Dollar's rebound after yesterday's cross-inspired selloff to 87.36 (European morning low) suggests the decline from 90.78 has formed a temporary low there and consolidation with mild upside bias is seen for a corrective rose to 88.70/80 before prospect of another fall later.  
On the downside, below 87.36 would bring retracement of recent upmove from 84.82 (last month's low) to 86.90/00 and then 86.50 before rebound.
