Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization | 1. Organization: Ceres Tactical Commodity L.P. (formerly, Managed Futures Premier Aventis II L.P.) (the “Partnership”) is a limited partnership organized on April 20, 2005 under the partnership laws of the State of New York to engage, directly or indirectly, in the speculative trading of commodity interests on U.S. and international futures, options on futures and forward markets. The Partnership may also engage, directly or indirectly, in swap transactions and other derivative transactions with the approval of the General Partner (as defined below). Initially, the Partnership’s investment strategy focused on energy and energy-related investments. While the Partnership is expected to continue to have exposure to energy and energy-related markets, such trading will no longer be the Partnership’s primary focus. Therefore, the Partnership’s past trading performance will not necessarily be indicative of future results. The commodity interests that are traded by the Partnership, directly or indirectly through its investment in the Funds (as defined below) are volatile and involve a high degree of market risk. The General Partner may also determine to invest up to all of the Partnership’s assets (directly or indirectly through its investment in the Funds) 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. During the initial offering period, the Partnership sold 11,925 redeemable units of limited partnership interest in the Partnership (“Redeemable Units”). The Partnership commenced trading on September 6, 2005. The Partnership privately and continuously offers 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 and is the trading manager (the “Trading Manager”) of Harbour Square Master (as defined below). The General Partner is a wholly-owned As of September 30, 2018, all trading decisions are made for the Partnership by Aventis Asset Management, LLC (“Aventis”), Millburn Ridgefield Corporation (“Millburn”), Ospraie Management LLC (“Ospraie”) and Harbour Square Capital Management LLC (“Harbour Square”) (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 individually managed accounts, or indirectly, through its investment in the Funds. The Advisors are not affiliated with one another, are not affiliated with the General Partner and MS&Co. (as defined below) and are not responsible for the organization or operation of the Partnership. As of June 13, 2018, the Partnership began offering three classes of limited partnership interests, Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units. All Redeemable Units issued prior to October 31, 2016 were deemed “Class A Redeemable Units.” Class Z Redeemable Units were first issued on January 1, 2017. The rights, liabilities, risks and fees associated with investment in the Class A Redeemable Units were not changed. Class D Redeemable Units were first issued July 1, 2018. The rights, liabilities, risks, and fees associated with investment in the Class A Redeemable Units and Class Z Redeemable Units were not changed. Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units will each be referred to as a “Class” and collectively referred to as the “Classes.” Class A Redeemable Units and Class D Redeemable Units are available to taxable U.S. individuals and institutions, U.S. tax exempt individuals and institutions and non-U.S. month-end month-end During the reporting periods ended September 30, 2018 and 2017, the Partnership’s/Funds’ commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. During prior periods included in this report, the Partnership/Funds also deposited a portion of their cash in non-trading Millburn and Ospraie directly trade the Partnership’s assets allocated to each Advisor through managed accounts in the name of the Partnership pursuant to Millburn’s Commodity Program and Ospraie’s Commodity Program, respectively. MB Master Fund L.P. (“MB Master”) and CMF Harbour Square Master Fund LLC (“Harbour Square Master”) have entered into futures brokerage account agreements with MS&Co. MB Master and Harbour Square Master are collectively referred to as the “Funds.” The Partnership’s/Funds’ trading of futures, forward, swap and option contracts, if applicable, on commodities is done primarily on U.S. commodity exchanges and foreign commodity exchanges. The Partnership/Funds engage in such trading through commodity brokerage accounts maintained with MS&Co. The Partnership has entered into futures brokerage account agreements with MS&Co. The Partnership, directly and through its investment in the Funds, 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, user, give-up, The Partnership has entered into a selling agreement (as amended, the “Selling Agreement”) with Morgan Stanley Wealth Management. Pursuant to the Selling Agreement, the Partnership pays Morgan Stanley Wealth Management a monthly ongoing selling agent fee at the rates described above. The ongoing selling agent fee received by Morgan Stanley Wealth Management is shared with the properly registered or exempted financial advisors of Morgan Stanley Wealth Management who have sold Class A and Class D 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. |

Schedule of Investments [Abstract] | |
