Jsw energy insider activity

I have a doubt that there was a insider activity on 27th October (Buy value more than sell value) But Delivery not showing anything. 28th October script went to ASM category.
Could any one explain

  1. Why there is no delivery details mentioned?
  2. Why same person/Trust sold & bought with bigger value?
  3. Logic behind this entire scenario?
  4. Do we need to consider in this situation to enter into the trade for swing trade(Not investment) or look back a step & watch?

Script is now at Demand Zone & also corrected 17% from all time high.
