Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization | 1. Organization: Westport Futures Fund L.P. (the “Partnership”) is a limited partnership organized under the partnership laws of the State of New York on March 21, 1997, to engage, directly and indirectly, in the speculative trading of a diversified portfolio of commodity interests, including futures, options on futures, forwards, options on forwards, spot and swap contracts, cash commodities and any other rights or interests pertaining thereto including interests in commodity pools. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, metals and softs. The Partnership commenced trading on August 1, 1997. The commodity interests that are indirectly traded by the Partnership, through its investment in Rabar 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 privately and continuously offers redeemable units of limited partnership interest (“Redeemable Units”) to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership. Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership. As of December 31, 2016, the General Partner was a wholly-owned subsidiary of Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). MSSB Holdings was 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. All trading decisions for the Partnership are made by Rabar Market Research Inc. (“Rabar” or the “Advisor”). During the periods covered in this report, 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. On December 1, 2012, the Partnership allocated substantially all of its capital to the Master, a limited partnership organized under the partnership laws of the State of Delaware. The Partnership purchased an interest in the Master with cash equal to $31,143,887. The Master permits accounts managed now and in the future by Rabar using the Diversified Program, a proprietary and 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 if the Partnership traded directly and redemption rights are not affected. 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. The financial statements of the Master, including the Condensed Schedules of Investments are contained elsewhere in this report and should be read together with the Partnership’s financial statements. As of December 31, 2016 and 2015, the Partnership owned approximately 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 Partnership will be liquidated upon the first to occur of the following: December 31, 2047; the net asset value per Redeemable Unit decreases to less than $400 per Redeemable Unit 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 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. |

Text Block [Abstract] | |
Agreements | 3. Agreements: a. Limited Partnership Agreement: The General Partner administers the business and affairs of the Partnership. The General Partner has agreed to make capital contributions so that its general partnership interest will be equal to the greater of (1) an amount that will entitle the General Partner to an interest of at least 1% in each material item of the Partnership income, gain, loss, deduction or credit and (2) the greater of (i) 1% of the partners’ contributions or (ii) $25,000. Effective October 1, 2014, the Partnership pays the General Partner a monthly fee in return for its services to the Partnership equal to 1/12 of 1% (1% per year) of adjusted month-end net assets. b. Management Agreement: The General Partner has entered into a management agreement with Rabar, a registered commodity trading advisor (the “Management Agreement”). The Advisor is not affiliated with the General Partner or MS&Co. and is not responsible for the organization or operation of the Partnership. The Partnership pays the Advisor a monthly management fee equal to 1/6 of 1% (2% per year) of month-end Net Assets allocated to the Advisor and an incentive fee payable quarterly equal to 20% of the New Trading Profits, as defined in the Management Agreement, earned by the Advisor for the Partnership. The Advisor will not be paid incentive fees until the Advisor recovers the net loss incurred and earns additional new trading profits for the Partnership. Month-end Net Assets, for the purpose of calculating management fees are Net Assets, as defined in the Limited Partnership Agreement, prior to the reduction of the current month’s incentive fee accrual, the monthly management fee, the General Partner fee and any redemptions or distributions as of the end of such month. The Management Agreement may be terminated upon 30 days’ notice by either party. In allocating substantially all of the assets of the Partnership to the Master, the General Partner considers, among other things, the Advisor’s past performance, trading style, volatility of markets traded and fee requirements. The General Partner may modify or terminate the allocation of assets to the Advisor and may allocate assets to additional advisors at any time. c. Customer Agreement: The Partnership has entered into a customer agreement with MS&Co. (the “Partnership Customer Agreement”). Under the Partnership Customer Agreement and the foreign exchange brokerage account agreement (described in Note 4, “Trading Activities”), the Partnership will pay trading fees for the clearing and, where applicable, the execution of transactions, as well as exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively the “clearing fees”) through its investment in the Master. Clearing fees are allocated to the Partnership based on its proportionate share of the Master. 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 available for trading in commodity interests are deposited in the Partnership’s account at MS&Co. The Partnership’s cash deposited with MS&Co. is held in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations. MS&Co. has agreed to pay the Partnership interest on 80% of the average daily equity maintained in cash in the Partnership’s (or the Partnership’s allocable portion of the Master’s) brokerage account at the rate equal to the monthly average of the 4-week U.S. Treasury bill discount rate. The Partnership Customer Agreement may generally be terminated upon notice by either party. d. Selling Agent Agreement: The Partnership has entered into a selling agent agreement with Morgan Stanley Wealth Management (the “Selling Agreement”). Under the Selling Agreement, the Partnership pays Morgan Stanley Wealth Management a monthly ongoing selling agent fee. Prior to April 1, 2014, the monthly ongoing selling agent fee was paid at a rate equal to 5.25% per year of the month-end Net Assets of the Partnership. Effective April 1, 2014, the monthly ongoing selling agent fee was reduced to 3.0% per year of the month-end Net Assets of the Partnership. Effective October 1, 2014, the monthly ongoing selling agent fee was reduced to 2.0% per year of the month-end Net Assets. Morgan Stanley Wealth Management will pay a portion of its ongoing selling agent fees to other properly registered or exempted 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, the General Partner fee, the incentive fee accrued, other expenses and any redemptions or distributions as of the end of such month. |

