The position size calculator is an important risk management tool. To use the calculator, choose your account's currency and type in your account's balance. If you want to risk a certain percentage of your account size, type this percentage in. Alternatively, click the swap icon and enter the amount of cash you wish to risk. Finally, type in the trade's stop loss in pips, select the currency pair you're trading and click the Calculate button.
