"It has been a tremedously unusual run for the dollar. You will have to go back to pre-euro [days] to find this kind of concentrated move basically over a week-and-a-half. So you can expect some consolidation," said Joseph Trevisani, chief market analyst at FX Solutions in Saddle River, New Jersey.
"When I looked at the charts ... those gradual declines which kept going hour after hour were new positions being established. Some of them were shorter-term and some of those have taken profits. I am sure those positions will be shorted again if you get euro above 1.48 [against the dollar]," Trevisani said.
