Description of your issue

Nothing happened when I tried to fetch all Binance streams. It worked with 100+ symbols, but not with 500. Is there any solution? What is the maximum number of channels?

channels = {'depth20', 'miniTicker'}

Binance made some restrictions 😕 https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/issues/45#issuecomment-619419025

to stream everything from binance without much effort you can use this script: https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/blob/master/example_stream_everything.py

It works with unicorn-binance-websocket-api 1.12.0!

[oliver-zehentleitner]

This idea with “virtual stream interface” is solved with update 1.10.0: https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/issues/38
