ECN vs STP vs Market Maker Brokers Explained
ECN, STP or market maker? Learn how each forex broker type works, the costs, pros and cons, and how to pick a trusted broker that fits your trading style.
ECN, STP and Market Maker Brokers Explained Simply
Sooner or later, every trader who starts comparing brokers runs into three confusing acronyms. One broker says it’s ECN. Another says STP. A third says nothing about it at all, and a forum comment says you should “never trade with a market maker.”
It sounds technical, but the idea underneath is simple: what happens to your order after you click Buy or Sell? The answer affects the spreads you pay, the speed of your execution and, in one model, whether your broker has a conflict of interest with you.
Quick answer: A market maker broker takes the other side of your trade through a dealing desk. An STP broker passes your order straight to liquidity providers without a dealing desk. An ECN broker places your order into a network where it can interact with prices from multiple participants, usually with a raw spread plus commission. None is automatically best, and many brokers use a mix. Forex trading carries risk whichever model you use.
I’ve explained this to beginners for six years, and the clearest way to understand it is to follow one order from your screen to the market. Let’s do that.
First, the basics: what does a broker actually do with your order?
When you open a trade, someone has to take the other side of it. If you buy EUR/USD, someone sells it to you. The broker’s execution model describes who that someone is and how your order reaches them. If you’re new to this, our guide on how does a forex broker work covers the full journey from click to fill.
There are three common models.
1. Market maker brokers (dealing desk)
A market maker broker creates a market for its clients. Instead of sending every order to an outside market, it may take the opposite side of your trade itself, which is why the model is often called a dealing desk or “B-book.”
How it works: you buy, and the broker sells to you from its own book. It may keep that risk, or it may hedge part of it elsewhere, depending on its policy.
Typical features:
Spreads are often quoted as fixed or semi-fixed, and many accounts have no separate commission.
Orders can fill quickly, even in thinly traded conditions.
Pricing comes from the broker rather than directly from the open market.
The honest concern: because the broker may profit when clients lose, there is a potential conflict of interest. That isn’t automatically abusive, and regulated market makers operate under rules on fair pricing and best execution. But it is why transparency matters so much with this model.
2. STP brokers (straight-through processing)
An STP broker routes your orders straight through to its liquidity providers, such as banks and other institutions, without a dealing desk intervening.
How it works: you buy, and the broker passes the order on to a provider who sells to you. The broker earns by adding a small markup to the spread, or sometimes a commission.
Typical features:
No dealing desk taking the other side of your trade.
Spreads are usually variable and tend to be tighter than a typical fixed spread, though they widen when markets are volatile.
Execution depends on the broker’s liquidity providers.
The honest trade-off: because prices come from outside providers, you can see slippage, meaning your order fills at a slightly different price than you clicked, especially around major news.
3. ECN brokers (electronic communication network)
An ECN broker connects you to an electronic network where your orders can interact with prices from multiple participants, including banks, institutions and other traders.
How it works: the broker passes your order into the network and charges a commission, while the spread reflects market prices directly, often as a “raw” spread that can be very tight.
Typical features:
Raw or very tight spreads, plus a commission per lot.
Access to market depth on some platforms.
Greater price transparency, since quotes are drawn from the network.
The honest trade-off: the commission is an extra cost to count, spreads can widen sharply in fast markets and not every ECN account suits small beginners. In practice, the label is also used loosely, so verify what a broker actually offers.
ECN vs STP vs market maker: side-by-side
| Market maker | STP | ECN | |
|---|---|---|---|
| Who takes the other side? | Often the broker | Liquidity providers | Network participants |
| Dealing desk? | Yes | No | No |
| Typical spread | Fixed or semi-fixed | Variable, markup added | Raw, variable |
| Commission | Often none | Sometimes | Usually yes |
| Price source | Broker-quoted | Liquidity providers | Multiple participants |
| Possible conflict of interest | Higher, if broker keeps your trade | Lower | Lower |
| Slippage risk | Lower in quiet markets, depends on policy | Present in fast markets | Present in fast markets |
| Often suits | Beginners wanting simple pricing | Traders wanting no dealing desk | Active traders sensitive to spread |
Treat this table as a guide to the general models, not a rule for every broker. Real execution policies vary.
