Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Ceres Classic L.P. (formerly, Managed Futures Premier Graham L.P.) (the “Partnership”) is a Delaware limited partnership organized in 1998 to engage primarily in the speculative trading of futures contracts, options on futures and forward contracts, 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 4, “Financial Instruments”). 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. 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. 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. Morgan Stanley Smith Barney LLC is doing business as Morgan Stanley Wealth Management (“Morgan Stanley Wealth Management”). This entity currently acts as the placement agent (the “Placement Agent”) for the Partnership. Morgan Stanley Wealth Management is a principal subsidiary of MSD Holdings. During the periods covered by this report, the Partnership’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. MS&Co. also acts as the counterparty on all trading of foreign currency forward contracts. MS&Co. is a wholly-owned subsidiary of Morgan Stanley. The Partnership deposited a portion of its cash in a non-trading bank account at JPMorgan Chase Bank, N.A. Effective October 2, 2020, the Partnership changed its name from Managed Futures Premier Graham L.P. to Ceres Classic L.P. As of December 31, 2020, Units of the Partnership are being offered in two share classes (each, a “Class” or collectively, the “Classes”). A Limited Partner will initially receive Class A Units in the Partnership, provided, that certain investors (other than ERISA/IRA investors) who subscribe for Units on a consulting basis, the General Partner and certain employees of Morgan Stanley and/or its subsidiaries (and their family members) may be designated to hold Class Z Units. The Partnership previously offered Units in Class D, however, no Limited Partners hold Class D Units as of December 31, 2020, and Class D Units are no longer offered. Each of Class A and Z U n The General Partner may, at its discretion, offer additional Classes of Units as described in the private placement memorandum of the Partnership, as amended from time to time (the “Memorandum”). Ceres is required to maintain a 1% minimum interest in the equity of the Partnership and income (losses) are shared by Ceres and the limited partners based on their proportional ownership interest. The General Partner has 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.

Placement Agent Fees. From July 1, 2020 to December 31, 2020, the Partnership paid Morgan Stanley Wealth Management, or any other placement agent or sub-placement agent, an annualized rate equal to 1.00% with respect to Class A Units. Prior to July 1, 2020, the Partnership paid Morgan Stanley Wealth Management, or any other placement agent or sub-placement agent, an annualized rate equal to 2.00% with respect to Class A Units. The Placement Agent pays a portion of the ongoing placement agent fees it receives from the Partnership to the Morgan Stanley Financial Advisor or Private Wealth Advisor responsible for selling the Units to the relevant limited partners. Certain limited partners (other than ERISA/IRA investors) may be deemed to hold Class Z Units. Class Z Units are not subject to ongoing placement agent fees. As of November 1, 2018, the Partnership entered into an alternative investment placement agent agreement (the “Harbor Selling Agreement”), by and among the Partnership, the General Partner, Morgan Stanley Distribution Inc. (“MSDI”), and Harbor Investment Advisory, LLC, a Maryland limited liability company (“Harbor”), which supersedes and replaces the alternative investment selling agent agreement, dated January 19, 2018, between the Partnership, the General Partner and Harbor.

Pursuant to the brokerage agreement with MS&Co., to the extent that such trading results in unrealized gains or losses, these amounts are offset for the Partnership and are reported on a net basis in the Statements of Financial Condition.

Trading Advisor	3. Trading Advisors: Ceres, on behalf of the Partnership, has retained Graham Capital Management L.P. (“Graham”) to make all trading decisions for the Partnership, provided that, as of January 1, 2021, Ceres has retained Graham, Winton Capital Management Limited (“WCM”), EMC Capital Advisors, LLC (“EMC”) and Campbell & Company, LP (“Campbell”) as the commodity trading advisors to the Partnership (each, a “Trading Advisor” and collectively, the “Trading Advisors”). Ceres is responsible for selecting additional commodity trading advisors from time to time and for replacing Trading Advisors as it deems necessary. Trading advisors can be added, removed or replaced at any time by Ceres, or Ceres may determine to adjust the allocation of assets to each Trading Advisor, without the consent of, or advance notice to, the Limited Partners. Compensation to the Trading Advisors by the Partnership consists of a management fee and an incentive fee as follows: Management Fee — th th th Effective as of January 1, 2021, the Partnership pays WCM a flat-rate monthly fee equal to 1/12 th Effective as of January 1, 2021, the Partnership pays Campbell a flat ra t th Effective as of January 1, 2021, the Partnership pays EMC a flat rate monthly fee equal to 1/12 th Incentive Fee — Effective as of January 1, 2021, the Partnership pays WCM a quarterly incentive fee equal to 20% of new trading profits (as defined in the applicable management agreement) earned by WCM in each quarterly period. Pursuant to the management agreement with WCM, no incentive fee will be paid to WCM with respect to the Partnership until it has (i) recouped a certain loss carryforward and (ii) earned new trading profits (as defined in the applicable management agreement) from and after January 1, 2021. The loss carryforward applied to the Partnership will be adjusted according to the Partnership’s assets allocated to WCM as of January 1, 2021. Effective as of January 1, 2021, the Partnership pays Campbell a quarterly incentive fee equal to 20% of trading profits (as defined in the applicable management agreement) earned by Campbell in each quarterly period. Effective as of January 1, 2021, the Partnership pays EMC a quarterly incentive fee equal to 20% of trading profits (as defined in the applicable management agreement) earned by EMC in each quarterly period. Trading profits represent the amount by which profits from trading in Futures Interests exceed losses after ongoing placement agent, management and administrative and General Partner’s fees are deducted. When the Trading Advisor experiences losses with respect to net assets as of the end of such period, the Trading Advisor must recover such losses before the Trading Advisor is eligible for an incentive fee in the future. Cumulative trading losses are adjusted on a pro-rated basis for the amount of each month’s net redemptions.

