I am sending the following wss://stream.binance.com:9443/stream?streams=btcusdt@bookTicker/bnbbtc@bookTicker as per example and am getting a 400 rejection with the error text “One or more stream names are not valid”. I am doing everything as per example in Binance API Documentation and Binance API Documentation.
Anyone have any idea what the correct format for multiple streams is given that !bookticker has now been rmoved?
I just tested this and I’m not getting any errors like you described. It successfully subscribes to both bookTicker streams and returns data. Perhaps posting your code would help identify the issue?
