Dollar's sharp retreat from 90.80 NY high and intra-day breach of 90.30 just ahead of Tokyo opening confirm recent upmove from 88.14 has indeed formed a temporary top Friday at 91.09 and consolidation with downside bias is seen for a retracement to 90.00 and then 89.80/85, however, reckon 89.60/65 would contain weakness today.  
  
On the upside, above 90.55/60 would bring rebound to 90.80/90 but only break of said 91.09 high would yield one more rise to 91.45/50.
