Despite intra-day retreat from 1.5536, as euro's rebound from 1.5360 suggests recent decline has formed a low last Friday, reckon support at 1.5426 would contain downside and yield another corrective rise for re-test of said resistance, break would extend gain to 1.5570/80.  
Below 1.5426 would indicate the fall from last month's record top at 1.6020 has resumed and yield re-test of aforesaid support at 1.5360.
