passing data from within a class into the deflection

You are not defining nor using a Python class properly.

I think you need to do it like this (untested). I’ve added an __init__() method to initialize the class when an instance of it is created. In particular note how I added self. prefix to the self.process_message argument being passed to bm.start_trade_socket() since it’s a method of the class.

You may need to make bm an instance attribute, too. (i.e. everywhere it’s referenced.)

import websockets
from binance.client import Client
from binance.websockets import BinanceSocketManager

class BinanceFutures:
    def __init__(self):
        print("binance futures class")
        # websocket start
        futures_api_key = "oooo"
        futures_secret_key = "ppppp"
        client = Client(futures_api_key, futures_secret_key)
        bm = BinanceSocketManager(client)
        conn_key = bm.start_trade_socket('BNBBTC', self.process_message)

    def process_message(self, msg):
        print("message type: {}".format(msg['e']))
        # do something

if __name__ == "__main__":
    print("binance main")
