Article 10 of the Supreme People's Court's Provisions on Several Issues Concerning the Trial of Futures Dispute Cases stipulates that if a citizen or legal person is entrusted by a futures company or a customer to provide intermediary services for him to sign or conclude a futures brokerage contract, the futures company or the customer shall pay remuneration to the intermediary in accordance with the agreement. The intermediary shall independently bear the civil liability arising from the intermediary brokerage relationship. So the answer to this question is BCD.
