The sharp last-minute spike is from SEBI’s new Closing Auction Session (CAS) that started today for F&O stocks. Continuous trading stopped at 3:15 PM with Nifty near 24,590. The auction then matched orders until ~3:35 PM and set the official close at 24,774.30. That vertical green candle is pure auction price discovery, not normal continuous trading.
