Dollar's rally to 104.66 on Friday in line with the greenback's broad-based rise and also active cross selling in yen suggests recent upmove may extend towards 105.00 but anticipated overbought condition has increased risk of a correction later.  
On the downside, below 103.60/65 would signal a temporary top has been formed instead and yield retracement to 102.95 (previous resistance, now support).
