Market maker

Trader's Glossary · Order flow

Market maker

Definition. A market participant who continuously quotes buy and sell orders, providing liquidity. It earns mainly from the spread and liquidity-provision rebates.

How it works

A market maker buys at the bid and sells at the ask, trying not to hold large positions. When uncertainty rises, it widens the spread or pulls its orders.

Example

Just before an important data release, market makers pull some of their orders, making the book thinner and the spread wider.

What to watch out for

Market makers' behaviour explains many changes in liquidity, but it says nothing about market direction.

A market maker on an exchange vs a market-maker CFD broker

On an exchange, a market maker is one of many participants in the central order book. On the Warsaw Stock Exchange, “market maker” is a formal role: an investment firm, under an agreement with the exchange, must continuously quote buy and sell orders. On futures exchanges such as the CME, liquidity is provided by, among others, firms in liquidity-provider programmes that compete with one another in the same book.

At a CFD broker operating as a market maker, the broker itself is your counterparty. That's a different situation: your loss can be its revenue. I describe this in the article Why most people lose on CFDs.

What market makers look like in the order book

The DOM doesn't show who's behind an order, but market makers' behaviour can be recognised by a few traces:
