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)]0

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?0

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.
