rd.get_history() getting data before start date

rics = 'ABB.ST'
start = '2020-01-01'
end = '2024-02-15'

rd.get_history(universe  = rics, fields = "TR.CompanyMarketCap", start = start, end = end)'

I am running the code above and the returned data is as below:

as start is 2020-01-01 why do I get data for 2019-12-30?

You can use the Python code to filter dates. For example:

rics = 'ABB.ST'
start = '2020-01-01'
end = '2024-02-15' 
df = rd.get_history(universe  = rics, fields = "TR.CompanyMarketCap", start = start, end = end)
df[(df.index >= start)]

Thank you for reaching out to us.

I used the same function in Excel and got the same result.

=@RDP.Data("ABB.ST","TR.CompanyMarketCap.Date,TR.CompanyMarketCap.calcdate,TR.CompanyMarketCap","Frq=D SDate=2020-01-01 EDate=2024-02-15 CH=Fd RH=IN",B3)

I assume that it may use the TR.CompanyMarketCap.Calcdate field for the query.

rics = 'ABB.ST'
start = '2020-01-01'
end = '2024-02-15'
 
rd.get_history(universe  = rics, 
               fields = ["TR.CompanyMarketCap.date",
                         "TR.CompanyMarketCap.Calcdate",
                         "TR.CompanyMarketCap"], 
               start = start, end = end)

Please contact the helpdesk support team directly via MyRefinitiv to confirm this.

So how should I adjust my code?

Hi @jn02 ,

For this field, the function seems to only use calc date as what it got from start-end parameters.

As this is also reflect in the Excel formula, you can contact the helpdesk support as mentioned by my teammate if they have any suggested workaround.

So I did not get an answer regarding my question about a work around
