@Moderator_2 Thank you for your kind and prompt responses.

Kindly help how do we fetch open interest for historical data of options. I am using the below line of code but it is showing an error as

Historic Api failed: 'Series' object has no attribute 'open_interest' BANKNIFTY20DEC2346000CE

Code is as below:
historicParam = {
"exchange" : symbolInfo.exch_seg,
"symboltoken": symbolInfo.token,
"interval": "ONE_MINUTE",
"fromdate": "2023-12-15 09:15",
"todate": "2023-12-15 15:30",
}
res_json = obj.getCandleData(historicParam)
columns = ["timestamp", "open", "high", "low", "close", "volume"]
df = pd.DataFrame(res_json["data"], columns= columns )
df["open_interest"] = symbolInfo.open_interest

Without Open interest the code works fine. Thanks in advance
