specifically i'm trying to do something like ek.get_timeseries(['S-BRZPAR-B1'],start_date='2005-01-01',fields=['CONTR_MNTH']) where the goal is to view the contract month referenced by 'S-BRZPAR-B1' over time
the spot quotes implicitly reference a future month period. the description is 'Yellow Soybeans Paranagua Brazil FOB Bid 1' - the '1' references either '1 month ahead', or '1st position', i think, so i'm trying to figure out which it is (same applies to S-BRZPAR-B[2-4].) how do i calculate the reference month from the trading date?
maybe this is more helpful - if i pull spot metadata (ek.get_data()) on the instruments below for 'CONTR_MNTH' and 'DATE_RANGE', i can see the data i'm looking for. I want to be able to look this data up on a historical basis (which, if it doesn't exist in your api, it definitely should):
Instrument S-BRZPAR-B1 S-BRZPAR-B2 S-BRZPAR-B3 S-BRZPAR-B4 CONTR_MNTH X X X F
DATE_RANGE OCT8 NOV8 DEC8 FEB9
