Hello Moderator

I am getting an AB1004 error while querying for any symbol for historical data. My client code is R16888. Can you please check if the API is functional and active for my account?

There are a couple of suffixes for NSE symbols, such as "-BL", "-EQ", "-GE" etc. For e.g. "PAGEIND-EQ", and "PAGEIND-BL" both have similar properties in the master list like below

{
"token": "14415",
"symbol": "PAGEIND-BL",
"name": "PAGEIND",
"expiry": "",
"strike": "-1.000000",
"lotsize": "1",
"instrumenttype": "",
"exch_seg": "NSE",
"tick_size": "5.000000"
}

{
"token": "14413",
"symbol": "PAGEIND-EQ",
"name": "PAGEIND",
"expiry": "",
"strike": "-1.000000",
"lotsize": "1",
"instrumenttype": "",
"exch_seg": "NSE",
"tick_size": "5.000000"
}

Why do we have two or more entries in the master list for a single NSE symbol?
