A dealing desk (DD) broker — also called a market maker — is a type of forex broker that creates its own market internally by taking the opposite side of client trades, rather than routing orders to external liquidity providers. When you buy, the dealing desk sells to you. When you sell, the dealing desk buys from you. Dealing desk brokers profit from the spread between bid and ask prices and from client losses. They typically offer fixed spreads, guaranteed execution, and lower minimum deposits — making them common entry points for beginners. The key concern is the inherent conflict of interest: the broker profits when you lose.
Introduction: Understanding How Your Broker Actually Makes Money
Most beginner forex traders open an account, deposit funds, and start trading without asking one of the most important questions in the industry: when I place this order, who is on the other side of my trade?
The answer to that question defines your broker’s business model — and has profound implications for the quality of your execution, the fairness of your pricing, and whether your broker’s financial interests align with yours or directly conflict with them.
A dealing desk broker — the most common broker type encountered by retail beginners — operates a model where the broker itself becomes your counterparty. This guide explains precisely how that model works, what its advantages and disadvantages are, and how to determine whether a dealing desk broker is appropriate for your trading needs.

What Is a Dealing Desk?
A dealing desk is a department within a brokerage that is responsible for processing client orders, managing the broker’s own market exposure, and setting the prices displayed to clients. The term originates from the physical dealing rooms of investment banks, where traders sat at desks managing order flow.
In the context of retail forex brokerage, a dealing desk performs several simultaneous functions:
- Price setting: The dealing desk determines the bid and ask prices shown to retail clients, applying a spread over the benchmark interbank rate
- Order processing: Client orders are received, reviewed, and filled by the dealing desk — manually in older systems, automatically in modern platforms
- Risk management: The desk manages the broker’s net exposure from aggregated client positions, either hedging externally or accepting the risk internally
- Market making: The dealing desk stands ready to buy or sell at all times, ensuring clients can always get a fill — the broker absorbs liquidity risk
How Does a Dealing Desk Broker Work? Step by Step
Understanding the mechanics of a dealing desk reveals both why these brokers are so common and why the conflict of interest concern exists.
Step | What Happens | What the Client Sees |
1 | Client places a buy order for EUR/USD | Clicks Buy at the displayed Ask price |
2 | Order received by dealing desk system | “Order received” confirmation |
3 | Dealer (human or automated) reviews and approves the order | Brief processing delay (ms to seconds) |
4 | Broker takes the opposite side — becomes the seller | Trade confirmation at agreed price |
5 | Broker nets this against other client positions internally | No visibility to client |
6 | Residual risk may or may not be hedged externally | No visibility to client |
Steps 5 and 6 are where the dealing desk model becomes most interesting. If the broker has many clients buying EUR/USD and many clients selling EUR/USD simultaneously, their positions cancel each other out internally — the broker retains the spread on both sides without needing to hedge externally. This internal netting is highly profitable and is a core feature of the market maker business model.
When positions do not net internally — for example, if most clients are all positioned in the same direction — the broker faces residual market exposure. At that point, they may choose to hedge externally (buying or selling in the real interbank market) or to retain the risk, effectively taking a speculative position against their clients.
The Internal Risk Book: How Market Makers Manage Exposure
Most sophisticated dealing desk brokers manage a dynamic internal risk book — a real-time ledger of all open client positions aggregated across the entire client base.
Scenario | Broker Action | Broker Revenue Source |
50% clients long EUR/USD, 50% short | Fully netted — no external hedge needed | 100% of spread on both sides retained |
70% long, 30% short | Net long exposure of 40% — partial hedge externally | Spread + residual position management |
90% long, 10% short | High net exposure — full external hedge or retained risk | Spread + hedging cost/profit |
Client loses on a trade | Profit transferred to broker P&L | Direct client loss = broker gain |
The Conflict of Interest: When a dealing desk broker retains net client exposure without hedging (known as “going B-book”), they profit when clients lose. This is the fundamental tension in the dealing desk model. It does NOT mean all dealing desk brokers are dishonest — regulated market makers operate transparently and legally. But it DOES mean their financial incentives are not aligned with yours as a client.
