this code just get one future expire date
req, err = ek.get_data(['STWc1'], ['EXPIR_DATE'])
But How to get the history expire date form 2015-01-01 to 2018-08-30?
@andy.ej I am afraid we do not store the expiration date series, and the EXPIR_DATE real-time field does not have an equivalent either on the time series or fundamental database. The contract specification (here) says "LAST TRADE DATE - Second last business day of the contract month".
I am attaching a sample calculation file using this logic for Eikon Excel.
