| Affiliated Index Provider Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Affiliated Index Provider Risk: The Adviser also serves as the Fund’s Index Provider, which may present a potential conflict of interest. For example, a potential conflict could arise if the Adviser were to exercise undue influence with respect to regular and/or extraordinary updates to the methodology or composition of the Underlying Index, including in a manner that might improve the apparent performance of the Fund relative to the performance of the Underlying Index. Additionally, potential conflicts could arise to the extent that portfolio managers of the Adviser become aware of contemplated methodology changes or rebalance activity prior to disclosure to the public, which could facilitate “front running” on behalf of other funds managed by the Adviser with similar exposure. Although the Adviser has taken steps designed to ensure that these potential conflicts are mitigated (e.g., via the adoption of policies and procedures that are designed to minimize potential conflicts of interest and ensure independence with respect to the operation of the Underlying Index, as well as the implementation of informational barriers designed to minimize the potential for the misuse of information about the Underlying Index), there can be no assurance that such measures will be successful.

| Asset Class Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset Class Risk: Securities and other assets in the Underlying Index or otherwise held in the Fund's portfolio may underperform in comparison to the general securities markets, a particular securities market or other asset classes. Depositary Receipts Risk: The Fund may invest in depositary receipts, such as ADRs and GDRs. Depositary receipts may be subject to certain of the risks associated with direct investments in the securities of foreign companies. For additional details on these risks, please see Foreign Securities Risk. Moreover, depositary receipts may not track the price of the underlying foreign securities on which they are based. A holder of depositary receipts may also be subject to fees and the credit risk of the financial institution acting as depositary. Equity Securities Risk: Equity securities are subject to changes in value, and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

| Associated Risks Related To Investing In AI Semiconductor And Semiconductor Equipment Companies Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Associated Risks Related to Investing in AI Semiconductor and Semiconductor Equipment Companies: Companies involved in developing artificial intelligence (“AI”) infrastructure and related products and hardware that rely heavily on technological advances are vulnerable to rapid changes in product cycles, rapid product obsolescence, supply chain disruptions, government regulation, and competition, both domestically and internationally. Companies involved in the semiconductors and semiconductor equipment industry face increased risk from trade agreements between countries that develop these technologies and countries in which customers of these technologies are based. The success of such companies frequently depends on the ability to develop and produce competitive new semiconductor technologies. Companies in this industry frequently undertake substantial research and development expenses in order to remain competitive, and a failure to successfully demonstrate advanced functionality and performance can have a material impact on the company’s business.

| Associated Risks Related To Investing In Quantum Computing Companies Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Associated Risks Related to Investing in Quantum Computing Companies: Quantum computing is an emerging industry characterized by early-stage development. Companies in this industry may have limited operating histories, minimal revenues, and uncertain prospects for profitability. Valuations of quantum computing companies may be based more on speculative potential than on current financial performance, which can lead to elevated volatility and the risk of significant losses. In addition, quantum computing companies may be exposed to risk due to rapid technological change, intense competition, consumer demand, shifts in government funding, evolving regulatory frameworks, and export control restrictions. As a result, the Fund’s exposure to quantum computing companies may cause it to experience greater price volatility and an increased risk of loss compared to funds that do not invest in this industry.
|
| Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capitalization Risk: Investing in issuers within the same market capitalization category carries the risk that the category may be out of favor due to current market conditions or investor sentiment. Large-Capitalization Companies Risk: Large-capitalization companies may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better - or worse - than the stock market in general. These periods have, in the past, lasted for as long as several years. Mid-Capitalization Companies Risk: Mid-capitalization companies may have greater price volatility, lower trading volume and less liquidity than large-capitalization companies. In addition, mid-capitalization companies may have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than large-capitalization companies. Small-Capitalization Companies Risk: Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid.

