Why is the option contract or option chain LTP on Kite different from NSE?

The option contract or option chain LTP on Kite may differ from NSE because the option is illiquid. For illiquid contracts, if there are no trades in the last 30 minutes of the trading session, NSE will provide a theoretical settlement price. The Settlement Price is updated in place of LTP on Kite the next day when Zerodha receives a report from NSE called BHAVCOPY.
