In both(NF & BNF) short trade triggered below Yesterday LOD and according to me there was no problem to enter or take that short trade. there was sufficient time to take that trade.

I cannot say anything on this. Because it would be unfair to comment on your system.
personally I would never take a short trade for the reason that it came below previous day low.
Some methods like these will work in trending days and Some other methods which buy near previous low as a support will work in narrow ranging days. Right ?
My view here is just that it is not a valid method to analyze an outcome after the event happened.
