There is a saying that you admit that you are unlucky, and the futures company does not guarantee to make money. This is mentioned in the risk warning when opening an account. The point is that you trust this man too much. You don't have to interfere with his operation, but you should check your account authority regularly. Now he's lost. You can't find him and there's nothing you can do. Why don't you sue him and the company at the association? Intermediaries can't trade. He left you with no money, so don't let him hurt anyone in the future.
