Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Potomac Futures Fund L.P. (the “Partnership”) is a limited partnership organized on March 14, 1997 under the partnership laws of the State of New York to engage, directly and indirectly, in the speculative trading of a diversified portfolio of commodity interests including futures, option, swap and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, metals and softs. The commodity interests that are indirectly traded by the Partnership through its investment in CMF Campbell Master Fund L.P. (the “Master”) are volatile and involve a high degree of market risk. The General Partner (defined below) may also determine to invest up to all of the Partnership’s assets in United States (“U.S.”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. The Partnership is authorized to sell an unlimited number of redeemable units of limited partnership interest (“Redeemable Units”). The Partnership privately and continuously offers 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. All trading decisions for the Partnership are made by Campbell & Company, Inc. (the “Advisor”). On January 1, 2005, 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. The Partnership purchased 173,788.6446 units of the Master with cash equal to $172,205,653 and a contribution of open commodity futures and forward contracts with a fair value of $1,582,992. The units of the Master are used solely for accounting purposes and do not represent legally distinct units. The Master permits accounts managed by the Advisor using the Campbell Managed Futures Portfolio (formerly, Financial, Metal and Energy Large Portfolio), a 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 is not aware of any material changes to the trading program discussed above during the fiscal quarter ended September 30, 2016. As of March 22, 2016, the Partnership began offering two classes of limited partnership interests, Class A Redeemable Units and Class Z Redeemable Units. All Redeemable Units issued prior to February 29, 2016 were deemed “Class A Redeemable Units.” The rights, liabilities, risks, and fees associated with investment in the Class A Redeemable Units were not changed. Class A Redeemable Units are available to taxable U.S. individuals and institutions, U.S. tax exempt individuals and institutions, and non-U.S. investors. Class Z Redeemable Units were first issued on July 1, 2016 at $1,000 per Redeemable Unit. Class Z Redeemable Units are offered to limited partners who receive advisory services from Morgan Stanley Wealth Management and may also be offered to certain employees of Morgan Stanley and/or its subsidiaries (and their family members). Class A Redeemable Units and Class Z Units are identical, except that Class Z Redeemable Units are not subject to monthly ongoing selling agent fees. Generally, a limited partner in the Master withdraws all or part of its capital contribution and undistributed profits, if any, from the Master as of the end of any month (the “Redemption Date”) after a request has been made to the General Partner at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner in the Master elects to redeem and informs the Master. However, a limited partner in the Master may request a withdrawal as of the end of any day if such request is received by the General Partner at least three days in advance of the proposed withdrawal day. During the reporting periods ended September 30, 2016 and 2015, the Partnership’s and the Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. The Partnership and the Master also deposit a portion of their cash in a non-trading account at JPMorgan Chase Bank, N.A. As of September 30, 2016 and December 31, 2015, the Partnership owned 100% of the Master. The Partnership intends to continue to invest substantially all of its assets in the Master. The performance of the Partnership is directly affected by the performance of the Master. The Master’s trading of futures, forward, swap and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. The Master engages in such trading through a commodity brokerage account maintained with MS&Co. The Master’s Statements of Financial Condition, including Condensed Schedules of Investments and Statements of Income and Expenses and Changes in Partners’ Capital, are included herein. The Master has entered into a foreign exchange brokerage account agreement and a futures brokerage account agreement with MS&Co. The Partnership has also entered into a futures brokerage account agreement with MS&Co. The Partnership, through its investment in the Master, pays MS&Co. (or will reimburse MS&Co., if previously paid) its allocable share of all trading fees for the clearing and, where applicable, execution of transactions as well as exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “clearing fees”). The Partnership has also entered into a selling agreement with Morgan Stanley Smith Barney LLC (doing business as Morgan Stanley Wealth Management) (“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 equal to 2.0% per year of the Partnership’s adjusted month-end net assets for Class A Redeemable Units. Class Z Redeemable Units are not subject to the ongoing selling agent fee. The ongoing selling agent fee received by Morgan Stanley Wealth Management will be shared with the properly registered/licensed financial advisors of Morgan Stanley Wealth Management who sell Redeemable Units in the Partnership. In July 2015, the General Partner delegated certain administrative functions to SS&C Technologies, Inc., a Delaware corporation, currently doing business as SS&C GlobeOp (the “Administrator”). Pursuant to a Master Services Agreement, the Administrator furnishes certain administrative, accounting, regulatory reporting, tax and other services as agreed from time to time. In addition, the Administrator maintains certain books and records of the Partnership. The cost of retaining the Administrator is allocated among the pools operated by the General Partner, including the Partnership.

Trading Activities	4. Trading Activities: The Partnership was formed for the purpose of trading contracts in a variety of 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 is shown in the Partnership’s Statements of Income and Expenses. The futures brokerage account agreements with MS&Co. give the Partnership and the Master the legal right to net unrealized gains and losses on open futures and on open forward contracts. The Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and on open forward contracts in the Statements of Financial Condition as the criteria under ASC 210-20, “Balance Sheet” Trading and transaction fees are based on the number of trades executed by the Advisor for the Master. All clearing fees paid to MS&Co. are borne by the Master and allocated to 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, 2016 and 2015 were 1,164 and 829, respectively. The monthly average number of futures contracts traded during the nine months ended September 30, 2016 and 2015, were 1,148 and 1,236, respectively. The monthly average number of metals forward contracts traded during the three months ended September 30, 2016 and 2015 were 219 and 457, respectively. The monthly average number of metals forward contracts traded during the nine months ended September 30, 2016 and 2015 were 279 and 481, respectively. The monthly average notional values of currency forward contracts held during the three months ended September 30, 2016 and 2015 were $205,968,375 and $304,427,503, respectively. The monthly average notional values of currency forward contracts held during the nine months ended September 30, 2016 and 2015 were $265,147,825 and $337,390,511, respectively. The following tables summarize the gross and net amounts relating to assets and liabilities of the Master’s derivatives and their offsetting subject to master netting arrangements or similar agreements as of September 30, 2016 and December 31, 2015, respectively.

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

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

Financial Instrument Risks	6. Financial Instrument Risks: In the normal course of business, the Partnership, through its investment in the Master, is party to financial instruments with off-balance-sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include 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 on 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 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. The General Partner estimates at any given time approximately 20.4% to 42.8% of the Partnership’s/Master’s contracts are traded OTC. Futures Contracts. Forward Foreign Currency Contracts. London Metals Exchange Forward Contracts. The Master does not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations from changes in market prices of investments held. Such fluctuations are included in total trading results in the Master’s Statements of Income and Expenses and Changes in Partners’ Capital. 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 Master due to market changes, including interest and foreign exchange rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded. The Master is exposed to 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 has credit risk and concentration risk, as MS&Co. or an MS&Co. affiliate is the sole counterparty or broker with respect to the Partnership’s/Master’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or an MS&Co. affiliate, the Partnership’s/Master’s counterparty is an exchange or clearing organization. The General Partner monitors and attempts to control the Partnership’s/Master’s risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership/Master may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, forward 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.

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