Hi,
I'm trying to pull the historic beta timeseries of a stock using the Datastream API in Python.
In Excel I use this function:
=@DSGRID("TW:TSM","897E","2010-01-01","2020-01-01","M","RowHeader=true;TimeSeriesList=true;ColHeader=true;DispSeriesDescription=false;YearlyTSFormat=false;QuarterlyTSFormat=false","")
In Python I tried:
data = ds.get_data(tickers = "TW:TSM", fields = ["897E"], start = "2010-01-01", end = "2020-01-01", freq = "M")
But I get:
"$$ER: E100,INVALID CODE OR EXPRESSION ENTERED"
Appreciate your advice. Thanks!
