ECN / STP / Market maker

Broker execution models: ECN routes orders to a liquidity network, STP routes them to a provider, and a market maker takes the other side itself.

With ECN/STP, the broker generally earns through commission and/or a small spread markup; under the market maker model, the broker's gain can coincide with the client's loss (a conflict of interest). In practice, many brokers run a hybrid model.

No model is simply good or bad; regulation, execution quality and transparency matter more. Our broker guide lists each firm's model.
