The specialist updates the ticket 09661076 as the following:

The problem you are encountering is related to the different shapes of the resulting dataframes. This is one of the limitations of the method, ek.get_timeseries, therefore normally I would advise going with the ek.get_data() method, BUT for this specific example, we have an issue with USD1MD=EQBK, which lacks the correct TR fields. The syntax for the second instrument will look like this:

df,err = ek.get_data(instruments = ['USD1MD='], fields = ['TR.BIDPRICE', 'TR.BIDPRICE.date'], parameters = {'SDate':'20210101', 'EDate':'20210225'})

df

But for your problem, I figured out a workaround. It requires some work on adjusting the time series, but the result looks ok.

Try this code:

first = ek.get_timeseries(['USD1MD=EQBK'], start_date='2021-01-01', end_date='2021-01-31', fields='CLOSE', raw_output=False)
second = ek.get_timeseries(['USD1MD=EU'], start_date='2021-01-01', end_date='2021-01-31', fields='CLOSE', raw_output=False)

first = first.reset_index()
first['Date'] = first['Date'].drop_duplicates()
first = first.dropna()
first = first.set_index('Date')

first = first.asfreq('D',method = 'bfill')
second = second.asfreq('D', method = 'bfill')

combined = pd.merge(first, second)
combined

Hi @anni.wang

I submitted ticket no. 09661076 on your behalf.

A support team will contact you about the issue.

These 2 codes work fine:

But when combining the instruments, the API could not handle the returning data.

(The request is valid, API receives response from the backend)

Hi, since I need to do a 1000 rics, the above code didn't work but you have pointed out the problem. I built a For loop to get the data one at a time for each Ric. However, I had some new issues. A lot of the rics not returning data. However if I search the rics in reuters, they do come up with data. For example USD1MD=UBTA, USD1MD=HVBG return error messages. Some rics do work well in the code below. For example USD1MD=LOYL, USD1MD=VBAH work well

See my code below and error message below.

The ContributorRics ['1M'] includes the rics mentioned above and the ones shown in the error message below.

code:

---------------------------------------------------------------------------

ric_dict=dict()

for ric in ContributorRics['1M']:

try:

data_sr = ek.get_timeseries(ric,start_date='2021-02-01',end_date='2021-03-2',fields='CLOSE').squeeze()

data_sr = data_sr.drop_duplicates()

ric_dict[ric]=data_df

except:

print(ric)

print("Unexpected error:", sys.exc_info()[0])

continue

------------------------------------------------------------------------------------------
