ECN vs STP Brokers: What Is the Difference?

When choosing a forex broker, you'll often come across two terms: ECN (Electronic Communication Network) and STP (Straight Through Processing). Both are considered "No Dealing Desk" (NDD) brokers — meaning they don't take the opposite side of your trades. But they differ in how your orders are executed and priced.

Understanding the difference between ECN and STP brokers can directly impact your trading costs and execution quality.

What Is an ECN Broker?

An ECN broker connects traders directly to a network of liquidity providers — banks, hedge funds, and other large financial institutions. Orders are matched electronically within this network, often resulting in very tight spreads that can go as low as 0.0 pips on major pairs.

Key characteristics of ECN brokers:

• Spreads start from 0.0 pips — raw interbank pricing
• A fixed commission per lot is charged (typically $3–$7 per side)
• Orders are filled at the best available price from multiple liquidity providers
• No conflict of interest — the broker profits from commissions, not trader losses
• Suitable for scalpers, high-frequency traders, and algorithmic trading

What Is an STP Broker?

An STP broker (Straight Through Processing) routes your orders directly to one or more liquidity providers without manual intervention from a dealing desk. Unlike ECN, STP brokers may work with a limited pool of liquidity providers and add a markup to the spread instead of charging a separate commission.

Key characteristics of STP brokers:

• Spreads typically start from 0.5–1.0 pips (includes broker markup)
• No separate commission — cost is embedded in the spread
• Orders are sent straight to liquidity providers
• Some STP brokers offer variable spreads; others offer fixed
• Suitable for retail traders who prefer simpler cost structures

ECN vs STP: Side-by-Side Comparison

How to Calculate Total Trading Cost

To compare ECN vs STP costs fairly, you need to calculate the all-in cost — not just the spread.

ECN example:

• Spread: 0.1 pips + Commission: $6 per standard lot round-trip
• Total cost per lot: $1 (spread) + $6 (commission) = $7

STP example:

• Spread: 1.2 pips, no commission
• Total cost per lot: $12

In this scenario, the ECN broker is cheaper for standard lot traders — but for micro-lot traders, the fixed commission may make the STP option more economical.

Which Is Better: ECN or STP?

• Choose ECN if you are a scalper, day trader, or algorithmic trader who executes high volumes and needs the tightest possible spreads.
• Choose STP if you prefer a simpler cost structure with no commissions, or if you trade with smaller position sizes.
• Both ECN and STP are preferable to market makers for traders who prioritize transparency and no conflict of interest.

A Note on Broker Claims

Many brokers market themselves as "ECN" without truly being one. A real ECN broker will show you depth of market (DOM) — a live view of available buy and sell orders at different price levels. If a broker claims to be ECN but doesn't offer this feature, treat the claim with skepticism.
