Yeah, I noticed that, too. I don't blame you. I go away for a while, sometimes. The Dec. contract is the front month.
I like your idea of just holding and rolling, which I am thinking of doing in the equity indices. But I could never see that working in CL due to the special machinations of the crude market. The supply and demand constraints on Crude are major. Hell, the thing is down $2 since last week. So many variables, ug. I wish I had the mind to try the calendar spreads on it again, but I'm 9 months out from my last CL study. Good luck and fortune to you B1S2!
