I use the Futures + Options report in lieu of the Futures only Commitments of Traders Report. The Futures + Options report is, obviously more comprehensive, and it is also the basis for the COT-Supplemental breakdown of Index Traders. Although the net position patterns may look almost identical for many markets, the actual position totals vary. This brings up an interesting point. In some markets, in some weeks, the totals for the Non-Commercial category may be larger on the Futures Only than on the Futures + Options report:

 How can this be? There can’t be a negative number of option positions open. The explanation is in the 
NON-COMMERCIAL SPREADS category. Large speculators are spreading between futures and options.
If you look at Futures only, it looks like a straight long or short position, but when you include options, the spreads become apparent. I am not interested in the spread number, but I am interested in eliminating spreads from the net positions. This is accomplished by using the Futures + Options (or Index Trader) report.
