Your platform shows EUR/USD with a spread of 0.1 pips, so the account looks almost free to trade. Then the statement arrives with a commission on every lot, and the total no longer matches that tiny quote. Which number is the real cost, and is the account actually cheaper than the standard one you had before?
That confusion usually comes down to three questions: how does ECN execution really work, what does an ECN account cost per lot once everything is added up, and how can you tell whether a broker genuinely offers ECN? This guide answers each of them in turn, with the numbers worked through.
An ECN forex broker routes client orders into an electronic network where prices from several liquidity providers meet, so the trader sees raw market spreads and the broker does not take the other side of the trade. Instead of widening the spread, the broker charges a fixed commission per lot, which is why the total cost has to be read as spread plus commission.

An ECN forex broker is a broker that connects its clients to an Electronic Communication Network, a system that matches buy and sell orders from many market participants automatically. Banks and other liquidity providers stream their prices into the network, and the best available bid and ask are shown to the trader with no mark-up added to the spread. The broker passes the order into that pool of prices and earns a commission for doing so, which means it is not the counterparty to the client's position and has no stake in whether the trade wins or loses.

The easiest way to see how an ECN works is to follow one order from start to finish. The example below uses EUR/USD with illustrative prices, not live quotes, and the table shows the order book that the steps refer to.
Several liquidity providers send their own bid and ask prices into the network, each with a volume attached. The highest bid and the lowest ask form the raw spread the trader sees. In the table, the best bid is 1.08500 and the best ask is 1.08502, a raw spread of 0.2 pips.
A 1-lot market buy order is filled at the best ask of 1.08502 because there is exactly 1 lot available at that level. No dealer decides whether to accept the price, so the order is matched straight away and there is no requote.
Now send a 2-lot buy order instead. The first lot fills at 1.08502, but the best ask has nothing left, so the second lot fills at the next level, 1.08504. The average fill price is 1.08503, which is 0.1 pips worse than the price on screen. That gap between the expected price and the average fill is slippage, and it grows as order size rises or depth thins out.
| Order book level | Bid price | Bid volume | Ask price | Ask volume |
|---|---|---|---|---|
| Level 1 | 1.08500 | 2 lots | 1.08502 | 1 lot |
| Level 2 | 1.08498 | 3 lots | 1.08504 | 3 lots |
| Level 3 | 1.08496 | 5 lots | 1.08506 | 5 lots |

The three broker models differ mainly in who sits on the other side of your trade and how the broker gets paid.
| Feature | ECN | Dealing Desk | STP |
|---|---|---|---|
| Counterparty | Other network participants | The broker | Liquidity provider |
| Spread type | Raw, variable | Fixed or marked-up | Variable, marked-up |
| How the broker earns | Commission per lot | Spread and client losses | Spread mark-up |
| Requotes | None | Possible | Rare |
| Conflict of interest | Low | Higher | Low |
| Suits | Active, cost-sensitive traders | Beginners, small accounts | Most retail traders |
For a retail trader, the practical difference is where the cost appears: inside a wider spread on dealing desk and STP accounts, and as a separate commission line on an ECN account.
The total trading cost on an ECN account is the raw spread converted into money plus the round-turn commission, meaning the commission charged for opening and closing the position. On 1 standard lot of EUR/USD, 1 pip is worth $10, so every spread figure can be turned into cash and compared directly.
The comparison below uses illustrative levels: a raw spread of 0.2 pips with a commission of $7 per round turn on the ECN account, against a 1.0-pip spread with no commission on a standard account. These are illustrative figures at typical market levels; for actual rates, see the Raw account and Standard account pages.
| Cost item | ECN account | Standard account |
|---|---|---|
| Spread in pips | 0.2 pips | 1.0 pip |
| Spread cost per lot | $2 | $10 |
| Round-turn commission | $7 | $0 |
| Total cost per lot | $9 | $10 |
| Monthly cost at 10 lots | $90 | $100 |
| Monthly cost at 50 lots | $450 | $500 |
In this example the ECN account saves $1 per lot, or $50 a month at 50 lots. The break-even rule follows from the table: an ECN account is cheaper only when the extra spread on the standard account, converted into money, is larger than the ECN commission. Here the gap is 0.8 pips, worth $8, against a $7 commission. If the standard spread were 0.9 pips, both accounts would cost the same. Monthly volume then decides whether the saving is large enough to justify the higher minimum deposit that ECN accounts often carry.

