Behavioral quality: having a sense of responsibility for the safety of client funds; having an understanding and concern for client transactions; having the ability to communicate friendly and patiently and meticulously; having a cheerful and optimistic attitude that makes people feel confident. A successful and excellent intermediary will not allow his clients to engage in excessive transactions, nor will he encourage his clients to take market risks that exceed their ability to bear. If a client insists on following a strategy recommended by a report or other form of advice, the intermediary should try to ascertain the source of such information to determine whether it is reliable. Successful and excellent brokers will not use half-truths and unfounded opinions as trading advice to inexperienced clients. Another more important point is that a successful and qualified intermediary must be very passionate about futures trading. He deeply understands that futures trading is the right choice for some people and the wrong choice for some people. But No matter what, futures trading will definitely bring wealth to the successful and help manufacturers and suppliers avoid risks.
