Dear users:

Due to recent market fluctuations, in order to improve the efficiency of API users' order placement and query, HTX plans to upgrade and optimize the API at 15:00 (GMT+8) on April 24, 2021, Singapore time. The details are as follows:

The validity period of clientOrderId has been changed from 24 hours after the original order creation to 8 hours. Specifically, the clientOrderId cannot be used 8h after the order was created. It is recommended that users query/cancel their orders through the orderid.

We’re really sorry for any inconvenience that might be caused by this change.

HTX