The label on the account page is not proof. These four checks show you where to look and what counts as a pass, although none of them is a guarantee on its own.
Search the broker on the regulator's public register, such as the FCA register in the UK. It passes when the licence number matches the broker's legal name and client money is held in segregated accounts.
Open the order execution policy document on the broker's website. It passes when it states how orders reach liquidity providers and whether the broker ever acts as counterparty.
Look at the account types page. It passes when you find a clear commission per lot alongside raw spreads, not a vague "from 0.0 pips" claim on its own.
While you are on that page, compare brokers on total cost per lot rather than headline spreads: add the round-turn commission to the average raw spread. Then check the minimum deposit and any commission tiers against your own monthly lot count.
Open the depth of market window on the trading platform. It passes when you can see several price levels with volume on both sides of the book.
Test the execution too: on a demo or a small live account, note slippage and fill speed in busy and quiet hours, and check which instruments and platforms are available on the ECN account itself, not only on the standard account.
Watch the order book fill in real time.
Test ECN execution risk-free before going live.

Whether an ECN account suits you depends on how often you trade and how far the break-even rule above works in your favour.
If you are still unsure which account suits you, try the ECN account on a demo first and check the spread and commission on your own trades, or compare it with the other account types before deciding.
Not sure which group you fall into?
Test ECN pricing on your own trades before committing funds.
Because the cost is split between spread and commission, an ECN account rewards a slightly different routine.
The pattern is easy to see on a raw-spread account over a normal trading day. EUR/USD and the other major pairs usually quote their tightest spreads while the London and New York sessions overlap, when the largest number of liquidity providers are active at the same time. As New York winds down and the Asian session opens, volume thins and spreads tend to drift wider, especially on crosses and less traded pairs. Around scheduled releases such as US non-farm payrolls or a central bank decision, quotes can widen several times over in the minutes before and after the number, then settle back once liquidity returns. Watching how the spread on your own platform moves through the day is one of the quickest ways to find the hours when your strategy is cheapest to run.
| Trading style | Typical volume | ECN fit |
|---|---|---|
| Scalping | High | Strong |
| Day trading | Medium to high | Good |
| Swing trading | Low to medium | Depends on volume |
| Beginner | Low | Weak |
ECN-style accounts are widely offered to UK retail traders, and their appeal comes from how clearly the cost can be checked under UK rules. Firms authorised by the Financial Conduct Authority (FCA) have to take reasonable steps to get the best result for clients when executing orders and have to disclose their costs, which suits a pricing model that shows the spread and the commission separately.
Raw pricing removes the hidden mark-up, but it brings its own costs and risks, and it asks a little more of the trader in day-to-day use.

Both pass orders to liquidity providers. An ECN broker matches them in a shared network with raw spreads and a separate commission, while an STP broker usually adds a mark-up to the spread instead.
They usually suit scalping, because raw spreads and no requotes lower the cost of many small trades. The benefit only holds when the spread saving per lot is larger than the commission you pay.
Yes. A fixed commission per lot replaces the spread mark-up, so the total cost is the raw spread plus the round-turn commission, and whether it is cheaper depends on the spread gap and your trading volume.
Check the regulator's register, read the order execution policy, look for a clear commission per lot on the account page and see whether the platform shows market depth on both sides of the book.
It varies by broker and is often higher than for a standard account. Check the account types page before opening, as the requirement is set by each broker.
Liquidity providers pull or widen their quotes when volatility spikes around major data. The raw spread in the order book widens until liquidity returns, which can take from a few seconds to several minutes.
You now know how an ECN broker passes orders into a network of liquidity providers, why the raw spread is only half of the cost and how to add the commission back in to see the true price of each lot. You also have four checks to test whether a broker really runs ECN execution.
In practice, the decision comes down to the break-even rule. If the spread saving per lot is larger than the commission and you trade often enough for it to add up, an ECN account is the cheaper choice; if you trade a few small positions a month, a standard account is simpler to track. Either way, read the spread as market information as well as a cost: a sudden widening tells you liquidity has left the book.
