NEW YORK (MarketWatch) -- Gold futures edged higher early Thursday, extending their gains from the previous session, as the U.S. dollar traded mixed against other major currencies. Gold for February delivery gained $3.50 to $872 an ounce on the New York Mercantile Exchange. The dollar was mixed against major counterparts, but sentiment remained fragile in the wake of the greenback's pounding by the euro and other currencies after the Federal Reserve announced historic efforts this week to revive the U.S. economy.
