Yesterday's selloff to 91.02 confirms dollar's erratic rise from 88.55 has formed a temporary top last Friday at 92.16 and initial consolidation would be seen today, however, near term over sold condition should keep price above 90.56 and yield strong rebound later but break of said 92.16 high is needed to extend aforesaid upmove to 92.50/55.  
On the downside, below said 90.56 support would yield stronger retracement to 90.00/10 before bounce occurs.
