Accounting Policies [Abstract]
Organization	Managed Futures Premier Warrington L.P. June 30, 2020 (Unaudited) 1. Organization: Managed Futures Premier Warrington L.P. (formerly known as Warrington Fund L.P.) (the “Partnership”) is a limited partnership organized on November 28, 2005, under the partnership laws of the State of New York to engage in the speculative trading of commodity interests including futures and option contracts. The Partnership does not currently intend to, but may in the future, engage in transactions in spot and forward markets. The Partnership primarily trades futures and options in the stock indices sector. The Partnership may also hold U.S. Treasury bills (“T-Bills”). The Partnership commenced trading on February 21, 2006. The commodity interests that are traded by the Partnership are volatile and involve a high degree of market risk. The Partnership privately and continuously offers redeemable units of limited partnership interest (“Redeemable Units”) in the Partnership to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership. Effective as of the close of business on March 31, 2015, Warrington GP, LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership. The General Partner is beneficially owned by Scott C. Kimple. From inception to the close of business on March 31, 2015, Ceres Managed Futures LLC, a Delaware limited liability company, acted as the general partner (“CMF GP”) and commodity pool operator of the Partnership. On January 9, 2015, Scott C. Kimple proposed in a proxy statement (the “Proxy Statement”) filed with the Securities and Exchange Commission (the “SEC”) and distributed to Limited Partners (defined below), that Warrington GP, LLC become the new general partner of the Partnership. The requisite number of each class of limited partnership interests approved the proposals described in the Proxy Statement, and, as a result, Warrington GP, LLC became the new general partner of the Partnership effective as of the close of business on March 31, 2015. CMF GP withdrew as the general partner of the Partnership immediately following Warrington GP, LLC becoming the Partnership’s new general partner. Effective as of the close of business on March 31, 2015, Warrington SLP, LP, a Delaware limited partnership and an affiliate of the General Partner, became a special limited partner of the Partnership (the “Special Limited Partner”) and receives a quarterly profit share allocation equal to 20% of new trading profits from the Partnership in the form of Redeemable Units, subject to a high water mark. All of the trading decisions for the Partnership are made by Warrington Asset Management LLC (the “Advisor”), an affiliate of the General Partner, using the Strategic Trading Program (formerly, the “Core Trading Program”), a proprietary trading program. The General Partner is not aware of any material changes to the trading program discussed above during the fiscal quarter ended June 30, 2020. On June 15, 2011, the Partnership began offering “Class A” Redeemable Units and “Class D” Redeemable Units pursuant to the offering memorandum. All outstanding Redeemable Units on June 15, 2011 were designated Class A Redeemable Units. The rights, powers, duties and obligations associated with the investment in Class A Redeemable Units were not changed. On October 1, 2011, the first Class D Redeemable Units were issued to limited partners of the Partnership (each a “Limited Partner”). Class A Redeemable Units and Class D Redeemable Units will each be referred to as a “Class” and together referred to as the “Classes.” The Class of Redeemable Units that a Limited Partner receives will generally depend upon the amount invested in the Partnership, although the General Partner may determine to offer Class A Redeemable Units or Class D Redeemable Units to investors in its sole discretion. On May 1, 2015, a new share class of units of general partner interest “Class GP” was initiated to accept an investment from the General Partner. During the three months ended June 30, 2020, the Partnership’s commodity brokers were Wedbush Securities, Inc. (“Wedbush”), ADM Investor Services, Inc. (“ADM”) and HSBC Securities (USA) Inc. (“HSBC”), all of whom are registered futures commission merchants. Effective November 27, 2018, the Partnership entered into a commodity futures customer agreement with HSBC (the “HSBC Customer Agreement”); however, the Partnership did not engage in any trading activity through HSBC until September 4, 2019. The Partnership pays HSBC trading fees for the clearing and, if applicable, execution of transactions.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies: The accompanying financial statements and accompanying notes are unaudited but, in the opinion of the General Partner, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Partnership’s financial condition and condensed schedule of investments at June 30, 2020 and December 31, 2019, the results of its operations for the three and six months ended June 30, 2020 and 2019 and changes in partners’ capital for the three and six months ended June 30, 2020 and 2019. These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. You should read these financial statements together with the financial statements and notes included in the Partnership’s Annual Report on Form 10-K filed with the SEC as of and for the year ended December 31, 2019. The December 31, 2019 information has been derived from the audited financial statements as of and for the year ended December 31, 2019. The preparation of financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the General Partner to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates. The General Partner and each Limited Partner share in the profits and losses of the Partnership, after the allocation to