AUDCAD Buying the retracement

AUDCAD is on a bearish trend on HTF but currently on a retracment. Giving us HH and HL which makes it bullish on the smaller TF

Price retracing to the LQ found @0.88664.
Im looking at it grabbing that and moving down to the OB below before buying up.

Looking at entry @0.88583
We wait to see market reaction on that block.
