Is there an agreement between you? If the other party is an investment and wealth management company, a contract agreement is required. This is a guarantee. If you do it yourself, there is nothing you can do. Then it is possible for the other party to use your funds for high-frequency trading and earn commissions. I don't care about your profit or loss at all. In short, there must be evidence. Evidence in your favor, and then solve it through legal means. I hope my answer is satisfactory.
