| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as brokerage commissions, when it buys and sells securities (or “turns over” its portfolio). 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 total annual Fund operating expenses or in the Example, affect the Fund’s performance. Because the Fund has not commenced investment operations as of the date of this prospectus, it does not have portfolio turnover information to report. |

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”). In seeking to achieve its investment objective, the Fund utilizes an absolute return approach that is designed to provide exposure to a wide range of equity securities, fixed income securities, commodities and currencies of domestic and foreign issuers, with no prescribed asset allocation targets under normal circumstances. As such, exposures across asset classes may vary widely, and the Fund’s assets may exhibit an equity, fixed income, commodity or currency bias at any given time. The Fund operates in a manner that is commonly referred to as a “fund of funds” and obtains investment exposure to the asset classes described below primarily by investing in other ETFs. The Fund generally expects to hold approximately six to twenty underlying ETFs.
The Fund’s equity investments may include common stock, preferred stock, securities convertible into other equity securities, and real estate investment trusts (“REITs”). The Fund may invest in the equity securities of U.S. and foreign companies of various market capitalizations, including in emerging and developed markets.
The Fund’s fixed income securities may include securities issued or guaranteed by the U.S. Government and its agencies or instrumentalities, municipal securities, corporate debt securities, commercial paper, residential and commercial mortgage-backed securities, asset-backed securities (including collateralized loan obligations and collateralized mortgage obligations), inflation-linked securities (e.g., Treasury inflation- protected securities (“TIPS”)), convertible securities, and bank loans. The Fund’s fixed income holdings are diversified across a wide range of short- to long-term income-producing securities issued by U.S. and international developed and emerging markets issuers. With respect to credit quality, the Fund may invest in both investment-grade and high-yield (also known as “junk bonds”) fixed income instruments. Fixed income securities are considered investment grade if they are rated in one of the four highest rating categories by a nationally recognized statistical ratings organization (“NRSRO”), such as S&P Global Ratings (“S&P”) or Moody’s Investor Services, Inc. (“Moody’s”), or determined by the Adviser to be of comparable quality at the time of purchase.
The Fund’s commodity exposure may include various commodities, including metals, energy, oil or agricultural products. The Fund will gain exposure to these commodities principally through investments in futures contracts and swaps. The Fund’s currency exposure may include various non-U.S. currencies and the Fund will gain exposure to these currencies primarily through foreign currency futures contracts and swaps.
The Adviser makes investment decisions by seeking to identity and assemble a portfolio of ETFs that will achieve its desired asset allocation mix while also optimizing for positive risk-adjusted returns (i.e., alpha) relative to the general equity, fixed income, commodities and currency markets. To accomplish this, the Adviser’s investment team determines the Fund’s asset allocation mix and conducts ongoing research into the ever-growing universe of ETFs and their investment managers, populating a list of ETFs from which the Fund’s portfolio is constructed. The asset allocation mix for the Fund is determined through the use of a mean variance optimization process, which seeks to identify a combination of asset classes that is expected to maximize return for a given level of risk, by focusing primarily on expected returns, standard deviations (i.e., volatility as a measure of risk) and correlations of the different asset classes.
The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
strategy underlying the manager’s investment thesis along with organizational factors including the manager’s compensation structure, board makeup, conflicts of interest and whether the portfolio managers of the ETF in question invest alongside clients.
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.
The Adviser has engaged Exchange Traded Concepts, LLC to serve as trading sub-adviser (“Sub-Adviser”) for the Fund. The Sub-Adviser is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions or in connection with any rebalancing or reconstitution of the portfolio, pre- and post-trade compliance, and monitoring of Fund trading activity, subject to the oversight of the Adviser and the Board of Trustees. |

