Dollar's present rebound from intra-day low at 104.92 (Australia) suggests the strong pullback from last week's high at 105.88 has possibly ended there and abv 105.74 would signal recent erratic upmove has once again resumed, yield subsequent headway to 106.00/10, however, loss of momentum should limit upside to 106.20/30 and risk has increased for a strong retreat.  
Only a firm break below aforesaid support at 103.92 would abort present bullish view and may risk stronger correction to 104.35/40.
