3. Precautions During the Upgrade

To avoid the brief service fluctuations during the system upgrade affecting your trading, please make appropriate arrangements for your trades and positions in advance.

1. It is recommended that users check current positions and pending orders in advance;
2. If you have important trading plans, please try to complete related operations ahead of time;

4. After the Upgrade

After the system upgrade is completed, the platform will gradually restore all services.

Users can normally access relevant trading pages and perform trading operations. If some services experience brief delays due to system caching, node switching, or data synchronization, please wait a moment; the system will return to normal gradually.

The SunX technical team will continuously monitor the upgrade process and system operation status to ensure a smooth completion of the upgrade.

5. Risk Warning

The market may continue to fluctuate normally during the upgrade. Please manage your risks in advance.

Especially during high volatility, users are advised to control positions reasonably according to their risk tolerance and prepare trading plans ahead to avoid unnecessary risks caused by brief service fluctuations during system maintenance.
