Cannot get NEXT_QUARTER price via websocket stream

As I found in document ( that I can subscribe next quarter by using wss:// But it doesn’t work for me.

Sending SUBSCRIBE method manually returns {\"result\":null,\"id\":1} while the other streams like btcusdt@aggTrade works for me.

Did I do something wrong? How count I get fix this? Thanks~

Hi. You have to change your base from stream to dstream as your subscription target belongs to futures market. That is, wss://


Thank you~
