Get History Beta - Get_Data Function

victor.koyama

Hello,

I'm trying to retrieve the history for the 180D, 90D and BetaWklyAdj2Y indicadors from the TR.WACCBeta function. Currently, I've been able to set the date interval and frequency for the query. However, I have no idea how I can select the different indicators mentioned above. So far, I managed to build the following statment:

ek.get_data(stock_list,'TR.WACCBeta',{'SDate':'2020-05-22', 'EDate':'2020-05-29', 'FRQ':'D'})[0]

How can I adapt the function above to retrive the data desired?

Obs: I've tried to use the 'TR.BetaDaily180D','TR.BetaWklyAdj2Y','TR.BetaDaily90D' functions. However, they are not allowed to retrive data historically.

Hello @victor.koyama,

I use Data Item Browser to confirm what content fields are available for the instrument, and what parameters are supported.

Within Eikon desktop I run Data Item Browser and examined, for IBM.N TR.WACCBeta field:

It allows for various time intervals in the parameters, for example, quarterly

ek.get_data('IBM.N',['TR.WACCBeta'],{'SDate':0,'EDate':-4,'Frq':'FQ'}

Resulting in

(  Instrument      Beta
 0      IBM.N  1.295649
 1      IBM.N  1.336528
 2      IBM.N  1.325593
 3      IBM.N  1.251175
 4      IBM.N  1.232000, None)

The other fields that you mention, 'TR.BetaDaily180D','TR.BetaWklyAdj2Y','TR.BetaDaily90D' do not support the same parametrization, so you can only retrieve only single, current value

So I think what you see is consistent with what is currently supported?
