📚 How to Use This Calculator
The position size calculator determines exactly how many lots/units you should trade to match your risk management plan. It supports all 28 major and minor forex pairs with accurate pip value calculations.
The 3 Categories of Pairs
Position sizing requires proper pip value conversion based on pair structure:
- Category A (Quote = Account Currency): EUR/USD, GBP/USD, etc. — Pip value = pipSize × 100,000
- Category B (Base = Account Currency): USD/JPY, USD/CHF, USD/CAD — Pip value = (pipSize × 100,000) ÷ currentPrice
- Category C (Cross Pairs): All other pairs — Pip value = (pipSize × 100,000) × crossRate
Cross Rates
Cross rates enable accurate pip value conversion for cross pairs. Update these 7 base rates from your broker for maximum accuracy.
Lot Size Reference
- 1 Standard Lot: 100,000 units
- 1 Mini Lot: 10,000 units (1/10th)
- 1 Micro Lot: 1,000 units (1/100th)
- 1 Nano Lot: 100 units (1/1,000th)
Risk Management Formula
Position Size (lots) = Risk Amount ÷ (Stop Loss Pips × Pip Value Per Lot)
Best Practices
- Risk 1-2% per trade for professional money management
- Keep stop losses tight (20-50 pips) for better risk:reward ratios
- Update cross rates daily from live market data
- Verify calculations with your broker's pip conventions
- Use nano lots for testing or ultra-conservative sizing
