Here is a five minute bar chart of today's e-mini trading. My earlier suspicion that the day's high had been made proved wrong. While today was a low volume up day, I think the market has to go still higher to find enough sellers to produce a reaction of as much as 40-50 points.
My revised range estimate for today which I showed you when the market first hit 762 is the blue rectangle. The green rectangle is my current estimate for tomorrow's range. I think it will be about as big as today's. Its high should be near 783 and its low near 758 which is also the midpoint of today's range (red dashed line). The Federal Reserve announcement is due at 2:15 pm tomorrow but while it will produce a little more volatility when it comes out I don't think it will end up affecting the market's trend at all.
