The first question is ok. Different accounts can be traded independently, one for a long time and one for a day, without affecting each other. Opening two accounts is not in the same futures company, or opening two or more accounts in the same futures company with different names. This is what institutions do.

The second problem is to log in to an account, whether it is two accounts of the same futures company or two accounts of the same futures company, it is impossible to log in to one account and see the positions of the other account.

Each account has its own independence, and it can only be operated by logging in to this account. Login to one account can operate another account, so it will be very messy. Except for one thing, the backstage of the futures company can operate your account. Generally, when the risk factor is high, such as insufficient margin, customers will be forced to close their positions. No individual can operate another account through his own account.
