Although dollar has risen after finding renewed buying interest at 89.88 in Asian morning yesterday, the upside has capped at previous strong resistance at 90.56 and subsequent selloff suggests further weakness to 89.20/30 would be seen before another rebound takes place later today.  
  
Above 90.00/10 would bring re-test of said resistance, however, only a firm break there would yield stronger retracement of recent decline from 93.78 to 90.85/90.
