Why is there a difference between last trading price and closing price on NSE?

Last traded price (LTP) usually differs from the closing price of the day. Shouldn’t it be same?


The closing price of the day on NSE is the weighted average price of the last 30mins of trading.

Last traded price of the day is the actual last traded price.

Hence the difference. The difference is usually more if the market is moving around quite a bit in the last 30mins.
