Currency Times Series Python API

Hello,

I am using the below formula to download a data frame of daily price quotes for a list of currency rics:

df_cy = pd.DataFrame(ek.get_timeseries(list_rics,['CLOSE'],start_date = first_date,end_date = last_date))


It seems that I am limited to 1 month of data with this formula.


How to have the same result, but for a longer timeperiod?


Thanks in advance.
