Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Managed Futures Premier Abingdon L.P. (the “Partnership”) is a limited partnership organized on November 8, 2005, under the partnership laws of the State of New York, to engage, directly or indirectly, in the speculative trading of a diversified portfolio of commodity interests including futures, option, swap and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, lumber, metals and softs. The Partnership commenced trading on February 1, 2007. The commodity interests that are indirectly traded by the Partnership through its investment in CMF Winton Master L.P. (the “Master”) are volatile and involve a high degree of market risk. The General Partner (defined below) may also determine to invest up to all of the Partnership’s assets in United States (“U.S.”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. The Partnership privately and continuously offers redeemable units of limited partnership interest in the Partnership (“Redeemable Units”) to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership. Ceres Managed Futures 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 wholly owned by Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). MSSB Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. Prior to June 28, 2013, Morgan Stanley indirectly owned a majority equity interest in MSSB Holdings and Citigroup Inc. indirectly owned a minority equity interest in MSSB Holdings. Prior to July 31, 2009, the date as of which MSSB Holdings became its owner, the General Partner was wholly owned by Citigroup Financial Products Inc., a wholly owned subsidiary of Citigroup Global Markets Holdings Inc., the sole owner of which is Citigroup Inc. All trading decisions for the Partnership are made by Winton Capital Management Limited (the “Advisor”). During the reporting periods ended June 30, 2016 and 2015, the Partnership’s and the Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. The Partnership and the Master also deposit a portion of their cash in non-trading accounts at JPMorgan Chase Bank, N.A. On February 1, 2007, the Partnership allocated substantially all of its capital to the Master, a limited partnership organized under the partnership laws of the State of New York, having the same investment objective as the Partnership. The Partnership purchased 9,017.0917 units of the Master with cash equal to $12,945,000. The Master permits accounts managed by the Advisor using the Winton Futures Program (formerly, the Winton Diversified Program, as applied without equities), the Advisor’s proprietary, systematic trading program, to invest together in one trading vehicle. The General Partner is also the general partner of the Master. Individual and pooled accounts currently managed by the Advisor, including the Partnership, are permitted to be limited partners of the Master. The General Partner and the Advisor believe that trading through this master/feeder structure promotes efficiency and economy in the trading process. Expenses to investors as a result of the investment in the Master are approximately the same as if the Partnership traded directly, and redemption rights are not affected. The General Partner and the Advisor agreed that the Advisor will trade the Partnership’s assets allocated to the Advisor at a level that is up to 1.5 times the amount of assets allocated. A limited partner in the Master may withdraw all or part of its capital contribution and undistributed profits, if any, from the Master as of the end of any month (the “Redemption Date”) after a request has been made to the General Partner at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner in the Master elects to redeem and informs the Master. The General Partner is not aware of any material changes to the trading program discussed above during the fiscal quarter ended June 30, 2016. On April 1, 2011, the Partnership began offering “Class A” Redeemable Units, “Class D” Redeemable Units and “Class Z” Redeemable Units pursuant to the offering memorandum. All Redeemable Units issued prior to April 1, 2011 were deemed Class A Redeemable Units. The rights, liabilities, risks, and fees associated with investment in the Class A Redeemable Units did not change. “Class D” Redeemable Units and “Class Z” Redeemable Units were first issued on April 1, 2011 and August 1, 2011, respectively. Class A, Class D and Class Z will each be referred to as a “Class” and collectively referred to as the “Classes.” The Class of Redeemable Units that a limited partner receives upon a subscription will generally depend upon the amount invested in the Partnership or the status of the limited partner, although the General Partner may determine to offer any Class of Redeemable Units to investors at its discretion. Class Z Redeemable Units are offered to limited partners who receive advisory services from Morgan Stanley Smith Barney LLC (doing business as Morgan Stanley Wealth Management) (“Morgan Stanley Wealth Management”) and certain employees of Morgan Stanley and its subsidiaries (and their family members). Class A Redeemable Units, Class D Redeemable Units, and Class Z Redeemable Units are identical, except that Class D Redeemable Units are subject to a monthly ongoing selling agent fee equal to 1/12th of 0.75% (a 0.75% annual rate) of the net assets of Class D as of the end of each month, which differs from the Class A monthly ongoing selling agent fee of 1/12th of 2.00% (a 2.00% annual rate) of the net assets of Class A as of the end of each month. Class Z Redeemable Units are not subject to a monthly ongoing selling agent fee. At June 30, 2016 and December 31, 2015, the Partnership owned approximately 42.9% and 38.9%, respectively, of the Master. The Partnership intends to continue to invest substantially all of its assets in the Master. The performance of the Partnership is directly affected by the performance of the Master. The Master’s trading of futures, forward, swap and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. The Master engages in such trading through a commodity brokerage account maintained with MS&Co. The Master’s Statements of Financial Condition, Condensed Schedules of Investments and Statements of Income and Expenses and Changes in Partners’ Capital are included herein. The General Partner and each limited partner share in the profits and losses of the Partnership in proportion to the amount of Partnership interest owned by each, except that no limited partner is liable for obligations of the Partnership in excess of its capital contributions and profits, if any, net of distributions or redemptions and losses, if any. The Master has entered into a foreign exchange brokerage account agreement and a futures brokerage account agreement with MS&Co. The Partnership has also entered into a futures brokerage account agreement with MS&Co. The Partnership, through its investment in the Master, pays MS&Co. (or will reimburse MS&Co., if previously paid) its allocable share of all trading fees for the clearing and, where applicable, execution of transactions as well as exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “clearing fees”). The Partnership has also entered into a selling agreement with Morgan Stanley Wealth Management (as amended, the “Selling Agreement”). Pursuant to the Selling Agreement, Morgan Stanley Wealth Management is paid a monthly ongoing selling agent fee at the rates described above. The ongoing selling agent fee received by Morgan Stanley Wealth Management is shared with the properly registered/exempted financial advisors of Morgan Stanley Wealth Management who sell Class A and/or Class D Redeemable Units. In July 2015, the General Partner delegated certain administrative functions to SS&C Technologies, Inc., a Delaware corporation, currently doing business as SS&C GlobeOp (the “Administrator”). Pursuant to a master services agreement, the Administrator furnishes certain administrative, accounting, regulatory, reporting, tax and other services as agreed from time to time. In addition, the Administrator maintains certain books and records of the Partnership. The cost of retaining the Administrator is allocated among the pools operated by the General Partner, including the Partnership.

