Eikon Data API consistency across get_data and get_timeseries

reid

Hi -

I'm struggling to understand why I am more data from one function vs another when I believe they should have the same information. I've isolated one such example below as a test case but this is not the only one:

import eikon as ek

ek.set_app_key(XXXXXXXXXXXXXXX)

ticker = 'AMZN.O'

start = "2007-10-05"

end = "2007-10-09"

df_getdata, err = ek.get_data(ticker, ['TR.PriceHigh.date','TR.PriceHigh'], {'SDate': start, 'EDate': end, 'FRQ': 'D'})

df_getts = ek.get_timeseries(ticker,
fields = 'HIGH',
start_date = start,
end_date = end)

When I print each I get:

df_getdata has values for Oct 5 and Oct 9, see below --

Instrument Date Price High

0 AMZN.O 2007-10-05T00:00:00Z 93.71

1 AMZN.O 2007-10-09T00:00:00Z 96.73

Whereas df_getts has values for Oct 5, Oct 8, and Oct 10

AMZN.O HIGH

Date

2007-10-05 93.71

2007-10-08 95.85

2007-10-09 96.73

So it would appear that Oct 8 is missing from the first call? Any idea what is going on?

Thanks much. I can provide other examples from other tickers / dates if needed.

df, e = ek.get_data('AMZN.O', ['TR.PriceHigh.date','TR.PriceHigh.value'],{'SDate': '2007-10-08', 'EDate': '2007-10-08', 'FRQ': 'D'})

I will raise this and let you know, thanks for reporting.

Can you please try with:

err = ek.get_data(ticker, ['TR.HighPrice.date','TR.HighPrice'], {'SDate': start, 'EDate': end, 'FRQ': 'D'})

Hi @marcin.bunkowski - I do indeed get all 3 dates when I use HighPrice vs PriceHigh, though a separate thread answer made it seem like the inverted code should be used for unadjusted data (https://community.developers.refinitiv.com/questions/30439/most-robustget-timeseries-or-get-data-for-historic.html)? In any event the both codes should return something for that date, no?

Thank you, look forward to figuring it out.

In theory those codes should get the same.

It looks that 2007-10-08 was a holiday in US (Columbus Day) and might be causing this anomaly. I'd wait for a reply from Refinitiv helpdesk as suggested by @Zhenya Kovalyov