| Frontier Asset Absolute Return ETF | Equity Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Risk - Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Large Capitalization Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large Capitalization Company Risk - The large capitalization companies in which the Fund may invest may lag the performance of smaller capitalization companies because large capitalization companies may experience slower rates of growth than smaller capitalization companies and may not respond as quickly to market changes and opportunities. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Small- and Mid-Capitalization Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small- and Mid-Capitalization Company Risk - The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small- and mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Preferred Stock Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Preferred Stock Risk - Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Convertible Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Convertible Securities Risk - The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | REITs Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | REITs Risk - REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Investment in Other Investment Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment in Other Investment Companies Risk - Because the Fund invests in other investment companies, such as ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. The Fund does not intend to invest in other investment companies unless the Adviser believes that the potential benefits of the investment justify the payment of any additional fees or expenses. Federal securities laws impose limitations on the Fund’s ability to invest in other investment companies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | ETF Risks | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF Risks - The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk - Shares of the Fund may trade on the Exchange above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Cash Transactions Risk - Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk - Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Fixed-Income Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Fixed-Income Securities Risk - The prices of the Fund’s fixed-income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed-income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed-income markets. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Commodities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commodities Risk - Commodities include, among other things, energy products, agricultural products, metals and oil. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The prices of energy, metals, oil, and agriculture sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Currency Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Currency Risk - The Fund may have exposure to foreign currencies. Foreign currencies may decline in value relative to the U.S. dollar, resulting in the dollar value of an investment in the Fund being adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments or central banks, or by the imposition of currency controls or other political developments in the United States or abroad. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Derivatives Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk – An underlying ETF’s use of futures contracts and swaps is subject to market risk, leverage risk, correlation risk and liquidity risk. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Leverage risk is the risk that since derivatives may be purchased for a fraction of their value, a relatively small price movement in a derivative may result in an immediate and substantial loss or gain for the underlying ETF. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly or at all with the underlying asset, rate or index. Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time and the price that the underlying ETF would like. Swaps are also subject to credit risk and valuation risk. Credit risk is the risk that the counterparty to a derivative contract will default or otherwise become unable to honor a financial obligation. Valuation risk is the risk that a security may be difficult to value. Each of these risks could cause an underlying ETF in which the Fund invests to lose more than the principal amount invested in a derivative instrument, which in turn could cause losses for the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Interest Rate Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk - The risk that a change in interest rates will cause a fall in the value of fixed-income securities, including U.S. Government securities, in which the Fund invests. Generally the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | High Yield Bond Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | High Yield Bond Risk - High yield, or “junk,” bonds are debt securities rated below investment grade. High yield bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Non-U.S. Government Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Non-U.S. Government Securities Risk - Foreign sovereign debt securities are subject to the risks that: (i) the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or interest when it becomes due, due to factors such as debt service burden, political constraints, cash flow problems and other national economic factors; (ii) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling or additional lending to defaulting governments; and (iii) there is no bankruptcy proceeding by which defaulted sovereign debt may be collected in whole or in part. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Corporate Fixed Income Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Corporate Fixed Income Securities Risk - Corporate fixed-income securities are fixed-income securities issued by public and private businesses. Corporate fixed-income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers. Corporate fixed income securities are subject to the risk that the issuer may not be able to pay interest or, ultimately, to repay principal upon maturity. Interruptions or delays of these payments could adversely affect the market value of the security. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Commercial Paper Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commercial Paper Risk - Commercial paper is a short-term obligation with a maturity generally ranging from one to 270 days and is issued by U.S. or foreign companies or other entities in order to finance their current operations. Such investments are unsecured and usually discounted from their value at maturity. The value of commercial paper may be affected by changes in the credit rating or financial condition of the issuing entities and will tend to fall when interest rates rise and rise when interest rates fall. Asset-backed commercial paper may be issued by structured investment vehicles or other conduits that are organized to issue the commercial paper and to purchase trade receivables or other financial assets. The repayment of asset-backed commercial paper depends primarily on the cash collections received from such an issuer’s underlying asset portfolio and the issuer’s ability to issue new asset-backed commercial paper. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Credit Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Credit Risk - The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | U.S. Government Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | U.S. Government Securities Risk - Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Foreign Government Agencies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Government Agencies Risk - Bonds issued by government agencies, subdivisions or instrumentalities of foreign governments are generally backed only by the general creditworthiness and reputation of the entity issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to provide that support. A foreign government agency’s operations and financial condition are influenced by the foreign government’s economic and other policies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Municipal Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Municipal Securities Risk - Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer’s current or future ability to make principal or interest payments. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Residential Mortgage-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Residential Mortgage-Backed Securities Risk - Mortgage-backed securities are fixed income securities representing an interest in a pool of underlying mortgage loans. Mortgage-backed securities are sensitive to changes in interest rates, but may respond to these changes differently from other fixed income securities due to the possibility of prepayment of the underlying mortgage loans. As a result, it may not be possible to determine in advance the actual maturity date or average life of a mortgage-backed security. Rising interest rates tend to discourage re-financings, with the result that the average life and volatility of the security will increase, exacerbating its decrease in market price. When interest rates fall, however, mortgage-backed securities may not gain as much in market value because of the expectation of additional mortgage prepayments, which must be reinvested at lower interest rates. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Commercial Mortgage-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commercial Mortgage-Backed Securities Risk - Commercial mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Prepayment and Extension Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Prepayment and Extension Risk - When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Asset-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Asset-Backed Securities Risk - Asset-backed securities are securities backed by non-mortgage assets such as company receivables, truck and auto loans, leases and credit card receivables. Asset-backed securities may be issued as pass-through certificates, which represent undivided fractional ownership interests in the underlying pools of assets. Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Inflation Linked Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Inflation Linked Securities Risk - Inflation linked securities, including TIPS, are fixed income securities for which the principal and/or interest income paid is linked to inflation rates. The relationship between an inflation linked security and its associated inflation index affects both the sum the Fund is paid when the security matures and the amount of interest that the security pays the Fund. With inflation (a rise in the index), the principal of the security increases. With deflation (a drop in the index), the principal of the security decreases. Inflation protected securities pay interest at a fixed rate. Because the rate is applied to the adjusted principal, however, interest payments can vary in amount from one period to the next. If inflation occurs, the interest payment increases. In the event of deflation, the interest payment decreases. At the maturity of a security, the Fund receives the adjusted principal or the original principal, whichever is greater. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Absolute Return ETF | Foreign Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Company Risk - Investing in foreign companies poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |

