Commission is a fee that brokers charge to execute your trades. It's typically charged as a flat rate, percentage of trade volume, or a combination of both. Understanding commission is essential because it directly impacts your trading costs and profitability.
How Commission Works in Forex
Different brokers use different commission models. Some charge a percentage of the trade value, while others apply a flat fee per lot. The commission structure often depends on your account type, the size of your trades, and the broker's business model.
Commission vs. Spreads
Commission is distinct from spreads—the difference between a currency pair's bid and ask price. Some brokers advertise zero commission but compensate with wider spreads. Others charge explicit commissions with tighter spreads. Neither approach is inherently better; the total cost depends on your trading volume and strategy.
Broker Commission Models
| Broker Type | Commission Model | Typical Spreads |
|---|---|---|
| ECN Broker | Percentage-based | Low |
| Market Maker | Flat rate | High |
| STP Broker | Mixed | Moderate |
Impact on Your Trading
High commissions erode profits, especially if you trade frequently. Conversely, the cheapest commissions may come with unreliable execution or limited support. When comparing brokers, factor in commissions alongside spreads, overnight fees (swap rates), and overall service quality to find the best fit for your trading style.
