Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Ceres Tactical Global L.P. (formerly, Ceres Tactical Currency L.P.) (the “Partnership”) is a Delaware limited partnership organized in 1999 to engage primarily in the speculative trading of futures contracts, options on futures and forward contracts, and forward contracts on physical commodities and other commodity interests, including, but not limited to, foreign currencies, financial instruments, metals, energy, and agricultural products (collectively, “Futures Interests”) (refer to Note 9, “Financial Instruments”). The Futures Interests that are traded by the Partnership, either directly, through individually managed accounts, or indirectly, through its investment in the Funds (as defined below), are volatile and involve a high degree of market risk. The General Partner (as 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. Prior to the close of business on December 31, 2017, the Partnership was one of the Morgan Stanley Spectrum series of funds, comprised of the Partnership, Morgan Stanley Smith Barney Spectrum Select L.P., Morgan Stanley Smith Barney Spectrum Strategic L.P. and Morgan Stanley Smith Barney Spectrum Technical L.P. Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (“Ceres” or the “General Partner”) and commodity pool operator of the Partnership, and as the commodity pool operator and general partner or trading manager (in such capacity, the “Trading Manager”) of each Fund (as defined below). As of January 1, 2017, Ceres became 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 business. Prior to January 1, 2017, the General Partner was a wholly-owned subsidiary of Morgan Stanley Smith Barney Holdings LLC.

As of and after October 1, 2018, Mesirow has undertaken to perform the Initial Advisory Agreement and be bound by its terms in every way as if it were the original party to it in place of Cambridge. References herein to the Trading Advisor or the Trading Advisors may also include, as relevant, Mesirow or Cambridge. Each Trading Advisor is allocated a portion of the Partnership’s assets to manage. During periods covered by this report, the Partnership’s and the Funds’ commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. JPMorgan Chase Bank, N.A. (“JPMorgan”) may also act as a foreign exchange forward or swap counterparty for the Partnership/Funds. The Partnership and the Funds deposited a portion of their cash in non-trading Effective October 10, 2018, the Partnership changed its name from Ceres Tactical Currency L.P. to Ceres Tactical Global L.P. CMF AE Capital Master Fund LLC, a Delaware limited liability company (“AE Capital Master Fund”) and Cambridge Master Fund L.P., a Delaware limited partnership (“Cambridge Master Fund” and collectively with AE Capital Master Fund the “Funds”), and the Partnership, have each entered into a futures brokerage account agreement with MS&Co. AE Capital Master Fund and Cambridge Master Fund have also each entered into a foreign exchange prime brokerage agreement with MS&Co. The Partnership has also entered into a futures brokerage account agreement and a foreign exchange prime brokerage agreement with MS&Co.

Greenwave began trading the assets directly pursuant to the Greenwave Flagship Plus Program through a managed account in the Partnership’s name. The General Partner and Greenwave have agreed that Greenwave will trade at a level of up to 2.0 times the portion of the Partnership’s assets allocated to Greenwave. Effective July 12, 2017 Cambridge Master Fund entered into certain agreements with JPMorgan in connection with trading in forward foreign currency contracts on behalf of Cambridge Master Fund and indirectly, the Partnership. These agreements include a foreign exchange and bullion authorization agreement (“FX Agreement”), an International Swap Dealers Association, Inc. master agreement (“Master Agreement”), a schedule to the Master Agreement, a 2016 credit support annex for variation margin to the schedule and an institutional account agreement.

Pursuant to the Assignment Agreement, all references to Cambridge were replaced by references to Mesirow, and all references to “Investment Manager” are deemed to refer to Mesirow. On October 10, 2018, Cambridge Master Fund and JPMorgan entered into an amendment, dated as of October 10, 2018 (the “ISDA Amendment”), effective as of October 1, 2018, to the schedule to the Master Agreement, dated as of July 12, 2017, between Cambridge Master Fund and JPMorgan. Pursuant to the ISDA Amendment, all references to Cambridge were replaced by references to Mesirow. As of January 1, 2018, units of limited partnership interest (“Unit(s)”) of the Partnership are being offered in two classes (each, a “Class” or collectively, the “Classes”): Class A Units and Class Z Units. Class A Units and Class Z Units are identical, except that Class Z Units are not subject to the monthly ongoing placement agent fee. All Units issued prior to January 1, 2018 were deemed “Class A Units.” The rights, liabilities, risks, and fees associated with investment in the Class A Units were not changed. Class Z Units are offered to limited partners who receive advisory services from Morgan Stanley Smith Barney LLC, doing business as Morgan Stanley Wealth Management (“Morgan Stanley Wealth Management”) and may also be offered to certain employees of Morgan Stanley and/or its subsidiaries (and their family members). Class Z Units were first issued on April 1, 2018. The Partnership will terminate on December 31, 2035 regardless of financial condition at such time, or at an earlier date if certain conditions occur as defined in the Partnership’s 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. Effective January 1, 2018, the General Partner pays or reimburses the Partnership, from the General Partner fee it receives from the Partnership, the ordinary administrative expenses of the Partnership, to the extent these expenses exceed 0.85% annually of the net assets of the Partnership. This includes the expenses related to the engagement of the Administrator. Prior to January 1, 2018, the General Partner fully reimbursed the Partnership for these expenses.

