LONDON (Reuters) - Gold prices fell on Tuesday after a reading of U.S. service-sector business activity came in stronger than expected, lifting the dollar, while the euro retreated ahead of a European Central Bank meeting later this week.
Investors are closely watching U.S. data for clues on when the Federal Reserve will taper its quantitative easing programme, a major driver of higher gold prices during the financial crisis.
Spot gold was down 0.4 percent at $1,308.64 an ounce at 1525 GMT, while U.S. gold futures for December delivery were down $6.00 an ounce at $1,308.70.
"We've seen some quite good economic data out of the U.S., which has led to a rise in the dollar and has weighed on commodity prices, gold especially," Commerzbank analyst Daniel Briesemann said.
"In addition, the ECB meeting is imminent on Thursday. After the very low inflation rate published for October, there are already rumours in the market that the ECB is going to lower interest rates," he added. "These expectations are also helping the dollar gain ground, and weighing on gold."

ASIAN GOLD DEMAND LANGUISHES
Gold demand in major consumer India failed to pick up on Tuesday after a soft week. Consumers bought little gold during Diwali, the Hindu festival of lights, over the weekend, although it is usually a popular occasion for bullion purchases.
Indian gold premiums have halved from last week, traders said, as demand for the metal dropped after festival season.
Premiums in China, which is poised to take over from India as the world's biggest gold consumer, recovered slightly this week but have not seen a big jump.
Among other precious metals, silver was down 0.2 percent at $21.62 an ounce.
