The greenback tumbled to 88.23 in thin Australian morning yesterday and then rebounded to 90.20 high today, suggesting recent decline has possibly formed a temporary low there and consolidation with mild upside bias would be seen, however, as long as 90.35/47 (previous supports) holds, a retreat to 89.15 is still likely but break needed to confirm recovery is over and yield resumption of decline for re-test of said low.  
  
On the upside, above 90.47 may bring stronger retracement, however, 91.59/63 resistance area is expected to remain intact...
