Larger picture wave counts (Chart 1) - The top two counts say that today's sharp advance is EITHER (iii) of [c] of 2-up (GREY, near term bullish) OR (ii) of [iii] of 3-down (RED, bearish). Given the very deep retrace up, the burden is on the immediately bearish count to deliver tomorrow.
Using the Sept SPX mini, one notices that wave iii in Chart 2 is shorter than wave i. Thus, we are able to project a wave v cap of 1105.50 in the mini. Wave v is 0.618 x at 1097.86, which should narrowly save the bearish count where the mini cannot exceed 1099.25.
