Cole Barrett's Reality Check

The Unvarnished Bottom Line

"An ECN broker doesn't care whether you make money or lose money—they make their margin entirely on clear execution volume and ticket fees. If you want transparent execution, you want an agency model."

How Brokers Weaponize This Term

Some brokers market themselves as 'hybrid ECN' operators to attract experienced traders, but route profitable orders to external pools while routing losing or amateur flow to an internal B-Book to capture their losses.

Frequently Asked Questions

Why do ECN brokers charge separate commissions?

Because true ECN brokers pass along raw interbank spreads with zero built-in markup, charging an explicit commission per lot to monetize order routing.

What is the key difference between ECN and STP?

STP passes orders straight to liquidity providers, while an ECN provides an open order book where your orders can interact directly with bids and offers from other network participants.
