| Active Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk: The Fund is actively managed using the Adviser’s proprietary investment strategies and processes and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the Adviser will use its judgment and sole discretion to apply investment techniques and risk analyses that may not operate as intended or produce the desired result. In addition, while the Adviser will use the Reference Index to serve as an initial set of potential SMR Companies, there may be periods of time where the Fund’s holdings, and therefore its performance, will deviate significantly from the holdings and performance of the Reference Index. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective, and the Adviser’s investment decisions may cause the Fund to underperform other funds with a similar investment objective.

| Asset Class Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset Class Risk: Securities and other assets 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 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. Depositary receipts are generally subject to the same risks associated with direct investments in the securities of foreign companies. A holder of depositary receipts may also be subject to fees and the credit risk of the financial institution acting as depositary. Unsponsored depositary receipts may involve higher expenses, fewer shareholder rights, and may be less liquid. Derivatives Risk: The Fund will invest in derivative instruments. Derivatives (e.g., options, futures contracts, forwards, swaps) are instruments the value of which is derived from that of other assets, rates, or indices. Derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses for the Fund. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives are usually traded on margin, which may subject the Fund to margin calls. Margin calls may force the Fund to liquidate assets. Further, the market for certain derivatives may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. If the Fund needed to sell a large block of illiquid securities to meet shareholder redemption request or to raise cash, these sales could further reduce the securities’ prices and adversely affect performance of the Fund. 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 a company’s business performance, investor perceptions, stock market trends and general economic conditions. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. U.S. Treasury obligations are subject to inflation risk, as the price of short term U.S. Treasury obligations tends to fall during inflationary periods as investors seek higher yielding investments. Changes to interest rates may also adversely affect the value and liquidity of the U.S. Treasury obligations. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's investments in U.S. Treasury obligations to decline. Notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative "debt ceiling," which can in turn drive debt higher. Such non-payment could result in losses to the Fund and substantial negative consequences for the U.S. economy and the global financial system.

| Asset Class Risk, U.S. Treasury Obligations Risk Member | |

|
| Associated Risks Related To Investing In SMR Companies Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Associated Risks Related to Investing in SMR Companies: The Fund invests in SMR Companies, which are companies that are involved in the design, development, licensing, manufacture, and construction of small modular reactors (“SMRs”) and other smaller-sized nuclear reactors, together with the specialized fuel, components, and technology on which they depend. The development, licensing, production, and manufacturing of SMRs is subject to rapid changes in technology, intense competition, supply chain disruption, government regulation, and shifts in consumer sentiment toward such companies. Rapid changes to the regulatory environment and/or product obsolescence could have a material adverse effect on a company’s operating results. Securities of SMR Companies may be subject to greater price volatility than securities of companies involved in other business activities, particularly over the short term, due to competitive pressures, cyclical demand patterns, changes in the regulatory environment, and shifts in supply and demand dynamics. As a result, investments in SMR Companies may be subject to higher levels of risk and volatility. SMR Companies may need to engage in significant capital expenditures to establish or maintain business lines and may experience significant delays in generating revenue. There can be no guarantee that these expenditures will stabilize or that the companies will be profitable, which may adversely affect the Fund’s investment in those companies. Further, SMR Companies may face high operating costs and maintenance expenses, which may adversely affect a company’s ability to further develop or grow related product lines. Additionally, certain companies included in the Fund’s portfolio may be engaged in other lines of business unrelated to the development of SMRs, and these lines of business could adversely affect their operating results despite a company’s possible success in activities linked to SMR lines of business.
|
| 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. 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. These securities may have returns that vary, sometimes significantly, from the overall securities market. Small-Capitalization Companies Risk: Small-capitalization companies may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid than large- and mid-capitalization companies. In addition, small-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 shorter operating histories than large- and mid-capitalization companies. These securities may have returns that vary, sometimes significantly, from the overall securities market.

