Formula Explained

The position size is calculated using this formula:

Position Size = (Account Balance × Risk Percentage) ÷ (Stop-Loss Distance × Price per Unit)

Where:

Account Balance - Total funds available for trading
Risk Percentage - Percentage of account you're willing to risk per trade
Stop-Loss Distance - Price difference between entry and stop-loss
Price per Unit - Current price of the commodity

For example, if you have $10,000 in your account, want to risk 1% per trade, and your stop-loss is 50 points with a commodity price of $20 per unit:

Position Size = ($10,000 × 0.01) ÷ (50 × $20) = 10 units

Worked Example

Let's say you have $15,000 in your trading account and want to risk 2% of your account per trade. You're trading gold futures with a current price of $1,800 per ounce and plan to set a stop-loss 100 points below entry.

Account Balance: $15,000
Risk Percentage: 2%
Stop-Loss Distance: 100 points
Price per Unit: $1,800

Using the formula:

Position Size = ($15,000 × 0.02) ÷ (100 × $1,800) = 16.67 ounces

You should trade approximately 16.67 ounces of gold futures with this position size.
