1. Impact and timelines

Between 07:38:07 AM and 07:43:01 AM UTC on September 13, 2023, certain trading products were affected by anomalous prices.

The timeline for this incident is detailed below:
07:38:07 AM UTC: Anomalies in the trading systems were detected. Our developers immediately became aware of the problem through monitoring and alerts as user reports also began to come in.
During this period, we pinpointed the reason for the disruption following an emergency investigation. We then executed a repair solution, specifically targeted at optimizing system configurations.
07:43:01 AM UTC: Trading systems resumed normal functions.

2. What caused this disruption?

The limit price services used by the trading system were disrupted due to updates in system configurations. Consequently, orders couldn’t be placed for some trading products, causing price discrepancies that triggered certain users’ liquidation or stop loss mechanisms.

3. What steps are we taking to avoid this in the future?

1). Optimize update procedures for system configurations and deployment procedures;
2). Strengthen the trading system’s stability by reducing interdependencies between internal systems, thus lowering potential risks;
3). Refine the ‌internal monitoring system by implementing more precise monitoring of our system’s limit price mechanisms.
