Yesterday's rally above previous high 91.09 and subsequent breach of pivotal 92.16 daily resistance to 92.42 suggest erratic upmove from 84.82 (Nov '09) has possibly resumed and further headway to 92.80/90 and then toward 93.78 would be seen next week.  
On the downside, below 91.09 (previous res.) would indicate a temporary top is made and stronger correction to 90.70/80 is likely.
