USDCAD - Waiting for Signal on H4 to continue to Entry

On this pair - Obviously, it is a downtrend on H4, so I will wait for Signal to short on H4. The question is how and when? As you can see on H4, I light out the Keylevel of Downtrend, when the price come back to this Level we will see how it react to this level and we will decide that the Downtrend will continue or end. I will update later about my Idea when I have clear signal of my setup on USDCAD.
Thanks
