General	9 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
General	'
	1. General:
	Managed Futures Premier Abingdon L.P. (formerly Abingdon Futures Fund 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 contracts, options, swap and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, metals and softs. The Partnership commenced trading on February 1, 2007. The commodity interests that are 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 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. As of September 30, 2014, all trading decisions for the Partnership are made by Winton Capital Management Limited (the “Advisor”).
	During the three and nine months ended September 30, 2014, the Partnership’s/Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. During prior periods included in this report, Citigroup Global Markets Inc. (“CGM”) also served as a commodity broker.
	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 Diversified Trading Program Without Equities (formerly the Diversified Program), 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 they would be 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.
	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 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 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 Redeemable Units to investors at its discretion. Class Z Units were offered to certain employees of Morgan Stanley Smith Barney and its affiliates (and their family members). Class A Units, Class D Units, and Class Z Units are identical, except that Class D 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 ending 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. Class Z Units are not subject to a monthly ongoing selling agent fee.
	The General Partner is not aware of any material changes to the trading program discussed above during the fiscal quarter ended September 30, 2014.
	During the second quarter of 2013, the Master entered into a foreign exchange brokerage account agreement with MS&Co. The Master commenced foreign exchange trading through an account at MS&Co. on or about May 1, 2013. During the third quarter of 2013, the Master also entered into a futures brokerage account agreement with MS&Co. The Master commenced futures trading through an account at MS&Co. on or about July 22, 2013. Effective October 29, 2013, the Partnership entered into a futures brokerage account agreement with MS&Co. and began transferring the brokerage account of the Partnership from CGM to MS&Co. The Partnership, through its investment in the Master, pays MS&Co. trading fees for the clearing and, where applicable, execution of transactions.
	Effective October 1, 2013, the Partnership ceased paying a brokerage fee to CGM. Also effective October 1, 2013, the Partnership entered into a selling agreement with Morgan Stanley Smith Barney LLC (d/b/a Morgan Stanley Wealth Management). Pursuant to the selling agreement, Morgan Stanley Wealth Management received a selling agent fee equal to an annual rate of (i) 4.5% of the Partnership’s month-end net assets for Class A Units, (ii) 1.875% of the Partnership’s month-end net assets for Class D Units and (iii) 1.125% of the Partnership’s month-end net assets for Class Z Units. The selling agent fee received by Morgan Stanley Wealth Management will be shared with other properly licensed and/or registered selling agents and to financial advisers who have sold Redeemable Units in the Partnership.
	Effective April 1, 2014, the monthly ongoing selling agent fee was reduced from (i) an annual rate of 4.5% to an annual rate of 2.5% of month-end Net Assets for Class A Units, (ii) an annual rate of 1.875% to an annual rate of 1.25% of month-end Net Assets for Class D Units and (iii) an annual rate of 1.125% to an annual rate of 0.5% of month-end Net Assets for Class Z Units.
	Effective October 1, 2014, the monthly ongoing selling agent fee was (i) reduced from an annual rate of 2.50% to an annual rate of 2.00% for Class A Redeemable Units, (ii) reduced from an annual rate of 1.25% to an annual rate of 0.75% for Class D Redeemable Units and (iii) eliminated for Class Z Redeemable Units. As of the same date, the administrative fee increased from an annual rate of 0.50% to an annual rate of 1.00%. The October 1, 2014 fee changes offset each other and, accordingly, there was no change to the aggregate fees incurred by the Partnership.
	Certain prior period amounts have been reclassified to conform to current year presentation. Amounts reported on the Statements of Income and Expenses as ongoing selling agent fees were previously presented as brokerage fees.
	At September 30, 2014 and December 31, 2013, the Partnership owned approximately 29.1% and 29.9%, 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, forwards, swap and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. During the three and nine months ended September 30, 2014, the Master engaged in such trading through a commodity brokerage account maintained with MS&Co. During prior periods covered by this report, the Master engaged in such trading through commodity brokerage accounts maintained with CGM. 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 their capital contribution and profits, if any, net of distributions and losses, if any.
	The accompanying financial statements and accompanying notes are unaudited but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Partnership’s financial condition at September 30, 2014 and December 31, 2013, and the results of its operations and changes in partners’ capital for the three and nine months ended September 30, 2014 and 2013. These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. These financial statements should be read together with the financial statements and notes included in the Partnership’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) for the year ended December 31, 2013.
	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.
	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.
	The Master’s Statements of Financial Condition and Condensed Schedules of Investments as of September 30, 2014 and December 31, 2013 and Statements of Income and Expenses and Changes in Partners’ Capital for the three and nine months ended September 30, 2014 and 2013 are presented below:

