How to Use This Calculator
- Account Balance: Your total trading capital in euros. This is the amount you have available to trade with.
- Risk per Trade: The percentage of your account you’re willing to risk on this single trade. Most professional traders risk between 1-3% per trade.
- Entry Price: The price at which you plan to enter the trade (buy or short).
- Stop Loss Price: The price at which you’ll exit the trade to limit your loss. Set this below entry for long trades, above entry for short trades.
The Formula
Risk Amount = Account Balance × Risk %
Position Size = Risk Amount ÷ |Entry Price − Stop Loss Price|
Position Value = Position Size × Entry Price
