Futures are presenting an interesting set up this morning should the cash S&P open where it looks like it may. Getting above yesterday afternoon's 1831.55 high may open the door to a test of 1837.20. Above 37.20 would considerably tilt the odds of new all-time highs. So today's open is quite important.
Lower prices would have been preferred, specifically 1816-1818, but you can't always get what you want.
