Despite yesterday's narrow trade, as long as recent good support area 89.55/60 holds, dollar's corrective upmove from 88.55 to retrace decline from 93.78 should resume after consolidation and further headway to 90.50/55 is likely, however, loss of momentum should cap price below 90.88/90 and yield strong retreat later today or tomorrow.  
On the downside, below 89.80/85 would signal aforesaid rise has possibly formed a temporary top but break of said support area is needed to confirm and bring weakness to 89.15/20.
