How to backfill missing data?

in Eikon Data APIs

Hello,

There are always some missing data point for any inquiry and I understand that. For example:

ek.get_data('015351109', ['TR.PE'], {'SDate':'20180830'})

got nothing even 015351109 is a company on S&P 500 list.

My question is, is there a parameter in the ek.get_data function that can return the nearest available data if the data on '20180830' is not available? For example,

ek.get_data('015351109', ['TR.PE'], {'SDate':'20180730'}) has a value and I want to get that value return if my inquiry for data on '20180830' got nothing.


Thanks!

    Hi @aryer

    There are 2 topics:

    Hi @aryer

    I think you can request data in range to cover the date which you want and look for the next available data point if that data point is missing.

    This is an example:

    result.jpgI got the result for '015351109' from 2018-01-01,EDate=2019-01-31 using the following function:

    df,e = ek.get_data('015351109',['TR.PE(SDate = 2018-01-01,EDate=2019-01-31,Frq=D).Date','TR.PE(SDate = 2018-01-01,EDate=2019-01-31,Frq=D)'])

    Please check attached for results. And you can see that the data jumped from 2018-07-26 to 2018-10-25, from 50.45 to 105.59, without any data points in between.

    Could you let me know why this happened? Any methods to fix it?

    Thank you!
