Manually… if you want to look for all the options.

  1. Open the file. 2. Apply filter on the column ‘SEM_EXM_EXCH_ID’ to select ‘NSE’ only. 3. Apply filter on the column ‘SEM_INSTRUMENT_NAME’ to select only ‘OPTIDX’.
    Now you are left with all indexes options data on NSE.
    Target column ‘SEM_CUSTOM_SYMBOL’ for an easy search. Lets say you are looking for security id for bank nifty 24th July 52400 PUT. The format for custom symbol is 'BANKNIFTY . So you will serach for ‘BANKNIFTY 24 JUL 52400 PUT’.

Programatically… use the same logic as above to lookup.
search_column1 = ‘SEM_EXM_EXCH_ID’
search_value1 = ‘NSE’
search_column2 (str) = ‘SEM_CUSTOM_SYMBOL’
search_value2 = ‘BANKNIFTY 24 JUL 52400 PUT’

def lookup_entry(search_column1, search_value1, search_column2, search_value2, result_column):
    """
    Lookup function to find the value in 'result_column' based on 'search_column' and 'search_value'.
    
    Parameters:
        search_column1 (str): The name of the column1 to search in.
        search_value1: The value1 to search for in the search column.
        search_column2 (str): The name of the column1 to search in.
        search_value2: The value1 to search for in the search column.
        result_column (str): The name of the column from which to retrieve the result.
        
    Returns:
        result: The entry found in 'result_column' corresponding to the 'search_value'.
    """

Hello @Dhruv_Sharma1

In order to find out the Security ID, you can visit here : Instrument List - DhanHQ Ver 1.0 / API Document . In order to get the Security ID for Bank Nifty filter the SEM_SEGMENT as I, by doing so you will be able to get the same.

#for NIFTY
data = dhan.option_chain(13, under_exchange_segment=“NSE_IDX”, expiry=“2024-11-28”)
print(data)

it was working before but now start giving error:-
{‘813’: ‘Invalid SecurityId’}

your expiry list function also stop working

expiry = dhan.expiry_list(13, under_exchange_segment=“IDX_I”)
or
expiry = dhan.expiry_list(13, under_exchange_segment=“NSE_IDX”)

what are you doing, you are irritating too much
