Intraday P/L

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) + current selling volume - current buying volume

Case 1:

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

Current priceQtyPrevious closing pricePrevious closing qtyCurrent selling volumeCurrent buying volume
200 HKD100 shares190 HKD100 shares00

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.

Current priceQtyPrevious closing pricePrevious closing qtyCurrent selling volumeCurrent buying volume
200 HKD100 shares190 HKD100 shares10100 HKD9900 HKD

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.
