The current trading systems all have different terminal permissions. In the head office, it has the highest authority, and all customers can inquire, deposit and withdraw money and force liquidation. In the branch, you can inquire about your own customers, make deposits, and if authorized by the head office, you can also carry out compulsory liquidation.

Therefore, of course, the branch company knows the profit and loss of customers (its own customers, customers of other branches can't query).
