Dear API user,
Unfilled order amount, is essential information for an order. However, inside the existing websocket updates, Huobi Global doesn’t really support this information for those passive orders which being partially filled.
Since the effectiveness of this notification, Huobi Global will be supporting unfilled order amount for all types of orders.
Effective Date：August 2, 2019 (GMT+8)
All the changes will be updated on https://huobiapi.github.io/docs/spot/v1/en/
