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).

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.

Financial Instrument Risks

Investments, All Other Investments [Abstract]
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. Forward Foreign Currency Contracts. London Metals Exchange Forward Contracts. 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. For certain OTC contracts traded by Cambridge Master and SECOR Master prior to their respective full redemptions, JPMorgan was the counterparty with respect to those 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/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 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.
