I am trying to run the below formula in Python.
start_date = str(20140901) end_date = str(20140701)
data, error = eikon.get_data("GBSN.PK", "TR.ClosePrice.calcdate",
{"SDate":start_date, "EDate":end_date} )
data
Unfortunately, it return an empty dataframe. If I change the start_date to str(20150101) or any later date, it works fine and I do see data for the time period between July and September 2014.
Why is the formula not working for this specific time period?
