Hello I want to export all option contract information of the future CTZ6. I actually see two maturities related. However I use the below codes to extract I can only have one code exported. ld.get_data('0#1CTZ6+', fields= ['PUTCALLIND', 'STRIKE_PRC', 'CF_BID', 'CF_ASK', 'CF_CLOSE', 'IMP_VOLT', 'CF_VOLUME','EXPIR_DATE'])
