ECN vs STP vs Market Maker: How Broker Type Affects Your Spreads

Every forex broker processes your trades using one of three execution models: ECN, STP, or Market Maker. Each model determines how your orders are filled, what spreads you pay, and whether the broker has a financial incentive to trade against you.

This matters because the execution model directly affects your trading costs. An ECN broker aggregates pricing from 20+ liquidity sources and passes through the tightest available spread. A market maker sets its own prices and may profit when you lose. An STP broker sits somewhere in between.

But the reality is more nuanced than "ECN good, Market Maker bad." Some of the cheapest and most reliable brokers in the world use market-making models. And some self-proclaimed "ECN" brokers offer worse execution than their market-maker competitors. What matters is the specific broker's implementation, not the label.

What Is an ECN Broker?

ECN stands for Electronic Communication Network. An ECN broker connects your orders to a network of liquidity providers: banks (JPMorgan, Deutsche Bank, Barclays), non-bank market makers (Citadel, XTX Markets), hedge funds, and other brokers. When you place an order, it enters the ECN's order book and is matched against the best available price from all connected participants.

The key characteristics of a true ECN model:

• Market depth: You can see the order book with multiple price levels and available volume at each level. This is sometimes called Level II or Depth of Market (DOM) data.
• Variable spreads: Spreads fluctuate in real-time based on supply and demand in the network. During high liquidity (London session), spreads can reach 0.0 pips. During low liquidity (Asian session or rollover), they widen.
• Commission-based pricing: The broker charges a fixed commission per lot instead of marking up the spread. Typical commission: $3.00-$3.50 per lot per side.
• No conflict of interest: The broker does not take the other side of your trade. They profit only from commission, regardless of whether you win or lose.
• Price improvement possible: Your limit orders can be filled at prices better than your specified level if the ECN network has a better price available.

ECN Broker Examples

IC Markets is the most widely cited ECN broker. Their Raw Spread account connects to over 25 liquidity providers via Equinix data centers. Average EUR/USD spread is 0.08 pips with a $3.50 per side commission. IC Markets shows full Depth of Market on their cTrader platform, allowing traders to see pending orders at multiple price levels.

Pepperstone operates an ECN model on their Razor account. They connect to multiple tier-1 banks and non-bank liquidity providers. Average EUR/USD spread is 0.17 pips with $3.50 per side commission. Pepperstone also shows Depth of Market on cTrader.

LMAX Exchange is a pure institutional ECN that also serves retail clients. They operate as a regulated exchange (rather than a broker), meaning they match orders in a central order book. Spreads are extremely tight (0.0-0.1 pips on EUR/USD), but minimum deposits are typically $1,000+ and the platform interface is designed for professionals.

What Is an STP Broker?

STP stands for Straight Through Processing. An STP broker routes your orders directly to one or more liquidity providers without manual intervention. The key difference from ECN is that STP does not use a multi-participant order book. Instead, the broker selects the best available price from its liquidity providers and fills your order at that price (or adds a small markup).

Key characteristics of STP:

• No dealing desk: Orders are processed automatically without human intervention. This eliminates requotes and deliberate delay.
• Best-price aggregation: The broker's technology polls multiple liquidity providers and fills you at the best available price. However, you cannot see the full order book like with ECN.
• Spread or commission pricing: Some STP brokers embed their profit in the spread (wider spread, no commission). Others charge a commission on raw spread, similar to ECN.
• Limited conflict of interest: STP brokers do not internalize orders as a standard practice, though some may hedge or warehouse certain order flow.

STP Broker Examples

FP Markets uses an STP model with routing to multiple liquidity providers via a Straight Through Processing bridge. Their Raw account offers average EUR/USD spreads of 0.1 pips with a $3.00 per side commission.

Tickmill operates an STP/NDD (No Dealing Desk) model. Orders are routed to institutional liquidity providers without broker intervention. Their Pro account averages 0.1 pips on EUR/USD with a $2.00 per side commission, making them one of the cheapest STP brokers available.

What Is a Market Maker Broker?

A market maker broker takes the opposite side of your trades. When you buy EUR/USD, the broker sells it to you from their own inventory. When you sell, the broker buys from you. The broker sets the bid and ask prices (the spread) and profits from the difference.

This creates a theoretical conflict of interest: if you lose money, the broker keeps your loss as profit. If you win money, the broker loses. This is why market makers have a reputation problem in the forex industry.

