Yesterday's sharp retreat after rebounding strongly from 90.02 to 90.72 suggests further volatile choppy trading inside near term established range of 89.97-90.74 would continue, however, as long as said upper resistance level holds, downside bias remains for weakness to 89.80/85 but reckon 89.55/60 should hold.  
On the upside, only above 90.74 would suggest pullback from Friday's 91.09 high has indeed ended earlier at 89.97 and yield subsequent re-test of said high first, break extends gain to 91.45/50.
