Hi ! I've been talking with the LSEG helpdesk and i've been provided an answer :

df = rd.get_data(
universe =
['1SPXFM4',
'ESH25'],
fields = ['MNEMONIC']
)

This can fetch the root RICs for the given RICs. I've yet to test it but it looks promising

Hi @adam.leroux,

I am not sure, if there is a direct way to get the RIC root, I asked the Helpesk to learn more about it and will update you here. However I may have a solution for the second part of your problem, which is reconstructing RIC codes based on some parameters. Please check my article below which includes a Github repo link on the right:

Reconstructing RICs for expired futures contracts | Devportal (lseg.com)

I have created a python function which takes RIC root, expiration month and the year as an input and returns the futures RIC. For example for SPX that would be:

fr.get_futures('ES', 3, 2021)

Hope this helps for building the RIC. I will come back to you re finding the RIC root once get an update.

Best regards,

Haykaz

It could be search API in the Refinitiv Data Library for Python.

df = rd.discovery.search(
    view = rd.discovery.Views.SEARCH_ALL,
    query = "S&P500 EMINI",
    select = "BusinessEntity,DocumentTitle,RIC,RicRoot",
    top = 100)
df

The examples are on GitHub.

Hi @adam.leroux ,

I have learned from Helpdesk that there is no straightforward way to get the RIC Roots (please note that there are many not just one) and my colleague's suggestion above seems to be the best approach we have. What you can further do is apply some additional filter criteria to get only the RIC roots you are interested in, for example:

df = rd.discovery.search(
view = rd.discovery.Views.EQUITY_QUOTES,
top = 1000,
filter = "(AssetState eq 'AC' and SearchAllCategory eq 'Futures' and SearchAllCategoryv2 eq 'Futures' and ((UnderlyingQuoteRIC eq '.INX')))",
select = "RIC,SearchAllCategoryv2,SearchAllCategory,DTSubjectName,ExpiryDate,UnderlyingQuoteRIC, RicRoot"
)
df

Best regards,

That is great that you are provided with a workable solution. I was initially thinking you wanted to input instrument RIC, eg .INX or .SPX and get the RIC Roots (such as ES) back where the code with MNEMONIC will not return anything. Nevertheless, this is a solution if you provide futures RICs as an input Universe.
