How Is ECN Commission Charged When Trading Less Than 1 Lot?

Commission is charged proportionally, based on the lot size you trade.

If the commission is $3.5 per side, per 1.0 lot, then trading a smaller volume means paying a smaller commission.

Example (ECN Account):

• Commission: $3.5 per side, per 1.0 lot

• Trade size: 0.2 lots (EUR/USD)

Commission calculation:

• Opening the trade:
  $3.5 × 0.2 = $0.70

• Closing the trade:
  $3.5 × 0.2 = $0.70

👉 Total Round Turn commission: $1.40
