When you make a profit,
does your FX broker celebrate or suffer?
The Difference Between
A-Book & B-Book Models
Why it matters for IBs and Traders?

HOW FX COMPANIES PROCESS ORDERS – WHAT ARE A-BOOK AND B-BOOK?

There are two primary order processing models used by FX Brokers: A-Book and B-Book. Understanding the difference between these models is crucial, as it determines the long-term viability for traders and the sustainability of revenue for IBs.
A. How A-Book Works
(Our Company)
Rate Distribution Process
The FX broker receives market prices from Liquidity Providers (Banks) and adds a small fee before delivering the rates to the traders. This fee (spread) constitutes the FX Broker’s primary source of revenue.

Order Flow
A trader submits an order to a forex broker (e.g., $101), which then submits an order to a bank (e.g., $100). The difference between the two amounts is the forex broker’s revenue.
Regardless of the client’s profit or loss, the forex broker earns revenue on each trade

B. How B-Book Works
(Other Companies)
Rate Distribution/Order Flow
FX companies distribute rates to traders based on bank prices.
However, traders’ orders are not sent to banks; instead, they are sent to the FX company.

and trading environments
| ITEM | A-BOOK | B-BOOK |
|---|---|---|
| Company Revenue | Markups on bank prices | Customer loss |
| Relationship between Company vs. Customer Profits |
No conflict | Profits are reversed (customer loss is company gain) |
| When Customers Win | No problems for the company | It becomes a burden on the company. |
| Customer Retention | Easy to trade for long periods | It may not last long. |
| Slippage | Can occur when trading in the market (both advantageous and disadvantageous) | It may be small due to internal processing. |
| Spread | Varies depending on market conditions | It may be fixed or adjustable. |

Why is it important to traders?
There are three things that are important to traders: fair execution, the ability to withdraw, and the ability to trade
for the long term.
The most important difference is the relationship between the company and the customer.
A-Book MODEL
- Even if customers win, the company is not affected. / There is no conflict between the company and customers.
- Withdrawals are unlikely to be an issue. / The company’s profits and losses are not affected.
- Trading restrictions are unlikely to occur. / Winning customers are not a risk.
B-Book MODEL
- If the customer wins, it will be a burden on the company. / The interests of the company and the customer will be in conflict.
- There is a risk of withdrawal problems. / Large profits will be a burden on the company.
- Account restrictions and changes to terms may occur. / The company needs to reduce its risk.

A-Book is designed to support
long-term trading for our clients.
Why is it important for IB?
IB profits are determined by the following formula:
IB Revenue = Number of Clients × Trading Longevity
※ In other words, the most important thing is for customers to do business with us for a long time.
For this reason, many IBs choose companies that will continue to exist for a long time.
We value long-term partnerships, not short-term volume.
