Generally, silver transfer can only be made during trading hours, except in the morning. Basically, you can deposit and withdraw money after 8: 30. Generally, within half an hour after the end of the transaction, you can apply to the futures company for manual withdrawal, and you need to fill in the withdrawal form.

Futures companies can't directly transfer money for customers, so no futures companies do this work outside the trading period.

If you want to close your account, you need to transfer it out during trading hours, or some futures companies have the function of making an appointment to withdraw money, so you can deposit and withdraw money through this function.

The following answer, you said to close the account at 3: 30. If you have money at home and want to close your account, you can withdraw money manually. If it is late, for example, you will close your account at five o'clock. If you can't withdraw money at this time, you will usually go through the formalities of closing your account after withdrawing money the next day.

There may be a time difference between futures companies, but the principle is the same as above.
