B-Book vs A-Book Brokers What’s the difference & does it matter?

This model provides traders with fair and transparent trading conditions, as their orders are executed directly in the market, leading to potentially tighter spreads and faster execution speeds. The B-Book is a trading execution method where brokers act as the counterparty to their clients’ trades. In this model, brokers do not forward clients’ orders directly to external liquidity providers or the market; instead, they internally match client orders and take the opposite position. This means that when a client buys a particular financial instrument, the broker sells it, and vice versa. A-Book brokers, also known as Straight-Through Processing (STP) brokers, work differently compared to other brokers. They don’t trade against you as some other types of brokers do.

In a pure B-Book model, brokers can mitigate counterparty risks by internally offsetting trades among their clients. This involves matching a client’s trade with another client’s opposing trade. By doing this, the broker can neutralize the market risk to some extent without needing to hedge externally. The second significant income source for B-Book brokers is the losses of their traders.
