Price history for some of the delisted stock RICs in your list is not available because the RIC was superseded by another one. E.g. ALT.N^K99 delisted in 1999 was replaced by ATI.N, which has price history going back to 1989. BNET.O^B96 was superseded by BAY^H98.

When requesting timeseries of price history for delisted stocks, the time range in the request must overlap with the life time of the stock. E.g. ek.get_timeseries('ONE.N^G04') returns "No data available for the requested date range" because by default get_timeseries method requests the time range of the 100 days back from today whereas the stock was delisted back in 2004. By contrast ek.get_timeseries('ONE.N^G04', start_date='20030101', end_date='20031231') returns the timeseries, as one should expect.

Finally there are some RICs on your list like BOAT.O^D99 that don't have price history, and I'm not sure why. Perhaps because back in the 1990s and early 2000s Reuters was not diligent in keeping price history for delisted stocks, especially for small and mid caps.

Please find below the list of tickers in which no data is received (paste with a different format):

Hi @f.janeiro

From the API usage point of view, I only want to raise one concern that get_timeseries() cannot return more than 3000 records in a single API call.

Please refer to this limitation document, https://developers.refinitiv.com/en/api-catalog/eikon/eikon-data-api/documentation

In your API call, you try to retrieve daily data for 30 years (around 7-800 records per RIC).

So you should split them into a smaller RIC list or smaller time period.

For the content related issue:

I just tested these RIC (without parameters).

It seems that some of the RICs are invalid and some of them are valid and carry some information.

I suggest that you should clarify what RIC and what period that the data is available with Refinitiv Content Helpdesk at https://my.refinitiv.com/

The code is valid (expect that it exceed the data limitation for get_timeseries())

So you need to verify if the RIC and period are also valid or not?

When running the fetching I'm looping through the list one ticker at the time, so no problem with the data size limitation of 3000. I just wanted to display the full list of issues I was getting.

Hello Alex Putkov.

I understand that some old RICs of delisted stocks might not have price history in the database.

However, some still alive stocks seem to have a quite incomplete price history. Please check the following examples:

AMCR.N, ARNC.N, FTI.N, GRA.N, IR.N, JWN.N, MAR.OQ, RF.N, TAP.N.

Let's take the FTI.N example. This stocks seems to be part of the SP500 since 2009, but price history only comes in the API fetch since 2017.

Could these a similar issue to the data missing situation mentioned for GOLD.N in the below ticket that ended to be solved?

Thank you in advance.
