【System Upgrade】Service Upgrade Completed and Upcoming Maintenance Arrangements

Dear Users,

SUNX has successfully completed this system service upgrade. The upgrade process took approximately 4 minutes, and all trading services on the platform have now returned to normal. Thank you for your understanding and support during the upgrade.

To further improve system stability, trading performance, and service quality, SUNX plans to perform a database and system version upgrade at 07:00 on August 28, 2026 (UTC+8), optimizing the backend database and core system services. Details are provided below.

I. Upcoming Upgrade Schedule

• Upgrade time: August 28, 2026, at 07:00 (UTC+8)
• Estimated service impact duration: Approximately 10 seconds

This upgrade is expected to cause a brief service impact lasting approximately 10 seconds. The actual duration will depend on the progress of the upgrade.

II. Impact on Trading Services

Certain trading functions may experience brief disruptions during the upgrade, including:

1. Contract trading: Order placement may fail;
2. Spot trading: Order placement may fail;
3. Options trading: Order placement may fail;
4. Trading requests: Some requests may be briefly delayed or unable to be submitted.

Please arrange related trading activities in advance and monitor order status and actual execution results during the upgrade.

III. Deposits, Withdrawals, and Frozen Funds

Deposits and withdrawals will not be affected during this database and system version upgrade and will remain available as normal.

Any related orders or trading funds frozen due to the brief system upgrade will be automatically unfrozen in accordance with the platform’s system rules after services are restored. No additional action is required from users.

IV. User Instructions

1. Check your account in advance: Before the upgrade, review your positions, open orders, and margin, and plan your trading activities appropriately.
2. Avoid duplicate orders: If order placement fails or page responses are delayed, first verify order status and avoid repeatedly submitting the same order within a short period.
3. Wait for service restoration: If you confirm that trading operations cannot be performed normally, wait until the upgrade is completed and services are restored before proceeding.
4. Verify execution results: All trading services will automatically return to normal after the system upgrade. Promptly check your orders, execution records, and fund status.
5. Report issues promptly: If abnormalities persist after services are restored, contact the platform through SUNX’s official customer support channels for verification and resolution.

V. Important Reminders

This upgrade is part of the platform’s routine database and system version maintenance and aims to improve system stability and trading service capabilities.

The brief service impact during the upgrade may prevent trading requests from being submitted promptly. Please fully assess the relevant risks based on market volatility and your positions, and trade cautiously.

The SUNX technical team will continuously monitor the upgrade process and system operations, making every effort to minimize the duration of the service impact. We appreciate your understanding regarding any inconvenience caused.

SUNX will continue improving its technical infrastructure to provide users with more stable, efficient, and reliable trading services.

Thank you for your support and trust in SUNX.
