Exchange vs. Broker

An exchange is a marketplace with rules and infrastructure for matching or otherwise facilitating trades in listed instruments. A broker provides clients with access to markets and handles services around their orders and accounts.

The Difference

When we place an order through a broker, the broker may route it to a particular exchange or another execution venue, depending on the instrument and execution model. In some markets, multiple venues can trade the same or economically similar instruments.

The distinction matters because the venue determines important market characteristics, while the broker determines how we access that market and what services, costs, and execution arrangements apply to us.

Example

We may use one broker to access a listed stock exchange. The broker provides the account and order interface, while the exchange provides the marketplace and its trading rules.

Key Terms

Exchange, broker, trading venue, order routing, market structure.
