Does anyone know what is the latest Binance API function version of start_multiplex_socket,
start_user_socket, start_symbol_ticker_socket or similar from
BinanceSocketManager or another module to start socket connexion.
Would be very much appreciated !
Hello,
it seems you’re using python-binance, which is not the official library and therefore we don’t support. Although if you’re keen to explore to the official one, you can check at Binance Public API Connector Python — binance-connector documentation or GitHub - binance/binance-connector-python: a simple connector to Binance Public API.
Oh, so I could try with this library then,
Thanks a lot.
However, binance_connector is not recognized on Anaconda. It says the package in unavailable
Hi, it’s binance-connector actually. Try that instead.
pip install binance-connector is the recommended PyPi installation command.
In addition to python-binance and the binance-connector, there is also the UNICORN Binance Suite. Although it costs money, it works very reliably and is continuously developed and optimized: GitHub - LUCIT-Systems-and-Development/unicorn-binance-websocket-api: A Python SDK by LUCIT to use the Binance Websocket API`s (com+testnet, com-margin+testnet, com-isolated_margin+testnet, com-futures+testnet, com-coin_futures, us, tr, dex/chain+testnet) in a simple, fast, flexible, robust and fully-featured way.
For transparency, I am the programmer of the UNICORN Binance Suite and would like to present my solutions! 
Here is a full script for a multiplex stream:
from unicorn_binance_websocket_api import BinanceWebSocketApiManager
import asyncio
async def main():
async def process_asyncio_queue(stream_id=None):
print(f"Start processing the data from stream '{ubwa.get_stream_label(stream_id)}':")
while ubwa.is_stop_request(stream_id) is False:
data = await ubwa.get_stream_data_from_asyncio_queue(stream_id)
print(data)
ubwa.asyncio_queue_task_done(stream_id)
ubwa.create_stream(channels=['trade', 'kline_1m'],
markets=['ethbtc', 'btcusdt'],
stream_label="MULTIPLEX",
process_asyncio_queue=process_asyncio_queue)
while not ubwa.is_manager_stopping():
await asyncio.sleep(1)
with BinanceWebSocketApiManager(exchange='binance.com') as ubwa:
try:
asyncio.run(main())
except KeyboardInterrupt:
print("\r\nGracefully stopping ...")
except Exception as e:
print(f"\r\nERROR: {e}\r\nGracefully stopping ...")
once I launch my strategy bot my terminal displays this : APIError(code=-1121): Invalid symbol :

As you can see in the penultimate line “APIError(code=-1121): Invalid symbol.”, the symbol is wrong! We can only tell you exactly what the problem is once we know your code.
