Thank you for putting this to us directly, and questions like this deserve a straight answer.
Indian exchanges don’t tag which side initiated a trade. Every platform building order flow here, including us, works out the aggressor side from tick data rather than reading it directly off the tape the way you could on a market like CME. We explained exactly how that works, and why two platforms can show a different delta on the same candle without either one being wrong, in this post. Please go through it, and if anything’s still unclear, happy to clarify.
On why that video draws the conclusion it does, we’re not going to guess at anyone’s reasoning. That’s not a conversation we can have honestly from outside their head.