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 interests. 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 on the Statements of Income and Expenses. The Master has entered into a futures brokerage account agreement with MS&Co. (the “Master Customer Agreement” and together with the Partnership Customer Agreement, the “Customer Agreements”). The Customer Agreements give the Partnership and the Master the legal right to net unrealized gains and losses on open futures and forward contracts. The Partnership and the Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and 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 and the Partnership’s ownership of the Master. Professional fees and other expenses are borne by the Master and allocated to the Partnership, and also directly charged at the Partnership level. All other fees are charged at the Partnership level. For disclosures regarding the Master’s trading activities, see Note 4, “Trading Activities,” in the attached Master’s financial statements. |

Financial Highlights | 7. Financial Highlights: Financial highlights for the limited partner class as a whole for the years ended December 31, 2016, 2015 and 2014 were as follows: 2016 2015 2014 Per Redeemable Unit Performance (for a unit outstanding throughout the year):* Net realized and unrealized gains (losses) $ 25.45 $ (133.14) $ 246.78 Net investment loss (67.29) (76.18) (83.77) Increase (decrease) for the year (41.84) (209.32) 163.01 Net asset value per Redeemable Unit, beginning of year 961.71 1,171.03 1,008.02 Net asset value per Redeemable Unit, end of year $ 919.87 $ 961.71 $ 1,171.03 2016 2015 2014 Ratios to Average Limited Partners’ Capital: Net investment loss ** (7.1) % (7.1) % (7.9) % Operating expense 7.3 % 7.1 % 8.0 % Incentive fees - % - % - % Total expenses 7.3 % 7.1 % 8.0 % Total return: Total return before incentive fees (4.4) % (17.9) % 16.2 % Incentive fees - % - % - % Total return after incentive fees (4.4) % (17.9) % 16.2 % * Net investment loss per Redeemable Unit is calculated by dividing the expenses net of interest income by the average number of Redeemable Units outstanding during the year. The net realized and unrealized gains (losses) per Redeemable Unit is a balancing amount necessary to reconcile the change in net asset value per Redeemable Unit with the other per unit information. ** Interest income allocated from the Master less total expenses. The above ratios and total return may vary for individual investors based on the timing of capital transactions during the year. Additionally, these ratios are calculated for the limited partner class using the limited partners’ share of income, expenses and average partners’ capital of the Partnership and includes the income and expenses allocated from the Master. |
Financial Instrument Risks

Investments, All Other Investments [Abstract] | |
Financial Instrument Risks | 8. 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, 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, swap and option 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. 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 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/Partnership are exposed to market risk equal to the value of the futures and forward contracts purchased and unlimited liability on such contracts sold short. See Note 8, “Financial Instrument Risks”, of the attached Master’s financial statements for risks relating to financial instruments and derivatives that are traded by the Master. 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 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/Master’s business, these instruments may not be held to maturity. |
