Hi. Im trying to download historic options data. Ive found that I can open the data in Eikons chart app with the example ticker QHYGH171808500.U^H18
[for the ticker HYG -17Aug2018 strike 85]
but I cant seem to be able to access this data through Python
#--trying every possible header I can find for any result--
fields = ['DSPLY_NAME','EXPIR_CYCL','CF_DATE', 'TR.CLOSEPRICE', 'EXPIR_DATE', 'PUTCALLIND', 'STRIKE_PRC', 'CF_CLOSE','IMP_VOLT','CF_VOLUME','OPINT_1']
df = ek.get_data('HYGH171808800.U^H18',fields)
Not sure if I'm doing something wrong or if this is not possible.
If its not possible how do I download this through the Excel data stream?
