Dollar's retreat from 99.77 last Friday due to cross buying in yen suggests the erratic rise from 98.15 has made a top there and consolidation with mild downside bias is seen, however, a breach of 98.51 is needed to signal the decline from 101.45 top has resumed for a re-test of aforesaid support at 98.15 and later towards 97.50.   
Above resistance at 99.77 would bring another corrective rise to 100.00/10 but upside should be capped below resistance at 100.43.