| Risk [Text Block] | rr_RiskTextBlock | Emerging Markets Securities Risk - Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |

| Risk [Text Block] | rr_RiskTextBlock | Foreign Currency Risk - As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Bank Loans Risk - Investments in bank loans (through both assignments and participations) are generally subject to the same risks as investments in other types of debt instruments, including, in many cases, investments in high yield bonds. There may be limited public information available regarding bank loans and bank loans may be difficult to value. If the Fund holds a bank loan through another financial institution, or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. It is possible that collateral securing a loan, if any, may be insufficient or unavailable to the Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Bank loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. |

These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn. CLOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. |

| Risk [Text Block] | rr_RiskTextBlock | Collateralized Mortgage Obligations (“CMOs”) Risk - CMOs exhibit similar risks to those of mortgage-backed securities but also present certain special risks. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (“tranches”) with different priority rights to portions of the underlying mortgage payments. As market conditions change, however, particularly during periods of rapid or unanticipated changes in interest rates, the ability of a CMO tranche to provide the anticipated investment characteristics and performance may be significantly reduced. These changes may result in volatility in the market value, and in some instances reduced liquidity, of the CMO tranche. |

| Risk [Text Block] | rr_RiskTextBlock | Money Market Instruments Risk - The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded Fund (“ETF”). Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in investment-grade fixed income securities. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders. The Fund operates in a manner that is commonly referred to as a “fund of funds” and obtains investment exposure to the asset classes described below primarily by investing in other ETFs. The Fund generally expects to hold approximately six to twelve underlying ETFs.
For purposes of the Fund’s 80% investment policy, fixed income securities include securities issued or guaranteed by the U.S. Government, corporate debt securities, commercial paper, residential and commercial mortgage-backed securities, asset-backed securities, and inflation-linked securities (e.g., Treasury inflation-protected securities (“TIPS”)). The Adviser considers fixed income securities to be investment grade if they are rated in one of the four highest rating categories by a nationally recognized statistical ratings organization (“NRSRO”), such as S&P Global Ratings (“S&P”) or Moody’s Investor Services, Inc. (“Moody’s”), or determined by the Adviser to be of comparable quality at the time of purchase.
The Fund is managed to achieve broad exposure to the U.S. investment-grade fixed income securities market. The Fund does not target a specific weighted average maturity for its investments, either individually or in the aggregate. As a result, the Fund’s interest rate sensitivity may vary significantly over time.
The Adviser makes investment decisions by seeking to identity and assemble a portfolio of ETFs that will achieve its desired asset allocation mix while also optimizing for positive risk-adjusted returns (i.e., alpha) relative to the general investment-grade fixed income market. To accomplish this, the Adviser’s investment team determines the Fund’s asset allocation mix and conducts ongoing research into the ever-growing universe of ETFs and their investment managers, populating a list of ETFs from which the Fund’s portfolio is constructed. The asset allocation mix for the Fund is determined through the use of a mean variance optimization process, which seeks to identify a combination of asset classes that is expected to maximize return for a given level of risk, by focusing primarily on expected returns, standard deviations (i.e., volatility as a measure of risk) and correlations of the different asset classes.
The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
and whether the manager has a reasonable edge in exploiting them. Examples of market inefficiencies may include behavioral biases such as anchoring bias (relying too heavily on an initial piece of information when making decisions), confirmation bias (seeking out or giving more weight to information that supports original estimates) and overconfidence (displaying a hesitance to acknowledge potential errors in an initial analysis). In practice, these biases can lead to delayed or gradual revisions of earnings forecasts, even when significant changes in a company’s fundamentals or external environment may warrant more immediate adjustments. The Adviser believes that a manager who understands these dynamics and puts in place processes to combat these biases may be in a better position to adjust their portfolio to incorporate new information, compared to managers who under-react to new information due to these biases.
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.
The Adviser has engaged Exchange Traded Concepts, LLC to serve as trading sub-adviser (“Sub-Adviser”) for the Fund. The Sub-Adviser is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions or in connection with any rebalancing or reconstitution of the portfolio, pre- and post-trade compliance, and monitoring of Fund trading activity, subject to the oversight of the Adviser and the Board of Trustees. |

| Frontier Asset Core Bond ETF | Investment in Other Investment Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment in Other Investment Companies Risk - Because the Fund invests in other investment companies, such as ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. The Fund does not intend to invest in other investment companies unless the Adviser believes that the potential benefits of the investment justify the payment of any additional fees or expenses. Federal securities laws impose limitations on the Fund’s ability to invest in other investment companies. |

| Frontier Asset Core Bond ETF | ETF Risks | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF Risks - The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk - Shares of the Fund may trade on the Exchange above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Cash Transactions Risk - Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk - Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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. |

| Risk [Text Block] | rr_RiskTextBlock | Fixed-Income Securities Risk - The prices of the Fund’s fixed-income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed-income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed-income markets. |

Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. |

Corporate fixed-income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers. Corporate fixed income securities are subject to the risk that the issuer may not be able to pay interest or, ultimately, to repay principal upon maturity. Interruptions or delays of these payments could adversely affect the market value of the security. |

| Risk [Text Block] | rr_RiskTextBlock | Commercial Paper Risk - Commercial paper is a short-term obligation with a maturity generally ranging from one to 270 days and is issued by U.S. or foreign companies or other entities in order to finance their current operations. Such investments are unsecured and usually discounted from their value at maturity. The value of commercial paper may be affected by changes in the credit rating or financial condition of the issuing entities and will tend to fall when interest rates rise and rise when interest rates fall. Asset-backed commercial paper may be issued by structured investment vehicles or other conduits that are organized to issue the commercial paper and to purchase trade receivables or other financial assets. The repayment of asset-backed commercial paper depends primarily on the cash collections received from such an issuer’s underlying asset portfolio and the issuer’s ability to issue new asset-backed commercial paper. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Residential Mortgage-Backed Securities Risk - Mortgage-backed securities are fixed income securities representing an interest in a pool of underlying mortgage loans. Mortgage-backed securities are sensitive to changes in interest rates, but may respond to these changes differently from other fixed income securities due to the possibility of prepayment of the underlying mortgage loans. As a result, it may not be possible to determine in advance the actual maturity date or average life of a mortgage-backed security. Rising interest rates tend to discourage re-financings, with the result that the average life and volatility of the security will increase, exacerbating its decrease in market price. When interest rates fall, however, mortgage-backed securities may not gain as much in market value because of the expectation of additional mortgage prepayments, which must be reinvested at lower interest rates. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Core Bond ETF | Commercial Mortgage-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commercial Mortgage-Backed Securities Risk - Commercial mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Prepayment and Extension Risk - When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. |

| Risk [Text Block] | rr_RiskTextBlock | Asset-Backed Securities Risk - Asset-backed securities are securities backed by non-mortgage assets such as company receivables, truck and auto loans, leases and credit card receivables. Asset-backed securities may be issued as pass-through certificates, which represent undivided fractional ownership interests in the underlying pools of assets. Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets. |

| Risk [Text Block] | rr_RiskTextBlock | Investing in the United States Risk - The Fund focuses its investments in the United States.

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Inflation Protected Securities Risk - Inflation protected securities, including TIPS, are fixed income securities for which the principal and/or interest income paid is linked to inflation rates. The relationship between an inflation protected security and its associated inflation index affects both the sum the Fund is paid when the security matures and the amount of interest that the security pays the Fund. With inflation (a rise in the index), the principal of the security increases. With deflation (a drop in the index), the principal of the security decreases. Inflation protected securities pay interest at a fixed rate. Because the rate is applied to the adjusted principal, however, interest payments can vary in amount from one period to the next. If inflation occurs, the interest payment increases. In the event of deflation, the interest payment decreases. At the maturity of a security, the Fund receives the adjusted principal or the original principal, whichever is greater. |

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded Fund (“ETF”). Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders. The Fund operates in a manner that is commonly referred to as a “fund of funds” and obtains investment exposure to the asset classes described below primarily by investing in other ETFs. The Fund generally expects to hold approximately six to twelve underlying ETFs.
For purposes of the Fund’s 80% investment policy, fixed income securities include securities issued or guaranteed by U.S. and non-U.S. government issuers, corporate debt securities, municipal securities, commercial paper, residential and commercial mortgage-backed securities, asset-backed securities (including collateralized loan obligations and collateralized mortgage obligations), convertible securities, inflation-linked securities (e.g., Treasury inflation-protected securities (“TIPS”)) and bank loans. The Fund may invest in investment-grade and non-investment grade fixed income securities. The Adviser considers fixed income securities to be investment grade if they are rated in one of the four highest rating categories by a nationally recognized statistical ratings organization (“NRSRO”), such as S&P Global Ratings (“S&P”) or Moody’s Investor Services, Inc. (“Moody’s”), or determined by the Adviser to be of comparable quality at the time of purchase. The Adviser considers fixed income securities to be below investment grade (also known as “high yield” or “junk” bonds”) if they are rated below BBB- or Baa3 by Moody’s, S&P or Fitch, Inc. (“Fitch”), or if unrated, determined to be of comparable quality by the Adviser.
The Fund is managed to achieve broad exposure to the U.S. investment-grade and non-investment grade fixed income securities market. The Fund does not target a specific weighted average maturity for its investments, either individually or in the aggregate. As a result, the Fund’s interest rate sensitivity may vary significantly over time.
The Adviser makes investment decisions by seeking to identity and assemble a portfolio of ETFs that will achieve its desired asset allocation mix while also optimizing for positive risk-adjusted returns (i.e., alpha) relative to the general fixed income market. To accomplish this, the Adviser’s investment team determines the Fund’s asset allocation mix and conducts ongoing research into the ever-growing universe of ETFs and their investment managers, populating a list of ETFs from which the Fund’s portfolio is constructed. The asset allocation mix for the Fund is determined through the use of a mean variance optimization process, which seeks to identify a combination of asset classes that is expected to maximize return for a given level of risk, by focusing primarily on expected returns, standard deviations (i.e., volatility as a measure of risk) and correlations of the different asset classes.
The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
structure, board makeup, conflicts of interest and whether the portfolio managers of the ETF in question invest alongside clients.
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.
The Adviser has engaged Exchange Traded Concepts, LLC to serve as trading sub-adviser (“Sub-Adviser”) for the Fund. The Sub-Adviser is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions or in connection with any rebalancing or reconstitution of the portfolio, pre- and post-trade compliance, and monitoring of Fund trading activity, subject to the oversight of the Adviser and the Board of Trustees. |

