Market maker

What a market maker means

A market maker is a firm that continuously quotes two prices for the same instrument: a bid, at which it will buy, and an ask, at which it will sell. By standing ready on both sides, it gives other participants someone to trade against at almost any moment. The gap between the two quotes is the spread, and it is the market maker's basic source of revenue for providing this service.

Market makers exist on exchanges, in over-the-counter currency markets and in the CFD industry. On a stock exchange, a designated market maker may be obliged to keep quotes in a given share within agreed limits. In forex, large banks and specialist trading firms quote prices to each other and to brokers. In retail trading, the phrase is also used for brokers that take the other side of their clients' trades themselves rather than passing each order to an outside venue. This second meaning is the one most readers meet on a broker's website.

Traders meet market makers every time they click buy or sell. Even if you never see the firm's name, the price on your screen came from somewhere, and the party quoting it is acting, in effect, as a market maker.

How it works

A market maker's job is to be available, not to predict direction. The usual cycle looks like this:

1. The firm publishes a bid and an ask, based on the price it sees in the wider market plus its own margin.
2. A client buys at the ask or sells at the bid. The market maker takes the opposite position.
3. It earns the spread on a round trip of buying and selling, if it can match flows.
4. It manages the leftover exposure, called inventory, either by waiting for offsetting client orders or by hedging in the wider market.

Inventory risk is the central difficulty. If many clients buy at once, the firm ends up short and needs to cover. Market makers therefore adjust quotes, widen spreads when markets are fast or illiquid, and use hedging to keep net exposure within limits.

In the retail CFD setting, a broker acting as market maker may internalize orders. That means it keeps the client trade on its own book and may hedge only part of the net exposure. This is often described as a dealing desk model, in contrast to straight-through processing where orders are routed onward.

A worked example

These numbers are illustrative only. Suppose a market maker quotes EUR/USD at 1.0848 bid and 1.0850 ask, a spread of 2 pips.

• Client A buys 100,000 EUR at 1.0850 and pays 108,500 USD.
• Client B, a little later, sells 100,000 EUR at 1.0848 and receives 108,480 USD.
• The market maker bought from B at 1.0848 and sold to A at 1.0850. On matching amounts it keeps 0.0002 per euro, which is 100,000 x 0.0002 = 20 USD.

If only Client A had traded, the firm would be short 100,000 EUR. It would either hedge by buying euros elsewhere or carry the risk until another client trades. If EUR/USD rose before it hedged, it would lose on that open position. This is why quotes move and why spreads can widen in fast markets.

Why it matters

For a retail trader, the market maker model shapes cost and fairness. Spreads are the visible price of the service, but the structure of the relationship matters too. When a broker is your counterparty, its interests on a given trade can differ from yours. Reputable firms manage this through regulation, execution policies and transparent disclosure, but the possibility is why the topic draws scrutiny.

The model also has real benefits. Market makers provide constant liquidity, allow small order sizes that an exchange might not match, and can offer fixed or tight spreads in calm conditions. Execution can be fast because the firm does not need to find an outside seller first.

How a broker handles orders also affects slippage, requotes and behavior around news. Understanding whether a firm acts as market maker, passes orders to liquidity providers, or mixes both helps you interpret the prices you receive.

How to use it in practice

1. Read the broker's order execution policy and look for words such as dealing desk, market maker, internalization, agency, STP or ECN.
2. Check whether the firm says it may be the counterparty to your trades, and how it manages conflicts of interest.
3. Compare typical and stress-period spreads, not only the headline minimum.
4. Test execution on a demo account, then with small size, noting slippage and rejections.
5. Look at the regulator's requirements for best execution that apply to the entity serving you.
6. Keep your own records of fills so you can compare them with quotes if a dispute arises.

Common mistakes and misconceptions

• Assuming a market maker is always against you. Most client flow is balanced or hedged, and a firm earning the spread often has little reason to want clients to lose, though conflicts can exist and need controls.
• Believing market maker means manipulating prices. Prices are normally derived from external feeds, and regulated firms must follow execution rules.
• Treating no commission as no cost. Market makers often earn through the spread, so the cost is built into the quote.
• Assuming ECN or STP labels guarantee better outcomes. Marketing labels vary, and real execution quality has to be tested.
• Forgetting that the same firm can use different models for different account types or products.

Risks and limitations

Trading CFDs through any counterparty carries a high risk of rapid loss, especially with leverage. A market maker model adds counterparty risk: you depend on the firm's solvency and its fair handling of orders. Spreads can widen sharply around news, and quoted prices may not be available at size. The model is not inherently better or worse than agency routing; each has trade-offs, and rules differ by jurisdiction.

How Brokeli looks at it

In broker research we record how a firm describes its execution model, and we treat that description as a claim to be read alongside the regulator's rules and published spread data. We look at whether order handling and conflict disclosures appear in the firm's documents. Any metric we show comes from a published research snapshot, not from a single day's quotes.
