A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal period October 22, 2014 (commencement of operations) through September 30, 2015, the Fund’s portfolio turnover rate was 69% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund seeks to achieve its investment objective by investing primarily in U.S. equity securities that Empowered Funds, LLC (the “Adviser”) believes, based on quantitative analysis, are undervalued at the time of purchase and have the potential for capital appreciation. A security is considered to be undervalued when it trades at a price below the price at which the Adviser believes it would trade if the market reflected all factors relating to the issuer’s worth. In choosing investments that are undervalued, the Adviser focuses on companies that it believes show indications of quality and financial strength but have security prices that are low relative to current operating earnings and/or are currently viewed unfavorably by equity research analysts. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of U.S. companies. The Fund will invest primarily in the exchange-listed common stock of U.S. companies. The Fund may invest in securities of companies in any industry and of any market capitalization. Although the Fund generally expects to invest in companies with larger market capitalizations, the Fund may invest in small- and mid-capitalization companies. The Fund is an actively managed ETF and thus does not seek to replicate the performance of a specific index. Rather, the Adviser has discretion on a daily basis to execute strategic decisions within the Fund’s portfolio in accordance with the Fund’s investment objective. The Adviser utilizes a quantitative model to identify which securities the Fund might purchase and sell as well as opportune times for purchases and sales. While the Fund will invest in approximately 50 U.S. equity securities as determined by its quantitative value factors, the quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund and the number of companies that satisfy the Adviser’s quantitative measurements at any one time. The Fund’s portfolio will be rebalanced to the Adviser’s internal target allocations, developed pursuant to the Adviser’s strategy described above, at least semi-annually. The Fund is a non-diversified fund and therefore may invest a greater portion of its assets in the securities of one or more issuers than a diversified fund.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective. An investor may lose money by investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will produce the intended results and no guarantee that the Fund will achieve its investment objective. As a result, the Fund could underperform compared to other funds with similar investment objectives. Value Style Investing Risk. A value stock may not increase in price as anticipated by the Adviser if other investors fail to recognize the company’s value and bid up the price, the markets favor faster-growing companies or the factors that the Adviser believes will increase the price of the security do not occur. Cyclical stocks in which the Fund may invest tend to lose value more quickly in periods of anticipated economic downturns than non-cyclical stocks. Companies that may be considered out of favor, particularly companies emerging from bankruptcy, may tend to lose value more quickly in periods of anticipated economic downturns, may have difficulty retaining customers and suppliers and, during economic downturns, may have difficulty paying their debt obligations or finding additional financing. Quantitative Security Selection Risk. Data for some companies may be less available and/or less current than data for companies in other markets. The Adviser uses a quantitative model to generate investment decisions and its processes and stock selection could be adversely affected if it relies on erroneous or outdated data. In addition, securities selected using the quantitative model could perform differently from the financial markets as a whole as a result of the characteristics used in the analysis, the weight placed on each characteristic and changes in the characteristic’s historical trends. Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. The values of equity securities could decline generally or could underperform other investments. In addition, securities may decline in value due to factors affecting a specific issuer, market or securities markets generally. Investment Risk. When you sell your Shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund. Premium-Discount Risk. The Shares may trade above or below their net asset value (“NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on BATS Exchange, Inc. (“Exchange”) or other securities exchanges. The trading price of Shares may deviate significantly from NAV during periods of market volatility or limited trading activity in Shares. Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Trading Risk. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Non-Diversification Risk. Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund’s Shares and greater risk of loss. Portfolio Turnover Risk. The Fund’s investment strategy may from time to time result in higher turnover rates. This may increase the Fund’s brokerage commission costs, which could negatively impact the performance of the Fund. Rapid portfolio turnover also exposes shareholders to a higher current realization of short-term capital gains, distributions of which would generally be taxed to you as ordinary income and thus cause you to pay higher taxes.
