Hello everyone

I would like to get a time series with get_data. I would like to have the P/E ratio of the last 3 years.

I use the following code:

import refinitiv.data as rd rd.open_session() df = rd.get_data( universe = ['LISN.S'], fields = ['TR.PE'], parameters = { 'SDate': '2020-12-31', 'EDate': '-1D', 'Frq': 'D' } ) display(df)

I also get the P/E of the last 3 years, but I don't get any dates. I had this problem before and I was told that I just have to add *.fperiod*. But this does not work with TR.PE.

What do I have to do so that when I work with a start and end date, the date is always displayed.

Many thanks
