You can log in to your account on weekdays, including weekday evenings. But you can't log in on Saturday and Sunday.
Non-trading time futures accounts cannot be logged in at any time. At present, the trading software used by most investors belongs to the mainstream CTP system. For data security, futures companies need to initialize and restart this system every day, with a transition time.
Therefore, before the system is turned on, investors can't use their futures trading accounts to log in to the futures trading software.