Trading Activities	4. Trading Activities: The Partnership was formed for the purpose of trading commodity interests, including derivative financial instruments and derivative commodity instruments. The Partnership invests substantially all of its assets through a “master/feeder” structure. The Partnership’s pro- rata share of the results of the Master’s trading activities are shown in the Statements of Income and Expenses. The futures brokerage account agreements with MS&Co. give the Partnership and the Master the legal right to net unrealized gains and losses on open futures and forward contracts. The Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and forward contracts on its Statements of Financial Condition as the criteria under ASC 210-20, “Balance Sheet,” Trading and transaction fees are based on the number of trades executed by the Advisor for the Master and the Partnership’s percentage ownership of the Master. All clearing fees paid to MS&Co. are borne by the Master and allocated to the Master’s limited partners, including the Partnership. All of the commodity interests owned by the Master are held for trading purposes. The monthly average number of futures contracts traded by the Master during the three months ended June 30, 2016 and 2015 was 31,670 and 47,675, respectively. The monthly average number of futures contracts traded by the Master during the six months ended June 30, 2016 and 2015 was 35,826 and 48,538, respectively. The monthly average number of metals forward contracts traded by the Master during the three months ended June 30, 2016 and 2015 was 930 and 1,380, respectively. The monthly average number of metals forward contracts traded by the Master during the six months ended June 30, 2016 and 2015 was 819 and 1,205, respectively. The average notional value of currency forward contracts traded by the Master during the three months ended June 30, 2016 and 2015 was $613,596,023 and $602,291,493, respectively. The average notional value of currency forward contracts traded by the Master during the six months ended June 30, 2016 and 2015 was $603,010,884 and $585,562,096, respectively.

There is no collateral posted by MS&Co. and as such, in the event of default by MS&Co., the Master is exposed to the amount shown in the Master’s Statements of Financial Condition. In the case of exchange-traded contracts, the Master’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements: Master’s Fair Value Measurements The fair value of exchange-traded futures and forward 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. The fair value of foreign currency forward contracts is extrapolated on a forward basis from the spot prices quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period from various exchanges. The fair value of non-exchange-traded foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as input the spot prices, interest rates, and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period. U.S. Treasury bills are valued at the last available bid price received from independent pricing services as of the close of the last business day of the reporting period. The Master considers prices for exchange-traded commodity futures and forward contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of U.S. Treasury bills and non-exchange-traded forward contracts for which market quotations are not readily available are priced by broker quotes or pricing services that derive fair values for those assets and liabilities from observable inputs (Level 2). As of June 30, 2016 and December 31, 2015 and for the periods ended June 30, 2016 and 2015, the Master 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). Transfers between levels are recognized at the end of the reporting period. During the reporting periods, there were no transfers of assets or liabilities between Level 1 and Level 2.

Investments, All Other Investments [Abstract]
Financial Instrument Risks	6. Financial Instrument Risks: In the normal course of business, the Partnership, through its investment in the Master, is party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include futures, forwards, options and swaps, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash balances, or to purchase or sell other financial instruments at 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, a swap execution facility or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forward, option and swap contracts. Certain swap contracts may also be traded on a swap execution facility or OTC. OTC contracts are negotiated between contracting parties and also include certain forward and option 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 instrument, 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. The General Partner estimates that, at any given time, approximately 21.2% to 30.3% of the Master’s contracts are traded OTC. Futures Contracts Forward Foreign Currency Contracts London Metals Exchange Forward Contracts The Master does not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations from changes in market prices of investments held. Such fluctuations are included in total trading results in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital. Market risk is the potential for changes in the value of the financial instruments traded by the Master due to market changes, including interest and foreign exchange 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 Master is exposed to market risk equal to the value of futures and forward 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/Master’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/Master’s risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Master to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Master has credit risk and concentration risk, as MS&Co. or an MS&Co. affiliate is the sole counterparty or broker with respect to the Partnership’s/Master’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or an MS&Co. affiliate, the Partnership’s/Master’s counterparty is an exchange or clearing organization. The General Partner monitors and attempts to control the Partnership’s/Master’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/Master 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 forward 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 consequence 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/Master’s business, these instruments may not be held to maturity.

There is no collateral posted by MS&Co. and as such, in the event of default by MS&Co., the Master is exposed to the amount shown in the Master’s Statements of Financial Condition. In the case of exchange-traded contracts, the Master’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.
