import datetime

from datetime import date

import pandas as pd

import matplotlib.pyplot as plt

import numpy as np

from nsepy.derivatives import get_expiry_date





eexpiry = max(get_expiry_date(year=2019, month=12))

print (expiry)





nifty_fut = get_history(symbol="RELIANCE",

        start=expiry,

        end=expiry,

        futures=True,

        expiry_date=expiry)



niftydata = nifty_fut



nifty_opt = get_history(symbol="RELIANCE",

        start=expiry,

        end=expiry,

        option_type='CE',

        strike_price=1200,

        expiry_date=expiry)



optiondata = nifty_opt



y = expiry + datetime.timedelta(days=1)-----##Successfully implemented

Hi Mukul, 



You have stored expiry dates in eexpiry and calling expiry everywhere.



for x in range (4,13):

    expiry = max(get_expiry_date(year=2018, month=x))



Try changing the year in the above code. It might solve your issue.

Thanks for your support, Vibhu…







for x in range (4,13):

    expiry = max(get_expiry_date(year=2020, month=x)) 



issue resolved for 2020 expiry, can you pls share how I can add 2021 or recent months data.

You have to change the range to get the year 2021 data.



Try this:

for x in range (1,4):

    expiry = max(get_expiry_date(year=2021, month=x))
