To calculate your profit or loss for a Long trade, please use the following formula:
PL=S*M*(Ec/Eo-1)-C, where:
PL is your profit or loss
S is your investment amount
M is the multiplier/leverage value in use
Ec is the close price
Eo is the open price
C is a commission charged for your trade
To calculate your profit or loss for a Short trade, please use the following formula:
PL=S*M*(1-Ec/Eo)-C
In case your current loss on a trade reaches 50% of your investment amount, your trade is subject to immediate closure. This is to ensure that your maximum risk is limited with your investment amount, i.e., your trade will not affect your funds that are not invested in it.
