【System Upgrade】SUNX Database and Version Upgrade Schedule (2026-09-03)

Dear Users,

To further improve system stability and service quality, SUNX plans to perform a database and version upgrade at 07:00 on Thursday, September 3, 2026 (UTC+8). The schedule and expected impact are detailed below.

I. Upgrade Schedule

• Start time: September 3, 2026, at 07:00 (UTC+8)
• Estimated duration: Approximately 10 seconds

Brief service disruptions may occur during the upgrade. Please arrange related trading activities in advance.

II. Expected Impact

1. Contract, spot, and options trading: Order placement may fail during the upgrade. Trading requests may also be delayed, or order placement may become temporarily unavailable.
2. Deposits and withdrawals: These services will not be affected and will remain available as normal.
3. Frozen funds: Funds frozen as a result of failed order placement will be automatically unfrozen.

III. Trading Instructions

1. Plan trading activities in advance: Assess market volatility and trading risks during the upgrade based on your positions, orders, and trading plans.
2. Confirm order status: If you submit an order during the upgrade, promptly check your order and execution records to confirm the actual result.
3. Avoid duplicate submissions: If the page responds slowly or displays an error message, first verify whether the order has been submitted or executed to avoid unintended trades caused by repeated actions.
4. Check fund status: If order placement fails and funds are frozen, monitor the automatic unfreezing result. If you have questions, contact SUNX through its official customer support channels.

IV. Risk Warning

Order submission failures, delayed trading requests, or temporary unavailability of order placement may occur during the upgrade. Market fluctuations, network delays, and failed order placement may result in missed trading opportunities or other potential losses.

Please manage your positions and funds appropriately, fully assess the relevant risks, and trade cautiously. If you need to place orders during the upgrade, be sure to verify order status and actual execution results.

SUNX will make every effort to minimize the upgrade duration and continuously monitor system operations. We appreciate your understanding regarding any inconvenience caused.

Thank you for your understanding and support!
