Pure Bearish form of Nifty

Here I am mentioning 3 possibilities for Nifty 50.
Scenario 1: if Nifty breaks down to 16400 - 16300 to reverse, then it is an Inverse Head and Shoulders.
Scenario 2: Nifty May drop to 15500 around to form a double bottom on weekly and then reverse.
Scenario 3: This is worst of all, if nifty drops to 14200 then it confirms a Megaphone pattern.

Overall Nifty is in the corrective territory.
