Accounting Policies [Abstract]
Partnership Organization	1.    Partnership 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, however, also trade in additional sectors including U.S. Treasury bonds, currencies, gold, silver and energy products. 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.
	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.
	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 collectively 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.
	As of December 31, 2014, all trading decisions for the Partnership are made by Warrington Asset Management, LLC (the “Advisor”). In addition, the Advisor is a special limited partner (in its capacity as special limited partner, the “Special Limited Partner”) of the Partnership. During the year ended December 31, 2014, the Partnership’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.
	The General Partner and each Limited Partner share in the profits and loss 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 option contracts, if applicable, on commodities is done primarily on United States of America and foreign commodity exchanges. During the year ended December 31, 2014, the Partnership engaged in such trading through commodity brokerage accounts maintained with MS&Co. During prior periods included in this report, the Partnership engaged in such trading through commodity brokerage accounts maintained with CGM.
	The Partnership will be liquidated upon the first to occur of the following: December 31, 2025; when the net asset value per Redeemable Unit of any class decreases to less than $400 as of the close of any business day; or under certain other circumstances as defined in the Limited Partnership Agreement of the Partnership (the “Limited Partnership Agreement”). In addition, the General Partner may, in its sole discretion, cause the Partnership to be liquidated if the aggregate net assets of the Partnership decline to less than $1,000,000.

Accounting Policies [Abstract]
Accounting Policies	2.    Accounting Policies:
		a.	Use of Estimates.    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.
		b.	Statement of Cash Flows.    The Partnership is not required to provide a Statement of Cash Flows.
		c.	Partnership’s Investments.    All commodity interests (including derivative financial instruments and derivative commodity instruments) 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) 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 options 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 included in the Statements of Income and Expenses.
	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, 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.
	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 years ended December 31, 2014 and 2013, the Partnership did not hold any derivative instruments for which market quotations were not readily available and which were priced by broker-dealers that derive fair values for those assets from observable inputs (Level 2) or 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). During the years ended December 31, 2014 and 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

		d.	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 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Partnership each business day, depending on the daily fluctuations in the value of the underlying instruments, and are recorded as unrealized gains or losses by the Partnership. When the contract is closed, the Partnership 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 Statements of Income and Expenses.
		e.	Options.    The Partnership may purchase and write (sell) both exchange listed and over-the-counter (“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 changes in net unrealized gains (losses) on option contracts are included in the Statements of Income and Expenses.
		f.	Income Taxes.    Income taxes have not been provided as each partner is individually liable for the taxes, if any, on their 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 has 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 2014 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.
		g.	Investment Company Status.    Effective January 1, 2014, the Partnership adopted Accounting Standards Update (“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 the General Partner’s assessment, the Partnership has been deemed to be an investment company since inception.
		h.	Net Income (Loss) per unit.    Net income (loss) per unit is calculated in accordance with investment company guidance. See Note 6, “Financial Highlights.”
		i.	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 determined that, other than described in Note 8, there were no subsequent events that required adjustment of or disclosure in the financial statements.

