Announcement on Cancelling Rate Limit for “Cancel an Order” Interface

Dear Valued Users,

To provide users with smoother trading experience, HTX plans to cancel rate limits for the API interface, “Cancel an Order”, at 6:00 am (UTC) on Oct 14, 2021.


  • Interface Name: Cancel an Order
  • Interface Type: Private
  • Interface URL: POST /v1/order/orders/{order-id}/submitcancel
  • Adjust the rate limit (NEW) from “100 times/2s” to “No”.

 For the API details, please refer to >>


Should HTX launch rate limits on all interfaces in future, it will apply “cancel an order” interface then. Announcements will be made subject to the need.  HTX strives to provide  better API trading experience to our users.

Thank you for your support!