the Special Limited Partner, in proportion to the amount of Partnership interest owned by each, except that no Limited Partner shall be liable for obligations of the Partnership in excess of its capital contribution and profits, if any, net of distributions and losses, if any. The Partnership’s trading of futures and options contracts, as applicable, on commodities is done primarily on U.S. commodity exchanges. At various times during the three and six months ended June 30, 2020 and 2019, the Partnership engaged in such trading through commodity brokerage accounts with Wedbush, ADM and HSBC. Due to the nature of commodity trading, the results of operations for the interim periods presented should not be considered indicative of the results that may be expected for the entire year. Partnership’s Investments: The fair value of exchange-traded futures and options contracts is determined by the various exchanges, and reflects the settlement price for each contract as of the close of business on the last business day of the reporting period. All commodity interests are held for trading purposes. The commodity interests are recorded on the trade date and open contracts are recorded at fair value (as described below in Note 5 “Fair Value Measurements”) at the measurement date. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the measurement date. Gains or losses are realized when contracts are liquidated. Unrealized gains or losses on option contracts are included as a component of equity in trading account on the Statements of Financial Condition. Net realized gains or losses and any change in net unrealized gains or losses from the preceding period are reported in the Statements of Income and Expenses. The Partnership had no investments in U.S. government securities as of June 30, 2020. Investment Company Status : Based on the General Partner’s assessment, the Partnership has been deemed to be an investment company since inception. Accordingly, the Partnership follows the investment company accounting and reporting guidance of FASB Accounting Standards Codification Topic 946 and reflects its investments at fair value with unrealized gains and losses resulting from changes in fair value reflected in the Statements of Income and Expenses. Income Taxes: Income taxes have not been provided as each partner is individually liable for the taxes, if any, on its share of the Partnership’s income and expenses. The General Partner concluded that no provision for income tax is required in the Partnership’s financial statements. The Partnership files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The 2017 through 2019 tax years remain subject to examination by U.S. federal and most state tax authorities. The General Partner does not believe that there are any uncertain tax positions that require recognition of a tax liability. There have been no material changes with respect to the Partnership’s critical accounting policies as reported in the Partnership’s Annual Report on Form 10-K as of and for the year ended December 31, 2019.

Trading Activities	4. Trading Activities: The Partnership was formed for the purpose of trading contracts in a variety of commodity interests, including derivative financial instruments and derivative commodity instruments. The results of the Partnership’s trading activities are shown in the Statements of Income and Expenses. The Wedbush Customer Agreement, the ADM Customer Agreement and the HSBC Customer Agreement give the Partnership the legal right to net unrealized gains and losses on open futures and option contracts. The Partnership netted as applicable, for financial reporting purposes, the unrealized gains and losses on open futures and option contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification 210-20, “Balance Sheet,” Ongoing selling agent fees paid to Baird, Morgan Stanley Wealth Management and Credit Suisse Securities (USA) LLC were calculated as a percentage of the Partnership’s adjusted net asset value on the last day of each month and were affected by trading performance, subscriptions and redemptions. Trading and transaction fees are based on the number of trades executed by the Advisor for the Partnership. All trading, exchange, clearing, user, give-up, floor brokerage and National Futures Association (“NFA”) fees (collectively, the “clearing fees”) paid to Wedbush, ADM, HSBC and executing brokers, as applicable are borne by the Partnership. All of the commodity interests owned by the Partnership are held for trading purposes. The monthly average number of option contracts held during the three months ended June 30, 2020 and 2019 were 485 and 1,141, and the six months ended June 30, 2020 and 2019 were 243 and 1,668.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements: Partnership’s Fair Value Measurements . Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. GAAP requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. The General Partner has concluded that based on available information in the marketplace, the Partnership’s Level 1 assets and liabilities are actively traded. The Partnership will separately present purchases, sales, issuances and settlements in its reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and make disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required under GAAP. In August 2018, the FASB issued Accounting Standards Update (ASU) 2018-13, Disclosure Framework-Changes to the Disclosure requirements for Fair Value Measurement, which modifies the disclosure requirements for fair value measurements, primarily as it relates to Level 3 investments. