The upgrade is estimated to take 15 minutes, during which futures trading services, including order matching and placement, adding margin, etc. will be suspended. Please take necessary measures before the downtime, such as lowering the leverage, reducing positions, or adding margin to avoid potential risks like forced-liquidation caused by market volatility. If any volatile market movement is observed before the upgrade, we may postpone it to a later time when the market's stability is ensured.
