EURAUD had a 120 pips spike on H1 CS, so usually when this kind of phenomenon happens, there'll be a relatively strong pull back either partial of CS or an entire pull back to the resistance where it broke through to test as a new support.
However, I'll be looking for a buy opportunity in the box, if it bounces at that area for a double bottom on H1 chart.
Not really fond with EUR fundamentals, so this is entirely based off technical only. Trade safe :)
