An individual or firm that charges fees or commissions for executing buy-and-sell orders. A broker also refers to any firm that acts as an agent for their customer and charges a commission for its services.

As well as executing client orders, brokers may provide research, investment plans, and market intelligence to their clients. They may also cross-sell other financial products and services, such as private access to tailored solutions for high-net-worth and ultra-high-net-worth clients.
