NEW YORK, Oct 20 (Reuters) - U.S. crude futures slipped in choppy trading on Tuesday, but only after reaching a 2009 high above $80 a barrel as the weak dollar supported oil futures and the November crude contract headed to expiration. The November contract approaching expiration could provide some price volatility and some trading sources expressed caution about profit taking, or a correction, after crude's eight consecutive trading days finishing higher. The dollar hit a 14-month low against a basket of currencies on Tuesday as policymakers in Europe and Asia remarked on the dollar slide, but options-related buying kept it from pushing through $1.50 per euro and 90 yen. [USD/] The dollar extended losses against the yen while the euro hovered around a 14-month high after data showed U.S. producer prices fell in September while housing starts rose slightly. "With the dollar at or near multiyear lows against the world's major currencies, investor's may keep looking past oil's fundamentals as long as U.S. interest rates remain close to zero," John Kilduff, senior vice president at MF Global in New York, said in a morning research note.
