Here is a five minute e-mini bar chart for the past two day sessions. Earlier today I estimated that the low for the day would be near 753 (blue rectangle) and anticipating that low I put on a single unit long position at 755. I had also noted that the biggest rally on the way down from last Friday's high at 840.50 had been about 19 points (red rectangle). So when the market moved above 770 a little while ago I sold my longs a little above the top of the red rectangle.
The high volume on this rally suggests that a demand shock may be in progress, but it is too early to tell. If it really is a demand shock then I would expect the market to hold above 762 and finish the day strong. In any case a move above today's high - whatever it turns out to be - on Monday would be very bullish.
