Although euro has rebounded after yesterday's retreat to 1.3492 and consolidation with mild upside bias is seen, a break above 1.3640/53 resistance area is needed to signal correction from last week's high at 1.3739 has indeed ended at 1.3418 and yield resumption of recent upmove for re-test of said top later.  
On the downside, below aforesaid support at 1.3492 would prolong choppy trading and risk weakness to 1.3440/50.
