Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Orion Futures Fund L.P. (the “Partnership”) is a limited partnership organized on March 22, 1999, 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, livestock, indices, U.S. and non-U.S. Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner” or with respect to Transtrend Master (defined below), the “Trading Manager”) and commodity pool operator of the Partnership. As of January 1, 2017, the General Partner became a wholly-owned subsidiary of Morgan Stanley Domestic Holdings, Inc. (“MSD Holdings”). MSD 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 January 1, 2017, the General Partner was a wholly-owned subsidiary of Morgan Stanley Smith Barney Holdings LLC. All trading decisions are made for the Partnership by Winton Capital Management Limited (“Winton”), Transtrend B.V. (“Transtrend”), Willowbridge Associates Inc. (“Willowbridge”) and Systematica Investments Limited (“Systematica”) (each an “Advisor” and, collectively, the “Advisors”), each of which is a registered commodity trading advisor. Each Advisor is allocated a portion of the Partnership’s assets to manage. The Partnership invests the portion of its assets allocated to each of the Advisors either directly, through an individually managed account, or indirectly, through investments in the Funds. In addition, the General Partner may allocate the Partnership’s assets to additional non-major On June 1, 2011, the Partnership began offering “Class A” Redeemable Units and “Class Z” Redeemable Units pursuant to the offering memorandum. All Redeemable Units issued prior to June 1, 2011 were deemed Class A Redeemable Units. The rights, powers, duties and obligations associated with investment in Class A Redeemable Units were not changed. Class Z Redeemable Units were first issued on August 1, 2011. 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/or its subsidiaries (and their family members). Class A Redeemable Units and Class Z 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 upon a subscription will generally depend upon the status of the limited partner, although the General Partner may determine to offer a particular Class of Redeemable Units to investors at its discretion. During the reporting periods ended March 31, 2017 and 2016, the Partnership’s/Funds’ commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. The Partnership/Funds also deposit a portion of their cash in a non-trading Systematica directly trades the Partnership’s assets allocated to it through a managed account in the name of the Partnership pursuant to Systematica’s BlueTrend Program. The Partnership, CMF Winton Master L.P. (“Winton Master”), CMF TT II, LLC (formerly, Morgan Stanley Smith Barney TT II, LLC) (“Transtrend Master”) and CMF Willowbridge Master Fund L.P. (“Willowbridge Master”) have entered into futures brokerage account agreements and foreign exchange brokerage account agreements with MS&Co. Winton Master, Transtrend Master and Willowbridge Master are collectively referred to as the “Funds.” Effective March 1, 2014, the Partnership entered into a futures brokerage account agreement with MS&Co. (the “Customer Agreement”) and ceased paying brokerage commissions to MS&Co. Under the Customer Agreement, the Partnership pays MS&Co. (or will reimburse MS&Co. if previously paid) its allocable share of trading fees for the clearing and, where applicable, the execution of transactions, as well as its allocable share of exchange, clearing, user, give-up non-trading 4-week 4-week Effective March 1, 2014, the Partnership entered into a new selling agent agreement with Morgan Stanley Wealth Management (as amended, the “Selling Agreement”). Pursuant to the Selling Agreement, Morgan Stanley Wealth Management receives a monthly ongoing selling agent fee. Prior to October 1, 2014, the amount of the ongoing selling agent fee was calculated by multiplying the Partnership’s (i) round-turn futures transactions by $18.00 each, swaps by up to an equivalent amount and options transactions by $9.00 each per side, with respect to Class A Redeemable Units and (ii) round-turn futures transactions by $3.00 each, swaps by up to an equivalent amount and options transactions by $1.50 each per side, with respect to Class Z Redeemable Units. Effective October 1, 2014, the ongoing selling agent fee was (i) reduced to $15.00 each for futures transactions and up to an equivalent amount for swaps and $7.50 each per side for options transactions, with respect to Class A Redeemable Units and (ii) eliminated with respect to Class Z Redeemable Units. The ongoing selling agent fee amount is reduced by applicable floor brokerage fees. Morgan Stanley Wealth Management may pay an ongoing selling agent fee to other properly licensed and/or registered selling agents who sell Redeemable Units, and such additional selling agents may share all or a substantial portion of such fees with their properly registered or exempted financial advisors who have sold Redeemable Units. The General Partner fees, management fees, incentive fees and professional fees of the Partnership are allocated proportionally to each Class based on the net asset value of the Class. 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.