Financial Instruments

Investments, All Other Investments [Abstract]
Financial Instruments	4. Financial Instruments: The Partnership trades Futures Interests. Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price. 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. The General Partner estimates that, at any given time, approximately 21.1% to 46.3% of the Partnership’s contracts are traded over-the-counter. In general, the risks associated with non-exchange-traded contracts are greater than those associated with exchange-traded contracts because of the greater risk of default by the counterparty to a non-exchange-traded contract. The Partnership has credit risk associated with counterparty nonperformance. As of the date of the financial statements, the credit risk associated with the instruments in which the Partnership trades is limited to the unrealized gain amounts reflected in the Statements of Financial Condition. 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-traded forward currency contracts, there are no daily settlements of variation in value, nor is there any requirement that an amount equal to the net unrealized gains (losses) on such contracts be segregated. However, the Partnership is required to meet margin requirements with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account and U.S. Treasury bills held at MS&Co., for the benefit of MS&Co. With respect to those non-exchange-traded forward currency contracts, the Partnership is at risk to the ability of MS&Co., the sole counterparty on all such contracts, to perform. The Partnership has a netting agreement with MS&Co. The primary terms are based on industry standard master netting agreements. This agreement, which seeks to reduce both the Partnership’s and MS&Co.’s exposure on non-exchange-traded forward currency contracts, should materially decrease the Partnership’s credit risk in the event of MS&Co.’s bankruptcy or insolvency. The General Partner monitors and attempts to mitigate the Partnership’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 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 U.S. Treasury bills, futures, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions. The Futures Interests traded, and the U.S. Treasury bills held, by the Partnership 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 and exchange-traded forward contracts are settled daily through variation margin. Gains and losses on non-exchange-traded forward currency contracts are settled upon termination of the contract. In the ordinary course of business, the Partnership enters into contracts and agreements that contain various representations and warranties and which provide general indemnifications. The Partnership’s maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Partnership. The General Partner considers the risk of any future obligation relating to these indemnifications to be remote.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Trading Activities	5. Trading Activities: The Partnership’s objective is to profit from speculative trading in Futures Interests. Therefore, the Trading Advisors will take speculative positions in Futures Interests where it feels the best profit opportunities exist for its trading strategy. As such, the average number of contracts outstanding in absolute quantities (the total of the open long and open short positions) has been presented as a part of the volume disclosure, as position direction is not an indicative factor in such volume disclosures. All of the Futures Interests owned by the Partnership are held for trading purposes. The monthly average number of futures contracts traded during the years ended December 31, 2020 and 2019 were 3,907 and 6,338, respectively. The monthly average number of metals forward contracts traded during the years ended December 31, 2020 and 2019 were 406 and 650, respectively. The monthly average notional values of currency forward contracts traded during the years ended December 31, 2020 and 2019 were $292,777,322 and $380,666,033, respectively. The following tables summarize the gross and net amounts recognized relating to the assets and liabilities of the Partnership’s derivative instruments and transactions eligible for offset subject to master netting agreements or similar arrangements as of December 31, 2020 and 2019, respectively.

In certain instances, MS&Co. may not post collateral and as such, in the event of default by MS&Co., the Partnership is exposed to the amount shown in the Statements of Financial Condition. In the case of exchange-traded contracts, the Partnership’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 funds may be available in the event of a default. In some instances, the actual collateral received and/or pledged may be more than the amount shown due to overcollateralization.

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. Fair Value Measurements: Partnership’s Fair Value Measurements. The fair value of exchange-traded futures, forward and option 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 foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as input the spot prices, interest rates and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period. U.S. Treasury bills are valued at the last available bid price received from independent pricing services as of the close of the last business day of the reporting period. The Partnership considers 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 and for the years ended December 31, 2020 and 2019, the Partnership 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).

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 partners’ capital of the Partnership.
