Dollar's weakness across the board has pressured price here and the retreat from last Friday's high at 91.33 to retrace recent upmove may extend to 89.90 (previous resistance, now support) and then towards 89.50/60 before prospect of a rebound later.  
On the upside, above 90.95/00 would indicate the rise from this month's low at 88.01 has resumed for a re-test of aforesaid resistance at 91.33 and then 91.60/70.
