How this is calculated

Risk amount = balance × risk percent ÷ 100, or the fixed amount you enter.

Position units = risk amount ÷ (stop distance in pips × pip size × quote-to-account rate). Divide by units per lot to obtain lots, then round down to your permitted lot step and recalculate the modeled risk.

Fees, slippage, gaps and changing rates are not included. Actual losses can exceed this calculated amount.
