Comment utiliser ce calculateur
Position sizing answers the question: how many units should I trade so that if my stop loss is hit, I lose no more than X% of my account? Keeping risk consistent per trade is one of the most important habits of professional traders.
Lots = (Account × Risk%) ÷ (Stop pips × Pip value per lot)
Inputs explained
- Account balance: your total trading capital in your account currency.
- Risk per trade (%): the percentage of your account you are willing to lose on this trade. Most risk managers recommend 1–2%.
- Stop loss (pips): the distance in pips from your entry to your stop loss order.
- Pip value per standard lot: how much one pip is worth in your account currency for 1 lot. Use the Pip Calculator on this site to find the exact value for your pair.
Worked example
Account: $10,000, risk: 1%, stop loss: 20 pips, pip value: $10/lot (EUR/USD, USD account).
Risk amount = $10,000 × 1% = $100
Lots = $100 ÷ (20 × $10) = 0.5 lots (50,000 units)
