The rally from ~7950 to ~8950 has taken 50 bars / 75 days and the fall from ~8,950 to ~8,000 is in equal time cycle. Relative Strength Index is trading at 2016 lows suggesting reversal on cards. I am expecting the reversal to take place either today or tomorrow. The setup would fail if Nifty closes below 7,900. The major trend change level would be only above 8,600.
