November heating oil prices continued to grind lower during the early morning hours, falling to their lowest level since August 9th. It appears that fresh Greek debt concerns, rally in the US dollar and weakness in Brent crude oil have weighed on the market. The Commitments of Traders Futures and Options report as of September 27th showed non-commercial traders were net long 7,758 contracts, a decrease of 13,456. Non-commercial and nonreportable traders combined held a net long position of 14,111 contracts, for a decrease of 18,942 on week. This represents more than a 50% reduction in the net spec long positioning in just one week.
