The performance of dollar during Thursday trades was very mixed: it gained versus the yen, but at the end of the day came out with little gaining against the euro, because the stocks went up in the morning trades and then stalled during trading in the afternoon.
Risk-sensitive currencies were more popular on Thursday, therefore, the pound of sterling and the Canadian dollar both gained against the American dollar. Due to May Day holiday in many European countries, on Thursday the market was expecting weak trades on Friday, therefore having comparatively directionless trading session.
