Transaction Processing

Also, the lack of an exchange means a difference in how trading is actually done. In the stock market an order is submitted to a broker who facilitates the trade with another broker/dealer (over-the-counter) or through an exchange. In spot forex much of the trading done by individuals is actually executed directly with their broker/dealer. That means the broker takes the other side of the trade. This is not always the case, but is the most common approach.

Transaction Costs

The lack of an exchange and the direct trade with the broker creates another difference between stock and forex trading. In the stock market brokers will generally charge a commission for each buy and sell transaction you do. In forex, though, most brokers do not charge any commissions. Since they are taking the other side of all the customer trades, they profit by making the spread between the bid and offer prices.

Some traders do not like the structure of the spot forex market. They are not comfortable with their broker being on the other side of their trades as they feel it presents a type of conflict of interest. They also question the safety of their funds and the lack of overall regulation. There are some worthwhile concerns, certainly, but the fact of the matter is that the majority of forex brokers are very reliable and ethical. Those that are not don't stay in business very long.
