Euro's rally above 1.4015 in part due to cross buying versus yen suggests the erratic rise from 1.3832 has resumed and above previous resistance at 1.4074 would bring further headway to 1.4100/10 but broad outlook is consolidative and 1.4202 should remain intact.  
On the downside, below 1.3960/70 would prolong choppy trading and yield weakness towards 1.3911 (yesterday's low), however, support at 1.3878 should on hold on first testing.
