SAN FRANCISCO (MarketWatch) -- Gold futures fell Friday and oil prices headed lower for a third-straight session as strength in the U.S. dollar helped dull demand for commodities. Gold for February delivery GC2G -0.10% lost $3.60, or 0.2%, at $1,650.90 an ounce on the Comex division of the New York Mercantile Exchange, trading around 1% higher week to date. February crude oil CL2G -2.22% traded at $98.90 a barrel on Nymex, down $1.49, or 1.5%, little changed from a week ago. The dollar index DXY +0.24% traded at 80.247, up from 80.198 late Thursday.
