Oct 16 (Reuters) - Gold steadied as the dollar eased on Friday but was still set for its first weekly loss in three as doubts grew over a U.S. stimulus agreement before next month's presidential election.
Spot gold XAU= was up 0.1% at $1,908.72 per ounce by 1204 GMT but down more than 1% so far this week. U.S. gold futures GCcv1 gained 0.2% to $1,913.30.
"The lack of any physical stimulus now until post the U.S. election perhaps saw some liquidation of gold this week," said Robin Bhar, an independent analyst.
"Gold is pretty much watching what other markets are doing, it doesn't really have too much of a catalyst itself to move significantly higher, and equally not much of a catalyst to move significantly lower."
