Thank you for reaching out t us.

This forum is dedicated to software developers using LSEG APIs. The moderators on this forum do not have deep expertise in every bit of content available through LSEG products, which is required to answer content questions such as this one.

The best resource for content questions is the Helpdesk support team, which can be reached by submitting queries through LSEG Support. The support team will either have the required content expertise ready available or can reach out to relevant content experts to get the answer for you.

You need to ask for the Excel formula, such as =RDP.Data, that can be used to retrieve the required data. Then, we can help you converting that formula to Python code. You can also refer to these articles:

• How to Convert the =@RDP.Data Excel Function into Code Using the LSEG Data Library for Python
• Converting =RDP.HistoricalPricing() Excel Function to ld.get_history() in Python

Otherwise, you can use the Data Item Browser tool to search for fields and parameters.

I checked and found that the TR.CompanyMarketCap field supports these parameters.

For example:

df = ld.get_data(
    universe=["LSEG.L"],
    fields= [ "TR.CompanyMarketCap",
              "TR.CompanyMarketCap.Date",
              "TR.CompanyMarketCap.Currency",],
    parameters={
        "SDate": "0",              
        "EDate": "-19",
        "Frq": "FY",              
        "Curn": "USD"
    }
)

I am using LSEG Data Library for Python. The examples are available on GitHub.
