Legal analysis: When dealing with the infringement dispute of futures trading, the people's court should carefully examine whether there is a causal relationship between the infringement and the loss, and whether the actor is at fault, and should accurately determine the civil liability of the parties according to the size of the fault.

The party at fault shall be liable for the losses of the party without fault; If both parties are at fault, they shall bear corresponding responsibilities.

In addition, brokers should separate the customer's deposit from their own funds for special purposes. Whoever misappropriates the customer's deposit shall compensate the customer.

Legal basis: Article 165 of the Civil Code of People's Republic of China (PRC). If the actor infringes upon the civil rights and interests of others through fault, he shall bear the tort liability. If the actor is presumed to be at fault according to the law and cannot prove that he is not at fault, he shall bear tort liability.
