In order to avoid suspicion, securities and futures practitioners are not allowed to buy and sell securities and futures themselves theoretically and legally, because it is easy to get out of the rat warehouse. For example, if you help customers buy stocks, you buy some first, and then you sell them to customers at a high price, which harms the interests of customers. This is especially true for futures. If the customer wants to do more, you go first. This is the money of the black customer. As for the employees' families. . . I wonder what the law says now. Theoretically, we should avoid suspicion. Even if you can't, there are other ways. . Hehe, I wish you knew.
