Websockets running as background process using thread

listOfTradingSymbol = ["Nifty Bank", "Nifty 50"]


def subscribe_feed_data(data):

# Modify the websocket_connection function to accept the handler as an argument
thread = thefirstock.websocket_connection(
    handler,

  • In the above code you can send the trading symbol in the list to subscribe for the feed,
  • You can choose the callback_sub_feed either to 1 or 2 and can maintain two connection simultaneously.
  • Once the above steps are done, you can create a method and provide it as a callback to the callback_sub_feed then this will start
    posting the feed to that method.
