The euro is holding over 121.73 yens per euro, leaving a double floor on the four hours chart. If it loses it, it will open the door towards 120.5. In the way, we highlight 121.07 as a possible rebound zone. Yet, the double floor could be a good place for the euro to rebound. The first step is at yesterday's high. Clearing it would break the last lower high. That is, a possible trend shift.
