Yesterday's rally above 90.04 (previous resistance, now support) in line with the greenback's rise across the board suggests price would continue gyrate inside the range of 89.18-91.34 and upside bias is seen for gain towards 90.90/00, however, reckon 91.34 should on first testing and yield retreat later.  
On the downside, only below 89.64 (yesterday's low in Asian session) would risk weakness towards support area at 89.18/29.
