How it works
The risk amount is your balance times the risk percentage. The lot size is that amount divided by the stop loss in pips times the value of one pip for one lot.
The lot size is rounded down to 0.01, because rounding up would risk more than you chose. The result shows the actual risk at the rounded size.
Good to know
- The pip value depends on the pair and your account currency: about 10 for EUR/USD on a USD account, different for JPY pairs and crosses. Check it in your platform.
- Risk per trade is a choice you make in advance. Many traders keep it small so that a run of losses cannot end the account.
- Spread, commission and slippage are not included: the real loss on a stopped trade can be a little larger.