A-Book vs B-Book: Understanding How Dealing Desks Manage Risk
The terms A-book and B-book are essential vocabulary for understanding the dealing desk model and its variations.
A-Book: The Hedged Model
When a broker A-books a trade, they immediately offset it in the real market — passing the risk to an external liquidity provider. The broker earns the spread markup as revenue regardless of whether the client wins or loses. There is no conflict of interest on A-booked trades.
B-Book: The Internal Model
When a broker B-books a trade, they retain the opposite position internally. If the client profits, the broker loses. If the client loses, the broker profits. The broker’s revenue is not just the spread — it includes the client’s actual losses.
Hybrid A/B-Book: The Most Common Approach
Most modern dealing desk brokers operate a hybrid model. They selectively A-book trades from consistently profitable traders (hedging externally to eliminate exposure) while B-booking trades from less experienced or consistently losing traders (retaining the opposite exposure to profit from their losses).
Model | Client Trade Goes To | Broker Revenue | Conflict of Interest |
A-Book (pure STP/ECN) | External liquidity provider | Spread markup or commission only | None — broker earns regardless of outcome |
B-Book (pure dealing desk) | Broker’s internal risk book | Spread + client losses | High — broker profits when client loses |
Hybrid A/B | Either, depending on client profile | Spread + selective B-book profits | Moderate — depends on which book your trades go to |
Most retail brokers — even those that market themselves as “STP” or “ECN” — operate some degree of hybrid A/B booking. The transparency of this practice varies enormously. Genuinely transparent ECN brokers who A-book 100% of trades are rare but do exist and are documented on CompareBroker.io.
How Dealing Desk Brokers Set Their Spreads
One of the defining characteristics of a dealing desk broker is control over pricing. Unlike ECN brokers who display raw interbank prices, dealing desk brokers set their own bid and ask prices — typically with reference to the interbank rate but with freedom to adjust.
Spread Type | How Set | Typical EUR/USD Range | Behaviour During News |
Fixed Spread | Set by broker — does not change with market conditions | 1.5–3.0 pips | Stays fixed (broker absorbs volatility) |
Fixed + Widening | Fixed in normal conditions, widens during events | 1.0–2.0 normal, 5–15 during news | Broker widens proactively |
Variable (dealer-set) | Adjusted by dealing desk based on conditions | 1.0–2.5 pips | Can widen significantly |
The ability to offer fixed spreads is one of the genuine advantages of the dealing desk model. Fixed spread brokers give retail traders — especially beginners — cost predictability that variable spread ECN models cannot provide during volatile conditions. Compare them at CompareBroker.io.
Advantages of Trading With a Dealing Desk Broker
Despite the conflict of interest concerns, dealing desk brokers offer several genuine advantages that explain why they remain extremely popular, especially for beginners.
1. Fixed Spreads and Cost Predictability
Knowing that EUR/USD will always cost you 2.0 pips to trade — regardless of market conditions — simplifies strategy planning, backtesting, and risk calculation. Variable spreads on ECN platforms can spike to 10, 20, or even 50 pips during major news events.
2. Guaranteed Order Execution
Market makers guarantee to fill your order — they are always willing to be the counterparty. On ECN platforms with genuine liquidity dependence, slippage or partial fills can occur during low liquidity. The dealing desk eliminates this by always providing a price.
3. Low or Zero Minimum Deposits
Dealing desk brokers frequently offer very low minimum deposits — sometimes as low as $10 or $50 — making them accessible entry points for beginners. ECN brokers with raw spreads typically require higher minimums. Compare low-deposit micro account brokers.
4. Simpler Platform Experience
Dealing desk brokers typically offer streamlined platforms with simplified interfaces — ideal for beginners who do not yet need the full depth-of-market transparency that ECN platforms provide.
5. Demo Accounts Mirroring Live Conditions
Most dealing desk brokers offer demo accounts with the same fixed spreads and execution model as their live accounts — giving beginners a genuinely representative practice environment. Explore forex demo accounts from regulated brokers.
