$all@allTickers not working on binance.com but working on binance.org

[salian]

When I use BinanceWebSocketApiManager with binance.com exchange and $all@allTickers I get HTTP error 400 Bad Request.

But the same code works fine with binance.org and returns data on websocket.

def run_main_loop(api_key, api_secret):
    binance_websocket_api_manager = BinanceWebSocketApiManager(exchange="binance.com")
    binance_websocket_api_manager.create_stream('allTickers', ['$all'])

    while True:
        oldest_stream_data_from_stream_buffer = binance_websocket_api_manager.pop_stream_data_from_stream_buffer()
        if oldest_stream_data_from_stream_buffer:
            print(oldest_stream_data_from_stream_buffer)

The debug log:

Indeed it was my misunderstanding that all Binance endpoints are reasonably alike. $all@allTickers is not available on binance.com exchange. It's only available for dex (binance.org) exchange.

As per https://binance-docs.github.io/apidocs/spot/en/#all-market-tickers-stream the alternative equivalent for websocket stream with every-second updates on 24hr rolling window ticker statistics for all symbols is !ticker@arr

For the sake of anyone who finds this thread, a working example for all tickers would be

from unicorn_binance_websocket_api.unicorn_binance_websocket_api_manager import BinanceWebSocketApiManager

def run_main_loop():
    binance_websocket_api_manager = BinanceWebSocketApiManager(exchange="binance.com")
    binance_websocket_api_manager.create_stream('arr', '!ticker')

    while True:
        oldest_stream_data_from_stream_buffer = binance_websocket_api_manager.pop_stream_data_from_stream_buffer()
        if oldest_stream_data_from_stream_buffer:
            print(oldest_stream_data_from_stream_buffer)

if __name__ == "__main__":
    run_main_loop()
