Despite Friday's resumption of rise to 91.09, dollar's sharp retreat to 90.30 (NY) suggests recent erratic upmove from 88.14 has possibly formed a temporary top there and consolidation with downside bias is seen for a retracement to 90.10/15, below would bring further weakness to 89.83 but reckon 89.60/65 would hold and bring rebound.  
On the upside, above said 91.09 temporary high would extend gain marginally to 91.25/30 before correction occurs due to loss of momentum.