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).

Investment in the Funds	6. Investment in the Funds: On or about February 1, 2018, the Partnership allocated a portion of its assets to AE Capital for trading through investment in AE Capital Master Fund, a Delaware limited liability company. AE Capital Master Fund permits accounts managed by AE Capital using its AE Systematic FX Fund Program, a proprietary, discretionary trading system, to invest together in one trading vehicle. Individual and pooled accounts currently managed by AE Capital, including the Partnership, are permitted to be limited partners of AE Capital Master Fund. The General Partner and AE Capital believe that trading through this master/feeder structure promotes efficiency and economy in the trading process. On November 1, 2012, the Partnership’s assets allocated to Cambridge for trading were invested in Cambridge Master Fund, a limited partnership organized under the partnership laws of the State of Delaware. As of and after October 1, 2018, Mesirow had undertaken to perform the Initial Advisory Agreement and be bound by its terms in every way as if it were the original party to it in place of Cambridge. Prior to October 1, 2018, Cambridge Master Fund permitted accounts managed by Cambridge using the Cambridge Asian Markets Alpha Programme and, from October 1, 2013, Cambridge Emerging Markets Alpha Programme, each a proprietary, systematic trading program, to invest together in one trading vehicle. The General Partner is also the general partner of Cambridge Master Fund. Individual and pooled accounts that were managed by Mesirow, including the Partnership, were permitted to be limited partners of Cambridge Master Fund. The General Partner and Mesirow believed that trading through this master/feeder structure would promote efficiency and economy in the trading process. The General Partner and Mesirow agreed that Mesirow would trade the Partnership’s assets allocated to Mesirow at a level that was up to 1.5 times the amount of assets allocated. The Partnership fully redeemed its investment in Cambridge Master Fund on December 31, 2018. The General Partner is not aware of any material changes to any of the trading programs discussed above or in Note 1, “Organization” during the year ended December 31, 2018. Generally, a limited partner/member in a Fund withdraws all or part of its capital contribution and undistributed profits, if any, from the Fund 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 Fund. However, for each Fund 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, ongoing placement agent fees, General Partner fees and incentive fees are charged at the Partnership level. Clearing fees are borne by the Funds and allocated to the Funds’ limited partners/members, including the Partnership. Effective January 1, 2018, clearing fees are also borne by the Partnership directly. Professional fees are borne by the Funds and allocated to the Partnership, and effective January 1, 2018, also charged directly at the Partnership level. Effective January 1, 2018, the General Partner reimburses the Partnership for clearing fees and professional fees to the extent that these fees exceed 0.85% annually of the net assets of the Partnership. At December 31, 2018, the Partnership owned approximately 7.6% of AE Capital Master Fund. Prior to the close of business on December 31, 2017, the Partnership owned approximately 22.9% of Cambridge Master Fund. It is the Partnership’s intention to continue to invest in AE Capital Master Fund. 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 the redemption rights are not affected.

The net realized and unrealized gains (losses) per Unit is a balancing amount necessary to reconcile the change in net asset value per Unit with the other per unit information. ** Interest income 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 limited partners’ capital of the Partnership, and include the income and expenses allocated from the Fund(s).

Financial Instruments

Financial Instruments	12 Months Ended

Investments, All Other Investments [Abstract]
Financial Instruments	9. Financial Instruments: The Partnership and the Funds trade Futures Interests. Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price. Futures Interests are open commitments until the settlement date, at which time they are realized. They are valued at fair value, generally on a daily basis, and the unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the Statements of Financial Condition as a net unrealized appreciation or depreciation on open futures contracts or net unrealized appreciation or depreciation on open forwards contracts. The resulting net change in unrealized gains and losses is reflected in “Net change in unrealized gains (losses) on open contracts” and “Net change in unrealized gains (losses) on open contracts allocated from the Funds” from one period to the next in the Statements of Income and Expenses. The Partnership’s/Funds’ contracts are accounted for on a trade-date basis. Gains or losses are realized when contracts are liquidated and are determined using the first-in, first-out The fair value of an exchange-traded contract is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined. If an exchange-traded contract could not have been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated. In general, the risks associated with non-exchange non-exchange The Partnership also has credit risk because MS&Co. acts as the commodity futures broker, or the counterparty, with respect to most of the Partnership’s assets. Exchange-traded futures and exchange-traded forward contracts are fair valued on a daily basis, with variations in value settled on a daily basis. With respect to the Partnership’s non-exchange non-exchange non-exchange 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 and forward contracts by sector, margin requirements, gain and loss transactions and collateral positions. The U.S. Treasury bills and Futures Interests traded by the Partnership and the Funds involve varying degrees of related market risk. Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently in its earnings, whether realized or unrealized, and cash flow. Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled option contracts are settled daily through variation margin. Gains and losses on non-exchange non-exchange In the ordinary course of business, the Partnership and the 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 and the Funds consider the risk of any future obligation relating to these indemnifications to be remote.