| Frontier Asset Opportunistic Credit ETF | Convertible Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Convertible Securities Risk - The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Opportunistic Credit ETF | Investment in Other Investment Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment in Other Investment Companies Risk - Because the Fund invests in other investment companies, such as ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. The Fund does not intend to invest in other investment companies unless the Adviser believes that the potential benefits of the investment justify the payment of any additional fees or expenses. Federal securities laws impose limitations on the Fund’s ability to invest in other investment companies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Opportunistic Credit ETF | ETF Risks | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF Risks - The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk - Shares of the Fund may trade on the Exchange above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Cash Transactions Risk - Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk - Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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. |

| Frontier Asset Opportunistic Credit ETF | Fixed-Income Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Fixed-Income Securities Risk - The prices of the Fund’s fixed-income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed-income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed-income markets. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Opportunistic Credit ETF | Interest Rate Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk - The risk that a change in interest rates will cause a fall in the value of fixed-income securities, including U.S. Government securities, in which the Fund invests. Generally the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. |

| Frontier Asset Opportunistic Credit ETF | High Yield Bond Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | High Yield Bond Risk - High yield, or “junk,” bonds are debt securities rated below investment grade. High yield bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Non-U.S. Government Securities Risk - The risks that: (i) the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or interest when it becomes due, due to factors such as debt service burden, political constraints, cash flow problems and other national economic factors; (ii) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling or additional lending to defaulting governments; and (iii) there is no bankruptcy proceeding by which defaulted sovereign debt may be collected in whole or in part. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Corporate Fixed Income Securities Risk - Corporate fixed-income securities are fixed-income securities issued by public and private businesses. Corporate fixed-income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers. Corporate fixed income securities are subject to the risk that the issuer may not be able to pay interest or, ultimately, to repay principal upon maturity. Interruptions or delays of these payments could adversely affect the market value of the security. |

| Frontier Asset Opportunistic Credit ETF | Commercial Paper Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commercial Paper Risk - Commercial paper is a short-term obligation with a maturity generally ranging from one to 270 days and is issued by U.S. or foreign companies or other entities in order to finance their current operations. Such investments are unsecured and usually discounted from their value at maturity. The value of commercial paper may be affected by changes in the credit rating or financial condition of the issuing entities and will tend to fall when interest rates rise and rise when interest rates fall. Asset-backed commercial paper may be issued by structured investment vehicles or other conduits that are organized to issue the commercial paper and to purchase trade receivables or other financial assets. The repayment of asset-backed commercial paper depends primarily on the cash collections received from such an issuer’s underlying asset portfolio and the issuer’s ability to issue new asset-backed commercial paper. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | U.S. Government Securities Risk - Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources. |

| Frontier Asset Opportunistic Credit ETF | Foreign Government Agencies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Government Agencies Risk - Bonds issued by government agencies, subdivisions or instrumentalities of foreign governments are generally backed only by the general creditworthiness and reputation of the entity issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to provide that support. A foreign government agency’s operations and financial condition are influenced by the foreign government’s economic and other policies. |

| Frontier Asset Opportunistic Credit ETF | Municipal Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Municipal Securities Risk - Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer’s current or future ability to make principal or interest payments. |

| Frontier Asset Opportunistic Credit ETF | Residential Mortgage-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Residential Mortgage-Backed Securities Risk - Mortgage-backed securities are fixed income securities representing an interest in a pool of underlying mortgage loans. Mortgage-backed securities are sensitive to changes in interest rates, but may respond to these changes differently from other fixed income securities due to the possibility of prepayment of the underlying mortgage loans. As a result, it may not be possible to determine in advance the actual maturity date or average life of a mortgage-backed security. Rising interest rates tend to discourage re-financings, with the result that the average life and volatility of the security will increase, exacerbating its decrease in market price. When interest rates fall, however, mortgage-backed securities may not gain as much in market value because of the expectation of additional mortgage prepayments, which must be reinvested at lower interest rates. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Opportunistic Credit ETF | Commercial Mortgage-Backed Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Commercial Mortgage-Backed Securities Risk - Commercial mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities. |

