Related Party Transactions [Abstract]
Related Party Transactions	3. Related Party Transactions The Partnership's cash is on deposit with MSSB and MS&Co. in Futures Interest trading accounts to meet margin requirements as needed. At each month end, MSSB pays the Partnership interest income on 80% of the funds on deposit with the commodity broker at a rate equal to the monthly average of the 4-week U.S. Treasury bill discount rate during such month. MSSB retains any interest earned in excess of the interest paid by MSSB to the Partnership. For purposes of such interest payments, net assets do not include monies owed to the Partnership on Futures Interests. The Partnership pays brokerage fees to MS&Co.
