Yesterday's cross-inspired selloff to 89.92 confirm erratic upmove from 88.55 has indeed formed a top last Friday at 92.16 and intra-day downside bias remains for further weakness to 89.65/70, however, near term over-sold condition should prevent steep fall below 89.10/20 and risk has increased for a strong rebound to take place.  
On the upside, above 90.55/60 would bring gain to 90.95/00 but only break of 91.10/20 would signal a temporary low is made.
