Although dollar's retreat from yesterday's multi-month high at 101.45 suggests temporary top has been formed, as price action from there is viewed as a correction of recent upmove, reckon 100.00/10 would limit downside and yield rebound later, however, only above 101.45 would confirm uptrend has once again resumed.  
  
Below support at 99.90 (yesterday's Australian low) would bring a stronger retracement towards 99.33 before prospect of another rise.
