How to Use

📝 Formula

Lot Size = Risk Amount ÷ (SL Pips × Pip Value)

Margin = (Lots × Contract Size × Price) ÷ Leverage

Forex: 100,000 units/lot; Gold: 100 oz/lot

⚠️ Important Notes

  • Ensure sufficient margin in account
  • Recommended risk per trade: max 2%
  • Risk/Reward ratio: minimum 1:2
  • High leverage increases risk, use cautiously
  • Prices auto-update every 5 minutes

Real Example

Scenario:

  • Account Balance: $10,000 (USD)
  • Risk Percentage: 2%
  • Leverage: 1:100
  • Stop Loss: 50 pips
  • Take Profit: 100 pips
  • Currency Pair: EUR/USD @ 1.0850

Calculation:

  • 1.Risk Amount = $10,000 × 2% = $200
  • 2.Pip Value = $10 (EUR/USD standard)
  • 3.Lot Size = $200 ÷ (50 × $10) = 0.4 lots
  • 4.Margin = (0.4 × 100,000 × 1.0850) ÷ 100 = $434
  • 5.Potential Profit = 0.4 × 100 × $10 = $400

💡 Key Insight:

Correct position sizing ensures: Fixed risk at $200 (2%), 1:2 risk/reward ratio, margin usage only $434 (4.34%), allowing multiple positions without margin call.
