Yesterday's breach of 89.18/29 in line with the dollar's broad-based weakness signals the erratic decline from 82.33 has resumed and below 88.75 (overnight New York low) would bring re-test of daily support at 88.01 but anticipated oversold condition should prevent steep fall and yield corrective rebound later.  
On the upside, above resistance at 89.72/74 would indicate a temporary low has been formed and risk rebound to 90.00.
