We then had a three wave counter trend rally today. That would be indicative of a single zigzag retrace. However if this is wave (ii), it would be preferable if prices retraced deeper upwards. Therefore a double zigzag to fulfill a higher price pattern would make sense here.
So bulls best chance is to follow through on an inverted head and shoulders pattern.
A look at the daily SPX shows today's bearish price action. After rallying to close the gap down, stocks were weaker into the close. The daily price closed beneath the July 2011 and recent April pivot support of 1356-1357.
