Dollar's retreat on Friday after being capped below 94.47 suggests recent erratic upmove from 87.10 has possibly formed a temporary top there last week and consolidation with downside bias is seen for another corrective fall, a breach of 92.51 support (Friday's low) would encourage for further weakness towards 91.70/80.  
On the upside, above 94.00 would indicate pullback has ended and risk possible re-test of aforesaid resistance at 94.47.
