A futures company refers to an intermediary organization established according to law, which accepts the entrustment of customers, conducts futures trading for customers in its own name according to their instructions, and collects trading fees, and the trading results are borne by customers. Futures companies are the bridge between traders and futures exchanges.
Don't buy or sell, the funds are in your capital account, and the interest earned should be in your account. If you make a transaction, the deposit is transferred to the bank where the futures company opens an account, and the interest earned is the futures company's.
