Dear User,

In order to ensure a better API user experience, please use the spot and futures Websocket in a standardized manner, and be sure to use the push endpoint for the spot and futures separately:
POST /api/v1/bullet-public
POST /api/v1/bullet-private

Reminder: The mixed use of push endpoint for spot and futures will increase the delay by 5-10ms, please kindly pay attention to check.

Thank you for your understanding and support!
