I'm running into the same issue @aeron7

replace index_history function with below function body in rahu.py

def index_history(symbol,start_date,end_date):
data = {"name": symbol,
"startDate": start_date,
"endDate": end_date,
}
data={"cinfo":json.dumps(data)}
payload = requests.post('https://www.niftyindices.com/Backpage.aspx/getHistoricaldatatabletoString', timeout=300, headers=niftyindices_headers, json=data,).json()
payload = json.loads(payload["d"])
payload=pd.DataFrame.from_records(payload)
return payload

def index_history(symbol,start_date,end_date): data = {"name": symbol, "startDate": start_date, "endDate": end_date, } data={"cinfo":json.dumps(data)} payload = requests.post('https://www.niftyindices.com/Backpage.aspx/getHistoricaldatatabletoString', timeout=300, headers=niftyindices_headers, json=data,).json() payload = json.loads(payload["d"]) payload=pd.DataFrame.from_records(payload) return payload

This is working. Thanks
