STP vs ECN: Which Forex Account Type Fits You?
STP and ECN both mean your broker has no dealing desk standing against your trade, but they get your order to the market in different ways. An STP broker passes your order on to its own set of liquidity providers and usually earns its money from a markup on the spread. An ECN-style account puts your order into a shared pool of quotes and usually charges a separate commission on top of a raw spread. Neither is better in the abstract. Which one costs you less depends on how many lots you trade, how tight your entries are and how much you value seeing the order book.
This guide explains both models in plain terms, compares them on the things that change your results, works through a cost example, and shows what to check before you believe any broker’s label.
TL;DR
- STP means orders are routed automatically to external liquidity providers, with no internal dealing desk. Pricing is typically a spread with a built-in markup.
- ECN means orders interact with quotes from multiple participants in a network. Pricing is typically a raw spread plus a per-lot commission.
- Low-volume traders often find all-in spread pricing simpler. Scalpers and high-volume traders often compare commission pricing first, because the raw spread can be tighter.
- Labels are not guarantees. Compare total cost per lot, execution speed, slippage behavior and regulation, not the acronym.
- Our own pricing is published on the accounts page, so you can run the numbers yourself.

What STP means in forex
STP stands for straight-through processing. In practice, an STP broker is an intermediary that sends client orders to outside liquidity sources, such as banks, non-bank market makers or an aggregated feed, instead of filling them on an internal dealing desk, as one explainer on STP brokers puts it.
The typical path looks like this:
- Liquidity providers stream prices to the broker.
- The broker aggregates those prices and shows you one composite bid and ask.
- You click buy or sell, and the broker’s system automatically routes the order to the provider offering the relevant best price.
- The provider fills the order and confirms it back through the chain.
The important point is that you see the broker’s blended price, not each provider’s quote. Brokers using this model commonly add a fixed markup to the wholesale spread. One example published online uses a 0.8-pip markup, though the figure differs from broker to broker.
That is why STP pricing feels simple: the cost is inside the spread you see. There is usually no separate commission line.
What ECN means in forex
An ECN is an electronic communication network. It is a computerized system that displays bids and asks from multiple market participants and automatically matches buy and sell orders, according to Investopedia’s definition. In forex, that means you see the best available quotes from the network, and your order is matched electronically against the participants willing to trade at that price.
Two features follow from this design:
- Raw pricing. Because quotes come straight from the network, the spread is not padded by the broker. The broker earns through a commission instead.
- Visible depth. Many ECN-style setups let you see more than the top-of-book price, and you can post limit orders that add liquidity.
For US readers, note that the word has a formal meaning in equities regulation: ECNs must continuously disseminate price information, manage a limit book or ongoing auctions, and automatically match and execute customer orders. In retail forex marketing, “ECN” is used far more loosely, which is the reason to look past the label.
STP vs ECN: the real differences
The two models are not opposites. An ECN generally routes orders into a shared venue where participants’ orders are matched in a central book. An STP broker routes to its own set of liquidity providers, which may quote bilaterally. Real-world brokers can combine both types of liquidity, so a single account can be part STP and part ECN in how it sources prices.
| Feature | STP | ECN |
|---|---|---|
| Order routing | Automatically sent to the broker’s chosen liquidity providers | Placed into a network where participants’ quotes and orders interact |
| Price you see | Aggregated bid/ask, often with a markup | Raw best bid/ask from the network, often with visible depth |
| Typical cost structure | Wider spread, usually no commission | Tighter spread plus commission per lot |
| Transparency | Good on conflicts of interest, limited on depth | Higher, with order book visibility on some platforms |
| Can you add liquidity with limit orders? | Usually not as a visible quote | Often yes |
| Best suited to | Simple, predictable costs; lower volume | Scalping, high volume, cost-sensitive strategies |
| Main risk to watch | Markup size, slippage in fast markets | Commission eating a thin edge, thin depth at news time |
Two more points the table cannot show.
Both can be “no dealing desk.” The older dividing line was market maker versus agency model. Both STP and ECN sit on the agency side, which means the broker does not need you to lose in order to profit. Its revenue comes from markups, commissions and volume.
Neither removes market risk. Slippage, spread widening during news and requotes can happen on either model, because they come from the market itself and not only from the broker’s setup.
How the market behind the label works
It helps to know what both models connect to. The spot FX market is fragmented: participants can connect to more than 75 different FX trading venues. The same paper estimates that execution algorithms account for 10 to 20% of daily global spot FX trading, roughly USD 200 to 400 billion a day, and can aggregate data across those separate liquidity pools.
That matters for you in a simple way. Whichever label a broker uses, the quality of your fill depends on two things: how deep and stable the underlying liquidity is, and how good the broker’s routing and aggregation technology is. A broker with an ECN badge and shallow liquidity can fill you worse than an STP broker with strong providers and fast routing.
Costs: spread markup vs commission
This is where most traders should spend their time. The two pricing styles reach the same place by different roads, so compare them as a total cost per lot.
A worked example
Take EUR/USD, where one pip on a standard lot (100,000 units) is worth about $10. This is an illustration, not a quote from any broker.
- Markup-style account. Wholesale spread 0.1 pip, plus a 1.0 pip markup. Total about 1.1 pips, or about $11 per lot.
