Dollar's strong rebound from 89.70 suggests the correction from last week's high at 92.42 has indeed ended there and re-test of this top is seen, break would confirm recent upmove from January's multi-year low at 87.10 has resumed and further headway to 92.90/00 and possibly towards 93.50 would follow.  
Below 91.12 (yesterday's low) would signal temporary top has been formed instead and bring correction to 90.60/70.
