Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as 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 at the shareholder level. These costs, which are not reflected in annual fund operating expenses or in the example above, affect the Fund’s performance. During the most recent fiscal year ended November 30, 2018, the Fund’s portfolio turnover rate was 16% of its average portfolio value.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is an exchange-traded fund (“ETF”) and employs a “passive management” – or indexing – investment approach designed to track the performance of the Underlying Index. The Underlying Index is a proprietary rules-based, capitalization weighted, float adjusted index designed to track the overall performance of equity securities of North American Pipeline Companies. The Fund will normally invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the types of securities suggested by its name (i.e., North American Pipeline Companies). A pipeline company is defined as a company that either 1) has been assigned a standard industrial classification (“SIC”) system code that indicates the company operates in the energy pipeline industry or 2) has at least 50% of its assets, cash flow or revenue associated with the operation or ownership of energy pipelines. Pipeline companies engage in the business of transporting natural gas, crude oil and refined products, storing, gathering and processing such gas, oil and products and local gas distribution.

To be included in the Underlying Index, a company must be a pipeline company that is organized and has its principal place of business in the United States or Canada (such pipeline companies are collectively referred to in this Prospectus as “North American Pipeline Companies”) and is listed on the New York Stock Exchange, NASDAQ, NYSE MKT or Toronto Stock Exchange. Eligible constituents must also have a total market capitalization of at least $200 million USD at the time of inclusion in the Underlying Index. In order to remain in the Underlying Index, a company must maintain an average equity market capitalization of at least $175 million USD for a minimum of 20 trading days prior to the rebalance reference date of the Underlying Index.

Underlying Index constituens may include the following equity securities of North American pipeline companies: 1) common stock; 2) interests in master limited partnerships (“MLPs”); 3) interests in Pipeline Companies structured as limited liability companies (“LLCs”); and 4) equity securities of MLP affiliates, including common shares of corporations that own, directly or indirectly, MLP general partner interests (collectively referred to herein as “MLP Affiliates”). MLP interests included in the Underlying Index must pay a distribution greater than or equal to their minimum quarterly distribution (“MQD”) at the time of inclusion in the Underlying Index. No more than 20% of the Underlying Index may consist of MLPs and no constituent can exceed 7.5% of the Underlying Index. Additionally, affiliated MLP families (e.g., related MLPs and/or MLP Affiliates) in aggregate may not comprise more than 15% of the Underlying Index at the rebalance reference date.

In seeking to achieve its objective as an index fund, the Fund will normally invest at least 80% of its total assets in securities that comprise the Underlying Index (or depository receipts based on such securities). Under normal conditions, the Fund generally will invest in all of the securities that comprise the Underlying Index in proportion to their weightings in the Underlying Index; however, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Underlying Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Underlying Index or utilize various combinations of other available investment techniques in seeking performance that corresponds to the performance of the Underlying Index. The Fund may invest up to 20% of its assets in certain index futures, options, options on index futures, swap contracts or other derivatives related to the Underlying Index and its components, cash and cash equivalents, other investment companies, as well as in securities and other instruments not included in the Underlying Index but which the Tortoise Index Solutions, LLC (the “Adviser”) believes will help the Fund track the Underlying Index.

As of the March 15, 2019 rebalance, the Underlying Index was comprised of 39 constituents. No constituents will be added to the Underlying Index between rebalance dates, which take place on a quarterly basis in March, June, September and December. Constituents are reviewed annually, at the December rebalance, to determine that they continue to meet the definition of Pipeline Company under the Underlying Index methodology. Constituents in the Underlying Index may be deleted from the Underlying Index due to corporate events such as mergers, acquisitions, bankruptcies, takeovers, or delistings. Standard rebalances take place on a quarterly basis. Special rebalances are triggered by corporate actions and will be implemented as practically as possible on a case-by-case basis. Underlying Index constituent changes and updates, as well as any changes to the methodology, will be posted to www.tortoiseadvisors.com. The Underlying Index was established by an affiliate of the Adviser and is owned and administered by the Adviser. The Adviser (also referred to herein as the “Index Provider”) provides the Underlying Index for use by the Fund at no cost to the Fund.

The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index concentrates in an industry or group of industries. The Underlying Index and the Fund will be concentrated in the energy pipeline industry.

The Fund has elected to be, and intends to qualify each year for treatment as a regulated investment company (“RIC”) under subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). As part of qualifying as a RIC under the Code, the Fund may not invest more than 25% of its total assets in the securities of MLPs and other entities treated as qualified publicly traded partnerships. If for any taxable year the Fund fails to qualify as a RIC, its taxable income will be subject to federal income tax at regular corporate rates and income available for distribution to shareholders will be reduced. Under certain circumstances, the Fund could cure a failure to qualify as a RIC, but in order to do so, the Fund could incur significant Fund-level taxes and could be forced to dispose of certain assets. Given the Fund’s contemplated investments in MLPs, qualifying as a RIC presents unusual challenges and may limit its investment opportunities.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all funds, a shareholder of the Fund is subject to the risk that his or her investment could lose money. The principal risks affecting shareholders’ investments in the Fund are set forth below. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any government agency.

General Market Risk. The Fund is subject to the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.

Concentration Risk. Because the Fund’s assets will be concentrated in the energy pipeline industry, the Fund is subject to loss due to adverse occurrences that may affect that industry. The Fund’s focus in this industry presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if a small number of its investments perform poorly.

Energy Pipeline Industry Risk. Companies in the energy pipeline industry are subject to many risks that can negatively impact the revenues and viability of companies in this industry, including but not limited to risks associated with companies owning and/or operating pipelines, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks.

Equity Securities Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of pipeline companies in particular, or a particular company.

