Yesterday's rally above 1.4013 (now support) is line with the greenback's selloff versus other European currencies signals the decline from this month's top at 1.4339 has indeed ended earlier at 1.3748 and upside bias is seen for further gain to resistance at 1.4178, however, loss of momentum has increased risk of a correction.  
On the downside, only below 1.4013 would indicate a temporary top has been formed and yield retracement to 1.3950/60.
