Failed returns on get_data

dgarrard

I have a routine that has been running fine for several months but now fails if I pass yesterdays date as a parameter, but if I pass the prior sessions date it works fine.

It seems that the data is not prepared for yesterday's session yet. Usually it runs successfully in the mid evening for New York and Toronto. Sometimes we need to wait, but it is always ready in the morning.

C:\PNC\Stats\Python>python.exe GetHighsLows.py High XNYS 20220418 -> FAILS

C:\PNC\Stats\Python>python.exe GetHighsLows.py High XNYS 20220414 ->SUCCEEDS

In ther traceback below, it suggests the header is not being found in yesterday's data.

Any ideas?

C:\PNC\Stats\Python>python.exe GetHighsLows.py High XNYS 20220418

Hi @dgarrard,

I believe that this is a content-related question. The API is behaving as expected - I tested it myself.

The best resource for content questions is the Refinitiv Helpdesk, which can be reached by either calling the Helpdesk number in your country or submitting a new ticket to the support team via MyRefinitiv.

Here is the script:

import sys
import refinitiv.dataplatform.eikon as ek
import pandas
ek.set_app_key()

DataSwitch_T = sys.argv[1]  # High, Low
Exch_T = sys.argv[2]   # XNYS, XTSE
Date_T = sys.argv[3]   # 20211203

# EIKON QUERY
instrument = "SCREEN(U(IN(Equity(active,public,primary,countryprimaryquote))),IN(TR.ExchangeMarketIdCode,'" + Exch_T + "'),BETWEEN(TR.Price52Week"+DataSwitch_T+"Date," + Date_T + "," + Date_T + "))"
df, err = ek.get_data(instrument,['TR.CommonName','TR.PRICECLOSE'])

file1 = open('C:\PNC\Logs\MIA_'+DataSwitch_T+'_'+Exch_T+'_'+ Date_T +'.txt', 'w')

df.to_csv(file1, index=False)
file1.close()

new_df = pandas.read_csv('C:\PNC\Logs\MIA_'+DataSwitch_T+'_'+Exch_T+'_'+ Date_T +'.txt')

print('~Beginning of Data\n')
print(new_df)
print('\n~End of Data')

This was an Eikon service (not specifically API) outage which lasted for about 4 days. It has since come back on line.
