What is the A Book and B Book that forex brokers use? Forex trading is different from investing in shares or futures, because a broker can choose to trade against his clients. This system used by “Dealing Desk” Market Maker brokers is known as “B booking”. STP best forex broker affiliate programs send all of their clients’ trades to the real market or to liquidity providers.
They therefore use the “A booking” system. However, many forex brokers use a hybrid model which uses a B Book for clients who lose money and an A Book for the profitable clients. In the regulated futures contract and stock markets, all transactions are sent to an exchange that confronts buyers’ and sellers’ orders by sorting them according to price and time of arrival. These forex brokers make money by increasing the spread or by charging commissions on the volume of orders. Therefore, there are no conflicts of interest, these brokers earn the same amount of money with both winning and losing traders.
This type of forex broker is becoming increasingly popular because forex traders are reassured by the absence of this conflict of interest, as well as the fact that these brokers have an incentive to have profitable traders since they will increase their trading volumes and therefore the brokers’ profits. Forex brokers that use a B Book keep their clients’ orders internally. They take the other side of their clients’ trades, which means that the brokers’ profits are often equal to their clients’ losses. Brokerage firms are able to manage the risks associated with the holding of a B Book by using certain risk management strategies: internal hedging through the matching of opposite orders submitted by other clients, spread variations, etc. It is obvious that this model generates conflicts of interest between brokers and their clients.
