Is Exness a Book or B Book (2026): Account Types and Regulation

Few questions in retail trading cause as much argument as this one: is my broker an A book or a B book? On forums, the A book is described as "honest" and the B book as "a casino", and people sometimes claim to know exactly how a particular broker handles each order. The truth is more careful. Brokers rarely publish a precise breakdown, practice can be a mix, and the label alone does not decide whether you will be treated fairly. This guide explains what A book and B book mean, how a hybrid model works, why the question matters to you as a trader, what the documents of a broker such as Exness are likely to tell you, and how to test conditions yourself. We do not claim to know how Exness routes any particular order, and nobody outside the company can, so we do not give a verdict. We show you where to look and what you can verify, which is more useful than a rumour. The broker's own documents are the right starting point. You can open the official Exness site and find its order execution and legal documents and look for the order execution policy and the client agreement for your entity, then compare what they say with the rest of this guide. As always, trading leveraged products carries a high risk of loss, whatever the model behind the screen.

Key Facts

• In an A book model, the broker passes client orders to liquidity providers or the market; in a B book model, the broker takes the other side of client trades itself.
• Many brokers use a hybrid, routing some flow externally and keeping some internally, based on rules they do not usually publish in detail.
• The model alone does not prove fairness; execution quality, conflicts management and regulation matter.
• Execution policies, client agreements and regulatory disclosures are the documents that describe how orders are handled.
• You can test execution on a demo and with small live trades by tracking spread, slippage and requotes.

What A Book and B Book Mean

The terms come from how a broker handles risk. In an A book, sometimes called agency or straight-through processing, the broker acts as an intermediary. When you buy EUR/USD, the broker sends a matching order to a liquidity provider such as a bank or a pricing aggregator, and earns a spread markup or a commission. The broker does not gain or lose when your trade wins or loses, apart from the fees.

In a B book, sometimes called market making or dealing desk, the broker takes the opposite side of your trade. If you buy, the broker effectively sells to you and holds that position. If you win, the broker loses, and if you lose, the broker gains. Brokers using this model manage their overall risk, perhaps by hedging with the market when the net exposure becomes large.

Neither term describes a regulatory category by itself. Both models are used by licensed firms, and the rules differ by regulator. In some jurisdictions the regulator requires disclosures about conflicts of interest where a broker is the counterparty to clients' trades.

Choosing a Timeframe and Holding Period

Scalpers use one-minute to five-minute charts, day traders use fifteen-minute to hourly, and swing traders use four-hour to daily. Shorter timeframes produce more signals, more costs and more noise; longer ones produce fewer, slower trades with wider stops.

Pick the timeframe that fits your schedule and temperament. If you work during the day, a four-hour or daily approach checked twice daily may suit you better than trying to scalp between meetings.

Why Hybrid Models Are Common

In practice, many brokers do not use a pure model. A hybrid broker may internalise part of its order flow, for example, the small and short-term trades that are unlikely to move the market, and pass the rest to the market. The criteria might include account size, trading style, instrument, trade duration or the outcome history of a client.

Hybrid models are not necessarily bad. Internalising small, random flow can lower the broker's costs and sometimes allows tighter prices. The concern arises when the rules are hidden, when profitable clients are treated differently from unprofitable ones in ways that are not disclosed or when the broker's incentives conflict with fair execution.

This is why the question "is it A or B" is too blunt. A better question is: how does this broker describe its execution, is its description consistent with what I see, and does the regulator supervise conflicts of interest?

One Dollar View, Many Pairs

Many pairs include the US dollar, so several positions can really be one bet. If you are long four pairs against the dollar and it rallies, all four lose together. Use a simple table of correlated pairs and cap total exposure per currency.

Spread your risk across truly different ideas, and keep position count modest. More trades are not more diversification; they are often more noise.

What a Broker Usually Discloses

Regulated brokers must provide an order execution policy, a conflicts-of-interest policy and a risk disclosure, though the content and detail depend on the regulator. In these you may find statements such as whether the firm acts as principal or agent, how orders are executed, whether requotes or last look are used, how slippage is treated and which venues or liquidity providers are used, sometimes only in general terms.

When you read the documents for Exness, or for any broker, look for these items:

• Whether the firm states that it acts as principal, agent or both.
• The description of execution types for different account types.
• The policy on slippage, requotes, partial fills and rejections.
• The stated treatment of conflicts of interest.
• The complaint procedure and external dispute route.
• Any statement on negative balance protection and compensation schemes.

