Hello,

FID 997 (GEN_VAL2) is an illogical FID. Please note that not all illogical FIDs have a corresponding data item. This however, still returns the same value using the TR.OfficialAskPrice since it's the FID being used for official ask as can be seen on fixspec (below link).

Thanks for your kind reply paulcerillo

Could you tell me how to find the information that I want from the url that you linked with?

Hi the URL above is where we input the corresponding value of the FID#5357 for the instrument of our query. In this case, 1236 is the value FID#5357 CONTEXT ID for RIC <CMZN0>.

We then search for the FID 997 in FixSpec.

Hi, the fixspec (link above) allows you to view the FID details specific to the RIC's exchange or source.


For example, if you open in Q app <CMZN0 Q> and display all fields. You will see that the corresponding Context_ID (FID#5357) for CMZN0 is "1236". You can input this number on the search bar on the fixspec and search "GEN_VAL2" or "FID997".

You look for the Context_ID (FID#5357) of the RIC you are interested in and input it on the FixSpec data model dictionary.

Oh, and one more thing
You told me not to use inappropriate fields as parameters
There are quite a lot of gen_valX that I have received now
How can I find the field value that exactly maps to gen_val?

I did not advise not to use illogical fids. It's just to let you know that the fid you were using is illogical field. These type of fids are not "common" across other RICs. Some RICs may have a different value for FID#997.