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The effect of adopting this accounting guidance did not have a material impact on the Partnership’s financial statements. The Partnership considers prices for exchange-traded commodity futures and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of futures and certain option contracts for which market quotations are not readily available are priced by broker-dealers that derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the six-month period ended June 30, 2020 and the twelve-month period ended December 31, 2019, the Partnership did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of the General Partner’s assumptions and internal valuation pricing models (Level 3). Any transfers between levels are recognized at the beginning of the period. During the six months ended June 30, 2020 and the twelve months ended December 31, 2019, there were no transfers of assets or liabilities between Level 1 and Level 2.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Financial Instrument Risks	6. Financial Instrument Risks: In the normal course of business, the Partnership is party to financial instruments with off-balance-sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include futures and options, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash balances, to purchase or sell other financial instruments on specific terms at specified future dates, or, in the case of derivative commodity instruments, to have a reasonable possibility to be settled in cash, through physical delivery or with another financial instrument. These instruments may be traded on an exchange or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forward and option contracts. OTC contracts are negotiated between contracting parties and include certain forward, option and swap contracts. Specific market movements of commodities or futures contracts underlying an option cannot accurately be predicted. The purchaser of an option may lose the entire premium paid for the option. The writer, or seller, of an option has unlimited risk. Each of these instruments is subject to various risks similar to those relating to the underlying financial instruments, including market and credit risk. In general, the risks associated with OTC contracts are greater than those associated with exchange-traded instruments because of the greater risk of default by the counterparty to an OTC contract. None of the Partnership’s current contracts are traded OTC, although contracts may be traded OTC in the future. Futures Contracts . The Partnership trades futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of investments, currency or a standardized amount of a deliverable grade commodity, at a specified price on a specified future date, unless the contract is closed before the delivery date or if the delivery quantity is something where physical delivery cannot occur (such as the S&P 500 ® Options . The Partnership may purchase and write (sell), both exchange listed and OTC, options on commodities or financial instruments. An option is a contract allowing, but not requiring, its holder to buy (call) or sell (put) a specific or standard commodity or financial instrument at a specified price during a specified time period. The option premium is the total price paid or received for the option contract. When the Partnership writes an option, the premium received is recorded as a liability in the Statements of Financial Condition and marked to market daily. When the Partnership purchases an option, the premium paid is recorded as an asset in the Statements of Financial Condition and marked to market daily. Net realized gains (losses) and any change in net unrealized gains (losses) on option contracts from the preceding period are included in the Statements of Income and Expenses. Market risk is the potential for changes in the value of the financial instruments traded by the Partnership due to market changes, including interest rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded. The Partnership is exposed to market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. The Partnership’s risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership had credit risk and concentration risk during the reporting period and prior periods included in this report, as Wedbush, ADM and HSBC, or their affiliates, were the sole counterparties or brokers with respect to the Partnership’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through Wedbush, ADM or HSBC, or their affiliates, the Partnership’s counterparty is an exchange or clearing organization. The Partnership’s trading will be concentrated in exchange-traded futures and options on the S&P 500 ® As both a buyer and seller of options, the Partnership pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option. Written options expose the Partnership to potentially unlimited liability; for purchased options, the risk of loss is limited to the premiums paid. Certain written put options permit cash settlement and do not require the option holder to own the reference asset. The Partnership does not consider these contracts to be guarantees. The General Partner monitors and attempts to control the Partnership’s risk exposure on a daily basis through financial, credit and risk management monitoring systems, and, accordingly, believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures and option contracts by sector, margin requirements, gain and loss transactions and collateral positions. The risk to the Limited Partners that have purchased Redeemable Units is limited to the amount of their share of the Partnership’s net assets and undistributed profits. This limited liability is a result of the organization of the Partnership as a limited partnership under New York law. The majority of these financial instruments mature within one year of the inception date. However, due to the nature of the Partnership’s business, these instruments may not be held to maturity.
