Consider price is in the downtrend- LL, LH formation creating IMPULSIVE MOVE. Mostly corrective move have 3 upside failed pushes and another BoS on downside and failing to retest creates "pinbar" and price extend further downside breaking 3 candle retracement. After that any pullback into an OB i.e. failed retest could be a potential opportunity.
(1st) Failed to make HH-HL (2nd)BoS of Structural range (deep pull back) (3rd) BoS of 3 candle retracement (Pin bar formation) (4th) Pull back into OB will be an entry point.
