Error while getting tradingsymbol using kite.instruments

technoni

Below code was working earlier like few months back. But on new AWS machine its giving error as below. Kindly assist.

if instrumentsList is None:
instrumentsList = kite.instruments('NFO')

lst_b = [num for num in instrumentsList if num['expiry'] == expiry and num['strike'] == strike and num['instrument_type'] == ins_type
and num['name'] == name]
return lst_b[0]['tradingsymbol']

symbol_ce = get_symbols(nte, 'BANKNIFTY', atm_strike, 'CE')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "C:\tRADING\Python\ExpiryStraddle.py", line 122, in get_symbols
return lst_b[0]['tradingsymbol']
~~~~~^^^
IndexError: list index out of range

lst_b = [num for num in instrumentsList if num['expiry'] == expiry and num['strike'] == strike and num['instrument_type'] == ins_type
and num['name'] == name]
return lst_b[0]['tradingsymbol']

get_symbols(nte, 'BANKNIFTY', atm_strike, 'CE')

Your above get_symbols method is returning no matching instrument. You need to debug on that.
