Commission depends on your account type.
Standard account: no commission. Your costs are in the spread.
Raw account: $2.50 per lot, charged when you open a trade and again when you close it. That's $5.00 per lot round turn.
Raw commission = $2.50 × lots × 2
Raw trade size | Calculation | Commission (round turn) |
1 lot | $2.50 × 1 × 2 | $5.00 |
0.1 lot | $2.50 × 0.1 × 2 | $0.50 |
0.01 lot | $2.50 × 0.01 × 2 | $0.05 |
