Dear KuCoin API Users,

In order to improve the performance of KuCoin API, KuCoin Spot/Margin/ETF will carry out a live upgrade at 7:00 AM (UTC) on June 19, 2024. The upgrade time will be 30 minutes. The websocket push of user balance/private order/l2 increment might cause loss or delay during the upgrade period.

If there is a large market fluctuation before the upgrade, we will postpone the upgrade according to the market change by announcement notice.
