Continuing the discussion from Option chain is not fetching:
Hello @Tradehull_Imran sir,
I am getting an error in the code below. When I run it with a single or individual stock code, it works correctly. However, when I run the code with a watchlist, it gives me an error for every second name.
Please help me to fix this error.
Code:
import pdb
from Dhan_Tradehull import Tradehull
import pandas as pd
client_code = “-”
token_id = “-”
tsl = Tradehull(client_code,token_id)
watchlist = [‘UNIONBANK’, ‘VEDL’, ‘WIPRO’]
for names in watchlist:
atm, optchain = tsl.get_option_chain(Underlying=names, exchange=“NFO”, expiry=0, num_strikes=10)
print(f"\n{names}\n next\n")
