Despite yesterday's initial brief drop to 90.07 (our daily position entered long at 90.10), subsequent strong rebound n breach of Monday's 90.94 high signals upmove from last week's 89.14 low has resumed and further headway to 91.50/60 is envisaged but reckon resistance at 91.80/90 should cap upside.  
On the downside, below 90.40/50 would suggest a temporary top has possibly been formed and yield re-test of said yesterday's 90.07 low first.
