A market maker cooks up an in-house market for its clients. Place a buy order and the broker sells to you from its own pantry; close it out and the broker buys it back. Its money is made on the spread it marks up over the raw interbank price.
Here the broker is the person across the table from you. When you win, it pays; when you lose, it keeps the plate. That is a built-in conflict of interest, the house has a reason to want your trades to fail.
None of which makes market makers crooked. The reputable ones are regulated, cannot fiddle prices, and hedge their client book out in the interbank market to cut their own risk. But the conflict is baked into the recipe, and it is worth knowing it is there.
An ECN broker sends your orders out to a pool of liquidity providers, banks, prime brokers and other big institutions. The price on your screen is the best bid and ask gathered from all of them, and when you trade you are trading against those real players, not the broker itself.
For this, the broker takes a set commission per lot, usually $3.50 to $7.00 round-trip on a standard EUR/USD lot. That commission is its entire income, win or lose, so nobody at the pass is rooting against you.
| Market Maker | ECN/STP | |
|---|---|---|
| EUR/USD spread | 0.6-2.0 pips (fixed or variable) | 0.0-0.3 pips (variable) |
| Commission | None | $3.50-$7.00 per standard lot round-trip |
| Effective spread equivalent | 0.6-2.0 pips | 0.35-1.0 pips (incl. commission) |
| Conflict of interest | Yes, broker is counterparty | No, broker earns commission only |
| Requotes | Possible during news | Rare, orders go to market |
| Depth of Market | Not shown | Usually available |
| Best for | Beginners, low-frequency traders | Active traders, scalpers, EAs |

An ECN broker passes your orders directly to liquidity providers without acting as your counterparty. You get real market prices, usually 0.0-0.3 pips on EUR/USD, plus a commission per lot. The broker earns the same commission whether you win or lose.
A market maker sets its own bid and ask prices and acts as the counterparty to your trades. It earns money from the spread markup. Regulated market makers are a legitimate and common model, just be aware of the structural conflict of interest.
For frequent traders, ECN is usually cheaper. For occasional traders on small positions, a market maker with a 0.8-pip spread can be just as cost-effective without the commission complexity. Calculate the total cost for your specific trading volume.
