Interestingly there are lots of NG contracts.
you can even trade NGZ32, ie contract that will expire 13 years from now.
I can see NG J27 contract with some open interest.
CL, NG, RB and HO are all like that. You can trade decades out in the future, on futures contracts in that sector. And if you put an order in at some price level you establish, I bet you'll get a fill!
