Retracement from 13967-13864 is not even 23% of wave iii that is why there is a point of confusion if wave v is started from 13864 OR wave iv decline is still pending.
Overall scenario:
(1) If nifty decline from here then 13847-13722 is support range and 13722 is trend reversal point. (2) If wave iv is completed at 13864 then 14184-14381 is wave v projection range.
