Distinguish between ECN brokers, market makers, and hybrid models in how they execute your orders.
Where your order actually goes
When you click buy on your platform, the trade has to be filled by someone. There are two basic models for how that happens, and most brokers in 2026 are a blend of both. Understanding which model is in play tells you where the broker's incentives sit relative to yours.
ECN stands for Electronic Communications Network. An ECN broker doesn't take the other side of your trade. Instead, it routes your order to a network of liquidity providers — typically large banks, hedge funds, and other brokers — and the best available price among them fills your order. The broker earns a commission per lot for the routing service. Spreads are usually very tight because they reflect raw market liquidity. The broker has no incentive for you to lose, because they only get paid when you trade.
A market maker works differently. The market maker itself takes the other side of your trade. If you buy EUR/USD, the broker effectively sells it to you out of its own book. They quote you a price (usually with a wider, baked-in spread instead of commission), and they keep the spread as revenue. If a client wins big, the broker eats that loss. If clients lose collectively — which most retail traders do over long enough samples — the broker profits. This creates an obvious tension: the broker makes more money when its clients lose more money. Tier-1 regulators monitor for this and require disclosure.
What should you actually do with this? Read the broker's execution policy. They're legally required to publish one in tier-1 jurisdictions. Look for words like 'STP' (Straight-Through Processing), 'DMA' (Direct Market Access), 'agency model' (suggests ECN behavior), or 'principal model' (suggests market making). A hybrid broker that A-books profitable clients and discloses it openly is often a perfectly fine choice. A broker that hides its model is the red flag.
Recap: ECN routes out to liquidity providers and charges commission. Market maker takes the other side and keeps the spread. Hybrid does both. The model isn't the problem; hidden incentives are.
