Few Singapore Securities [ex GGR SP, GGR2 SP] has the same ISIN code and listed on the same exchange. The only difference in these securities is tradable lot size.

Does any one know how is the FIX standard to get the unique stock when we use the ISIN to lookup the security Master.

MY client is sending the FIX order with 48/22/100. With these we still get 2 valid stocks and MY FIXEngine rejects as it could not get the unique stock.

Do you have any suggestions?

Use ISIN + SGX code i.e. code for Singtel (Z74), SingTel 10 (Z77) and SingTel 100 (Z78)

Client is sending us the wrong SGX code in Tag 55 and hence we ignore it.

It looks to me [GGR2 SP] is delisted since 5/11/09. So your engine should find [GGR SP] as the sole hit.
We also use 48/22/100 or 207 and whenever available tag15 (currency) to load security. As far as I know, this combo creates unique hit.

Dear Xinyu Xiang,

Thank you very much for your answers!

You are correct for stock [GGR2 SP], the stock is delisted. It may be my back example.

How about for the stock:[ENVH SP, ENVH1 SP], i have checked in the bloomberg both are active. Hence both will have same 48/22/100 if ISIN is used.

How do we over come if we do not user Tag55?

Hi Varaprasad,

I tried this out. Our software picks out “ENVH SP” as the best match. The other one does not seem to have any history trade data. Wish I could understand why it exists. Good luck.
