I have tested this approached for all NIFTY 50 stocks/FINNIFTY/ BANKNIFTY .
NIFTY Current Position long , bought on March 19 at 14628 . Action for 23 rd March, Continue Long and reverse to SHORT if NIFTY closes below 14671.22
Profit from this trade as of today is 115 Points
Profit from last trade (SELL) : 483 Points.
Please note this number ( 14671.22 ) is a SWING number and it means if NIFTY closes (LTP @ 15:30) below this number there is a good possibility (76% chance ) of moving in down direction next trading day.This number may come in intraday or at EOD .The price needs to be stable/traded below this number and also close below this number (both conditions ) to carry a SHORT position.
Nifty Trend Change timings for March 22 2021 : 10:13,10:55,12:18,12:48,13:52,15:04. 12:48 is KEY timings