- Commission-style account. Raw spread 0.1 pip, plus a commission of $7 per lot. Total about 0.1 pip ($1) plus $7, or about $8 per lot.
On these numbers, the commission account is cheaper by about $3 per lot. At 5 lots a month, that is $15, which most people will not notice. At 200 lots a month, it is $600. A scalper placing dozens of trades a day feels it immediately.
The example flips if the raw spread on the commission account is wider than you assumed, which happens in quiet sessions or on less liquid pairs. So test your actual pair at your actual trading hours. Our guide to forex trading costs covers spreads, commissions and swaps in more detail, and the raw spread vs standard account comparison walks through the break-even point.
Slippage and speed
Cost is not only the spread. If your order fills a fraction of a pip away from the price you clicked, that is slippage, and it can swamp a small commission difference. Fast infrastructure reduces the gap between click and fill. Our piece on low latency trading explains what speed really means for retail traders, and understanding limit vs market orders helps you control slippage no matter which model you use.
Which account suits which trader
Beginners and occasional traders. A single all-in price is easy to read. You can see the cost before you click and there is no commission arithmetic. STP-style pricing fits well here.
Swing and position traders. Holding for days means swaps and wider stops matter more than a fraction of a pip at entry. Simplicity usually wins.
Scalpers. When your target is a few pips, a tight raw spread plus a known commission is easier to model than a markup. Execution speed and consistency matter as much as the price. Our guide to real ECN-style brokers and what they cost shows what to look for.
Algorithmic and EA traders. Strategies that trade often need predictable costs per trade and fast fills. A commission model is easier to backtest because the cost per lot is fixed.
Crypto CFD traders. Crypto markets trade around the clock and move fast, and liquidity can thin out at weekends. Compare the spread and fill quality on the specific coin pair you trade, at the hours you trade. Do not assume forex pricing carries over to crypto.
How to check a broker’s claims
Anyone can write “ECN” or “STP” on a website. Before funding an account, check the following.
- Regulation. In the US, off-exchange retail forex dealing is restricted: only certain registered futures commission merchants and retail foreign exchange dealers may act as counterparties to retail customers. Rules differ by country, so check the regulator that covers your location and the entity you actually sign with.
- Total cost per lot. Add spread, markup and commission for your instrument. Ignore the headline “from” spread.
- Spread at your trading hours. Open a demo and watch the quote during your session, including around data releases.
- Execution evidence. Look for published average execution speeds and test with small live trades.
- Withdrawals. Ask how fast and how easy they are. A broker confident in its model makes this simple.
- Platform. MetaTrader 5 is common across the industry, so confirm charting, order types and automation support.
When you see rankings of the “best STP brokers”, treat them as a starting list and not a verdict. Most are affiliate-driven. Your own cost and fill tests matter more.
Our view on STP vs ECN
We built Mitra Markets around one idea: retail traders should not be denied the speed and tools usually kept for professionals. That is why we focus less on which acronym a model carries and more on what you actually get at the point of execution.
Our MitraNet™ technology is designed for execution under 30 milliseconds, with direct access to Tier-1 liquidity. In our view, that is what shapes your fill: the quality of the liquidity behind the price and the speed of the route to it. A label alone says little about either.
We also believe pricing should be readable. Our published fees include a $7 per lot commission and a 1.0 pip markup option, so you can compare your own cost per lot before you commit. There is no minimum deposit, deposits are instant, and we aim to keep bureaucracy out of your way.
If you scalp, run algorithms or trade crypto CFDs, that combination of tight pricing and fast execution is what we designed for. Run the numbers on your own volume and pick the structure that makes your strategy cheaper.

Trade with institutional-grade conditions
If you want to test these ideas with real numbers, our Edge and Standard accounts let you compare a commission-based structure with a markup-based one. You can trade forex, commodities, indices and crypto CFDs across our markets, with MetaTrader 5 compatibility, advanced charting and algorithmic trading support. There is no minimum deposit, and deposits are instant.
Start with a small position size, measure your fills against the quotes, and scale up only when the cost and speed match what you modeled. Our accounts page lists the current fees.
FAQ
Is ECN better than STP?
Not automatically. ECN-style pricing tends to win for high-volume traders and scalpers, because a tight raw spread plus a fixed commission can cost less per lot. STP-style pricing is often simpler and can be cheaper for lower volumes. Compare the total cost per lot on your own instrument.
Is an STP broker a market maker?
No. A market maker fills your order on its own dealing desk and can take the other side of your trade. An STP broker routes your order to outside liquidity providers. Because brokers can mix models, check how a specific broker describes its execution.
Do ECN accounts always have lower spreads?
They usually show tighter raw spreads, but you pay commission on top. The all-in cost can end up close to, or higher than, a markup account if the raw spread widens in quiet sessions or on less liquid pairs. Test at the hours you trade.
Can STP and ECN be combined?
Yes. Real-world brokers can source liquidity from both venue-style networks and bilateral providers. That is why the acronym alone tells you little, and why execution speed, depth and total cost are better tests.
Which should a scalper choose?
Most scalpers start with a commission-based raw spread account, because the cost per trade is fixed and easy to model. Just as important is fast, consistent execution, since slippage can erase a small edge. Measure fills with small live trades before scaling up.