Brokers and Dealers [Abstract]	'
Trading Activities	'
	3	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 customer agreement among the Partnership, the Master and MS&Co. gives, and the customer agreements between the Partnership and CGM and the Master and CGM each gave, the Partnership and the Master, respectively, the legal right to net unrealized gains and losses on open futures and open forward contracts. The Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and open forward contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification (“ASC”) 210-20, “Balance Sheet,” have been met.
	Brokerage fees previously paid to CGM were calculated as a percentage of the adjusted net asset value per class on the last day of each month and are affected by trading performance, subscriptions and redemptions.
	Trading and transaction fees are based on the number of trades executed by the Advisor and the Partnership’s percentage ownership in the Master.
	All trading, exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “clearing fees”) are borne by the Master and allocated to its 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 during the three months ended September 30, 2014 and 2013 was 53,426 and 35,193, respectively. The monthly average number of futures contracts traded during the nine months ended September 30, 2014 and 2013 was 50,789 and 40,409, respectively. The monthly average number of metals forward contracts traded during the three months ended September 30, 2014 and 2013 was 1,220 and 2,361, respectively. The monthly average number of metals forward contracts traded during the nine months ended September 30, 2014 and 2013 was 1,002 and 1,539, respectively. The average notional value of currency forward contracts during the three months ended September 30, 2014 and 2013 was $658,593,023 and $709,823,043, respectively. The average notional value of currency forward contracts during the nine months ended September 2014 and 2013 was $635,073,223 and $735,828,725, respectively.
	On January 1, 2013, the Partnership adopted Accounting Standards Update (“ASU”) 2011-11, “Disclosure about Offsetting Assets and Liabilities” and ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 created a new disclosure requirement about the nature of an entity’s rights to setoff and the related arrangements associated with its financial instruments and derivative instruments, while ASU 2013-01 clarified the types of instruments and transactions that are subject to the offsetting disclosure requirements established by ASU 2011-11. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of these disclosures is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (“IFRS”). The new guidance did not have a significant impact on the Partnership’s financial statements.
	The following tables summarize the valuation of the Master’s investments as of September 30, 2014 and December 31, 2013, respectively.

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	4	Fair Value Measurements:
	Partnership’s Investments. The Partnership values its investment in the Master at the Master’s net asset value per unit per Class as calculated by the Master. The Master values its investments as described in Note 2 of the Master’s notes to the annual financial statements as of December 31, 2013.
	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 also 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, there has not been a significant decrease in the volume and level of activity in the Partnership’s Level 2 assets and liabilities.
	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.
	On October 1, 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-04, “Technical Corrections and Improvements,” which makes minor technical corrections and clarifications to ASC 820, “Fair Value Measurements and Disclosures.” When the FASB issued Statement 157 (codified in ASC 820), it conformed the use of the term “fair value” in certain pre-Codification standards but not others. ASU 2012-04 conforms the term’s use throughout the ASC “to fully reflect the fair value measurement and disclosure requirements” of ASC 820. ASU 2012-04 also amends the requirements that must be met for an investment company to qualify for the exemption from presenting a statement of cash flows. Specifically, it eliminates the requirements that substantially all of an entity’s investments be carried at “market value” and that the investments be highly liquid. Instead, it requires substantially all of the entity’s investments to be carried at “fair value” and classified as Level 1 or Level 2 measurements under ASC 820.
	The Partnership values its investment in the Master with no rights or obligations inherent within the ownership interest held by the Partnership based on the end of the day net asset value of the Master (Level 2). The value of the Partnership’s investment in the Master reflects its proportional interest in the Master. As of and for the periods ended September 30, 2014 and December 31, 2013, the Partnership did not hold any derivative instruments that were based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) or priced at fair value using unobservable inputs through the application of the General Partner’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets and liabilities between Level 1 and Level 2.

	Master’s Investments. All commodity interests of the Master (including derivative financial instruments and derivative commodity instruments) are held for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded at fair value (as described below) 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 open 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 and Changes in Partners’ Capital.
	Master’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. Management has concluded that based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.
	GAAP also 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. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Master’s Level 2 assets and liabilities.
	The Master 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.
	The Master considers prices for exchange-traded commodity futures, forwards, options and swaps contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers who derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the periods ended September 30, 2014 and December 31, 2013, the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

Financial Instrument Risks	'
	5	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 forwards, futures, 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 24.4% to 31.2% of the Partnership’s/Master’s contracts are traded OTC.
	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.
	Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/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 Partnership/Master is exposed to a 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 had credit risk and concentration risk during the reporting period and prior periods included in this report, as CGM and/or MS&Co. or their affiliates were the sole counterparties or brokers with respect to the Partnership’s/Master’s assets. Credit risk during the reporting period with respect to exchange-traded instruments was reduced to the extent that, through CGM or MS&Co. or their affiliates, the Partnership’s/Master’s counterparty was an exchange or clearing organization. The Partnership/Master continue to be subject to such risks with respect to MS&Co.
	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, forwards and options positions by sector, margin requirements, gain and loss transactions and collateral positions.
	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.

