Most traders think they understand their broker. Then one day, a position slips badly on a calm market, or a spread doubles right before news, and they start asking uncomfortable questions. The question usually lands here: is my broker actually filling my order in the market, or are they taking the other side of my trade themselves?

That distinction separates two fundamentally different broker models. An ECN — Electronic Communications Network — routes your order to a pool of liquidity providers: banks, institutions, other traders. Your broker earns a flat commission per lot. A market maker, by contrast, creates an internal market. They quote you a price, take your trade onto their own book, and profit from the spread between the buy and sell price.

CONCEPTECN brokers earn commissions routing real orders; market makers earn by being your counterparty and capturing the spread.
WARNINGA market maker profits when you lose — that structural conflict of interest shapes every spread they quote you.
KEY IDEANeither model is automatically superior — costs, execution speed, and minimum deposits differ significantly between them.

Here is a concrete example. Say you are trading the AUD/USD. An ECN broker might show a raw spread of 0.1 pips and charge $7 commission per standard lot. Your total round-trip cost on a $100,000 position is $14. A market maker might show zero commission but widen the spread to 1.5 pips — that same trade costs you roughly $15, and the broker pockets the difference regardless of whether your trade wins or loses.

The deeper mechanical difference is conflict of interest. When a market maker hedges your trade externally, the conflict reduces. Many do hedge most positions. But when they do not, they benefit directly from your loss. ECN models remove that conflict — the broker earns the same flat fee whether you win or lose. Algorithmic and high-frequency traders strongly favour ECN execution for this reason.

Know your broker's model before you trade a single lot. The cost structure is not hidden — it is just rarely explained clearly until it shows up in your results.
