Kite's historical API in python is not returning any ticks for Nifty50 stocks after 15:15 from 3 Aug 2026 onwards. It works fine for older days and for indices in Aug 2026. I suppose this is due to the new CAS rules. Does this mean that from here on, F&O segment stocks will have ticks data only till 15:15?
Index and Stock F&O contracts trade until 3:40 PM, while stocks under the Closing Auction Session (CAS) have continuous trading until 3:15 PM. Accordingly, F&O historical data is available until 3:40 PM, while CAS stock data is available until 3:15 PM. You may refer this.