Disadvantages and Risks of Dealing Desk Brokers
The conflict of interest at the heart of the dealing desk model creates several practical risks that traders need to understand.
1. Conflict of Interest on B-Booked Trades
When your trades are B-booked, your broker profits when you lose. This creates a subtle but real incentive for the broker to set spreads wider than necessary, delay executions, or selectively widen prices at crucial moments to trigger stop losses.
2. Stop Hunting (In Unregulated Contexts)
Because dealing desk brokers know exactly where their clients have placed stop loss orders, and because they control the prices shown to those clients, there is a theoretical opportunity to briefly widen spreads to trigger stop losses deliberately. Regulated dealing desk brokers are prohibited from this practice, but unregulated offshore brokers have historically engaged in it.
3. Requotes
In fast markets, a dealing desk broker may reject your order at the requested price and offer a different (usually worse) price — a requote. This is rare on automated platforms but can be problematic for scalpers and news traders who need instant execution at exact prices.
4. Potential for Platform Manipulation
Because the dealing desk sets prices rather than displaying interbank prices directly, there is a structural possibility for price manipulation. Again, this is regulated against in Tier-1 jurisdictions but remains a risk with unregulated brokers.
RISK ALERT: The dealing desk risks described above are most acute with UNREGULATED offshore brokers. FCA-regulated (UK), ASIC-regulated (Australia), and CySEC-regulated (EU) dealing desk brokers are subject to strict rules on best execution, fair pricing, and prohibition of stop hunting. Always choose regulated brokers. Compare FCA-regulated brokers at CompareBroker.io.
How to Identify a Dealing Desk Broker
Brokers are not always transparent about whether they operate a dealing desk. Here are practical ways to identify them:
- They offer fixed spreads — ECN brokers by definition cannot offer truly fixed spreads
- Their website uses the term “market maker” or describes “internal execution”
- They guarantee fills with no slippage — only a dealing desk can guarantee this
- Their account documents mention “acting as principal” in trades — meaning they take the opposite side
- Their order execution policy describes an internal risk management process
- Their spreads do not widen during normal market hours — true ECN spreads reflect live liquidity
When comparing brokers on CompareBroker.io, look for the execution model disclosure in each broker’s profile. Transparency about dealing desk vs NDD status is one of the key data points in the comparison tool.

Frequently Asked Questions: Dealing Desk Brokers
Is a dealing desk broker always bad for traders?
Not at all. Regulated dealing desk brokers serve an important role in the retail forex ecosystem. They provide accessible entry points for beginners, offer fixed spreads for cost certainty, and guarantee execution at all times. The “bad” reputation stems specifically from unregulated brokers abusing the model — not from the model itself when properly supervised.
Can a dealing desk broker manipulate prices?
A regulated dealing desk broker is legally prohibited from price manipulation by their financial regulator (FCA, ASIC, CySEC). Their order execution policies are audited and client complaints have regulatory oversight. Unregulated brokers have no such constraint — this is the primary reason why regulation is non-negotiable when choosing any broker.
What is the difference between a dealing desk and a market maker?
The terms are essentially synonymous in retail forex. A market maker is a broker that creates a market for clients by always being willing to buy or sell — and the mechanism by which they do this is their dealing desk. All market makers use a dealing desk; not all dealing desk operations are called market makers (some use hybrid models).
Should a beginner use a dealing desk broker?
For an absolute beginner, a regulated dealing desk broker offers genuine advantages: fixed spreads, simple platforms, low minimums, and guaranteed execution. As you gain experience and trading volume increases, transitioning to an ECN/STP broker for better pricing and transparency often makes sense. Start with a demo account to understand any broker’s execution model before depositing real funds.
Conclusion: Know Your Broker’s Model Before You Trade
The dealing desk model is not inherently corrupt — it is a legitimate, regulated business model that serves a genuine market need. Millions of retail traders successfully use dealing desk brokers every day. The keys are: choosing a properly regulated broker, understanding that fixed spreads come with a different cost structure than variable ECN spreads, and knowing that on B-booked trades, your broker has a financial interest in your position.
