Formula (per side)

Commission = (Traded volume in USD) × (Commission rate) ÷ 100,000

To calculate traded volume in USD:

Traded volume in USD = (Volume in lots) × (Contract size) × (Execution price) × (Conversion rate to USD)

‍

Example calculation with AUD/CAD

Let’s say:

• You traded 1 lot of AUD/CAD
• Each contract = 100,000 units (standard forex contract size)
• The current price is 0.9000 (1 AUD = 0.9 CAD)
• Conversion rate (CAD → USD) = 0.73. Since the quote currency (CAD) isn’t USD, we convert it to a USD value.
• The commission rate (one side) is $10 per 100,000 USD traded

How to calculate:

1. Find the traded volume in USD: 

1 (lot) × 100,000 (contract size) × 0.9000 (price) × 0.73 (CAD→USD) = 65,700 USD

 So, the total traded volume = 65,700 USD

2. Apply the commission formula:

Commission= (65,700 × 10) ÷ 100,000 = 6.57 USD

So, $6.57 commission per side

3. If you open and close the trade (round trade):

6.57×2 = 13.14

$12 total commission
