Yes, some futures companies can't see it with the settlement shielding server. The server of futures company is very expensive, and the maintenance cost of firewall is very high. Endure the malicious attacks of hackers. I have seen a futures company in Shandong, and I can't even get on the trading hours after the Chinese New Year. It's crazy that the headquarters is not willing to spend money to maintain it. Block many websites. You can't continue without trading time.
