Tabbed Interface 
"""Websockets"""
from thefirstock import thefirstock

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

def depth_feed_data(data):
	print(data)

thefirstock.websocket_connection(
                            "{{userId}}", 
                            listOfTradingSymbol,
                            socket_connection=1,
                            activate_depth_feed=True,
							callback_depth_feed=depth_feed_data
					)
  • In the above code you can send the trading symbol in the list to subscribe for the feed,
  • You can choose the socket_connection 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_depth_feed then this will start
    posting the feed to that method.