However, the reality at large, regulated market makers is more complex:

• Risk management via hedging: Large market makers do not simply bet against every client. They aggregate client order flow and hedge their net exposure with institutional counterparties. If 60% of clients are long EUR/USD and 40% are short, the broker only needs to hedge the 20% imbalance externally.
• Revenue from spread, not losses: Well-run market makers profit primarily from the bid-ask spread, not from client losses. Their business model works even when clients are consistently profitable, because the spread revenue exceeds hedging costs.
• Regulatory oversight: FCA, ASIC, and CySEC require market makers to demonstrate fair pricing and execution. Regular audits check that client orders are filled at or near the quoted price without artificial manipulation.
• Fixed or semi-fixed spreads: Market makers can offer more predictable spreads because they control the pricing. Some offer fixed spreads that do not widen during volatility, which is not possible in a pure ECN model.

Market Maker Broker Examples

Exness operates a market-making model on their Standard and Zero accounts. They internalize a large portion of order flow and hedge the remainder. Despite being a market maker, Exness offers some of the tightest spreads in the industry: 0.6 pips on EUR/USD Standard, 0.0 pips on Zero. Their scale (one of the world's largest brokers by volume) gives them deep internal liquidity to offer competitive pricing.

XM is a market maker with CySEC and ASIC regulation. Their Ultra Low account offers 0.6 pip EUR/USD spreads with no commission, competitive with raw ECN accounts at other brokers. XM also offers a $30 no-deposit bonus and $5 minimum deposit, making them accessible to beginning traders.

IG Group is one of the oldest and largest market makers, publicly traded on the London Stock Exchange. Their Standard account offers 0.6 pip EUR/USD spreads. IG's size and public listing provide additional transparency: their financial statements show exactly how much they earn from client spread and how they manage risk.

How Execution Model Affects Your Spreads

The execution model influences spread in two ways: the base spread (how tight the pricing is) and the spread behavior during volatility (how much it widens during news events).

Base Spread

ECN brokers generally offer the tightest base spreads because they aggregate pricing from the most sources. However, large market makers can match or beat ECN spreads on popular instruments because their internal flow provides self-liquidity.

To illustrate: IC Markets (ECN) averages 0.08 pips on EUR/USD. Exness (Market Maker) averages 0.0 pips on the same pair with their Zero account. The market maker is actually cheaper here because Exness's volume allows them to price at zero and recover costs through commission.

The generalization that "ECN equals lowest spreads" is not always true in practice.

Spread Behavior During Volatility

This is where execution models diverge more clearly. ECN spreads are purely market-driven: when liquidity evaporates (during NFP, FOMC, or CPI releases), ECN spreads widen dramatically because the liquidity providers withdraw their quotes. There is no buffer.

Market makers have more control. They can choose to absorb short-term volatility and maintain tighter spreads during events, knowing that the spike is temporary. However, they can also choose to widen spreads aggressively. The behavior depends on the specific broker's risk management philosophy.

In our testing during March 2026 NFP:

Interesting patterns emerge. XM (market maker) showed the least proportional widening (6x) because their standard account spread starts wider but does not blow out as dramatically. IC Markets (ECN) showed the most aggressive widening (50x) because their ultra-tight normal spread has the farthest to go when liquidity disappears.

In absolute terms, however, Exness peaked at 2.5 pips ($25 per lot) while XM peaked at 5.0 pips ($50 per lot). Even though XM's proportional widening was smaller, the actual peak cost was higher because they start from a wider base.

The Hybrid Model: How Most Brokers Actually Work

The clean categories of ECN, STP, and Market Maker are useful for education but do not reflect how most modern brokers operate. The majority of large brokers use a hybrid model:

1. Internalization first: The broker attempts to match client orders internally. If one client is buying EUR/USD and another is selling, the broker matches them without going to external liquidity. This is technically market-making but is the most efficient execution possible (lowest latency, zero spread cost to the broker).
2. External routing second: Orders that cannot be matched internally are routed to external liquidity providers via STP or ECN connections. This handles the imbalance between buy and sell orders.
3. Risk management layer: The broker's risk engine continuously monitors net exposure and hedges positions that exceed predefined thresholds. This protects both the broker and clients from extreme market moves.

Exness, IC Markets, and Pepperstone all use some form of hybrid model, despite marketing themselves differently. The regulatory requirement is that clients receive fair execution regardless of the internal routing. FCA, ASIC, and CySEC auditors specifically test for this by analyzing fill quality, slippage distributions, and reject rates across different client segments.

Which Model Should You Choose?

