ECN / STP Broker
The Formal Definition
Straight-Through Processing (STP) and Electronic Communication Network (ECN) brokers forward client orders directly to external bank liquidity pools with zero human dealing-desk intervention.
Model: Client Order → Aggregated Institutional Liquidity Pool (No Internal Dealing Desk)
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.

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.
