However I think this is out of date. The last 3 fields does not seem to map.
'fytoken', 'name', 'instrument_type', 'lot', 'tick', 'isin', 'trad_ses', 'last_upd', 'expiry_dt', 'symbol', 'exchange', 'segment', 'script_code', 'short_sym', 'strike', 'opt', 'fytoken'
Can you please check and correct this.
