Dear Users,

To further improve platform performance and the trading experience, SUNX will perform a system upgrade on December 21, from 05:00 to 06:00 (UTC+8), lasting approximately 1 hour. Trading operations will be temporarily unavailable during maintenance. Please manage your positions and arrange your trading in advance.

1. Maintenance Time

• Maintenance Window: December 21, 05:00–06:00 (UTC+8)
• Estimated Duration: Approximately 1 hour

2. Service Impact During Maintenance

Access to the official website does not mean that trading operations are available. Please monitor service availability and the actual status of your orders during maintenance.

3. User Reminders

1. Manage positions in advance: Before maintenance, review your positions, margin, and orders, and arrange any necessary actions.
2. Plan trading ahead: Allow sufficient time for important trading activities and avoid operating during maintenance.
3. Avoid duplicate submissions: If trading operations are unavailable or pages respond abnormally, do not repeatedly submit identical requests.
4. Verify results after restoration: After maintenance, promptly check your account data, positions, orders, and trade history.
5. Report issues promptly: If abnormalities persist after services resume, contact SUNX through its official customer support channels for verification and assistance.

4. Service Restoration and Risk Notice

After maintenance is completed, the platform will restore trading services and normal data display. Please refer to the actual service status.

Market prices may continue to fluctuate during maintenance. The temporary unavailability of trading operations may affect your ability to adjust positions. Please manage risks in advance based on your positions and risk tolerance.

We apologize for any inconvenience. Thank you for your understanding and support of SUNX.
