Yesterday's strong rebound from 89.76 and subsequent marginal gain above Friday's high to 90.94 confirm dollar's recent decline from 93.78 has indeed formed a temporary low earlier at 89.14 and retracement to 91.50/55 is likely, however, reckon 91.90/92.10 resistance area should cap upside and bring retreat later.  
Below 90.50 would suggest aforesaid correction is possibly over but break of said 89.76 sup is needed to confirm and yield subsequent weakness to 89.50/55.
