EURCAD possible short

Potential short opportunity from this supply zone on EURCAD if price were to pullback and fulfil the imbalance it has left behind. We are in an overall downtrend on the hourly timeframe, so for me, I'm on the lookout for selling opportunities. I like this supply zone because it has created a break of market structure to the downside which tells me it is a strong high which institutions may fight to hold. If price does retrace and mitigate said supply zone, I myself will be awaiting a further confirmation before entering a sell position to the low of the leg.
