call to get_data returns either open interest data or other fields data but not all at the same time

@ chavalit.jintamalit Can you check with your colleagues? It makes no sense that

DSPLY_NAME, PUTCALLIND, STRIKE_PRC, CF_CLOSE, IMP_VOLT and EXPIR_DATE

come from realtime data as those are not realtime data by nature.

I should be able to display all of the above along with the open interest data at close each day.

I'm certain this is possible, could you please check further?

Running the call to get_data below, as of today (16/10/2020):

data_temp, err = ek.get_data(instruments = 'TFMB1900N1', \
                             fields = ['DSPLY_NAME',\
                                       'PUTCALLIND',\
                                       'STRIKE_PRC',\
                                       'CF_CLOSE',\
                                       'TR.OPENINTEREST(-1m)',\
                                       'TR.OPENINTEREST(-1m).Date',\
                                       'EXPIR_DATE'])

Returns:

Why is the date 31/08/2020? That doesn't see to be 1 month ago.

How should I edit the call to get-data above to retrieve open interest for that RIC as of a month ago?

Thanks
