An Introducing Broker (IB) is a financial professional or firm that introduces clients to a broker, dealer or market maker. The introducing broker typically maintains a relationship with the clients and provides them with support and guidance, while the executing broker actually executes the trades. The IB receives a commission or other compensation for the clients it introduces to the executing broker. Introducing brokers can provide a valuable service to traders by helping them navigate the complex world of financial markets and connecting them with the right broker for their needs.
