Hi Hiren,
As per my understanding from the same video,-
Scenario-A
If Pros want to go LONG in the mkt-
1.They Sell PUT & don’t buy CALL if “IV is HIGH”
2. They Buy CALL & don’t Sell PUT if “IV is LOW”
in both of the above positions they are BULLISH in the mkt.
Scenario B
If pros want to go SHORT
1) They Buy PUT & don’t Sale CALL, if “IV is HIGH”
2) The Sale Call & don’t buy PUT, if IV is LOW”
in both of the above position they are BEARISH in the mkt.
Hope I am able to clarify this,if it is a wrong interpretation by me The OCEAN of Knowledge-Nitin Sir to kindly correct.
