Dear HTX Users,

To provide our users with a better trading experience, HTX will perform a system upgrade on HTX Coin-Margined Futures at 01:00 (UTC) on May 31, 2023. Further notice will be made if maintenance is delayed or canceled due to market fluctuation.

Some HTX services will be suspended during the upgrade, including:

• Coin-M delivery and Coin-M perpetual futures
• Coin-M futures API

Services for USDT-M perpetual and delivery futures will function normally during the upgrade.

Please close any open orders or cancel any pending orders in advance to avoid trading losses.

Due to the long suspension time, the closing of orders and positions cannot be performed during the service maintenance. HTX will provide a 20-minute protection period before regular trading resumes, allowing users to cancel orders and add margin. During this period, order matching system will remain closed, and no orders can be placed or executed. Once the protection period is over, our system will return to regular trading.

The upgrade is expected to last about 4-6 hours. We will announce once the maintenance is completed. You can get a status update on the maintenance by contacting our Customer Support.

We apologize for any inconvenience it may cause. Thank you for your support and understanding.

HTX remains committed to providing you with better products and services.

HTX