MLP Risk. MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.

The Fund’s investment strategies depend in part on MLPs generally being treated as partnerships for U.S. federal income tax purposes. If any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction in the value of your investment in the Fund and lower distributions.

The Fund expects to receive cash distributions each year from certain MLPs that exceed the net taxable income allocated to the Fund from such MLPs for such year, and, as a result, the Fund may recognize larger taxable gains (or smaller losses) with respect to such MLPs when it disposes of its interests in such MLPs. If you hold shares in the Fund when such gains or losses are recognized, you may be required to pay tax on one or more Fund distributions, potentially at ordinary income tax rates, even though you may not have economically benefitted from the associated MLP cash distributions.

MLP Affiliate Risk. The performance of securities issued by MLP Affiliates, including common shares of corporations that own general partner interests, primarily depends on the performance of an MLP. The risks and uncertainties that affect the MLP, its operational results, financial condition, cash flows and distributions also affect the value of securities held by that MLP’s affiliate.

Non-U.S. Securities Risk. Investments in securities of non-U.S. issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.

Canadian Securities Risk. The Canadian economy may be significantly affected by the U.S. economy because the U.S. is Canada’s largest trading partner and foreign investor. Canada’s largest exports are its natural resources, so the Canadian economy is dependent on the demand for, and supply and price of, natural resources, and any market developments that reduce the price of such goods could disproportionately affect the Canadian economy.

Large-Cap, Mid-Cap and Small-Cap Companies Risk. The Fund’s investment in companies with large market capitalizations is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Securities of mid-cap and small-cap companies may be more volatile and less liquid than the securities of large-cap companies.

RIC Compliance Risk. The Fund has elected to be, and intends to qualify each year for treatment as, a “regulated investment company” (a “RIC”) under the Code. Given the Fund’s contemplated investments in MLPs, qualifying as a RIC presents unusual challenges and may limit its investment opportunities. If for any taxable year the Fund fails to qualify as a RIC, its taxable income will be subject to federal income tax at regular corporate rates and income available for distribution to shareholders will be reduced.

Liquidity Risk. The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities or close derivative positions at an advantageous price or in a timely manner. Illiquid or restricted securities cannot be sold immediately because of statutory and contractual restrictions on resale.

Passive Investment Risk. The Fund is not actively managed and therefore the Fund generally will not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Underlying Index or the selling of the security is otherwise required upon a rebalancing of the Underlying Index.

Tracking Error Risk. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. The Fund’s return may not match the return of its Underlying Index for a number of reasons, including differences between the securities held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the Fund’s holding of cash, differences in timing of the accrual of distributions, changes to the Underlying Index or the need to meet various new or existing regulatory requirements. Consequently, the performance of the Fund may diverge from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions, or due to delays of the Fund in purchasing and selling securities. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Derivatives Risk. Derivatives are financial contracts whose value depend on, or are derived from, the value of an underlying asset, reference rate, or index. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain derivative instruments can lose more than the principal amount invested. Derivatives may involve significant risks. Derivatives could result in Fund losses if the underlying references do not perform as anticipated. Derivatives may expose the Fund to additional risks including: the risk of loss due to a derivative position that is imperfectly correlated with the underlying reference it is intended to hedge or replicate (correlation risk); the risk that a counterparty will fail to perform as agreed (counterparty risk); the risk that a hedging strategy may fail to mitigate losses, and may offset gains (hedging risk); the risk that losses may be greater than the amount invested (leverage risk); the risk that the Fund may be unable to sell an investment at an advantageous time or price (liquidity risk); the risk that the investment may be difficult to value (pricing risk); and the risk that the price or value of the investment fluctuates significantly over short periods of time (volatility risk).

Non-Diversification Risk. The Fund is classified as “non-diversified,” which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investments in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

Absence of Active Trading Market Risk. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares May Trade at Prices Different than Net Asset Value Per Share. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares of the Fund may result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares when the market price is at a premium to the NAV or sells shares when the market price is at a discount to the NAV, the shareholder may sustain losses.

Trading Risks. The Fund faces numerous trading risks, including disruption in the creation/redemption process of the Fund and losses from trading in the secondary markets. Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons or due to extraordinary market volatility pursuant to “circuit breaker” rules on the exchange or market. Additionally, an exchange or market may also close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Legal and Regulatory Change Risks. The regulatory environment for investment companies is evolving, and changes in regulation may adversely affect the value of the Fund’s investments and its ability to pursue its trading strategy. The effect of any future regulatory change on the Fund could be substantial and adverse.

Methodology Risks. The Index Provider relies on various sources of information to assess the criteria of issuers included in the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Index Provider can offer assurances that the Underlying Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers or that the included issuers will provide the Fund with the market exposure it seeks.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart and table provide performance information that indicates some of the risks of investing in the Fund. On March 20, 2017, the assets of the Tortoise North American Pipeline Fund, a series of Montage Managers Trust (the “Predecessor Fund”), which had the same portfolio manager as the Fund and has identical investment strategies as the Fund, were transferred to the Fund in a tax-free reorganization. Performance shown for periods prior to March 20, 2017 represent the performance of the Predecessor Fund. The bar chart shows how the Fund’s total returns have varied for annual periods through December 31, 2018. Next to the bar chart are the Fund’s highest and lowest quarterly returns during the period shown on the bar chart. The table illustrates how the Fund’s average annual returns for the 1-year and since inception periods compare with those of a broad measure of market performance and the Underlying Index. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information for the Fund is available on the Fund’s website -- http://etp.tortoiseadvisors.com/tpyp/performance/ -- or by calling 844-TR-INDEX (844-874-6339).
