Dollar's rally to 90.78 in line with the greenback's rise across the board in New York session (following the release of the stronger-than-expected U.S. employment data) signals the upmove from last month's low at 84.82 has resumed and further headway to 91.00/10 before prospect of a pullback.  
On the downside, below 89.40/50 would signal a temporary top has been formed instead and risk correction to 88.90/00.
