Intraday P/L

Intraday P/L refers to the cumulative P/L from the previous trading day’s closing price to the current trading day’s session.

Calculation formula: Intraday P/L = (current price * qty) – (previous closing price * previous closing qty) + current selling volume - current buying volume

Case 1:

Xiaoming holds 100 shares of Alibaba (BABA), and the holdings are as follows.

According to the formula, the intraday P/L is (200 *100) – (190*100) + 0 -0 = 1000 HKD

Intraday P/L: +1000HKD

Case 2:

Xiao Ming holds 100 shares of Alibaba (BABA) at the opening. He first sells 50 shares at the price of 202/share and then buys 50 shares at the price of 198/share. The holdings are as follows.

According to the formula, the intraday P/L is (200 * 100) – (190 * 100) + 202 * 50 – 198 * 50 = 1200 HKD

Intraday P/L: +1200 HKD

Note:

1. The intraday P/L only calculates the actual holdings, excluding transaction-incurred fees such as handling fees.
2. If you liquidate and open a position within the same day, the intraday P/L will continue to be calculated using the data at the time of liquidation.