These securities may have returns that vary, sometimes significantly, from the overall securities market.
|
| Cash Transaction Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transaction Risk: Unlike most exchange-traded funds ("ETFs"), the Fund intends to effect a significant portion of creations and redemptions for cash, rather than through in-kind delivery of portfolio securities, which may cause the Fund to incur certain costs it might not otherwise incur if the Fund effected its creations and redemptions primarily in-kind. As such, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve the Fund recognizing a capital gain and/or incurring considerable brokerage fees and taxes that the Fund would not have incurred if it had made its redemptions in-kind. These factors may result in wider spreads between the bid and the offered prices of the Fund’s Shares than would be the case for more conventional ETFs. To the extent that these brokerage costs or taxable gains or losses are not offset by the transaction fee payable by an Authorized Participant in connection with the purchase or redemption of Creation Units, such costs will be borne by the Fund and could decrease the Fund’s net asset value.
|
| Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk: Counterparty risk is the risk that a counterparty to a swap contract or other similar investment instrument may be unwilling or unable to make timely payments or otherwise meet its contractual obligations. A counterparty’s failure to fulfill its contractual obligations, whether due to financial insolvency or operational constraints, could result in substantial losses for the Fund or negatively impact Fund performance. In such an instance, the Fund may experience significant delays in obtaining any recovery, may obtain only a limited recovery, or may obtain no recovery at all. Even if the counterparty does not default, any perception of heightened counterparty risk could impair the liquidity and valuation of the investments held by the Fund. There may be limited counterparties available and the Fund’s reliance on a limited number of counterparties for these transactions may increase the Fund’s exposure to counterparty risk. Specifically, the Fund may have sole or substantial exposure to one counterparty, which may result in the Fund being more susceptible to concentrated counterparty 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, which may cause the Fund to experience difficulty in purchasing or selling certain instruments in a timely manner. If the Fund is unable to obtain the desired exposure from counterparties, or can do so only on unfavorable terms, the Fund may not be able to achieve its investment objective, may be unable to rebalance its portfolio as intended, or may experience increased costs, any of which could result in significant losses to the Fund or negatively impact Fund performance.
|
| 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 currencies of the underlying securities depreciate against the U.S. dollar or if there are delays or limits on repatriation of such currencies. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund's NAV. Exchange rates may be volatile and 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: Custody risk refers to the risks in the process of clearing and settling trades, as well as the holding of securities and other assets by local banks, agents, and securities depositories. These risks are heightened in jurisdictions with less developed markets or less robust settlement and custody infrastructure and processes.
|
| 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. |
| Focus Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Focus Risk: The Fund may be susceptible to an increased risk of loss, including losses due to events that adversely affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are focused in the securities of a particular issuer or issuers within the same market, asset class, industry, group of industries, or one or more sectors. In such event, the Fund’s performance will depend to a greater extent on the overall condition of such market, asset class, industry(ies) or sector(s), and an economic, business, political, regulatory, or other occurrence affecting these such market, asset class, industry(ies) or sector(s) will have an increased impact on the value of the Fund’s shares compared to the value of shares of a fund that invests more broadly. Risks Related to Investing in the Electrical Equipment Industry: The Electrical Equipment Industry is fragmented but includes a number of large incumbent companies that may compete heavily for market share in the space. Companies in the Electrical Equipment Industry may involve operations with high fixed costs. Because copper, aluminum, steel and other raw materials are often critical components of the products manufactured in the Electrical Equipment Industry, fluctuations in commodities prices for such raw materials may impact the profitability of companies in this industry. Purchasers of such products may be geographically dispersed, which may subject companies in this industry to any increases in geopolitical uncertainty or global macroeconomic trends. Risks Related to Investing in the Industrials Sector: Companies in the industrials sector are subject to fluctuations in supply and demand for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrials sector. Companies also may be adversely affected by environmental damage and product liability claims. Also, commodity price volatility, changes in exchange rates, imposition of import controls or tariffs, increased competition, depletion of resources, technological developments and labor relations could adversely affect the companies in this sector. Risks Related to Investing in the Utilities Sector: Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization and deregulation in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities sector may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets. In addition, companies in the utilities sector may be adversely affected due to increase in fuel and operating costs and the costs of complying with regulations. Furthermore, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.

| Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk: 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 additional risks, including lower levels of liquidity and market efficiency; greater securities price volatility; exchange rate fluctuations and exchange controls; less availability of public information about issuers; limitations on foreign ownership of securities; imposition of withholding or other taxes; imposition of restrictions on the expatriation of the assets of the Fund; restrictions placed on U.S. investors by U.S. regulations governing foreign investments; higher transaction and custody costs and delays in settlement procedures; difficulties in enforcing contractual obligations; lower levels of regulation of the securities market; weaker accounting, disclosure and reporting requirements; and legal principles relating to corporate governance and directors’ fiduciary duties and liabilities. The countries in which the Fund invests may also be subject to structural risks, including economic, political and social instability. Additionally, certain securities held by the Fund, while traded on U.S. exchanges, may be issued by foreign financial institutions and as such, may be subject to the risks of investing in securities issued by foreign companies, which may not be subject to the same regulations as companies domiciled in the U.S. Where all or a portion of the Fund's 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: The Fund’s investments in securities of issuers located in a particular country or geographic region may subject the Fund to certain risks to a greater extent than if its investments were less focused, including: natural, biological or other disasters and the spread of infectious diseases; economic, political and social instability; security concerns; and trade disputes with key trading partners. The securities in which the Fund invests and, consequently, the Fund is also subject to specific risks as a result of their business operations in a particular country or region, including, but not limited to: China Exposure Risk: Due to its investment strategy, the Fund may, at times, be exposed to risks related to investing in China. China may be subject to considerable degrees of economic, political and social instability. Concerns about the rising government and household debt levels could impact the stability of the Chinese economy. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices, including recent reforms to liberalize its capital markets and expand the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Risk of Investing in Developed Markets: Investments in a developed country’s issuer may subject the Fund to legal, regulatory, political, currency, security, and economic risks specific to 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 war, 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 adversely 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. Risk of Investing in Hong Kong: Investments in Hong Kong securities may subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Hong Kong. Hong Kong’s economy and political environment are closely tied to those of China, which is Hong Kong’s largest trading partner for exports and imports. Changes in China’s economy, market or policies, or a tightening of China’s control over Hong Kong, may have an adverse impact on Hong Kong’s economy. 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: Investments in United States issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks specific to the United States. A decrease in imports or exports, changes in trade regulations, inflation and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy.

A decrease in imports or exports, changes in trade regulations, inflation and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy.
|
| 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").
|
| Investable Universe Of Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investable Universe of Companies Risk: The investable universe of companies to which the Fund may seek economic exposure may be limited. If a company no longer satisfies the criteria used to determine the Fund’s investable universe, the Fund may need to reduce or eliminate its exposure to that company. The reduction or elimination of the Fund’s exposure to a company may have an adverse impact on the liquidity of the Fund’s overall portfolio holdings and on Fund performance. In addition, because the Fund may obtain economic exposure to a limited number of issuers, the Fund is subject to the risk that the value of its portfolio may decline as a result of a decline in the value of the Fund’s exposure to a particular issuer. The Fund’s economic exposure to an issuer may decline in value for reasons directly related to that issuer, such as management performance and reduced demand for the issuer’s goods or services. To the extent a significant portion of the Fund’s assets provides economic exposure to a limited number of issuers, the appreciation or depreciation of the Fund’s exposure to any one issuer may have a greater impact on the Fund’s net asset value than it would if the Fund’s assets provided exposure to a greater number of issuers. |
| 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.
|
| Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk: Liquidity risk exists when the markets for particular securities or types of securities or other investments are or become relatively illiquid, making it difficult or impossible for the Fund to dispose of the security or investment. Illiquidity may result from political, economic or issuer specific events; supply/demand imbalances; changes in a specific market’s size or structure; or overall market disruptions. Investments in securities or other assets with reduced liquidity or that become illiquid may involve greater risk than securities with more liquid markets. Market prices or quotations for illiquid securities may be volatile, and there may be large spreads between bid and ask prices. Reduced liquidity may have an adverse impact on market price of particular securities and may adversely affect the Fund’s ability to sell those securities when necessary to meet the Fund’s liquidity needs. To the extent that the Fund and its affiliates hold a significant portion of an issuer’s outstanding securities, the Fund may be subject to greater liquidity risk than if the issuer’s securities were more widely held.

