Oil futures fell on Friday, with U.S. prices pulling back to end a nine-session stretch of gains that was the longest since January 2010.

February West Texas Intermediate oil fell $1, or 1.9%, to settle at $51.59 a barrel on the New York Mercantile Exchange.

After finding support throughout the week from data showing output declines among major oil producers, a weekly fall in U.S. crude inventories and optimism surrounding a possible resolution to the U.S.-China trade dispute, WTI crude ended 7.6% higher for the week.
