Although euro has penetrated yesterday's high at 1.4277 and the rise from this week's low at 1.4045 to retrace decline from '09 top at 1.4448 has resumed, loss of momentum should cap price at previous resistance at 1.4328 and yield retreat later.  
Below 1.4200/09 would indicate a temporary top is formed and correction of aforesaid rise towards 1.4140 would follow.