| 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 and its investments. The Fund’s NAV could decline over short periods due to short-term market movements and over longer periods during market downturns. Trade policy, including the imposition of tariffs, may dampen consumer spending and result in decreased confidence in the 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 diseases, inflation and recessions, changes in interest or exchange rates, or other events could have a significant impact on the Fund and its investments and trading of its Shares. Market risk factors may result in increased volatility and/or decreased liquidity in the securities markets. |
| New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk: The Fund is a new fund, with limited or 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.
|
| Newly Listed Company Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Newly Listed Company Risk: Newly listed companies may include companies that recently offered new issues of equity securities through direct listings or IPOs, have a trading history on exchanges in other countries, or have been spun-off of a publicly-traded company, but have limited trading history on the exchange where the Fund has obtained investment exposure. There may be less information available about these companies and their operations, including with respect to performance. Newly listed securities issued in direct listings and IPOs have no trading history, and publicly available information about the companies’ operations may cover very limited periods. In addition, the prices of newly listed securities may be highly volatile or may decline shortly after listing on the exchange. Direct listing or IPO shares are subject to heightened market risk and liquidity risk, and may involve high transaction costs.
|
| 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, cyber security incidents, and technology or systems failures. 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. |
| Outbound Investment Restrictions Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Outbound Investment Restrictions Risk: In addition to economic sanctions and tariffs, the U.S. Department of the Treasury's Outbound Investment Security Program and related laws such as the COINS Act restrict or require notification (or will when they are fully implemented) of certain U.S. person investments in entities linked to the People's Republic of China, Hong Kong, Macau, Cuba, Iran, North Korea, Russia, and Venezuela under the regime of Nicolas Maduro (each, a "country of concern") that are engaged in specified activities involving semiconductors and microelectronics, quantum information technologies, certain artificial intelligence systems, high-performance computing and supercomputing and hypersonic systems. Some transactions, including certain transactions in publicly traded securities and cash settled derivatives, are excepted from these requirements, subject to conditions. While these restrictions are presently focused on a limited number of countries and industries, new regulations or laws may expand the restrictions or notifications, cover additional sectors, countries, or types of transactions, or could limit or eliminate exclusions from these provisions. In addition, the United States has imposed sanctions on certain Chinese companies, including those identified as part of the Chinese Military-Industrial Complex (“CMIC”). These sanctions generally prohibit U.S. persons from purchasing or selling publicly traded securities of designated CMIC entities. The CMIC list has evolved over time and may continue to expand, which could affect companies in technology, telecommunications, and defense-related sectors. Changes in these regulations, laws, and sanctions in the U.S. and elsewhere could affect the ability of the Fund to invest in certain companies or industries, adversely affect the Fund’s value or liquidity, or could require divestment of existing holdings and may require the Fund to notify the U.S. Treasury and/or take other steps. The scope and impact of these rules are evolving, and it is not possible to predict how they may develop or how they may affect the Fund. These and similar developments could negatively affect Fund performance and may increase diligence and reporting costs for the Fund.

| 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: Certain shareholders, including an Authorized Participant, the Adviser, an affiliate of the Adviser, or funds managed by the Adviser, may own a substantial amount of the Fund’s Shares. 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.

| Prospectus [Line Items] | |
| 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.

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.
|
| Swap Agreements Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Swap Agreements Risk: Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of a specified security). Swap agreements may be negotiated bilaterally and traded over-the-counter (“OTC”) between two parties or, in some instances, must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. Certain standardized swaps are subject to mandatory central clearing. Central clearing is intended to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. The Fund may be required to post margin or collateral with a clearinghouse or custodian. Operational failures and/or improper segregation of assets held by a clearinghouse or custodian may affect the Fund’s rights under a swap agreement and/or result in a loss of assets posted as margin or collateral. Swap agreements may involve greater risks than direct investment in securities. |
| 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. The Fund will seek to comply with the asset diversification test applicable to a RIC (the “Diversification Requirement”). The determination of the value and the identity of the issuer of derivatives, such as swap agreements, is often unclear for purposes of the Diversification Requirement. Although the Fund intends to carefully monitor its investments in derivatives to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service (“IRS”) will agree with the Fund’s determination of the issuer and valuation of such derivatives under the Diversification Requirement with respect to such derivatives. The Adviser’s efforts to satisfy the Fund’s Diversification Requirement may compromise its ability to implement the Fund’s investment strategy as effectively as it might otherwise have been able to in the absence of such a requirement.
|
| Trading Halt Risk Member | |
| Prospectus [Line Items] | |
| 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.
|
| Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Turnover Risk: The Fund may engage in frequent and active trading, which may significantly increase the Fund’s portfolio turnover rate. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. For example, a portfolio turnover rate of 300% is equivalent to the Fund buying and selling all of its securities three times during the course of a year. A high portfolio turnover rate would result in high brokerage costs for the Fund. A high portfolio turnover rate may result in higher taxes when Shares are held in a taxable account, including an increase in taxable capital gains distributions to Fund shareholders, and may lower the Fund's after-tax performance.
|
| Valuation Risk Member | |
| 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, 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.
|
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. |
| Risk Not Insured Depository Institution [Member] | |
| 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"), which means that the Fund may invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.
