I am using this command to get the total returns on a day for a range of dates:
ek.get_data(firms, fields = ['TR.TotalReturn1D.date','TR.TotalReturn1D'], parameters={'SDate':Start,'EDate':End,'Frq':'D','CH':'Fd'})
It works, but what does 'CH':'Fd' mean?
This is a parameter for the TR function in Eikon Excel.
Typically, it is used with RH (row headers). They are used to format the data displayed on the Eikon Excel, as shown below.
However, from my test, these parameters don't affect the result returned by Eikon Data APIs.
