Legal analysis: in the trial of futures disputes, according to the principle of "whoever claims it, he will give evidence", but if the client claims that the brokerage company has not traded in the market and the brokerage company denies it, the brokerage company will bear the burden of proof.

Legal basis: Article 64 of the Civil Procedure Law of People's Republic of China (PRC) stipulates that the parties have the responsibility to provide evidence for their claims. The people's court shall investigate and collect evidence that the parties and their agents ad litem cannot collect on their own due to objective reasons, or evidence that the people's court considers necessary for hearing a case. The people's court shall comprehensively and objectively examine and verify the evidence in accordance with legal procedures.
