If the investor's futures counter business is closed, it may be that the investor has violated the trading or position regulations, or has not logged in for too long. Violation of the rules will be punished or the account will be frozen. If you haven't logged in for a long time, you can find a futures company to activate it.
According to domestic regulatory requirements, investors cannot directly access the exchange system, but must go through the futures company's system, that is, the counter system. Futures companies will have multiple counter systems, which are functionally divided into chairman and second-in-command systems.