The execution model is less important than the broker's actual cost and execution quality. Here is our framework for choosing:

Choose ECN If:

• You are a scalper who needs the absolute tightest spreads and fastest execution.
• You want to see market depth (Depth of Market / Level II data) to gauge institutional order flow.
• You use cTrader, which is designed for ECN trading with full DOM support.
• You trade large position sizes (5+ lots per trade) where spread savings are amplified.
• You run algorithmic strategies that need direct market access.

Best ECN brokers: IC Markets (0.08 pips, $7 RT), Pepperstone (0.17 pips, $7 RT).

Choose STP If:

• You want no dealing desk execution but do not need full market depth.
• You prefer lower commission over the absolute tightest spread.
• You trade medium volume (10-50 lots per month) and want a clean execution model.

Best STP brokers: FP Markets (0.1 pips, $6 RT), Tickmill (0.1 pips, $4 RT).

Choose Market Maker If:

• You are a beginner who wants simplicity (one cost, no commission).
• You trade at a well-regulated market maker with a proven track record.
• You want fixed or semi-fixed spreads that do not widen dramatically during news.
• You need a low minimum deposit ($5-$10).
• You want instant withdrawals (market makers like Exness process withdrawals faster because they hold client funds internally).

Best market maker brokers: Exness (0.0-0.6 pips depending on account), XM (0.6-0.8 pips).

Debunking Common Myths

Myth: "Market makers trade against you"

Partially true at a technical level, completely misleading at a practical level. Yes, the broker is on the other side of your trade. But regulated market makers are required to quote fair prices derived from real market data. They cannot simply give you a bad price and pocket the difference. CySEC and FCA actively audit execution quality, and brokers that manipulate prices face license revocation.

The more accurate statement is: market makers take the other side of your trade but manage their risk through hedging and diversification, profiting from the spread rather than from your losses.

Myth: "Only ECN brokers offer 0.0 pip spreads"

False. Exness is a market maker and offers guaranteed 0.0 pip spreads on their Zero account for 95% of the trading day. Their scale allows them to absorb the cost of zero-spread pricing and recover it through commission. Market makers with sufficient volume can offer pricing as tight as or tighter than ECN networks.

Myth: "ECN brokers never have conflicts of interest"

Partially false. ECN brokers do not take the opposite side of your trades, but they do have a volume incentive. The more you trade, the more commission they earn. This can lead to aggressive marketing that encourages overtrading. While there is no direct price manipulation incentive, the commission model is not entirely conflict-free.

Myth: "STP is safer than market making"

The safety of a broker depends on its regulation, not its execution model. An STP broker regulated in Belize (no meaningful oversight) is far riskier than a market maker regulated by the FCA (UK) or ASIC (Australia). Always prioritize regulation over execution model labels.

Real-World Cost Comparison by Model

Let us compare the actual trading cost for 100 standard lots of EUR/USD at the best broker in each category:

The cheapest option is Tickmill's STP Pro account at $5.00 per lot, followed by Exness Standard at $6.00 per lot. IC Markets' ECN account comes in at $7.80 per lot. The execution model label does not predict cost ranking.

The practical lesson: stop choosing brokers based on whether they are "ECN" or "Market Maker." Choose based on total cost per lot, execution quality (speed, slippage), regulation, and withdrawal reliability. Those are the metrics that affect your actual trading results.

How to Verify Your Broker's Execution Model

Many brokers claim to be "ECN" but actually operate hybrid or STP models. Here is how to verify:

1. Check for Depth of Market (DOM): True ECN brokers show multiple price levels with volume at each level on cTrader or MT5 DOM. If your broker does not display DOM data, they are likely STP or market maker.
2. Test for negative balance risk: ECN/STP brokers that route to external LPs may expose you to negative balance situations during extreme volatility (though most regulated brokers now offer negative balance protection regardless of model).
3. Analyze your fill reports: ECN fills show price improvement on limit orders (you get a better price than you requested). Market maker fills are typically at the exact quoted price. Check your MT5 trade history for fill prices versus requested prices.
4. Check during rollover: ECN spreads widen dramatically during the daily rollover (21:00-22:00 UTC). Market makers may maintain tighter rollover spreads. Wide rollover spreads suggest genuine market access.
5. Read the regulatory filing: FCA and CySEC regulated brokers publish execution quality reports (RTS 28 reports under MiFID II). These reports detail what percentage of orders are internalized vs routed externally. This is the definitive source.

Which Brokers Are ECN, STP, and Market Maker?

Here is a factual classification based on regulatory filings and published execution policies:

Note that most brokers use hybrid models regardless of how they market themselves. The classification above reflects their primary execution approach, not the sole method they use.
