Thanks for the comments/thoughts.
I think I will sit tight for a couple of days and keep a close eye on things.
The Dec. contract is essentially all done but trading volume is still about half on F.
At the moment there is also a 16 cent price differential Z to F. I want to see how this plays out as F becomes the front month.
EIA report also comes out early this week, (noon Wed.) so I think I'll sit that out and see how things develop.
