Formula Explained

The position size calculation is based on the following formula:

Position Size (lots) = (Account Balance × Risk Percentage) / (Stop-Loss Distance × Pip Value × Lot Size)

Where:

Account Balance - Your total trading account balance
Risk Percentage - The percentage of your account you're willing to risk per trade (typically 1-2%)
Stop-Loss Distance - The distance between your entry price and stop-loss price in pips
Pip Value - The monetary value of one pip for the currency pair
Lot Size - The standard lot size for the currency pair (typically 100,000 units)

This formula helps ensure you're risking a consistent amount of capital per trade, which is a fundamental principle of risk management in Forex trading.

Worked Example

Let's walk through a practical example to illustrate how the calculator works.

Example Scenario

Account Balance: $10,000
Currency Pair: EUR/USD
Risk Percentage: 1%
Stop-Loss Distance: 50 pips

Calculation Steps

Calculate the maximum risk amount: $10,000 × 1% = $100
Determine the pip value for EUR/USD (typically $0.0001 per pip)
Calculate the position size: ($100) / (50 pips × $0.0001/pip × 100,000 units/lot) = 0.2 lots

Therefore, the recommended position size for this trade would be 0.2 lots.

Note: The actual pip value may vary slightly depending on the current exchange rate and the broker's pip calculation method.
