NEW YORK (MarketWatch) -- The U.S. dollar remained higher versus other major currencies on Tuesday after a report from Case-Schiller showed home prices rose 1.6% in July from the previous month. The dollar index (DXY 77.22, +0.17, +0.22%) , a measure of the greenback against a trade-weighted basket of currencies, rose to 77.153 from 76.904 on Monday. Still to come is a report that is expected to show an improvement in consumer confidence.
