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 or indirectly, in the speculative trading of a diversified portfolio of commodity interests including futures, option, swap and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, 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”), a limited partnership organized under the partnership laws of the state of New York, 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. The Partnership was authorized to sell an unlimited number of redeemable units (“Redeemable Units”) during its initial offering period. 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 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, 2015, 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. 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 units issued legally. The Master was formed in order to permit 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. As of September 30, 2015, the Partnership’s/Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. 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, 2015. The Master has entered into a foreign exchange brokerage account agreement and a futures brokerage account agreement with MS&Co. The Partnership has entered into a futures brokerage account agreement with MS&Co. and has transferred the brokerage account of the Partnership from Citigroup Global Markets Inc. 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. The Partnership has also 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 receives a monthly selling agent fee equal to 2.0% per year of the Partnership’s adjusted month-end net assets. The selling agent fee received by Morgan Stanley Wealth Management will be shared with the properly registered/licensed financial advisers of Morgan Stanley Wealth Management who sell redeemable units in the Partnership. Effective April 1, 2014, the monthly ongoing selling agent fee was reduced from an annual rate of 5.5% to an annual rate of 3.0%. Effective June 1, 2014, the management fee paid to the Advisor was reduced from an annual rate of 2.0% to an annual rate of 1.5%. Effective October 1, 2014, the monthly ongoing selling agent fee was reduced from an annual rate of 3.0% to an annual rate of 2.0%. As of the same date, the Partnership began paying a fee to the General Partner (formerly, the administrative fee) at an annual rate of 1.0%. The October 1, 2014 fee changes offset each other and, accordingly, there was no change to the aggregate fees incurred by 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 will furnish certain administrative, accounting, regulatory, reporting, tax and other services as agreed from time to time. In addition, the Administrator will maintain certain books and records of the Partnership. The costs of retaining the Administrator will be allocated among the pools operated by the General Partner, including the Partnership.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies: The accompanying financial statements and accompanying notes are unaudited but, in the opinion of the General Partner, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Partnership’s financial condition at September 30, 2015, and the results of its operations and changes in partners’ capital for the three and nine months ended September 30, 2015 and 2014. 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, 2014. The December 31, 2014 information has been derived from the audited financial statements as of and for the year ended December 31, 2014. 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. Certain prior period amounts have been reclassified to conform to current period presentation. In the financial highlights of the Partnership and the Master, the ongoing selling agent fees and clearing fees of the Partnership and the clearing fees of the Master, which were previously included in net realized and unrealized gains (losses) per unit and excluded from expenses per unit are now excluded from net realized and unrealized gains (losses) per unit and included in net investment loss per unit. This information was previously included as footnotes to the financial highlights tables. As of September 30, 2015 and December 31, 2014, 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 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 shall be liable for obligations of the Partnership in excess of its capital contributions and profits, if any, net of distributions or redemptions and losses, if any. 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. Partnership’s Investment: 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 the trade date and open contracts are recorded at fair value 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 Master’s Statements of Financial Condition. Net realized gains or losses and net change in unrealized gains or losses from the preceding period are reported on the Master’s Statements of Income and Expenses and Changes in Partners’ Capital.

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 are shown on the Statements of Income and Expenses and Changes in Partners’ Capital. The customer agreement among the Partnership, the Master and MS&Co. gives, the Partnership and the Master, respectively, 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 on the Statements of Financial Condition as the criteria under Accounting Standards Codification 210-20, “ Balance Sheet Trading and transaction fees are based on the number of trades executed by the Advisor. All trading, exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “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, 2015 and 2014 were 829 and 1,558, respectively. The monthly average number of futures contracts traded during the nine months ended September 30, 2015 and 2014 were 1,236 and 1,764, respectively. The monthly average number of metals forward contracts traded during the three months ended September 30, 2015 and 2014 were 457 and 336, respectively. The monthly average number of forward contracts traded during the nine months ended September 30, 2015 and 2014 were 481 and 551, respectively. The monthly average notional values of currency forward contracts held during the three months ended September 30, 2015 and 2014 were $304,427,503 and $390,495,929, respectively. The monthly average notional values of currency forward contracts held during the nine months ended September 30, 2015 and 2014 were $337,390,511 and $516,402,165, respectively. The following tables summarize the gross and net amounts recognized 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, 2015 and December 31, 2014, 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 on the Master’s Statements of Financial Condition. In the case of exchange-traded contracts, the Master’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements: Master’s Fair Value Measurements. The 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 the 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-dealers or pricing services who derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the periods ended September 30, 2015 and December 31, 2014, 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 nine months ended September 30, 2015 and for the year ended December 31, 2014, there were no transfers of assets or liabilities between Level 1 and Level 2.

Investments, All Other Investments [Abstract]
Financial Instrument Risks	6. Financial Instrument Risks: In the normal course of business, the Partnership, indirectly 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, options 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 be accurately 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 that at any given time approximately 27.3% to 48.8% of the Partnership’s/Master’s contracts are traded OTC. 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 net change in 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 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-upon 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 Master’s 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 that 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. 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 net change in unrealized gains (losses) on metal contracts are included 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 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 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, 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.

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 on the Master’s Statements of Financial Condition. In the case of exchange-traded contracts, the Master’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.
