March heating oil prices began on a positive note Sunday evening, as they tried to rebound from Friday's downdraft. Some traders suggested that the support might have come from a National Weather Service report that forecasted US heating oil demand to average 7.5% above normal this week compared to 6.5% above normal last week. The Commitments of Traders Futures and Options report as of February 1st showed non-commercial traders were net long 34,225 contracts, an increase of 434. Non-commercial and nonreportable traders combined held a net long position of 56,396 contracts, an increase of 3,261 on the week.
