Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Ceres Tactical Commodity 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 and 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 significant 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 sectors traded include energy, grains, livestock, metals and softs. 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 (“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 NL Master (as defined below) and Aquantum Master (as defined below). The General Partner was also the Trading Manager of Harbour Square Master (as defined below). The General Partner is 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. As of June 30, 2019, all trading decisions are made for the Partnership by Millburn Ridgefield Corporation (“Millburn”), Ospraie Management, LLC (“Ospraie”), Aquantum GmbH (“Aquantum”), Pan Capital Management L.P. (“Pan”), and Northlander Commodity Advisors LLP (“Northlander”) (each, an “Advisor” and, collectively, the “Advisors”), each, a registered commodity trading advisor. On November 30, 2018, the Partnership fully redeemed its investment in MB Master Fund L.P. (“MB Master”). Also effective November 30, 2018, Aventis Asset Management, LLC (“Aventis”) ceased to act as a commodity trading advisor to the Partnership. On March 31, 2019, the Partnership fully redeemed its investment in CMF Harbour Square Master Fund LLC (“Harbour Square Master”). Also effective March 31, 2019, Harbour Square Capital Management LLC (“Harbour Square”) ceased to act as a commodity trading advisor to the Partnership. 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. References herein to the “Advisors” may also include, as relevant, Harbour Square and Aventis. The Advisors are not affiliated with one another, are not affiliated with the General Partner and MS&Co. 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 on 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. During the reporting periods ended June 30, 2019 and 2018, 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 deposited a portion of their cash in non-trading Millburn, Ospraie and Pan 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, Ospraie’s Commodity Program and Pan’s Energy Trading Program, respectively. The Partnership, CMF NL Master Fund LLC (“NL Master”) and CMF Aquantum Master Fund LLC (“Aquantum Master”) have entered, and (prior to their respective terminations) Harbour Square Master and MB Master had entered, into futures brokerage account agreements with MS&Co. NL Master and Aquantum Master are collectively referred to as the “Funds.” References herein to the Funds may also include, as relevant, Harbour Square Master and MB Master. 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, the execution of transactions as well as exchange, user, give-up, 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 each 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.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements: Partnership’s and the Funds’ 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 The Partnership and the Funds consider prices for commodity futures, 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 pricing services that derive fair values for those assets and liabilities from observable inputs (Level 2). As of June 30, 2019 and December 31, 2018 and for the periods ended June 30, 2019 and 2018, the Partnership and the Funds 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).

Investment in the Funds	6. Investment in the Funds: On April 1, 2019, the Partnership allocated a portion of its assets to NL Master, a limited liability company organized under the limited liability company laws of the State of Delaware. NL Master permits accounts managed by Northlander using Northlander’s Commodity Program, a proprietary, discretionary trading system, to invest together in one trading vehicle. The General Partner is also the trading manager of NL Master. Individual and pooled accounts currently managed by Northlander, including the Partnership, are permitted to be members of NL Master. The Trading Manager and Northlander believe that trading through this master/feeder structure should promote efficiency and economy in the trading process. On December 1, 2018, the Partnership allocated a portion of its assets to Aquantum, which were managed and traded directly by Aquantum pursuant to Aquantum’s Commodity Spread Program through a trading account in the Partnership’s name from December 1, 2018 until May 31, 2019. Effective June 1, 2019, the assets allocated to Aquantum were transferred into Aquantum Master, a limited liability company organized under the limited liability company laws of the State of Delaware, through which they are managed and traded by Aquantum pursuant to the same strategy. Aquantum Master permits accounts managed by Aquantum using Aquantum’s Commodity Spread Program, a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the trading manager of Aquantum Master. Individual and pooled accounts currently managed by Aquantum, including the Partnership, are permitted to be members of Aquantum Master. The Trading Manager and Aquantum believe that trading through this master/feeder structure should promote efficiency and economy in the trading process. 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. Effective November 30, 2018, the Partnership fully redeemed its investment in MB Master. 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 permitted accounts managed by Harbour Square using Harbour Square’s Discretionary Energy Program, a proprietary, discretionary trading system, to invest together in one trading vehicle. Effective March 31, 2019, the Partnership fully redeemed its investment in Harbour Square Master. The General Partner is not aware of any material changes to the trading programs discussed above or in Note 1, “Organization” during the fiscal quarter ended June 30, 2019. 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. Generally, a limited partner/member in the Funds may withdraw 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 date. 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 June 30, 2019, the Partnership owned approximately 25.9% of NL Master and 53.9% of Aquantum Master. At December 31, 2018, the Partnership owned approximately 68.7% of Harbour Square 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.

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 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/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 The General Partner/Trading Manager 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/Trading Manager to statistically analyze actual trading results with risk-adjusted 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.
