I'd like to download cumulative volume and Open Interest (i.e. across all the maturities) for LCO, CL, RB , HO and LGO futures and the respective exchange traded pairs. I know that for LCO and LGO there are the rics LCOTOT and LGOTOT exactly for that purpose, but I'd like to find a way to download :
1) Cumulative volume for:
- HO
- RB
- CL
- all the pairs (e.g. LCOc1-LCOc2 + LCOc2-LCOc3 + etc..)
2) Cumulative Open Interest for:
- HO
- RB
-CL
- all the pairs (e.g. LCOc1-LCOc2 + LCOc2-LCOc3 + etc..)
thank you very much
