Trading sentiments at futures market were dampened after crude oil prices retreated in Asian trade today on profit-taking following a six-day rally, with rise in OPEC's output in March also adding to downward pressure, analysts said.
Meanwhile, West Texas Intermediate crude for May delivery eased by 43 cents to USD 56.28, while Brent crude for June fell 48 cents to USD 63.50 a barrel in late-morning trade on the New York Mercantile Exchange.