| Frontier Asset Opportunistic Credit ETF | Prepayment and Extension Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Prepayment and Extension Risk - When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Asset-Backed Securities Risk - Asset-backed securities are securities backed by non-mortgage assets such as company receivables, truck and auto loans, leases and credit card receivables. Asset-backed securities may be issued as pass-through certificates, which represent undivided fractional ownership interests in the underlying pools of assets. Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Inflation Linked Securities Risk - Inflation linked securities, including TIPS, are fixed income securities for which the principal and/or interest income paid is linked to inflation rates. The relationship between an inflation linked security and its associated inflation index affects both the sum the Fund is paid when the security matures and the amount of interest that the security pays the Fund. With inflation (a rise in the index), the principal of the security increases. With deflation (a drop in the index), the principal of the security decreases. Inflation protected securities pay interest at a fixed rate. Because the rate is applied to the adjusted principal, however, interest payments can vary in amount from one period to the next.

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Bank Loans Risk - Investments in bank loans (through both assignments and participations) are generally subject to the same risks as investments in other types of debt instruments, including, in many cases, investments in high yield bonds. There may be limited public information available regarding bank loans and bank loans may be difficult to value. If the Fund holds a bank loan through another financial institution, or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. It is possible that collateral securing a loan, if any, may be insufficient or unavailable to the Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Bank loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Collateralized Loan Obligations (“CLOs”) Risk - Collateralized loan obligations are generally subject to credit, interest rate, prepayment and extension, valuation and liquidity risks, which are described elsewhere in this section. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn. CLOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. |

| Frontier Asset Opportunistic Credit ETF | Money Market Instruments Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Money Market Instruments Risk - The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. The regulations governing money market funds were recently amended in July, 2023, and their implementation and interpretation, as well as enforcement, may affect the manner of operation, performance and/or yield of money market funds. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk - Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |

| Risk [Text Block] | rr_RiskTextBlock | Investing in the United States Risk - The Fund focuses its investments in the United States. As a result, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within the United States, and may be subject to greater price volatility and risk of loss, than a fund holding more geographically diverse investments. |

| Risk [Text Block] | rr_RiskTextBlock | Mortgage-Backed Securities Risk - Mortgage-backed securities are affected by, among other things, interest rate changes and the possibility of prepayment of the underlying mortgage loans. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations. “To-be-announced” transactions (“TBA Transactions”) involve the additional risk that the value of the mortgage-backed securities to be purchased declines prior to settlement date or the counterparty does not deliver the securities as promised. |

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded Fund (“ETF”). Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of small-capitalization companies. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders. The Fund operates in a manner that is commonly referred to as a “fund of funds” and obtains investment exposure to the asset classes described below primarily by investing in other ETFs. The Fund generally expects to hold approximately six to twelve underlying ETFs. The Fund defines small-capitalization companies to include issuers with a market capitalization at the time of purchase within the capitalization range of companies in the Morningstar Developed Markets Small Cap Index. Given the Fund’s investment strategy, the Fund’s assets may exhibit either growth or value bias at any given time.
Under normal circumstances, the Fund invests in at least three countries, including the U.S., and invests at least 40% of its total assets in securities of non-U.S. companies, which may include emerging market countries. The Fund considers a company to be a non-U.S. company if: (i) at least 50% of the company’s assets are located outside of the U.S.; (ii) at least 50% of the company’s revenue or profits are generated outside of the U.S.; (iii) the company is organized or maintains its principal place of business outside of the U.S.; or (iv) the company’s securities are traded principally outside of the U.S.
The equity securities in which the Fund generally invests are common stocks. For purposes of the Fund’s 80% investment policy, however, equity securities also include preferred stocks and American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”)), which are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies. With respect to 20% of the Fund’s net assets, the Fund may also invest in the equity securities of mid-capitalization companies.
The Adviser makes investment decisions by seeking to identity and assemble a portfolio of ETFs that will achieve its desired asset allocation mix while also optimizing for positive risk-adjusted returns (i.e., alpha) relative to the global small-capitalization equity market. To accomplish this, the Adviser’s investment team determines the Fund’s asset allocation mix and conducts ongoing research into the ever-growing universe of ETFs and their investment managers, populating a list of ETFs from which the Fund’s portfolio is constructed. The asset allocation mix for the Fund is determined through the use of a mean variance optimization process, which seeks to identify a combination of asset classes that is expected to maximize return for a given level of risk, by focusing primarily on expected returns, standard deviations (i.e., volatility as a measure of risk) and correlations of the different asset classes.
The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
structure, board makeup, conflicts of interest and whether the portfolio managers of the ETF in question invest alongside clients.
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.
The Adviser has engaged Exchange Traded Concepts, LLC to serve as trading sub-adviser (“Sub-Adviser”) for the Fund. The Sub-Adviser is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions or in connection with any rebalancing or reconstitution of the portfolio, pre- and post-trade compliance, and monitoring of Fund trading activity, subject to the oversight of the Adviser and the Board of Trustees. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Risk - Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Preferred Stock Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Preferred Stock Risk - Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Investment in Other Investment Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment in Other Investment Companies Risk - Because the Fund invests in other investment companies, such as ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. The Fund does not intend to invest in other investment companies unless the Adviser believes that the potential benefits of the investment justify the payment of any additional fees or expenses. Federal securities laws impose limitations on the Fund’s ability to invest in other investment companies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | ETF Risks | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF Risks - The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk - Shares of the Fund may trade on the Exchange above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Cash Transactions Risk - Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk - Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Foreign Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Company Risk - Investing in foreign companies poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Emerging Markets Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging Markets Securities Risk - Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Foreign Currency Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Currency Risk - As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Liquidity Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk - Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Valuation Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk - The risk that a security may be difficult to value. The Fund may value certain securities at a price higher or lower than the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Active Management Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active Management Risk - The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to its benchmark index or other funds with similar objectives and investment strategies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | New Adviser Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New Adviser Risk - The Adviser has not previously served as an adviser to a registered investment company. As a result, investors do not have a track record of managing an ETF from which to judge the Adviser, and the Adviser may not achieve the intended result in managing the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | New Fund Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New Fund Risk - Because the Fund is new, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation. |

