Dear valued users,
To provide you with better trading experience, Huobi USDT-margined swaps will upgrade the system from 10:30 am to 12:30 pm on Apr. 27, 2021 (UTC), while coin-margined futures, coin-margined swaps and Options will not be affected. The upgrade is expected to last for 120 minutes. During the upgrade period, users’ pending orders will be retained, but functions such as transferring margin, opening positions, closing positions, and cancelling orders will be temporarily suspended on API, Web, and APP. Within 5 minutes after the upgrade, only order cancellation and transfer-in functions will be available on API, Web and APP, while order placement and transfer-out functions will not be supported.
Please control risk by corresponding operations in advance, e.g. cancelling orders, adding margin, or closing positions before the upgrade. We apologize for any inconvenience it may cause. Thanks for your support and understanding.
If there is a large market fluctuation before the upgrade, Huobi Futures will delay it and make further notice. Please refer to the latest announcement on our official website.

Note: The estimated time for system upgrade may not be accurate, please check the latest update on our official Huobi Chat, WeChat, QQ or telegram groups.

Thanks for your support and understanding.
