@admin Will you please look where is the problem?
Thank you.
Following is the Code that I am using for live feed.

from smartapi import SmartConnect
from smartapi import SmartWebSocket

apikey = 'MlxYOLdb'
username = 'B96820'
pwd = 'password'
obj = SmartConnect(api_key=apikey)
data = obj.generateSession(username,pwd)
refreshToken= data['data']['refreshToken']
feedToken=obj.getfeedToken()
FEED_TOKEN = feedToken#"0980248722"
CLIENT_CODE = username
token = "nse_fo|108809&nse_fo|56855&nse_fo|5694&nse_fo|56906"
ss = SmartWebSocket(FEED_TOKEN, CLIENT_CODE)
task = "mw"

def on_message(ws, message):
print("Ticks: {}".format(message))

def on_open(ws):
ss.subscribe(task, token)
print("on open")
ss.subscribe(task, token)

def on_error(ws, error):
print(error)

def on_close(ws):
print("Close")

ss._on_open = on_open
ss._on_message = on_message
ss._on_error = on_error
ss._on_close = on_close

ss.connect()
