KuCoin Margin high-frequency API will undergo a non-stop system upgrade at 8:00:00 AM (UTC) on January 24, 2024. The upgrade time takes 30 minutes. In this upgrade, we will standardize the format of high-frequency magin trading error codes and add a series of new error codes. The new error codes will become effective immediately after the upgrade completes.

If you only trade spot, futures, or only use margin low-frequency accounts, this update will not impact you.
For specific error codes, please refer to the document: https://www.kucoin.com/docs/basic-info/errors-code/margin-errors-code
