Hello,
While Full Mode is on, If we want to listen ticks of no volume instrument we are getting error from Kite that “Invalid argument” and getting out of code. Error details has been given below,
Kindly suggest, how to handle this exception from Kite side ?
Scenario of Problem:
While listening option chain , there are many strikes where no trades executed, then following error is throwing from Kite and we are out of code.
def on_connect(ws, response):
ws.subscribe(token_list)
ws.set_mode(ws.MODE_FULL, token_list)
print(“on_connect”)
Assign the callbacks.
kws.on_ticks = on_ticks
kws.on_connect = on_connect
kws.on_close = on_close
Infinite loop on the main thread. Nothing after this will run.
You have to use the pre-defined callbacks to manage subscriptions.
kws.connect(threaded=True)
kws.connect()
