Is Exness A-Book or B-Book?
How Exness executes orders, and what A-book and B-book mean for traders.
Open Exness Account →Exness is neither purely A-book nor purely B-book — it runs a hybrid execution model. It acts as a market maker (B-book) while also hedging flow with external liquidity providers (A-book), so a given order may be internalised or passed through depending on the client and instrument. For traders, the practical question is not the label but execution quality — Exness publishes fast execution speeds and a stop-out and slippage policy you can check before trading.
Delays and slippage may occur. No guarantee of execution speed or precision.
A-book vs B-book — and where Exness fits
- A-book: the broker passes your order to liquidity providers and earns from spread/commission.
- B-book: the broker takes the other side of your trade internally (a market maker model).
- Many brokers, including large ones, use a hybrid of both depending on the client and instrument.
- Exness is a market maker that also routes flow to liquidity providers — a hybrid model.
- What matters most in practice is execution quality: speed, slippage and requotes.

Frequently asked questions
Is Exness a market maker?
Exness is a hybrid broker: it acts as a market maker and also routes order flow to external liquidity providers, depending on the client and instrument.
What type of broker is Exness?
Exness is a hybrid, multi-regulated broker. It combines market-making with routing to external liquidity providers, offering fast market execution on MT4 and MT5 across forex, metals, crypto, energies, stocks and indices.
Delays and slippage may occur. No guarantee of execution speed or precision.
Is Exness a B-book broker?
Not purely. Exness internalises some flow (B-book) and hedges other flow with liquidity providers (A-book) — a hybrid model — rather than being a pure B-book market maker.
Is Exness an A-book broker?
Not exclusively. Exness passes part of its order flow to external liquidity providers, which is A-book routing, but it also acts as a market maker on other flow (B-book). So Exness is best described as a hybrid A-book and B-book broker rather than a pure A-book one.
How do I know if a broker is A-book or B-book?
Brokers rarely state it outright. Judge it by execution quality instead — speed, slippage behaviour and whether you get requotes — and read the order-execution policy. Many large brokers, Exness included, run a hybrid of both.
Is A-book or B-book better for me?
Neither is automatically better for a trader; day-to-day execution quality matters more than the label. Check Exness's execution speed, slippage rule and requote policy, which apply regardless of routing.
Is Exness regulated?
Yes — Exness is a globally regulated broker holding multiple licenses from respected regulators. Always trade with the broker as it operates in your own region.
