Hi @Surendra_Singh1 ,

Refer the below code:

 option_chain = tsl.get_option_chain(Underlying="NIFTY", exchange="INDEX", expiry=0, num_strikes=10)
  • expiry (int): Index of the expiry date in the list of available expiry dates
    0 for the nearest expiry
    1 for next expiry and so on.

Hi @Tradehull_Imran ,
Thanks for replying i got the option chain data but we are getting option greek (‘delta’) value wrong for weekly expiry strikes Nifty option chain
for monthly expiry we get correct value for stocks options as i use below code

delta_values = tsl.get_option_greek(strike=25200, expiry=0, asset=‘NIFTY’, interest_rate=10, flag=‘delta’, scrip_type=‘CE’)