Investment in the Funds	6. Investment in the Funds: On November 1, 2004, the assets allocated to Winton for trading were invested in Winton Master, a limited partnership organized under the partnership laws of the State of New York. The Partnership purchased 35,389.8399 units of Winton Master with cash equal to $33,594,083 and a contribution of open commodity futures and forwards contracts with a fair value of $1,795,757. Winton Master permits accounts managed by Winton using the Winton Futures Program (formerly, the Winton Diversified Program as applied without equities), a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the general partner of Winton Master. Individual and pooled accounts currently managed by Winton, including the Partnership, are permitted to be limited partners of Winton Master. The General Partner and Winton believe that trading through this structure promotes efficiency and economy in the trading process. The General Partner and Winton have agreed that Winton will trade the Partnership’s assets allocated to Winton at a level that is up to 1.5 times the amount of assets allocated. On June 1, 2011, the Partnership allocated a portion of its assets with cash equal to $384,370,435 to Transtrend Master, a limited liability company organized under the limited liability company laws of the State of Delaware. Transtrend Master permits accounts managed by Transtrend using the Diversified Trend Program-Enhanced Risk Profile (US Dollar), a proprietary, systematic trading system, to invest together in one trading vehicle. Individual and pooled accounts managed by Transtrend, including the Partnership, are permitted to be non-managing On August 1, 2014, the assets allocated to Willowbridge for trading were invested in Willowbridge Master, a limited partnership organized under the partnership laws of the State of New York. The Partnership purchased 9,633.9313 units of Willowbridge Master with cash equal to $21,000,000. Willowbridge Master permits accounts managed by Willowbridge using its wPraxis Futures Trading Approach, a proprietary, discretionary trading system, to invest together in one trading vehicle. The General Partner is also the general partner of Willowbridge Master. Individual and pooled accounts currently managed by Willowbridge, including the Partnership, are permitted to be limited partners of Willowbridge Master. The General Partner and Willowbridge believe that trading through this structure promotes efficiency and economy in the trading process. The General Partner and Willowbridge have agreed that Willowbridge will trade the Partnership’s assets at a level that is up to three times the amount of the assets allocated. The General Partner is not aware of any material changes to any of the trading programs discussed above during the fiscal quarter ended March 31, 2017. The Funds’ and the Partnership’s trading of futures, forward, swap, and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. The Funds and the Partnership engage in such trading through commodity brokerage accounts maintained with MS&Co. Generally, a limited partner/member in the Funds withdraws all or part of its capital contribution and undistributed profits, if any, from the Funds as of the end of any month (the “Redemption Date”) after a request has been made to the General Partner/Trading Manager at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner/member elects to redeem and informs the Funds. However, for all Funds other than Winton Master, a limited partner/member may request a withdrawal as of the end of any day if such request is received by the General Partner/Trading Manager at least three days in advance of the proposed withdrawal day. Management fees, ongoing selling agent fees, General Partner fees and incentive fees are charged at the Partnership level, except for management and incentive fees payable to Transtrend which are charged at the Transtrend Master level. Clearing fees are borne by the Funds and allocated to the Funds’ limited partners/non-managing At March 31, 2017, the Partnership owned approximately 46.7% of Winton Master, 94.8% of Transtrend Master and 78.6% of Willowbridge Master. At December 31, 2016, the Partnership owned approximately 51.4% of Winton Master, 94.9% of Transtrend Master and 76.5% of Willowbridge Master.

Financial Instrument Risks	7. Financial Instrument Risks: In the normal course of business, the Partnership and the Funds are party to financial instruments with off-balance over-the-counter Futures Contracts Forward Foreign Currency Contracts. London Metals Exchange Forward Contracts. Options marked-to-market marked-to-market As both a buyer and seller of options, the Partnership/Funds pay or receive a premium at the outset and then bear the risk of unfavorable changes in the price of the contract underlying the option. Written options expose the Partnership/Funds 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/Funds do not consider these contracts to be guarantees. Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/Funds 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 and the Funds are exposed to market risk equal to the value of the futures and forward contracts held 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/Funds’ risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Partnership’s/Funds’ Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s/Funds’ risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Funds to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Funds have 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 and the Funds’ 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/Funds’ counterparty is an exchange or clearing organization. The General Partner monitors and attempts to control the Partnership’s/Funds’ 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/Funds 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, exchange-cleared swaps, forward and option contracts 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/Funds’ business, these instruments may not be held to maturity. 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. In the ordinary course of business, the Partnership/Funds enter into contracts and agreements that contain various representations and warranties and which provide general indemnifications. The Partnership’s/Funds’ maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Partnership/Funds. The Partnership/Funds consider the risk of any future obligation relating to these indemnifications to be remote.
