* Gold falls on charts, awaits Fed, U.S. Q1 GDP data * Platinum bounces after hitting 1-month low * ETF gold holdings unchanged By Lewa Pardomuan SINGAPORE, April 29 (Reuters) - Gold extended losses on Wednesday after its failure to break above recent highs around $918 spurred more technical selling, with investors also unwinding positions ahead of a Federal Reserve meeting and U.S. GDP data. The Fed is expected to leave interest rates unchanged, but markets will be looking for any extension of quantitative easing and for assessments for any early signs of a recovery in the United States. Spot gold was quoted at $890.80 an ounce, down $0.30 from New York's notional close on Tuesday, when it posted its biggest daily percentage drop in almost two weeks. "There's some stop-loss selling. You can say we are slightly bearish on gold because it's below $900," said Ronald Leung, director of Lee Cheong Gold Dealers in Hong Kong. Gold rallied to a near four-week high of $918.25 on Monday as equity markets fell, due partly to fears a swine flu outbreak could hurt the economy, and hopes China could buy more gold to boost reserves. But a failure to breach that level, weak oil prices and a firm dollar against the euro prompted speculators to lock in profits and triggered technical selling. Trading was thin in Asia, with Japanese speculators away for a local holiday. "After we moved back down the $900s, I am neutral on gold now. Seems like we are going to be in a range trade. I still think that the equity markets and the global economy is the factor to look at," said a dealer in Singapore. "I think we got to look out for a couple of things today, including the FOMC meeting and US advance Q1 GDP. I am hearing a lot of news about the swine flu but I am not very convinced the the markets are very much focused on this yet. Commodities investors have been spooked by fears of a swine flu pandemic, with new infections found around the world on Tuesday as governments warned people to stay away from Mexico where 149 people have died.

Platinum , used as an autocatalyst, was up $6.50 at $1,094 an ounce after falling as low as $1,066.50 on Tuesday, its weakest since March 19, to track declines in equities markets and as worries about demand from automakers resurfaced.