| Frontier Asset Global Small Cap Equity ETF | Small-Capitalization Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small-Capitalization Companies Risk - The risk that, compared to mid- and large- capitalization companies, small-capitalization companies in which the Fund may invest may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Mid-Capitalization Companies Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Mid-Capitalization Companies Risk - The risk that mid-capitalization companies in which the Fund may invest may have greater price volatility, lower trading volume and be more vulnerable to adverse business or economic events than larger, more established companies. In addition, mid-capitalization companies may have narrow product lines, smaller shares of their product or service markets and fewer financial resources than large capitalization companies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Growth Investment Style Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Growth Investment Style Risk - An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Global Small Cap Equity ETF | Value Investment Style Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Value Investment Style Risk - An investment in value stocks presents the risk that the stocks may never reach what the Adviser or a sub-adviser believes are their full market values, either because the market fails to recognize what the Adviser or a sub-adviser considers to be the companies’ true business values or because the Adviser or sub-adviser misjudged those values. In addition, value stocks may fall out of favor with investors and underperform growth stocks during given periods. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Depositary Receipts Risk - Depositary receipts, such as ADRs, GDRs and EDRs, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. |

The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.
The Adviser has engaged Exchange Traded Concepts, LLC to serve as trading sub-adviser (“Sub-Adviser”) for the Fund. The Sub-Adviser is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions or in connection with any rebalancing or reconstitution of the portfolio, pre- and post-trade compliance, and monitoring of Fund trading activity, subject to the oversight of the Adviser and the Board of Trustees. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Risk - Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Preferred Stock Risk - Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |

| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment in Other Investment Companies Risk - Because the Fund invests in other investment companies, such as ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. The Fund does not intend to invest in other investment companies unless the Adviser believes that the potential benefits of the investment justify the payment of any additional fees or expenses. Federal securities laws impose limitations on the Fund’s ability to invest in other investment companies. |

| Frontier Asset Total International Equity ETF | ETF Risks | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF Risks - The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk - Shares of the Fund may trade on the Exchange above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Cash Transactions Risk - Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk - Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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. |

| Frontier Asset Total International Equity ETF | Foreign Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Company Risk - Investing in foreign companies poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Emerging Markets Securities Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging Markets Securities Risk - Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |

| Frontier Asset Total International Equity ETF | Foreign Currency Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Currency Risk - As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Liquidity Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk - Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Valuation Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk - The risk that a security may be difficult to value. The Fund may value certain securities at a price higher or lower than the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Active Management Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active Management Risk - The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to its benchmark index or other funds with similar objectives and investment strategies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | New Adviser Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New Adviser Risk - The Adviser has not previously served as an adviser to a registered investment company. As a result, investors do not have a track record of managing an ETF from which to judge the Adviser, and the Adviser may not achieve the intended result in managing the Fund. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | New Fund Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New Fund Risk - Because the Fund is new, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation. |

| Frontier Asset Total International Equity ETF | Growth Investment Style Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Growth Investment Style Risk - An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Value Investment Style Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Value Investment Style Risk - An investment in value stocks presents the risk that the stocks may never reach what the Adviser or a sub-adviser believes are their full market values, either because the market fails to recognize what the Adviser or a sub-adviser considers to be the companies’ true business values or because the Adviser or sub-adviser misjudged those values. In addition, value stocks may fall out of favor with investors and underperform growth stocks during given periods. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Depositary Receipts Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Depositary Receipts Risk - Depositary receipts, such as ADRs, GDRs and EDRs, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. |

| Frontier Asset Total International Equity ETF | Large Capitalization Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large Capitalization Risk - If valuations of large capitalization companies appear to be greatly out of proportion to the valuations of small or medium capitalization companies, investors may migrate to the stocks of small and medium-sized companies. The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
||||||||||||||||||||||||||||||||||||
| Frontier Asset Total International Equity ETF | Mid-Capitalization Company Risk | ||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Mid-Capitalization Company Risk - The risk that mid-capitalization companies in which the Fund may invest may have greater price volatility, lower trading volume and be more vulnerable to adverse business or economic events than larger, more established companies. In addition, mid-capitalization companies may have narrow product lines, smaller shares of their product or service markets and fewer financial resources than large capitalization companies. |