|
| Currency Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk: The Fund may invest in securities denominated in foreign currencies. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the currencies of the underlying securities depreciate against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning, which could have a significant negative impact on the Fund.
|
| Custody Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Custody Risk: The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund's custodian. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.
|
| Cybersecurity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk: With the increased use of technologies such as the Internet to conduct business, the Fund, like all companies, may be susceptible to operational, information security and related risks. Cybersecurity incidents involving the Fund and its service providers (including, without limitation, the Adviser, fund accountant, custodian, transfer agent and financial intermediaries) have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, impediments to trading, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages, governmental and other regulatory authorities, exchanges and other financial market operators, banks, brokers, dealers, insurance companies, other financial institutions and other parties. The Fund and its shareholders could be negatively impacted as a result.
|
| Focus Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Focus Risk: To the extent that the Underlying Index focuses in investments related to a particular industry or group of industries, the Fund will also focus its investments to approximately the same extent. Similarly, if the Underlying Index has significant exposure to one or more sectors, the Fund’s investments will likely have significant exposure to such sectors. In such event, the Fund’s performance will be particularly susceptible to adverse events impacting such industry or sector, which may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular industry or sector. As a result, the value of the Fund’s investments may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries or sectors. Risks Related to Investing in the Information Technology Sector: The AI Semiconductor companies in which the Fund invests are a subset of the Information Technology sector. Companies in the information technology sector are subject to rapid changes in technology product cycles; rapid product obsolescence; government regulation; and increased competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies and companies that rely heavily on technology tend to be more volatile than the overall market and also are heavily dependent on patent and intellectual property rights. In addition, information technology companies may have limited product lines, markets, financial resources or personnel. Risks Related to Investing in the Semiconductors and Semiconductor Equipment Industry: The semiconductors and semiconductor equipment industry is highly competitive, and certain companies in this industry may be restricted from operating in certain markets due to the sensitive nature of these technologies. Companies in this space generally seek to increase silicon capacity, improve yields, and reduce die size in their product designs which may result in significant increases in worldwide supply and downward pressure on prices. Companies involved in the semiconductors and semiconductor equipment industry face increased risk from trade agreements between countries that develop these technologies and countries in which customers of these technologies are based. Lack of resolution or potential imposition of trade tariffs may hinder the companies’ ability to successfully deploy their inventories. The success of such companies frequently depends on the ability to develop and produce competitive new semiconductor technologies. Companies in this industry frequently undertake substantial research and development expenses in order to remain competitive, and a failure to successfully demonstrate advanced functionality and performance can have a material impact on the company’s business.

| Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk: The Fund may invest, within U.S. regulations, in foreign securities. The Fund's investments in foreign securities can be riskier than U.S. securities investments. Investments in the securities of foreign issuers (including investments in American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. The prices of foreign securities and the prices of U.S. securities have, at times, moved in opposite directions. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges could be affected by, among other factors, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. The Fund may lose money due to political, economic and geographic events affecting a foreign issuer or market. Where all or a portion of the Fund's underlying securities trade in a market that is closed when the market in which the Fund's Shares are listed and trading is open, there may be differences between the last quote from the security’s closed foreign market and the value of the security during the Fund’s domestic trading day. This, in turn, could lead to differences between the market price of the Fund’s Shares and the underlying value of those shares.
|
| Geographic Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Risk: A natural, biological or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region or in a region economically tied to the affected region. The securities in which the Fund invests and, consequently, the Fund are also subject to specific risks as a result of their business operations, including, but not limited to: Risk of Investing in Developed Markets: The Fund’s investment in a developed country issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities. Risk of Investing in Emerging Markets: Investments in emerging markets may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries, and there may be greater risk associated with the custody of securities in emerging markets. It may be difficult or impossible for the Fund to pursue claims against an emerging market issuer in the courts of an emerging market country. There may be significant obstacles to obtaining information necessary for investigations into or litigation against emerging market companies and shareholders may have limited legal rights and remedies. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets may also face other significant internal or external risks, including the risk of war, terrorism, or other social or political conflicts. Emerging market economies’ exposure to specific industries, such as tourism, and lack of efficient or sufficient health care systems, could make these economies especially vulnerable to global crises. Certain emerging market countries may have privatized, or have begun the process of privatizing, certain entities and industries. Privatized entities may lose money or be re-nationalized. Risk of Investing in Taiwan: Investments in Taiwanese issuers involve risks that are specific to Taiwan, including legal, regulatory, political and economic risks. Political and economic developments of Taiwan’s neighbors may have an adverse effect on Taiwan’s economy. Specifically, Taiwan’s geographic proximity and history of political contention with China have resulted in ongoing tensions, which may materially affect the Taiwanese economy and its securities market. Risk of Investing in the United States: A decrease in imports or exports, changes in trade regulations and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy.

