Once the cash gap is filled at 2709, then the next hurdle will be 2745. There could be a pullback to close today's gap of 2686, but I believe we'll challenge 2745.
The good news is that a lot of stocks especially financials have already filled their morning gaps and are moving northward, so it's not at all a given that the full index will have to fill it's gap.
Personally, I would like the move to end right here at 2707 and pullback to the 2680 line over the next few days. And then have a full on move upwards.
