in order to retrieve the expiry/last trading date for a given future i have been using
df, err = ek.get_data( 'LCOK2^2', ['EXPIR_DATE', 'TR.FOFirstNoticeDay', 'TR.FOLastTradingDate'])
however for older RICs (older than 2010 , e.g. Jun 2005) it does not work. E.g. :
df, err = ek.get_data('LCOM5^0', ['EXPIR_DATE', 'TR.FOFirstNoticeDay', 'TR.FOLastTradingDate'] )
how can i get the expiry for these rics?