These documents are the closest thing to an official answer. If a statement is unclear, ask support to clarify in writing, and keep the answer.

Trading Psychology and Discipline

Technical skill rarely decides who survives. Discipline does. The same few emotional traps catch nearly everyone: revenge trading after a loss, moving a stop because the trade will surely come back, oversizing after a win, and trading out of boredom.

Build rules that remove decisions in the heat of the moment. Write a one-page plan covering which markets you trade, which sessions, the maximum number of trades per day, the maximum loss per day, and what you do after two losses in a row. When the daily loss limit is reached, you close the platform. No exceptions.

• Review your journal weekly, looking for patterns in mistakes rather than outcomes.
• Avoid trading when tired, rushed or upset.
• Do not size up to win back a loss.

Account Types and Execution

Brokers often differentiate account types by pricing style: a no-commission type with spreads that include the broker's margin, and a raw-spread type with a commission. Exness describes several, such as Standard, Cent, Pro, Raw Spread and Zero. Account types can influence execution settings, for example, maximum lot size, order types allowed or execution mode. Some brokers describe their professional types as having "market execution" without requotes, while describing others as "instant execution" with a price tolerance.

We cannot tell you which execution mode applies to which Exness account for your entity. The specification pages and the platform's account information show it. In MetaTrader, the symbol properties list the execution mode, for instance, market execution or instant execution, along with the minimum distance for stops. Read them, and ask support if the information differs from the website.

Regulation and Why It Matters More Than the Label

A broker's regulator sets the standard for how clients are treated, for example: requirements to execute orders on terms that are the best reasonably available, to keep client funds separate from company funds, to manage conflicts and to handle complaints. These obligations apply whatever the book model is.

Different entities have different regulators and different levels of protection. Exness has described entities in several jurisdictions. Which one serves you depends on your country. Check its regulatory page for your entity and look up the regulator's public register yourself. Then read the regulator's guidance for investors if it has any.

When a broker is regulated in a place with strong client-protection rules and active enforcement, the risk of abusive execution is lower, though not zero. When it is regulated in a place with lighter supervision, you should be more careful, test more and keep balances small. None of this is an accusation against any specific firm; it is a framework for your own judgement.

Signs You Can Test Yourself

You do not have to guess. Use your own data.

1. **Spread behaviour.** Record the spread at several times of day on a demo and live account. Compare with the published spread for the account type.
2. **Slippage.** Place small market orders and note the difference between the price you clicked and the fill price, in quiet markets and during news. Check whether slippage is symmetric, sometimes in your favour and sometimes against.
3. **Stop and limit behaviour.** Check whether stops are triggered at the stated level, whether spikes appear on your account and not on others, and whether limit orders are filled when price touches them.
4. **Rejections and requotes.** Count how often orders are rejected or requoted, and under what conditions.
5. **Speed.** Note the time between sending an order and the confirmation.
6. **Consistency.** Compare your demo, live and a second broker's demo prices at the same time.
7. **Withdrawals.** Test a small withdrawal early.

One or two odd events prove nothing; a repeated pattern does. Keep screenshots with time stamps and the ticket numbers.

What a Profitable Trader Might Notice

There is a popular claim that B book brokers restrict profitable traders. Some brokers do state in their terms that they may adjust conditions, such as limiting certain strategies or changing execution, for clients who exploit latency or pricing errors. These clauses are disclosed in agreements and are usually aimed at behaviours such as arbitrage or abuse.

If your results become strong, keep your trading in line with the stated rules and keep records. If you notice changes in your conditions, ask support to explain them with reference to the terms. If you are not satisfied, use the complaint route. It is also reasonable to compare with other brokers to see whether execution differs.

You can check which account types and entity apply to your country before registering and open its demo alongside your main account to compare prices and fills over a week. Differences are information, not proof, but they can guide questions you ask.

What to Do With the Answer

Even if you could know the model exactly, what would you do? If you found that a broker is B book, you would still ask whether it discloses conflicts, executes fairly and pays withdrawals. If you found that it is A book, you would still need to check regulation and costs. The label is one input among many.

A practical approach is to choose brokers with clear regulation, transparent documents, reasonable costs and a record of paying withdrawals, then keep your own evidence by trading small, logging your executions and testing withdrawals. If anything in that evidence troubles you, change the amount at risk or change the broker.