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 total annual Fund operating expenses or in the Example, affect the Fund’s performance.

The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels.

||||||||||||||||||||||||||||||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded Fund (“ETF”). Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of large-capitalization U.S. companies. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders. Given the Fund’s investment strategy, the Fund’s assets may exhibit either growth or value bias at any given time. The Fund operates in a manner that is commonly referred to as a “fund of funds” and obtains investment exposure to the asset classes described below primarily by investing in other ETFs. The Fund generally expects to hold approximately six to twelve underlying ETFs.
The Fund considers a company to be a U.S. company if (i) at least 50% of the company’s assets are located in the U.S.; (ii) at least 50% of the company’s revenue or profits are generated in the U.S.; (iii) the company is organized or maintains its principal place of business in the U.S.; or (iv) the company’s securities are traded principally in the U.S. The Fund defines large-capitalization companies as issuers with a market capitalization within the range of companies in the S&P 500 Index at the time of purchase.
The equity securities in which the Fund generally invests are common stocks. For purposes of the Fund’s 80% investment policy, however, equity securities also include real estate investment trusts (“REITs”). With respect to 20% of the Fund’s net assets, the Fund may also invest in equity securities of mid-capitalization companies and equity securities of foreign companies in developed markets.
The Adviser makes investment decisions by seeking to identity and assemble a portfolio of ETFs that will achieve its desired asset allocation mix while also optimizing for positive risk-adjusted returns (i.e., alpha) relative to the general U.S. large-capitalization equity market. To accomplish this, the Adviser’s investment team determines the Fund’s asset allocation mix and conducts ongoing research into the ever-growing universe of ETFs and their investment managers, populating a list of ETFs from which the Fund’s portfolio is constructed. The asset allocation mix for the Fund is determined through the use of a mean variance optimization process, which seeks to identify a combination of asset classes that is expected to maximize return for a given level of risk, by focusing primarily on expected returns, standard deviations (i.e., volatility as a measure of risk) and correlations of the different asset classes.
The Adviser’s analysis and due diligence process for selecting prospective ETFs includes the following:
and whether the manager has a reasonable edge in exploiting them. Examples of market inefficiencies may include behavioral biases such as anchoring bias (relying too heavily on an initial piece of information when making decisions), confirmation bias (seeking out or giving more weight to information that supports original estimates) and overconfidence (displaying a hesitance to acknowledge potential errors in an initial analysis). In practice, these biases can lead to delayed or gradual revisions of earnings forecasts, even when significant changes in a company’s fundamentals or external environment may warrant more immediate adjustments. The Adviser believes that a manager who understands these dynamics and puts in place processes to combat these biases may be in a better position to adjust their portfolio to incorporate new information, compared to managers who under-react to new information due to these biases.
In conducting the qualitative and manager edge analysis described above, the Adviser relies on, among other publicly available sources of information, due diligence materials provided by managers as well as interviews conducted with such managers to discuss investment philosophy, processes, personnel and performance.
Following this process, the Adviser will select ETFs on the basis of their ability to provide low-cost asset class exposure, as compared to other actively managed ETFs, and/or the ability to add value on either an absolute or risk-adjusted basis, while also taking into account the following factors to form its views on which ETFs to select for the Fund’s portfolio: market conditions, valuation metrics, risk profiles, and expected growth potential. The Adviser will sell ETFs for a variety of reasons, including the need to alter asset allocation exposures, to add ETFs that the Adviser believes are better positioned to add value as compared to existing holdings, and to remove ETFs that no longer meet the investment criteria for the Fund.

REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses.

Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |

| Risk [Text Block] | rr_RiskTextBlock | New Fund Risk - Because the Fund is new, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation. |

| Risk [Text Block] | rr_RiskTextBlock | Growth Investment Style Risk - An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty.

| Risk [Text Block] | rr_RiskTextBlock | Value Investment Style Risk - An investment in value stocks presents the risk that the stocks may never reach what the Adviser or a sub-adviser believes are their full market values, either because the market fails to recognize what the Adviser or a sub-adviser considers to be the companies’ true business values or because the Adviser or sub-adviser misjudged those values. In addition, value stocks may fall out of favor with investors and underperform growth stocks during given periods. |
