Max message size for websocket subscription

Websocket
1

The documentation says 1024 streams can be subscribed on a single websocket connection. I am trying to start this subscription for all 1024 streams at a time using a single request with method=SUBSCRIBE as described here

But I get the parsing error from Binance while doing this through my own C++ implementation. I tried the same with python-binance in python and I see that I am able to successfully subscribe at a time to 825 streams but not 826 streams.

I would like to know if there is a limit on message size that I can send on websocket.

Hi,

There is a limit of 5 messages per second. The limit of 1024 streams means that you can slowly build up to 1024 streams by submitting 5 streams per second. As for maximum message size, it can vary but its generally not recommended to send messages over 16kb in size.

Hopefully that helps clarify.
