Why does the P&L on holdings and positions page on Kite change post 3.30 PM?

The P&L on the holdings and positions page on Kite changes after 3.30 PM due to the difference between the Last Traded Price (LTP) and the closing price.

Equity P&L on Holdings page

During trading hours (9:15 AM to 3:30 PM), the LTP or live price is used to calculate the P&L for stocks on the holdings and positions page. However, after the market closes (post 3.30 PM), the exchange declares the closing price, which is the weighted average of the last 30 minutes of trading (between 3:00 PM to 3:30 PM). The holdings page then uses this closing price to calculate the value and P&L for stocks.

F&O P&L on Positions page

For futures and options (F&O), the calculation of P&L also depends on the time it is viewed:

• Between 9:15 AM to 3:30 PM, the LTP is used.
• Between 3:30 PM to midnight, the LTP at 3:30 PM is used.
• From the next day until 9:15 AM or market opening, the previous day's closing price is used.

Since the last traded price and closing price can differ, the P&L shown on the holdings and positions page may vary accordingly.