Agreements

Commitments and Contingencies Disclosure [Abstract]
Agreements	3.    Agreements:
		a.	Limited Partnership Agreement:
	The General Partner administers the business and affairs of the Partnership including selecting one or more advisors to make trading decisions for the Partnership. The Partnership pays the General Partner a monthly administrative fee in return for its services to the Partnership equal to 1/24 of 2% (1% per year) of month-end Net Assets per Class, for each outstanding Class, of the Partnership. Prior to October 1, 2014, the Partnership paid the General Partner a monthly administrative fee equal to 1/24 of 1% (0.5% per year) of month-end Net Assets per Class, for each outstanding Class, of the Partnership. Month-end Net Assets per Class, for the purpose of calculating administrative fees are Net Assets per Class, as defined in the Limited Partnership Agreement, prior to the reduction of the current month’s management fee, profit share allocation accrual, the administrative fee and any redemptions or distributions as of the end of such month. This fee may be increased or decreased at the discretion of the General Partner.
		b.	Management Agreement:
	The Advisor or one of its affiliates, all of which are controlled by Scott C. Kimple, has served as the Partnership’s commodity trading advisor since inception. The General Partner has entered into a management agreement (the “Management Agreement”) with the Advisor. Prior to the close of business on December 31, 2014, Mr. Kimple, the sole trading principal of Warrington, was employed by Morgan Stanley Smith Barney LLC, doing business as Morgan Stanley Wealth Management (“Morgan Stanley Wealth Management”), a selling agent for the Partnership. As compensation for services, the Partnership pays the Advisor a monthly management fee equal to 1/6 of 1% (2% per year) of month-end Net Assets per Class, for each outstanding Class, managed by the Advisor. Month-end Net Assets per Class, for each outstanding Class, for the purpose of calculating management fees are Net Assets per Class, for each outstanding Class, as defined in the Limited Partnership Agreement, prior to the reduction of the current month’s management fee, profit share allocation accrual, the administrative fee and any redemptions or distributions as of the end of such month. The Management Agreement may be terminated upon notice by either party.
	In addition, the Special Limited Partner receives a quarterly profit share allocation to its capital account in the Partnership in the form of Redeemable Units of the Partnership, the value of which shall be equal to 20% of new trading profits, as defined in the Management Agreement, earned for each outstanding Class by the Special Limited Partner on behalf of the Partnership during each calendar quarter and are issued as Special Limited Partner unit equivalents. The Special Limited Partner will not receive a profit share allocation until the Special Limited Partner recovers the net loss incurred and earns additional new trading profits for the Partnership.
	In allocating substantially all of the assets of the Partnership to the Advisor, the General Partner considers the Advisor’s past performance, trading style, volatility of the markets traded and fee requirements. The General Partner may modify or terminate the allocation of assets to the Advisor at any time.
		c.	Customer Agreement/Selling Agent Agreement:
	Prior to and during part of the third quarter of 2013, the Partnership was party to a Customer Agreement with CGM (the “CGM Customer Agreement”). During the third quarter of 2013, the Partnership entered into a Customer Agreement with MS&Co. (the “MS&Co. Customer Agreement”) and during the fourth quarter of 2013, the Partnership entered into a Selling Agent Agreement with Morgan Stanley Wealth Management (the “Selling Agreement”). The Partnership has terminated the CGM Customer Agreement.
	Under the CGM Customer Agreement, the Partnership paid CGM a monthly brokerage fee equal to (i) 5/16 of 1% (3.75% per year) of month-end Net Assets for Class A Redeemable Units and (ii) 1/12 of 1.50% (1.50% per year) of month-end Net Assets for Class D Redeemable Units, in each case in lieu of brokerage fees on a per trade basis. Month-end Net Assets, for the purpose of calculating brokerage fees were Net Assets, as defined in the Limited Partnership Agreement, prior to the reduction of the current month’s brokerage fees, the profit share allocation accrual, the monthly management fee, the administrative fee and other expenses and any redemptions or distributions as of the end of such month. The Partnership paid for exchange, service, clearing, user, give-up, floor brokerage and National Futures Association (“NFA”) fees (collectively, the “CGM clearing fees”) directly. During the term of the CGM Customer Agreement, all of the Partnership’s assets were deposited in the Partnership’s account at CGM. The Partnership’s cash was deposited by CGM in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations. CGM paid the Partnership interest on 80% of the average daily equity maintained in cash in the Partnership’s brokerage account at a 30-day U.S. Treasury bill rate determined weekly by CGM based on the average non-competitive yield on 3-month U.S. Treasury bills maturing 30 days from the date on which such weekly rate is determined.
	Under the MS&Co. Customer Agreement, the Partnership pays trading fees for the clearing and, where applicable, execution of transactions, as well as exchange, clearing, user, give-up, floor brokerage and NFA fees (collectively, the “MS&Co. clearing fees,” and together with the CGM clearing fees, the “clearing fees”) directly. Clearing fees will be paid for the life of the Partnership, although the rate at which such fees are paid may be changed. All of the Partnership’s assets are deposited in the Partnership’s account at MS&Co. The Partnership’s cash is deposited by MS&Co. in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations. At December 31, 2014 and 2013, the amount of cash held for margin requirements was $18,102,669 and $23,597,971, respectively. MS&Co. has agreed to pay the Partnership interest on 80% of the average daily equity maintained in cash in the Partnership’s brokerage account at the rate equal to the monthly average of the 4-week U.S. Treasury bill discount rate. The MS&Co. Customer Agreement may generally be terminated upon notice by either party.
	Under the Selling Agreement with Morgan Stanley Wealth Management, the Partnership pays Morgan Stanley Wealth Management a monthly ongoing selling agent fee equal to (i) 1/6 of 1% (2% per year) of month-end Net Assets for Class A Redeemable Units and (ii) 1/12 of 0.75% (0.75% per year) of month-end Net Assets for Class D Redeemable Units. For the period from April 1, 2014 to September 30, 2014, the Partnership paid Morgan Stanley Wealth Management a monthly ongoing selling agent fee equal to (i) 5/24 of 1% (2.5% per year) of month-end Net Assets for Class A Redeemable Units and (ii) 1/12 of 1.25% (1.25% per year) of month-end Net Assets for Class D Redeemable Units. Prior to April 1, 2014, the Partnership paid Morgan Stanley Wealth Management a monthly ongoing selling agent fee equal to (i) 5/16 of 1% (3.75% per year) of month-end Net Assets for Class A Redeemable Units and (ii) 1/12 of 1.50% (1.50% per year) of month-end Net Assets for Class D Redeemable Units. Morgan Stanley Wealth Management will pay a portion of its ongoing selling agent fees to other properly licensed and/or registered selling agents and to financial advisors who have sold Redeemable Units. Month-end Net Assets, for the purpose of calculating ongoing selling agent fees are Net Assets, as defined in the Limited Partnership Agreement, prior to the reduction of the current month’s ongoing selling agent fee, management fee, profit share allocation accrual, the administrative fee and other expenses and any redemptions or distributions as of the end of such month.
	Certain prior year amounts have been reclassified to conform to current year presentation. Amounts reported separately on the Statements of Income and Expenses as ongoing selling agent fees and clearing fees were previously combined and presented as brokerage fees.

