The second question: an enterprise can open futures accounts in multiple futures, and the futures accounts of each futures company are different. The accounts of the margin monitoring center are all in front of numbers, and each company is different. Every time a futures account is opened, an account password of the margin monitoring center will be bound. So you can't query all futures accounts of an enterprise. If the account has been closed, there are legal procedures to check and the public security organs need to cooperate. If it is not, it cannot be checked.
The third question: the center only monitors the deposit, but can't inquire all the information.
