Gold edged higher on Wednesday on optimism that Greece's parliament will approve an austerity plan later in the day, underpinning positive sentiment for bullion and other commodities. Light physical buying in Asia also helped support prices, although the volume was seen as insufficient to send spot gold above its recent trading range, dealers said.
Spot gold has traded in a range of $1,490 to $1,506 an ounce this week ahead of the Greek vote and inched up 0.3 percent to $1,505.11 an ounce by 0555 GMT, building on gains from the previous session. COMEX gold was up 0.4 percent to $1,505.90.
