JC - MM's don't like opening gaps. They have to take the opposite side to cover the opening positions. That's why most gaps fill and those that don't by late morning usually keep going.

They are trying to keep as a low a gap as possible and I'd look for an effort to fill it. Once that is done.....

This letter says basically the same thing as the outdated PR we were debating as the cause yesterday, and we all know where the price was back then.
