SINGAPORE, Sept 23 (Reuters) - Gold extended gains on Wednesday, moving closer to an 18-month high struck last week, after the U.S. dollar tumbled to its weakest in a year against the euro, but worries about heavy liquidation persisted.
The rise has stoked fears of a repeat of last year's selling, when bullion lost more than $100 only a few days after it powered to a record $1,030.80 an ounce in March. Gold has gone up as much as 16 percent this year.
Some investors were also reluctant to buy heavily before the U.S. Federal Reserve announces the outcome of its two-day meeting later in the day, although markets believe the Fed will signal plans to maintain loose monetary policy well into 2010.
Spot gold <XAU=> hit an intraday high of $1,017.80 before slipping to $1,013.95 an ounce by 0233 GMT, still steady from New York's notional close and within striking distance of an 18-month high of $1,023.85 hit on Thursday.
"At these levels here, obviously they need a further catalyst to get an upside. At the moment, the market will be coy on the basis that we've got now record high long positions on the CFTC," said Mark Pervan, senior commodities strategist for ANZ.
"The market is quite concerned there could be some unwinding of those positions. If they really unwound heavily, I think we'll go back to $950 very quickly. I suspect there's a pretty strong floor at $995," said Pervan, referring to this week's 1-week low.

"We have to watch to the dollar because if it goes up again, then it wil attract some selling in gold. We are also watching the G20 meeting and its impact on the dollar," said a dealer in Hong Kong. "But at the moment, I we don't even see demand from the physical side," he said.
