Hi guys, This is my first reddit post So ignore my mistakes.
I was trading Nifty 5th May 24000 Put in Mstock broker. I bought it at 105 at 11:46:17 and kept triggered SL at trigger price of 82.5 and selling price of 81.
I don't know how but my triggered SL got hit at ₹81 on 11:53:48. And low of 11:53 candle is ₹98. Difference is ₹15.5 from my triggered Sl.
I lost ₹3120 without any reason. Screenshots are added in post.

My question

1. Can I report this to broker or sebi ?
2. If yes, how ? Any other advise are welcome.
