March heating oil prices opened sharply higher Sunday evening and reached their best level in nine sessions. Prices seemed to come under pressure during the early morning hours, following weakness in crude oil and strength in the US dollar. Some traders indicated that some of the weakness in heating oil prices might have come came from a National Weather Service report that estimated this week's US demand to run more than 26% below normal levels. The Commitments of Traders Futures and Options report as of January 24th showed non-commercial traders were net long 20,148 contracts, a decrease of 339. Non-commercial and non-reportable traders combined held a net long position of 42,783 contracts, for a minor decrease of 383. Prices rallied an additional 1.5% after the COT report window closed, and that might have inspired more long positions.
