Why does the Last traded price(LTP) for F&O contracts change in the Kite position page before the market opens?
The Last traded price(LTP) value for F&O contracts changes to the settlement price before the market opens as the settlement price is updated in place of LTP once Zerodha receives the BHAVCOPY from NSE, which happens between 6:30 AM and 7:00 AM the next day.
LTP of the day is the actual last traded price, whereas the closing price of the day on NSE is the weighted average price of the last 30 minutes of trading. The closing price and settlement price will remain the same for liquid contracts. For illiquid contracts, if trades have not taken place in the last 30 minutes, the exchange will provide a theoretical settlement price which will be shown in place of the LTP.
