Retrieving RICs from eikon API 'as of'

new_account_l

Hello,

I am trying to retrieve some RICs price tickers from the eikon API like this:

import refinitiv.data as rd
rd.open_session()
eikon_data = rd.get_data(
ric_list,
fields=['BEST_BID1',…]
)
rd.close_session()

This returns live data. How can I retrieve this data as of yesterday? Or as of two days ago?

I would like to be able to retrieve from the API what some RICs were yesterday.

Please let me know, I would be very grateful

Thank you!

Thank you for reaching out to us.

You can use the get_history method to retrieve real-time data. I recommend to use the LSEG Data Library for Python instead. The examples are on GitHub. You can ignore the fields parameter to retrieve all available fields for real-time data.

In addition to real-time fields, there are the TR.xxx fields, such as TR.BIDPrice which can provide timeseries data. You can use the Data Item Browser tool to search for the TR.xxx fields and parameters.

For example:

ld.get_history(
    universe = ['LSEG.L'],
    start = '2026-01-08',
    end = '2026-01-12',
    interval = '1d')
                

ld.get_history(
    universe = ['LSEG.L'],
    fields = ['TR.BIDPrice'],
    start = '2026-01-08',
    end = '2026-01-12',
    interval = '1d')

You can also contact 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 or =RDP.HistoricalPricing, that can be used to retrieve the required data. Then, we can help you converting that formula to Python code.
