The fall from 5340 clearly shows 5 wave pattern, and the last 3 days swings suggests the 5th wave is extending and forming ending diagnol pattern. To confirm this we are in 5th wave, +ve divergence has been shown in the RSI.
So next week there could be another 30 to 50 points fall (to complete wave 'v' of wave '5') and take a reversal and move to the range of Wave '4' i.e 5100 range.
Incase if NIFTY falls below 4850 (then ending diagnol consideration might be out), bcs wave 'iii' cant be shortest. So Nifty has to recover before 4850 to expect relief rally in NIFTY.
