Hi @stace.manley,

You are using the API correctly. If you don't provide any fields in your request, the service will return all available fields for the specific item you are requesting. For example:

df = ek.get_timeseries(['O-KRINV-P'],start_date='2015-01-01',
                                     end_date='2021-12-31') 
df 

Will return the month-end trade price as you observed, i.e. 'VALUE'.

You can also use the rdp library to retrieve historical summaries, i.e.

rdp.get_historical_price_summaries(
        universe = 'O-KRINV-P', 
        interval = rdp.Intervals.MONTHLY,
        start = '2015-01-01',
        end = '2021-12-31'
)

Unfortunately, this too only provides the trade price.

I would open a ticket within Refinitiv Support to determine if the historical data you are looking for using the item you provided is programmatically available.

I got Field name 'VALUE' to work but this is not supplied in the fields list for the ric

thanks
