A broker makes money through commissions and spreads. A broker that uses commissions may charge a specified percentage of the spread, the difference between the bid and ask price of the forex pair. However, many brokers advertise that they charge no commissions, and instead make their money with wider spreads.Most forex accounts can be funded with a very small initial deposit, even as low as $50. With leverage, of course, the buying power is much greater than the minimum deposit, which is one reason forex trading is attractive to new traders and investors. Many brokers offer standard, mini and micro accounts with varying initial deposit requirements.
