Important Update:
Since the launch of the high-frequency spot account last year, the stability of the spot API has significantly improved, and latency has been greatly reduced. However, currently, two systems coexist, and users using the low-frequency system still experience high latency and other issues. Therefore, from July to September, we will be merging and migrating the existing low-frequency and high-frequency systems. The overall process is as follows:

👉👉Important Upgrade👈👈

The Spot account upgrade originally planned from 2024.07.08 1:00 - 2024.07.10 10:00 (UTC) has been postponed to 2024.07.10 1:00 - 2024.07.12 10:00 (UTC).

During the upgrade process: Your Spot orders may be canceled, and you will not be able to place orders, cancel orders, or query account for a few seconds.

Once the upgrade is complete, your Spot trade latency will be reduced and system stability will be significantly improved.

We have recently upgraded apikey from the previous v2 version of apikey to v3.

We have automatically migrated some of the apikeys to the v3 version. Please check your apikey version. If it is still a v2 apikey, please upgrade to the v3 version as soon as possible. We will invalidate the v2 version of apikey in batches from 2024.08.01 - 2024.08.10. By then, the v2 version of apikey will not be available.

Upgrade method:

This upgrade method is a compatible upgrade, which does not require the client to modify any code. It only needs to re-create a new version of v3 apikey and replace the old version of v2 apikey.
