Scheduled - Dear Valued Users,
To offer you a better trading experience, Huobi coin-margined swaps will undergo a system upgrade with service suspended from 09:30 (UTC) to 11:00 (UTC) on Nov 19, 2021. Coin-margined futures and USDT-margined swaps will not be affected.

During the upgrade period, users' pending orders will be retained, but other functions such as margin transfers, opening and closing positions, and order cancellations will be temporarily suspended for API, Web, and APP. Order cancellation and transfer-in functions will be available via API, Web and APP within 5 minutes after the upgrade is completed, while order placement and transfer-out functions will not be available.
Please be sure to manage your risk by making corresponding adjustments in advance, e.g. cancelling orders, adding margin, or closing positions before the upgrade. We apologize for any inconvenience this may cause. Thank you for your support and understanding.

Please note Huobi Futures will delay the upgrade should the market fluctuate substantially and will give further notice if this happens. Please refer to the latest announcement on our official website.

Note: The time required for the system upgrade is just an estimate. Please check the latest update on our official Huobi Chat, WeChat, QQ or Telegram groups.

Thank you for your support and understanding.

尊敬的用戶：
您好！為了給您提供更好的交易體驗，Huobi Futures將於新加坡時間2021年11月19日17:30-19:00（GMT+8）對幣本位永續合約進行系統升級。幣本位交割合約和USDT本位永續合約不受影響。

升級期間，用戶原有掛單會繼續保留，API、Web和APP將無法進行劃轉擔保資產、開倉、平倉、撤單等操作；升級結束後的5分鐘之內，用戶在API、Web和APP只能撤單和轉入，無法下單和轉出操作。

請您提前做好相應安排，並通過升級前撤單、追加擔保資產、或提前平倉等方式做好風險控制。由此帶來的不便平臺深表歉意，感謝您的支持與理解！

若升級前市場行情出現較大波動，平臺會根據市場情況推延升級時間並發佈推延升級公告，一切請以官網公告為准。

注意：系統升級的預估時間可能並不準確，您可以通過官方火信群、微信群、QQ群、Telegram等方式關注最新進展。

感謝您對Huobi Futures的支持！

Thank you for your support!

尊敬的用户：
为了给用户提供更好的交易体验，Huobi Futures将于新加坡时间2021年11月18日16:00-20:00 (GMT+8)进行API性能优化。API性能优化期间， USDT本位永续合约的WebSocket订单和用户数据接口与WebSocket市场行情接口，以及币本位交割合约与币本位永续合约的WebSocket市场行情接口可能偶尔会出现断连的情况，建议您提前设置好WS断连后的自动重连机制。

感谢您对Huobi Futures的支持！
