Dollar's recent decline has once again resumed in part due to active cross buying in yen and further weakness to 102.60/70 is likely but oversold condition should limit downside to 102.00 and risk has increased for a much-needed correction later.  
Above 103.80/85 would signal temporary low is made and bring retracement to 104.30/40 but 104.95 (previous support) should cap upside.
