How do I calculate my transaction's profit or loss?

To calculate your profit or loss for a Long trade, please use the following formula:

PL = S * L * ( Ec / Eo – 1 ) – C , where:

PL is your profit or loss

S is your investment amount

L is the leverage value used

Ec is the close price

Eo is the open price

C is commission charged for your transaction

To calculate your profit or loss for a Short trade, please use the following formula:

PL = S * M * ( 1- Ec / EO) – C

Let's assume you open a long Dow Jones trade worth $1,000 at 15,345 with leverage set at 10 and close it at 15,515. Your transaction fee is $1.70, and the rollover fee is -$3.80.

So we get: 1,000 * 10 * ( 15,515 / 15,345 – 1) – 1.70 – 3.80 = $105.28.

Your transaction profit is $105.28.

Now let's assume we open an identical short trade:

1,000 * 10 * (1 – 15,515 / 15,345) – 1.70 – 0.20 = -$112.68

Here, your loss would be $112.68.
