Euro's retreat from 1.4328 suggests the rise from this Wednesday's low at 1.4086 has formed a temporary top and consolidation with mild downside bias is seen for weakness towards 1.4180/85, however, pivotal support at 1.4123 should hold from here and yield a rebound later.  
On the upside, only above aforesaid resistance at 1.4328 would signal stronger correction of recent decline from 2009 high at 1.4448 is under way and extend gain to 1.4370/80.
