, uncertainty with respect to the authority of certain agencies or their personnel, the inability of the federal government and its agencies to maintain the security of personal data of United States citizens and/or of other digital assets. The business and prospects of companies that do business with the government or which rely on government funding may be materially and adversely affected. This may include the Fund and/or prospective issuers held in the Fund’s investment portfolio.
|
|||
| Derivatives Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. 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. |
|||
| Options Contracts [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund’s options contracts are exercised or expire it may enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.
|
|||
| 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.
Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.

| Equity Total Return Swaps [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Equity Total Return Swaps. A total return swap (also sometimes referred to as a synthetic equity swap or “contract for difference” when written with respect to an equity security or basket of equity securities) is an agreement between two parties under which the parties agree to make payments to each other so as to replicate the economic consequences that would apply had a purchase or short sale of the underlying reference instrument or index thereof taken place. For example, one party agrees to pay the other party the total return earned or realized on the notional amount of an underlying equity security and any dividends declared with respect to that equity security. In return the other party makes payments, typically at a floating rate, calculated based on the notional amount.
|
|||
| Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery. Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | ETF Risks
|
|||
| 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.
|
|||
| 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

|
|||
| 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 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.
|
|||
| Liquidity Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Liquidity Risk. In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.
|
|||
| Economic and Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| 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 [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings as it seeks to track the Index. 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.
|
|||
| Liquidity Risk 1 [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.
|
|||
| Money Market Instrument Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. 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.
|
|||
| New Fund Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.
|
|||
| Operational Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
|
|||
| Newly Public Company Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Newly Public Company Risk. The Fund may obtain exposure to publicly traded companies that have recently completed an initial public offering (“IPO”), as well as operating companies resulting from completed SPAC business combinations, to the extent such companies are included in the Index. Companies that have recently become publicly traded may be unseasoned and may have limited trading histories, track records of reporting to investors, and research coverage. Their securities may experience significant price volatility and may be subject to greater liquidity risk. In addition, significant holdings by venture capital, private equity or other pre-public investors may become eligible for sale following the expiration of applicable lock-up periods, which may result in increased volatility or downward pressure on the market price of such securities.
|
|||
| Warrants and Rights Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Warrants and Rights Risk. The Fund may receive or invest in warrants or rights in connection with its purchase of equity securities, including SPAC units. Warrants and rights do not represent an ownership interest in the issuer but instead confer the right to purchase underlying securities at a specified price, subject to the terms of the instrument. Accordingly, holders of warrants or rights generally do not have voting rights, receive dividends, or have rights with respect to the assets of the issuer. Investments in warrants and rights are speculative and involve a high degree of risk. The value of warrants and rights may be highly volatile and may not move in tandem with the value of the underlying securities. In addition, warrants and rights are complex financial instruments, and their accounting treatment and valuation involve significant judgment. For example, depending on their terms and the specific facts and circumstances of the issuer, warrants may be classified as equity or as assets or liabilities of the issuer, which can affect their valuation and increase the risk of error. Warrants and rights are also subject to the risk that they may expire worthless if not exercised or sold prior to expiration. In addition, the effective cost of acquiring the underlying securities upon exercise (i.e., the purchase price of the warrant or right plus the exercise price) may exceed the market value of the underlying securities at the time of exercise. With respect to SPAC-related investments, if a SPAC does not complete a business combination within the specified time period, any associated warrants or rights held by the Fund may expire worthless.
|
|||
| 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 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 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.
|
|||
| Underlying Index Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Underlying Index Risk. Neither the Fund’s investment adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Index. The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.
|
|||
| Risk Lose Money [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. | |||
| Risk Nondiversified Status [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a 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.
