Despite the recovery fm 88.59 (Tuesday's low), broad outlook is consolidative and further choppy trading below 90.79 is seen with downside bias, yield another fall to aforesaid sup and break there would bring correction of recent upmove from 87.10 low towards 87.90/00 later.  
Above resistance at 90.00 would shift risk to the upside for gain to 90.30/40 but reckon 90.79 would hold on first testing and bring retreat.