|
| Indexing Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Indexing Strategy Risk: The Fund is not actively managed, and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not seek to outperform its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Additionally, if a constituent of the Underlying Index were removed, even outside of a regular rebalance of the Underlying Index, the Adviser anticipates that the Fund would sell such security. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy. Index-Related Risk: There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Management Risk: The Fund may not fully replicate its Underlying Index and may hold securities not included in its Underlying Index. The Adviser’s investment strategy, the implementation of which is subject to a number of constraints, may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective. Tracking Error Risk: Tracking error may occur because of differences between the instruments held in the Fund's portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund's holding of uninvested cash, size of the Fund, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

|
| International Closed Market Trading Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | International Closed Market Trading Risk: To the extent that the underlying investments held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s Shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other exchange-traded funds ("ETFs").
|
| Issuer Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of such company's securities to decline.
|
| Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk: Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. If the securities held by the Fund experience poor liquidity, the Fund may be unable to transact at advantageous times or prices, which may decrease the Fund’s returns. In addition, there is a risk that policy changes by central governments and governmental agencies, including the U.S. Federal Reserve or the European Central Bank, which could include increasing interest rates, could cause increased volatility in financial markets and lead to higher levels of Fund redemptions from Authorized Participants, which could have a negative impact on the Fund. Beginning in early 2025, the U.S. government’s threats to impose tariffs on goods from Mexico and Canada has heightened tension among trading partners. Further, in response to the U.S. government’s announcement of tariffs on goods from China, the Chinese government has countered with tariffs on U.S. goods, marking the beginning of a potential trade war between the countries. Tariffs on imported goods may increase the cost of certain products and household items, which may in turn dampen consumer spending and result in decreased confidence in the markets. The possibility of additional tariffs being imposed or the outbreak of a trade war may further adversely impact U.S. and international markets. Additionally, political uncertainty regarding U.S. policy, including the U.S. government’s approach to trade, may also impact the markets. Furthermore, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, raising of interest rates, or other events could have a significant impact on the Fund and its investments and trading of its Shares. This increases the risk that monetary policy may provide less support should economic growth slow. Market risk factors may result in increased volatility and/or decreased liquidity in the securities markets. The Fund’s NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.
|
| New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk: The Fund is a new fund, with no operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. While shareholder interests will be the paramount consideration, the timing of any liquidation may not be favorable to certain individual shareholders. New funds are also subject to Large Shareholder Risk.
|
| Operational Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk: The Fund is exposed to operational risk arising from a number of 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. Additionally, cyber security failures or breaches of the electronic systems of the Fund, the Adviser, and the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate for those risks that they are intended to address.
|
| Risks Associated With Exchange-Traded Funds Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risks Associated with Exchange-Traded Funds: As an ETF, the Fund is subject to the following risks: Authorized Participants Concentration Risk: The Fund has a limited number of financial institutions that may act as Authorized Participants and engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. To the extent that those Authorized Participants exit the business or are unable to process creation and/or redemption orders, such as in times of market stress, Shares may be more likely to trade at a premium or discount to NAV and/or at wider intraday bid-ask spreads, and possibly face trading halts and/or delisting from an exchange. Authorized Participants Concentration Risk may be heightened because the Fund invests in non-U.S. securities. Large Shareholder Risk: Redemptions by large shareholders could have a significant negative impact on the Fund. If a large shareholder were to redeem all, or a large portion, of its Shares, there is no guarantee that the Fund will be able to maintain sufficient assets to continue operations in which case the Board of Trustees may determine to liquidate the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on a national securities exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. Listing Standards Risk: The Fund is required to comply with listing requirements adopted by the listing exchange. Non-compliance with such requirements may result in the Fund's shares being delisted by the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders. Market Trading Risks and Premium/Discount Risks: Shares of the Fund are publicly traded on a national securities exchange, which may subject shareholders to numerous market trading risks. In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares, as well as disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of assets in the Fund or an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund’s Shares fluctuates, in some cases materially, throughout trading hours in response to changes in the Fund’s NAV.

| Risk [Text Block] | Market Trading Risks and Premium/Discount Risks: Shares of the Fund are publicly traded on a national securities exchange, which may subject shareholders to numerous market trading risks. In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares, as well as disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of assets in the Fund or an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund’s Shares fluctuates, in some cases materially, throughout trading hours in response to changes in the Fund’s NAV.

| Risk [Text Block] | Trading Halt Risk: An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology (such as during trading halts). The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, the Adviser or any of its affiliates. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940 ("1940 Act"). As a result, the Fund is subject to the risk that it may be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.
