Gold may decline in London as some investors sell the metal after its rally to a record Tuesday and amid concern prices might fall if US lawmakers agree to raise the nation\'s debt ceiling. Gold\'s 14-day relative strength index, a gauge of whether a commodity is overbought, on Monday rose to 69.5 and prices reached $1,624.07 an ounce as lawmakers remained deadlocked on how to tackle the US debt crisis and avert a default before an August 2 deadline. Some analysts who study charts view a reading above 70 as a signal that prices may be set to drop. \"The metal is currently trading close to the overbought region,\" UBS AG analyst Edel Tully said in an emailed report yesterday. \"We expect a correction in the near term.\" Immediate-delivery bullion fell $2.75, or 0.2 per cent, to $1,611.40 an ounce by 11:47am in London. Gold for December delivery was little changed at $1,614 on the Comex in New York.

Net-long positions, or bets prices will rise, rose 11 per cent, from a week earlier.
