NEW YORK (MarketWatch) -- Treasury prices gave up small gains and the dollar remained under heavy pressure on Tuesday after the Institute for Supply Management's non-manufacturing index climbed to 53.2 in September from 51.5 in August, a higher reading that some analysts had forecast. The dollar index (DXY 77.96, -0.49, -0.62%) , a measure of the greenback against a basket of six major currencies, slipped to 77.992 from 78.442 in late North American trading on Monday. The euro rose to $1.3792, after rising to its highest level in more than six months, up from $1.3686 Friday. Yields on 10-year notes (UST10Y 2.47, -0.01, -0.44%) , which move inversely to prices, fell 1 basis point to 2.47%, after declining to 2.43% in early trading.