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 MS&Co. Customer Agreement with the Partnership gives, and the CGM Customer Agreement with the Partnership gave, the Partnership the legal right to net unrealized gains and losses on open futures contracts. The Partnership nets, 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,” have been met.
	Brokerage fees previously paid to CGM 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 numbers of trades executed by the Advisor for the Partnership.
	All of the commodity interests owned by the Partnership are held for trading purposes. The monthly average number of option contracts traded during the years ended December 31, 2014 and 2013 were 7,149 and 10,944, respectively.
	On January 1, 2013, the Partnership adopted 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. The new guidance did not have a significant impact on the Partnership’s financial statements.
	The following tables summarize the valuation of the Partnership’s investments as of December 31, 2014 and 2013:

Financial Instrument Risks	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instrument Risks	7.    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 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 or OTC. Exchange-traded instruments include futures and certain standardized swap, forward and option contracts. 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 be 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 related 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.
	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.
	Market risk is the potential for changes in the value of the financial instruments traded by the Partnership 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 is exposed to a 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, as MS&Co. and/or CGM or their affiliates were 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 MS&Co. and/or CGM, the Partnership’s counterparty is an exchange or clearing organization. The Partnership continues to be subject to such risks with respect to MS&Co.
	The Partnership’s trading will be concentrated in exchange-traded futures and options on the S&P 500 Index and the Dow Jones Industrials Average. Concentration in a limited number of commodity interests may subject the Partnership’s account to greater volatility than if a more diversified portfolio of contracts were traded on behalf of the Partnership.
	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, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions.
	The majority of these 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.

Subsequent Events [Abstract]
Subsequent Events	8.	Subsequent Events:
	On or about January 9, 2015, Scott C. Kimple, a Limited Partner of the Partnership and a principal of the Advisor, proposed in a Proxy Statement, which was filed with the Securities and Exchange Commission and distributed to Limited Partners, that Warrington GP, LLC (“Warrington GP”), an affiliate of the Advisor, become the new general partner of the Partnership. Mr. Kimple also requested in the Proxy Statement that the Limited Partners of the Partnership waive the 90-day notice required for the withdrawal of the General Partner.
	If a majority of each class of the Limited Partners were to vote in favor of the proposals described in the Proxy Statement (the “Proposals”), Warrington GP would be elected the new general partner of the Partnership effective following the close of business on or prior to March 31, 2015, and the 90-day notice requirement for the General Partner’s withdrawal would be waived. In connection with this solicitation, Mr. Kimple resigned as an employee of Morgan Stanley Wealth Management, effective upon the close of business on December 31, 2014. The General Partner consented to Mr. Kimple’s solicitation, but expressed no opinion as to the merit of the Proposals.
	The requisite number of each class of limited partnership interests approved the Proposals, and Warrington GP will become the new general partner of the Partnership effective following the close of the business on March 31, 2015. The General Partner will withdraw as the general partner of the Partnership immediately following Warrington GP becoming the Partnership’s new general partner. The Partnership’s limited partnership agreement will be amended to reflect Warrington GP as the new general partner.
	As a result of the above changes, no Morgan Stanley entity, including the General Partner and MS&Co. will be responsible for the promulgation or implementation of the Partnership’s investment policies, for the activities of the Partnership in general, or for the obligations of Warrington GP to the Partnership.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates.    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.
Statement of Cash Flows	Statement of Cash Flows.    The Partnership is not required to provide a Statement of Cash Flows.
Partnership's Investments		c.	Partnership’s Investments.    All commodity interests (including derivative financial instruments and derivative commodity instruments) 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) 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 options 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 included in the Statements of Income and Expenses.
	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, 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.
	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 years ended December 31, 2014 and 2013, the Partnership did not hold any derivative instruments for which market quotations were not readily available and which were priced by broker-dealers that derive fair values for those assets from observable inputs (Level 2) or 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). During the years ended December 31, 2014 and 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

Futures Contracts	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 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Partnership each business day, depending on the daily fluctuations in the value of the underlying instruments, and are recorded as unrealized gains or losses by the Partnership. When the contract is closed, the Partnership 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 Statements of Income and Expenses.
Options	Options.    The Partnership may purchase and write (sell) both exchange listed and over-the-counter (“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 changes in net unrealized gains (losses) on option contracts are included in the Statements of Income and Expenses.
Income Taxes		f.	Income Taxes.    Income taxes have not been provided as each partner is individually liable for the taxes, if any, on their 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 has 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 2014 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.
Investment Company Status	Investment Company Status.    Effective January 1, 2014, the Partnership adopted Accounting Standards Update (“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 the General Partner’s assessment, the Partnership has been deemed to be an investment company since inception.
Net Income (Loss) per unit	Net Income (Loss) per unit.    Net income (loss) per unit is calculated in accordance with investment company guidance. See Note 6, “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 determined that, other than described in Note 8, there were no subsequent events that required adjustment of or disclosure in the financial statements.