Critical Accounting Policies	'
	6	Critical Accounting Policies:
	Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires management 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.
	Partnership’s Investments. The Partnership values its investment in the Master at the Master’s net asset value per unit per Class as calculated by the Master. The Master values its investments as described in Note 2 of the Master’s notes to the annual financial statements as of December 31, 2013.
	Partnership’s and the Master’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. Management has concluded that based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.
	GAAP also requires the need to use judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s and the Master’s Level 2 assets and liabilities.
	The Partnership and the Master will separately present purchases, sales, issuances and settlements in their 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.
	The Partnership values investments in the Master with no rights or obligations inherent within the ownership interest held by the Partnership based on the end of the day net asset value of the Master (Level 2). The value of the Partnership’s investment in the Master reflects its proportional interest in the Master. As of and for the periods ended September 30, 2014 and December 31, 2013, the Partnership did not hold any derivative instruments that were based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) or priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
	The Master considers prices for exchange-traded commodity futures, forwards and options contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers who derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the periods ended September 30, 2014 and December 31, 2013, the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
	Futures Contracts. The Master 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 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Master on each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. When the contract is closed, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
	Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Forward foreign currency contracts are valued daily, and the Master’s net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statements of Financial Condition. Net realized gains (losses) and changes in net unrealized gains (losses) on forward foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
	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 net gain (loss) on investments in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
	London Metals Exchange Forward Contracts. Metal contracts traded on the London Metals Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin or zinc. LME contracts traded by the Master are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Master on each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, directly with the LME. Net realized gains (losses) and changes in net unrealized gains (losses) on metal contracts are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
	Investment Company Status. Effective January 1, 2014, the Partnership adopted ASU 2013-08, “Financial Services — Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.” ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company’s status as an investment company. ASU 2013-08 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Partnership’s financial statements. Based on management’s assessment, the Partnership has been deemed to be an investment company since inception. It has all of the fundamental characteristics of an investment company. Although the Partnership does not possess all of the typical characteristics of an investment company, its activities are consistent with those of an investment company.
	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.
	GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Partnership level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. 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 2011 through 2013 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.
	Net Income (Loss) per unit. Net income (loss) per unit for each Class is calculated in accordance with investment company guidance. See Note 2 “Financial Highlights.”
	Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are issued. The General Partner has assessed the subsequent events through the date of issuance and has determined that other than as referenced in Note 1 to the financial statements, there were no subsequent events requiring adjustment of or disclosure in the financial statements.

Accounting Policies [Abstract]	'
Use of Estimates	'
	Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires management 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.
Partnership's Investments	'
	Partnership’s Investments. The Partnership values its investment in the Master at the Master’s net asset value per unit per Class as calculated by the Master. The Master values its investments as described in Note 2 of the Master’s notes to the annual financial statements as of December 31, 2013.
Partnership's and the Master's Fair Value Measurements	'
	Partnership’s and the Master’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. Management has concluded that based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.
	GAAP also requires the need to use judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s and the Master’s Level 2 assets and liabilities.
	The Partnership and the Master will separately present purchases, sales, issuances and settlements in their 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.
	The Partnership values investments in the Master with no rights or obligations inherent within the ownership interest held by the Partnership based on the end of the day net asset value of the Master (Level 2). The value of the Partnership’s investment in the Master reflects its proportional interest in the Master. As of and for the periods ended September 30, 2014 and December 31, 2013, the Partnership did not hold any derivative instruments that were based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) or priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
	The Master considers prices for exchange-traded commodity futures, forwards and options contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers who derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the periods ended September 30, 2014 and December 31, 2013, the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the nine months ended September 30, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
Futures Contracts	'
	Futures Contracts. The Master 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 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Master on each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. When the contract is closed, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
Forward Foreign Currency Contracts	'
	Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Forward foreign currency contracts are valued daily, and the Master’s net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statements of Financial Condition. Net realized gains (losses) and changes in net unrealized gains (losses) on forward foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
	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 net gain (loss) on investments in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
London Metals Exchange Forward Contracts	'
	London Metals Exchange Forward Contracts. Metal contracts traded on the London Metals Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin or zinc. LME contracts traded by the Master are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Master on each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, directly with the LME. Net realized gains (losses) and changes in net unrealized gains (losses) on metal contracts are included in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.
Investment Company Status	'
	Investment Company Status. Effective January 1, 2014, the Partnership adopted ASU 2013-08, “Financial Services — Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.” ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company’s status as an investment company. ASU 2013-08 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Partnership’s financial statements. Based on management’s assessment, the Partnership has been deemed to be an investment company since inception. It has all of the fundamental characteristics of an investment company. Although the Partnership does not possess all of the typical characteristics of an investment company, its activities are consistent with those of an investment company.
Income Taxes	'
	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.
	GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Partnership level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. 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 2011 through 2013 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.
Net Income (Loss) per unit	'
	Net Income (Loss) per unit. Net income (loss) per unit for each Class is calculated in accordance with investment company guidance. See Note 2 “Financial Highlights.”
Subsequent Events	'
	Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are issued. The General Partner has assessed the subsequent events through the date of issuance and has determined that other than as referenced in Note 1 to the financial statements, there were no subsequent events requiring adjustment of or disclosure in the financial statements.
