A floor broker is a financial professional who executes buy and sell orders on behalf of clients directly on the trading floor of a stock exchange. Floor brokers act as intermediaries between investors and the market, ensuring that orders are carried out efficiently and at the best possible price. They typically work for brokerage firms and represent institutional investors, banks, or individual traders who want to trade securities listed on the exchange.

One of the main responsibilities of a floor broker is to receive trading instructions from their clients or brokerage firms and execute those orders on the exchange floor. Using their market knowledge and experience, floor brokers try to find the best available prices for buying or selling securities. In traditional open outcry systems, they communicate with other traders and brokers through verbal bids and hand signals to complete transactions quickly.

Floor brokers also play an important role in maintaining market liquidity and smooth trading activity. By actively participating in the market, they help match buyers with sellers and contribute to efficient price discovery. Their presence on the trading floor allows them to respond quickly to changing market conditions and large trading orders.

Although electronic trading systems have reduced the number of physical trading floor participants, floor brokers still play a role in handling complex or large institutional orders. Their expertise, market access, and ability to negotiate trades remain valuable in certain markets where human judgment and direct interaction can improve trade execution.
