Euro's anticipated rebound from yesterday's low at 1.2780 suggests decline from last Friday's high of 1.3334 has possibly made a minor low there and gain towards 1.2933 cannot be ruled out but reckon 1.2951/55 would cap upside and yield retreat later.  
On the downside, below 1.2822 would signal aforesaid decline has resumed again for re-test of 1.2780, then 1.2732.
