Dollar's rally above previous res at 104.04 (now sup) confirms the correction from previous high at 105.70, although strong, has ended earlier at 102.57 and near term upside bias is seen for gain above said yesterday's top, a breach of pivotal res at 105.59 is needed to signal the 'erratic' rise from 08' low at 95.77 has once again resumed and yield further headway towards 106.07 later.  
In the event dollar drops below aforesaid sup at 104.04, then this would abort intra-day bullish scenario and risk would shift to the downside for a stronger retracement back towards good sup area at 103.27/39.