Investment in the Funds | 6. Investment in the Funds: On February 1, 2013, the Partnership allocated substantially all of its capital to MB Master, a limited partnership organized under the partnership laws of the State of Delaware. MB Master permits accounts managed by Aventis using its Aventis Diversified Commodity Strategy, a proprietary, discretionary trading system, to invest together in one trading vehicle. The General Partner is also the general partner of MB Master. Individual and pooled accounts currently managed by Aventis, including the Partnership, are permitted to be limited partners of MB Master. The General Partner and Aventis believe that trading through this master/feeder structure should promote efficiency and economy in the trading process. On January 1, 2018, the Partnership allocated a portion of its assets to Harbour Square Master, a limited liability company organized under the limited liability company laws of the State of Delaware. Harbour Square Master permits accounts managed by Harbour Square using Harbour Square’s Discretionary Energy Program, a proprietary, discretionary trading system, to invest together in one trading vehicle. The General Partner is also the trading manager of Harbour Square Master. Individual and pooled accounts currently managed by Harbour Square, including the Partnership, are permitted to be members of Harbour Square Master. The Trading Manager and Harbour Square believe that trading through this structure should promote efficiency and economy in the trading process. The Trading Manager and Harbour Square have agreed that Harbour Square will trade the Fund’s assets allocated to Harbour Square Master at a level that is up to 1.5 times the amount of the assets allocated. The amount of leverage may be changed in the future. The General Partner is not aware of any material changes to the trading programs discussed above during the fiscal quarter ended September 30, 2018. The Funds’ and the Partnership’s trading of futures, forward and option contracts, as 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, 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, General Partner fees, ongoing selling agent fees and incentive fees are charged at the Partnership level. All clearing fees paid to MS&Co. are borne directly by the Partnership for its direct trading. In addition, clearing fees are borne by the Funds and allocated to the Funds’ limited partners/members, including the Partnership. Professional fees are borne by the Funds and allocated to the Partnership, and also charged directly at the Partnership level. At September 30, 2018, the Partnership owned approximately 48.8% of MB Master and 56.6% of Harbour Square Master. Prior to the close of business on December 31, 2017, the Partnership owned approximately 89.3% of MB Master. It is the Partnership’s intention to continue to invest in the Funds. The performance of the Partnership is directly affected by the performance of the Funds. Expenses to investors as a result of the investment in the Funds are approximately the same as they would be if the Partnership traded directly and redemption rights are not affected. Summarized information reflecting the total assets, liabilities and partners’ capital of the Funds is shown in the following tables: September 30, 2018 Total Assets Total Liabilities Total Capital MB Master $ 15,927,110 $ 434,768 $ 15,492,342 Harbour Square Master 23,661,573 2,625,728 21,035,845 December 31, 2017 Total Assets Total Liabilities Total Capital MB Master $ 87,348,208 $ 9,978,681 $ 77,369,527 Summarized information reflecting the net investment income (loss), total trading results and net income (loss) of the Funds is shown in the following tables: For the three months ended September 30, 2018 Net Investment Total Trading Income (Loss) Results Net Income (Loss) MB Master $ 22,573 $ (408,652) $ (386,079) Harbour Square Master 68,750 (1,067,004) (998,254) For the nine months ended September 30, 2018 Net Investment Total Trading Income (Loss) Results Net Income (Loss) MB Master $ 21,503 $ (363,256) $ (341,753) Harbour Square Master 210,173 (190,943) 19,230 For the three months ended September 30, 2017 Net Investment Total Trading Income (Loss) Results Net Income (Loss) MB Master $ (202,137) $ 3,661,231 $ 3,459,094 For the nine months ended September 30, 2017 Net Investment Total Trading Income (Loss) Results Net Income (Loss) MB Master $ (609,805) $ 1,402,859 $ 793,054 Summarized information reflecting the Partnership’s investments in and the Partnership’s pro-rata share of the results of operations of the Funds is shown in the following table: September 30, 2018 For the three months ended September 30, 2018 % of Expenses Net Partners’ Fair Income Clearing Professional Income Investment Redemptions Funds Capital Value (Loss) Fees Fees (Loss) Objective Permitted MB Master 12.41 % $ 7,570,923 $ (159,866) $ 36,765 $ 8,211 $ (204,842) Commodity Portfolio Monthly Harbour Square Master 19.56 % 11,939,643 (571,553) 21,226 10,133 (602,912) Commodity Portfolio Monthly Total $ 19,510,566 $ (731,419) $ 57,991 $ 18,344 $ (807,754) September 30, 2018 For the nine months ended September 30, 2018 % of Expenses Net Partners’ Fair Income Clearing Professional Income Investment Redemptions Funds Capital Value (Loss) Fees Fees (Loss) Objective Permitted MB Master 12.41 % $ 7,570,923 $ (83,209) $ 150,809 $ 24,820 $ (258,838) Commodity Portfolio Monthly Harbour Square Master 19.56 % 11,939,643 76,484 42,538 30,899 3,047 Commodity Portfolio Monthly Total $ 19,510,566 $ (6,725) $ 193,347 $ 55,719 $ (255,791) December 31, 2017 For the three months ended September 30, 2017 % of Expenses Net Partners’ Fair Income Clearing Professional Income Investment Redemptions Fund Capital Value (Loss) Fees Fees (Loss) Objective Permitted MB Master 99.95 % $ 69,682,811 $ 3,394,771 $ 400,850 $ 14,023 $ 2,979,898 Commodity Portfolio Monthly Total $ 69,682,811 $ 3,394,771 $ 400,850 $ 14,023 $ 2,979,898 December 31, 2017 For the nine months ended September 30, 2017 % of Expenses Net Partners’ Fair Income Clearing Professional Income Investment Redemptions Fund Capital Value (Loss) Fees Fees (Loss) Objective Permitted MB Master 99.95 % $ 69,682,811 $ 1,690,890 $ 1,086,506 $ 42,131 $ 562,253 Commodity Portfolio Monthly Total $ 69,682,811 $ 1,690,890 $ 1,086,506 $ 42,131 $ 562,253 |

Financial Instrument Risks | 7. Financial Instrument Risks: In the normal course of business, the Partnership and the Funds are parties to financial instruments with off-balance-sheet over-the-counter Futures 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. Futures-style options. 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 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/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 are counterparties or brokers with respect to the Partnership’s/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 mitigate 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, 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. |
