| Efficient Market Portfolio Plus ETF | Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. When you sell your Shares, they could be worth less than what you paid for them. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular asset classes or industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security. Geopolitical and other risks, including war, terrorism, trade disputes, political or economic dysfunction within some nations, public health crises, and environmental disasters such as earthquakes, fire, and floods, may add to instability in world economies and volatility in markets generally. Changes in trade policies and international trade agreements could affect the economies of many countries in unpredictable ways. The value of a security may also decline due to factors that affect a particular industry or group of industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected. Therefore, you may lose money by investing in the Fund.

| Efficient Market Portfolio Plus ETF | Momentum Style Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Momentum Style Risk. Investing in or having exposure to securities with the highest relative momentum entails investing in securities that have had above-average recent returns. These securities may be more volatile than a broad cross- section of securities. Returns on securities that have previously exhibited momentum may be less than returns on other styles of investing or the overall stock market. Momentum can turn quickly and cause significant variation from other types of investments, and stocks that previously exhibited high momentum may not experience continued highest relative momentum. In addition, there may be periods when the momentum style is out of favor, and during which the investment performance of the Fund using a momentum strategy may suffer.
|
| Efficient Market Portfolio Plus ETF | Equity Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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. |
| Efficient Market Portfolio Plus ETF | Short Sale Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Short Sale Risk. Short selling is generally considered speculative, has the potential for unlimited loss and may involve leverage, which can magnify the Fund’s exposure to assets that decline in value and increase the volatility of the Fund’s net asset value. If the price of a security which the Fund has sold short increases between the time of the short sale and when the position is closed out, the Fund will incur a loss equal to the increase in price from the time of the short sale plus any related interest payments, dividends, transaction or other costs. There can be no assurance that the Fund will be able to close out a short position at any particular time or at an acceptable price. Purchasing a security to cover a short position can itself cause the price of the security to rise, potentially exacerbating a loss or reducing a gain. In addition, the Fund is subject to the risk that the lender of a security will terminate the loan at a time when the Fund is unable to borrow the same instrument from another lender. A Fund that uses short sales is subject to the risk that its prime broker will be unwilling or unable to perform its contractual obligations. Regulatory restrictions limit the extent to which the Fund may engage in short sales.
|
| Efficient Market Portfolio Plus ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in or exposures to foreign securities are subject to special risks, including risks associated with foreign securities generally. Those special risks may arise due to differences in information available about issuers of securities and investor protection standards applicable in other jurisdictions; capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; currency risks; political, diplomatic and economic risks; regulatory risks; and foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions.
|
| Efficient Market Portfolio Plus ETF | Government Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Government Securities Risk. The Fund invests in U.S. Treasury obligations and securities issued or guaranteed by the U.S. Treasury. U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund.
|
| Efficient Market Portfolio Plus ETF | Risk Of Investing In Other ETFs Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in Other ETFs. Because the Fund may invest in other ETFs, the Fund’s investment performance is impacted by the investment performance of the selected underlying ETFs. An investment in the Fund is subject to the risks associated with the ETFs that then-currently comprise the Fund’s portfolio. At times, certain of the segments of the market represented by the Fund’s underlying ETFs may be out of favor and underperform other segments. The Fund will indirectly pay a proportional share of the expenses of the underlying ETFs in which it invests (including operating expenses and management fees), which are identified in the fee table above as “Acquired Fund Fees and Expenses.”
|
| Efficient Market Portfolio Plus ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. •Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“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. •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 NYSE Arca, Inc. (the “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. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price of the Shares. •Cost of 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. •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. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of its underlying portfolio holdings, which can be less liquid than Shares, potentially causing the market price of Shares to deviate from its NAV. The spread varies over time for Shares of the Fund based on the Fund’s trading volume and market liquidity and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size).

|
| Efficient Market Portfolio Plus ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Fund may invest a significant portion of its assets in the following sectors and, therefore, the performance of the Fund could be negatively impacted by events affecting each of these sectors. |
| Efficient Market Portfolio Plus ETF | 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 Adviser’s, Sub-Adviser’s, or portfolio managers’ success or failure to implement investment strategies for the Fund. The success of the Fund’s investment program depends largely on the investment techniques and risk analyses applied by the Adviser, Sub-Adviser, and the portfolio managers and the skill of the Adviser, Sub-Adviser, and/or portfolio managers in evaluating, selecting, and monitoring the Fund’s assets. The Fund could experience losses (realized and unrealized) if the judgment of the Adviser, Sub-Adviser, or portfolio managers about markets or sectors or the attractiveness of particular investments made for the Fund’s portfolio prove to be incorrect. It is possible the investment techniques and risk analyses employed on behalf of the Fund will not produce the desired results. |
| Efficient Market Portfolio Plus ETF | Monthly Reallocation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Monthly Reallocation Risk. Because the Sub-Adviser will generally reallocate the Fund’s portfolio on a monthly basis, (i) the Fund’s market exposure may be affected by significant market movements promptly following the monthly rebalancing that are not predictive of the market’s performance for the subsequent period and (ii) changes to the Fund’s market exposure may lag a significant change in the market’s direction (up or down) by as long as a month if such changes first take effect promptly following the rebalance. Such lags between market performance and changes to the Fund’s exposure may result in significant underperformance relative to the broader equity market.
|
| Efficient Market Portfolio Plus ETF | High Portfolio Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund’s investment strategy may 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.
|
| Efficient Market Portfolio Plus ETF | Inverse, And Inverse Leveraged ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inverse, and Inverse Leveraged ETF Risk. Inverse and inverse leveraged ETFs expose the Fund to all of the risks that traditional ETFs present. Inverse ETFs seek to provide investment results that match a negative (i.e., the opposite) of the performance of an underlying asset class. Leveraged inverse ETFs seek to provide investment results that match a negative multiple of the performance of an underlying asset class. All those types of ETFs rely to some degree, often extensively, on derivatives to achieve their objectives and, thus, the Fund is indirectly exposed to derivatives risk through its investments in these ETFs. Further, investments in inverse, or inverse leveraged ETFs are subject to the risk that the performance of the ETF will not correlate with the underlying asset class as intended. Inverse and inverse leveraged ETFs often “reset” daily, meaning that they are designed to achieve their stated objectives on a daily basis. Due to the effect of compounding, their performance over longer periods of time can differ significantly from the performance (or inverse of the performance) of their underlying asset class during the same period of time. This effect can be magnified in volatile markets. Consequently, these investment vehicles may be extremely volatile and can potentially expose the Fund to complete loss of its investment.
|
| Efficient Market Portfolio Plus ETF | Large Cap Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Cap Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion. |
| Efficient Market Portfolio Plus ETF | Small- And Mid-Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small- and Mid-Capitalization Companies 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.
|
| Efficient Market Portfolio Plus ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investor may lose money by investing in the Fund. |
| Efficient Market Portfolio Plus ETF | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. |
| Efficient Market Portfolio Plus ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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 Shares and greater risk of loss. |
| Efficient Market Portfolio Long ETF | Investment Risk Member | |