A quick cost example
Costs are where these models differ most in daily trading. Here is an illustrative example, not a quote from any broker. Assume a trade of 1 standard lot on EUR/USD, where one pip is worth roughly $10.
| Account style | Spread | Commission | Total cost per lot |
|---|---|---|---|
| Spread-only account | 1.2 pips = $12 | $0 | $12 |
| Raw spread account | 0.2 pips = $2 | $7 round trip | $9 |
In this example, the raw spread account is cheaper per trade. But the picture changes if spreads widen, if you trade small sizes or if the commission is higher. The only reliable way to compare is to add spread and commission together on the pairs and sizes you actually trade. Our guide on forex broker fees shows how to do that properly.
Which type is best for you?
There’s no universal winner. Here are some honest guidelines.
If you’re a beginner learning the basics, a simple spread-only account can be easier to understand, because there’s one cost to watch. Practise first on a demo account so you can see real spreads without risk.
If you trade often or in small price moves, like scalping, tight raw spreads can matter more, and commission-based accounts may suit you.
If you trade around major news, pay attention to how a broker handles fast markets, because slippage and spread widening can affect any model.
If transparency matters most to you, look for a broker that explains its execution model clearly and doesn’t dodge the question.
The labels can be misleading
Here’s something forum posts rarely admit: the terms ECN, STP and market maker are not always used strictly. Some brokers use a hybrid model, routing some orders externally and handling others internally. Some advertise “ECN-style” pricing without a true network. Others use “no dealing desk” in marketing while operating in more complex ways.
So don’t judge a forex broker by the acronym alone. Instead, read its order execution policy, which regulated brokers are generally required to publish, and look at how it describes where orders go, how conflicts of interest are managed and what happens in fast markets.
How to check any broker’s execution model
Ask these questions before you deposit:
Does the broker publish a clear order execution policy?
Does it say whether it acts as principal (taking the other side) or passes orders on?
Are spreads, commissions and swap fees listed in plain language?
Is it regulated, and can you verify the licence on the regulator’s own website?
How does it handle slippage and requotes, and does it say so?
Does it keep client funds separate from company money?
A trusted broker answers these openly. If you have to dig or the answers are vague, treat that as a warning. Our checklist on what makes a trusted broker and our guide on how to choose a forex broker go through the verification steps in detail.

Conclusion: Final thoughts
ECN, STP and market maker describe how your order travels and who it meets on the way. A market maker may take the other side itself, an STP broker passes your order to liquidity providers and an ECN broker connects you to a network, usually with a raw spread plus commission. Each has trade-offs in cost, speed and transparency, and none removes the risks of trading itself.
For most traders, the right question isn’t “which acronym is best?” but “which broker explains its model clearly, charges fairly and is properly regulated?” Learn the basics, compare total costs rather than headline spreads, test on a demo account and choose a provider you can verify. Forex always carries risk, but understanding what happens to your order puts you in a stronger position than most.
Frequently asked questions
What is the difference between ECN, STP and market maker brokers?
A market maker broker may take the other side of your trade through a dealing desk. An STP broker routes your order straight to liquidity providers without a dealing desk. An ECN broker places your order into an electronic network with multiple participants, typically charging a raw spread plus commission. Many brokers combine elements of these models.
Is an ECN broker better than a market maker?
Not automatically. ECN accounts can offer tighter spreads and more price transparency, but they usually add a commission. Market maker accounts may offer simpler pricing, though they involve a potential conflict of interest if the broker takes the other side. The better choice depends on your trading style, costs and how transparent the broker is.
Is an STP broker the same as an ECN broker?
No, though they’re similar. Both avoid a dealing desk, but an STP broker routes orders to liquidity providers and usually earns through a spread markup, while an ECN broker connects orders to a network and typically charges commission on top of a raw spread.
Are market maker brokers safe?
They can be, provided they’re properly regulated and transparent. Regulation requires rules on fair pricing, client money and best execution. The risk lies in unregulated or opaque providers, so verify the licence on the regulator’s website and read the execution policy before depositing.
Which broker type is best for beginners?
Many beginners find a simple spread-only account easier to understand, since there’s one main cost to track. The most important step is to practise on a demo account and choose a regulated broker with clear fees. The execution label matters less than transparency and risk management.
Do ECN brokers have slippage?
Yes, slippage can happen with any execution model, especially during major news or low liquidity. An order may fill at a slightly different price than requested, in either direction. Using limit orders and avoiding trades right at news releases can help manage it.
How do I find out which type of broker I’m dealing with?
Read the broker’s order execution policy and account descriptions. Regulated brokers generally publish how they handle orders and manage conflicts of interest. If the information is vague or missing, contact support and ask directly, or consider another provider.
