It's basically the same as the first floor. Can correspond to the same bank account. The securities capital account and the futures margin account belong to two different companies and should be separated. Securities are owned by securities companies and futures are traded by futures companies.

Options, foreign exchange and precious metals transactions are all conducted in bank accounts.

(Not to say that under a company, different businesses have to open different accounts, and the funds should be divided. )

This problem should be the problem of each company, they will separate themselves, not the funds in your account.
