Dollar's upmove from 87.36 has resumed yesterday in part due to cross selling in yen and further headway towards 90.20/30 is envisaged, however, broad outlook remains consolidative and reckon previous resistance at 90.78 would hold on first testing, yield retreat later.  
On the downside, below yesterday's low at 89.39 would signal a temporary top has possibly been formed but breach of 89.00 (previous resistance, now support) is needed to confirm.
