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. Futures and forwards 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 gain or loss on open futures or forward contracts. The resulting net change in unrealized gains and losses is reflected in the “Net change in unrealized gains (losses) on open contracts” in the Statements of Income and Expenses. The Partnership’s 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-traded non-exchange-traded 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 non-exchange-traded non-exchange-traded 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 futures, forward and option positions by sector, margin requirements, gain and loss transactions and collateral positions. The futures and forwards traded by the Partnership, along with 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 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.

Trading Activities	5. Trading Activities: The Partnership’s objective is to profit from speculative trading in Futures Interests. Therefore, each Trading Advisor for the Partnership will take speculative positions in Futures Interests where it feels the best profit opportunities exist for its trading strategies. 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 three months ended June 30, 2020 and 2019 were 2,164 and 3,078, respectively. The monthly average number of futures contracts traded during the six months ended June 30, 2020 and 2019 were 2,117 and 2,902, respectively. The monthly average number of metal forward contracts traded during the three months ended June 30, 2020 and 2019 were 283 and 354, respectively. The monthly average number of metal forward contracts traded during the six months ended June 30, 2020 and 2019 were 340 and 370, respectively. The monthly average notional value of currency forward contracts traded during the three months ended June 30, 2020 and 2019 were $51,605,809 and $87,358,805, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. Fair Value Measurements: Fair value is defined as the value that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. 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 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).
