need to be out by next friday. Should be out by thursday to be sure, Settles in cash so i wouldn;'t worry about delivery
I once held an oil futures contract too long and got a delivery of 100bls of Brent Crude to my apartment. Turn on those computers!
6/16 is the last trade date. If you own the contract after the close on 6/16, you will be delivered against. You can roll it beforehand though. The CME has a calendar spread market that trades in 1/5 ticks and is extremely liquid.
