commission paid to a broker who buys and sells securities. Fees vary depending on whether a full-service broker (e.g., one that provides recommendation reports) or a discount broker (e.g., one that just executes orders) is used.An example of a full-service broker is Prudential-Bache Securities. An example of a discount broker is Charles Schwab & Co. Fees also vary within each category so one full-service broker may charge you a different commission rate than another. Brokerage fees may depend on the market price per share and the number of shares traded.
