September heating oil prices took on a slightly lower track during the initial morning hours, perhaps in an attempt to correct Friday's upside breakout action. However, some traders were concerned over the relatively average trading volume that came with the upside breakout in prices. The Commitments of Traders Futures and Options report as of July 31st showed non-commercial traders were net long 900 contracts, a decrease of 116. Non-commercial and nonreportable traders combined held a net long position of 8,735 contracts, for an increase of 1,927 in the net long position held by these traders.
