Spot gold <XAU=> was at $758.80/759.60 an ounce as of 0308 GMT, little changed from $759.20/760.00 late in New York. Platinum <XPT=> fell to $1,436/1,441 an ounce from $1,445/1,449 late in New York.

Gold gained more than $6 on Tuesday as a sharply weaker dollar prompted bargain hunting and continuing geopolitical tension in the Middle East also helped draw money into bullion.

"It is the dollar which now sets the tone of the gold market," said Tatsuo Kageyama, analyst at Kanetsu Asset Management Co Ltd. "The next Federal Reserve meeting is due later this month, and prior to that, the dollar is pausing, and so is gold," he said.

U.S. existing home sales data later in the day and new homes sales data on Thursday will be carefully watched before the Fed meeting, where the U.S. central bank is expected to cut interest rates.

Technically, gold's resistance was pegged at last week's 28-year high of $770, while support was seen at $750.
