4 Hrs: no real sell signal yet, but there is some minor deterioration in current price action, in fact this 4 Hrs move couldn't really get a serious momentum: this is in line with the daily consolidation.
If price can not break above 1,5300, and turns down from here, then it will have a good chance to build a pattern as well.
Real sell signal would come in with a real break and with a follow through below 1,5200.
We can either wait, or maybe start to "gamble" a bit on this chart now. I'd sell some small here, with stop above 1,5300. Size up below 1,5200. Let's put this EURCAD on the radar, as it can become interesting soon again.
