November RBOB prices grinded lower during the overnight and early morning hours and challenged 200 day moving average support in the process. Some traders were looking ahead to this morning's EIA inventory report, which is expected to show a decline in refinery output in the Northeast somewhere in the range of 500,000 to 750,000 barrels due to seasonal maintenance. This compares to the five-year average build for this week of the year of more than 2 million barrels.
