这些术语均是指证券或期货交易所的经纪人。它们之间的区别在于 account executive (也称为 stockbroker，account representative) 为“业务经纪人”，其位于交易所之外，主要负责与客户打交道，接受客户的买卖指令且将此种指令传达到交易所。而floor trader或floor broker则为“场内经纪人”，指位于交易所交易庭现场，负责具体执行该客户的买卖命令的另一类经纪人。 由此，一桩证券或期货交易通常须经此两种经纪人通力合作才予以完成。

“There are two different kinds of brokers. An account executive for a brokerage firm is often called a broker. The account executive could be located in any town or city and the account executive deals with his or her customere, conveying their orders to the exchange. A second type of broker is a floor broker，a broker on the floor of the exchange who executes orders for other customers."参见季荣甫、宋雷：《法律英语教程》，法律出版社1999 年版，第369页。
