Related Party Transactions [Abstract]
Related Party Transactions	2. Related Party Transactions The cash held by each Trading Company is on deposit with MSSB, MS&Co., and MSIP in futures interest trading accounts to meet margin requirements as needed. MSSB pays each Trading Company at each month end interest income on 100% of its average daily funds held at MSSB. Assets deposited with MS&Co. and MSIP as margin are credited with interest income at a rate approximately equivalent to what MS&Co. and MSIP pay or charge other customers on such assets deposited as margin. Assets not deposited as margin with MS&Co. and MSIP are credited with interest income at a rate equal to the monthly average of the 4-week U.S. Treasury bill discount rate less 0.15% during such month but in no event less than zero. For purposes of such interest payments, net assets do not include monies owed to each Trading Company on Futures Interests. MSSB and MS&Co. will retain any excess interest not paid to each Trading Company. The Partnership pays monthly administrative fees and general partner fees to Ceres. The Partnership pays to MSSB ongoing placement agent fees on a monthly basis equal to a percentage of the net asset value of a limited partners' Units as of the beginning of each month.
