During Friday's session, the API estimated that August U.S. gasoline demand was down 0.8% from year ago levels. That coupled with weak U.S. Consumer Sentiment data seemed to pressure November RBOB lower throughout the session. However, this morning outside markets seem to foster a slight pro-risk taking sentiment that was apparently helped by a jump in global equity markets and a slumping U.S. Dollar overnight. The Commitments of Traders Futures and Options report as of September 14th for gasoline (RBOB) showed non-commercial traders were net long 32,179 contracts, an increase of 9,375. Non-commercial and nonreportable traders combined held a net long position of 29,479 contracts. This represents an increase of 12,188 contracts in the net long position held by these traders. Prices fell an extra $0.05 since that report window, and that suggests that the latest data could be overstated.

Lot's and lot's of spec longs in all these commodity markets.
