Equity Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

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

 
Artificial Intelligence Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Artificial Intelligence Company Risk. Companies involved in, or exposed to, artificial intelligence related businesses may have limited product lines, markets, financial resources or personnel. These companies face intense competition and potentially rapid product obsolescence, and many depend significantly on retaining and growing the consumer base of their respective products and services. Many of these companies are also reliant on the end user demand of products and services in various industries that may in part utilize robotics and artificial intelligence.

 
Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Technology Sector Risk. The Fund will invest substantially in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

 
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers 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. Investments in foreign companies securities, including investments via depositary receipts, are subject to special risks, including the following:

 
Currency Exchange Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ●

Currency Exchange Rate Risk. The Fund’s assets may include exposure to investments denominated in non-U.S. currencies or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investments and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

 
Depositary Receipt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ●

Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.
Developed Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Developed Markets Risk. Developed market countries generally tend to rely on the services sectors (e.g., the financial services sector) as the primary source of economic growth and may be susceptible to the risks of individual service sectors. Many developed market countries have heavy indebtedness, which may lead downward pressure on the economies of these countries. As a result, it is possible that interest rates on debt of certain developed countries may rise to levels that make it difficult for such countries to service high debt levels without significant help from other countries or from a central bank. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries.

 
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Emerging Markets Risk. The Fund may invest in indirectly, via ADRs, in securities issued by companies domiciled or headquartered in emerging market nations. Investments in securities traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, currency, or regulatory conditions not associated with investments in U.S. securities and investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund Shares and cause the Fund to decline in value.

 
IPO Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

IPO Risk. The Fund may invest in securities offered in an IPO or in companies that have recently completed an IPO. The market value of IPO shares can have significant volatility due to factors such as the absence of a prior public market, unseasoned trading, a small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs, and the Fund may lose money on an investment in such securities.

Market Capitalization Risk.

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

 
Mid-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ○ Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.

 
Small-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ○ Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

 
Micro-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ○ Micro-Capitalization Investing. Micro-capitalization companies often have limited product lines, narrower markets for their goods and/or services and more limited managerial and financial resources than larger, more established companies, including companies which are considered small- or mid-capitalization. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund’s portfolio.

 
Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund will be concentrated in securities of issuers having their principal business activities in the technology group of industries. To the extent that the Fund concentrates in a group of industries, it will be subject to the risk that economic, political, or other conditions that have a negative effect on that group of industries will negatively impact them to a greater extent than if its assets were invested in a wider variety of industries.

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. Any such decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the Fund’s portfolio securities and the Fund’s market price. This reduced effectiveness could result in Fund shares trading at a premium or discount to its NAV and also greater than normal intraday bid-ask spreads.

 
Costs of Buying or Selling Shares [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ○

Costs of Buying or Selling Shares. Buying or selling Shares involves certain costs, including brokerage commissions, other charges imposed by brokers, and bid-ask spreads. The bid-ask spread represents the difference between the price at which an investor is willing to buy Shares and the price at which an investor is willing to sell Shares. The spread varies over time based on the Shares’ trading volume and market liquidity. The spread is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Due to the costs of buying or selling Shares, frequent trading of Shares may reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

 
Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ○

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

 
Trading [Member]

  ○ Trading. Although Shares are listed for trading on a national securities exchange, such as NYSE Arca, 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 portfolio holdings, which can be significantly less liquid than 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.

 
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Sub-Adviser’s success or failure to implement investment strategies for the Fund.

 
Models and Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Models and Data Risk. The Sub-Adviser’s evaluation of potential Fund portfolio holdings is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Fund’s portfolio that would have been excluded or included had the Models and Data been correct and complete.

 
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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] As with any investment, there is a risk that you could lose all or a portion of your investment 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.
