Intermediary, also known as broker. Intermediary contracts provide customers with the opportunity to conclude contracts or act as contract intermediaries. A broker is neither a party to a contract signed by a customer with a third party nor an agent of any party. According to the laws of contemporary countries, although the intermediary is a commercial activity, anyone can engage in this business freely, except the intermediary in the exchange law. The broker's main obligation is to provide an introduction for the client to conclude a contract with a third party; Its main right is to get the agreed remuneration after successful mediation.

Futures market intermediaries refer to citizens and legal persons entrusted by futures companies or customers to provide them with opportunities to conclude futures brokerage contracts or intermediary services. The futures company or the client shall pay remuneration to the broker as agreed. The significance of the existence of agents is that the results of futures trading need stronger professional traders, and most traders lack futures trading companies and related business and professional knowledge, so someone needs to introduce futures and futures companies to investors, and have professional knowledge to help customers analyze and predict the development of the market through his actions, so that investors' funds can grow as safely as possible.

The work of futures brokers can be roughly divided into two categories: 1. Find new customers and recommend futures investment to suitable investors through visits and explanations; 2. It is to analyze the market situation, predict the trend and help customers make reasonable trading strategies. These two jobs are interdependent and inseparable, because even the best level of analysis and prediction can not be reflected in the market if futures brokers do not have suitable customers. Similarly, if there are suitable customers and there is no good level of analysis and prediction, the funds of customers will not increase, and even the loss of customers will soon be lost and become fragmented. Although the two companies have some division of labor, most of them have merged into one. Therefore, the work of the intermediary is meticulous and trivial.