A Worked Example of an Execution Test

Here is a simple experiment you can run. On a demo account and on a small live account, choose one liquid pair and a quiet hour. Place ten small market orders of the same size, five buys and five sells, and close each one immediately. For each, write down the price you saw when you clicked, the filled price, the spread at that moment and the time. Do the same around a scheduled news release, with even smaller size on live, or on demo only if you prefer.

Then compare. In quiet conditions, the difference between the clicked price and the fill should be small and should not favour one side consistently. Around news, you should expect more slippage and wider spreads, and a fair environment shows slippage both for and against you. If you see that every fill is worse than the click, in quiet markets, repeatedly, that is a pattern worth raising with support. The numbers in your notebook are far more persuasive than a general complaint.

Be careful about the limits of this test. A short sample can mislead, a demo may use different settings and your own connection speed matters. Repeat on different days before drawing conclusions, and compare with another provider's demo on the same pair at the same time.

Conflicts of Interest and How Brokers Should Handle Them

When a broker may profit from client losses, it has a conflict of interest, and regulators in many places require firms to identify and manage it. Management can include separating the pricing team from the dealing team, monitoring for unfair practices, applying consistent rules to all clients and disclosing the nature of the conflict. Some regulators require that firms warn clients if they act as the counterparty.

As a client, look for the conflicts-of-interest policy and read how it describes the risk and the controls. A policy that speaks in generalities and avoids saying who is the counterparty is a signal to ask more questions. A policy that explains the model and the measures taken is a better sign. Remember that written policy and real practice can differ, which is why your own tests matter.

The Role of Negative Balance Protection and Compensation Schemes

Another practical difference between entities is the safety net. Negative balance protection means you cannot lose more than your account balance in specified circumstances. Compensation schemes may pay limited amounts if a licensed firm fails, depending on the jurisdiction. These protections vary by regulator and may not exist for some entities.

Check the documents for your entity. If protections exist, note the limits and conditions. If they do not, treat that as a reason to keep balances smaller and withdraw profits regularly. A safety net is more important than the A book or B book label, because it determines what happens in the worst case.

Practical Tips for Choosing Without Certainty

You will probably never know exactly how a broker routes your orders, so manage the uncertainty. Start with a small live balance. Record your executions. Withdraw profits regularly instead of leaving large sums as equity. Avoid strategies that depend on tiny price edges, such as scalping around news, unless you have verified execution. Keep documents and messages. Diversify across brokers if you hold significant capital, and avoid putting everything into a single provider.

Above all, do not choose a broker based on a rumour about its model. Choose on evidence you can gather yourself, and be ready to change if the evidence changes.

Keeping a Simple Execution Log

A log turns doubts into data. Create a sheet with columns for date, time in GMT, instrument, order type, size, clicked price, fill price, spread, news nearby and notes. Add a row for every trade for a month. At the end, calculate the average slippage in quiet and busy times and the number of rejections. Keep the log updated and share it with support if you raise a concern. A clear record makes it easier for the company to investigate and easier for you to see your own habits too.

Frequently Asked Questions

We cannot verify how any firm routes each order. Read its execution policy and conflicts policy for your entity, and test conditions yourself.

What is the difference between A book and B book?

In an A book the broker passes orders to the market; in a B book it takes the other side of client trades.

Is B book illegal?

No, it is used by licensed firms, but regulators require disclosures and fair treatment, and rules differ by jurisdiction.

Do hybrid brokers exist?

Yes. Many route some flow externally and keep some internally under rules they seldom publish in detail.

How can I test my broker's execution?

Record spreads and slippage at different times, check how stops and limits fill, count rejections and compare with another broker's demo.

Does the account type change execution?

It can. Check the execution mode and conditions for your account type in the platform and the documents.

Which matters more, the model or regulation?

Regulation, transparency, costs and withdrawal performance matter at least as much as the label.

Summary: Verify, Do Not Assume

Whether Exness is an A book or a B book cannot be proved from outside, and the label alone does not decide quality. Read the execution and conflicts policies for your entity, check the regulator, run your own execution tests, keep records and trade small until the evidence supports trust.

📌 Important: CFD Risk Warning and Disclosure

CFDs and leveraged forex are complex instruments. Because you trade on margin, a small price move against you can remove a large part of your balance quickly, and a majority of retail traders lose money when trading CFDs. Before you open or fund any account, make sure you understand how leverage, margin, swaps and stop-outs work, and only trade with money you can afford to lose. Examples in this article are illustrations, not forecasts, and past performance is not a reliable guide to future results.
