As a final note: I would note that closing this setup out for a 700/contract profit or so isn't as "sexy" as it looks, since it was not an "original" setup. It involved a couple of rolls that I got credits for, but when you roll an underwater side, you realize a loss for that, so it's important to paw through your trade chain from beginning to end, making sure that you're exiting profitably or at least for less of a loss than you would have experienced were to have just shut the whole thing down ... . Otherwise, you may be exiting the current setup profitably but not net profitable for the original setup plus any rolls you've done ... . In this particular case (and without posting the entire, drawn out trade chain), I netted something in excess of what my profit target for the original setup was, which was far less "sexy" ... .
