BOS plus Premium price

AUDCAD has been trending bearish for a while, and currently we have lots of liquidities resting below the weekly lows. However, we're currently experiencing a retracement to a supply zone at premium price, my approach is to continue bearish after the inducement of the 4HR OB with a new MSS confirmation on a low TF like 5min or 15min.

Confirmation is important as price could still liquidate the entire structure before the actual move occurs.
