Duplicate Trading Symbols in https://images.dhan.co/api-data/api-scrip-master.csv

Learn with Dhan 📖

There are many duplicate SEM_TRADING_SYMBOL values in https://images.dhan.co/api-data/api-scrip-master.csv; are these valid ones? For example:
“199036 EQUITY ICICINFINAV ICICI Pru Nifty 100 ETF”
“199122 EQUITY ICICINFINAV INAV ICICI PRU NIFTY INFRA ETF”

When there are duplicate entries, how do we decide the correct one? Do you have plans to correct these?

Hello @abhilashbr

Welcome to Dhan Community! There are no duplicate entries as such in the Security ID Master. Over here, in the example shared by you, it is clear that both the scrips are completely different. One of the is ‘ICICI Pru Nifty 100 ETF’ whereas the other one is ‘INAV ICICI PRU NIFTY INFRA ETF’ which are two different scrips.

Hope this answers your question!

If both are different scrips, why are the trading symbols same for both?

Hello @abhilashbr

We checked for this instance and it turns out both the scrips are suspended for trading on Exchange. This might be one of the reason for having duplicate trading symbols. There are hardly few such cases where trading symbols are duplicate.

Moreover, all Dhan APIs work on ‘Security ID’ to avoid such instances of duplicacy or consistency in Trading Symbols across platforms. Also, there are additional columns available for you to verify the other scrip details.

ATUL and CHOLAFIN are still duplicates. I am looking at all equity types, on NSE exchange.

Hello @tradata

Welcome to Dhan Community!

This should not happen, will check the filtering here. Thank you for highlighting this.

@Hardik I raised this issue long back but no update yet: [Issue] Same equity symbol for multiple instrument

Hello @sv28

We are introducing two other columns which will help you filter based on Instrument Type. This will solve the issue that you earlier highlighted.

Meanwhile @tradata’s highlighted issue is different, which we are looking into.
