Description of your issue

As mentioned in title, BinanceWebSocketApiManager does not accept parameter exchange="binance.com-coin-futures".
The reason is unicorn_binance_websocket_api_manager.py does not define binance.com-coin-futures in if-clause.

Since the documentation describes 'binance.com-coin-futures' is applicable for exchange parameter, I thought that this endpoint has mistakenly deleted or deprecated somehow, while change log does not mention anything about this.
Is there any way to connect wss://dstream.binance.com/ endpoint? 

Waiting for your catch ups.
Sincerely,

Hi! coin-futures is not released yet and only available in the dev stage: https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/blob/master/CHANGELOG.md

If you want to try the dev stage just install this way: https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api#from-the-latest-source-dev-stage-with-pip-from-github

Appreciate for your immediate response! Sorry I didn't fully read through dev version which made me confused! My bad.

By the way, I propose that the documentation which is suggested during handling Exceptions should refer somewhat to the exchange parameter "coin-futures" is under dev stage, which helps users' clearer understanding!

Like: exchange (str) – Select binance.com, binance.com-testnet, binance.com-margin, binance.com-margin-testnet, binance.com-isolated_margin, binance.com-isolated_margin-testnet, binance.com-futures, binance.com-futures-testnet, binance.com-coin-futures*, binance.je, binance.us, trbinance.com, jex.com, binance.org or binance.org-testnet (default: binance.com) *only available on dev-stage version

I think it was a mistake that i updated the docs... sorry for confusion!

On pypi you see the description related to the version: https://pypi.org/project/unicorn-binance-websocket-api/1.30.0/

We added coin-futures and it should be released with 1.31.0 and prepared README and other things, but docs should have been excepted.

This will be cleaned with the next release ;)
