SPX breached an 11-week channel (discussed previously) and closed solidly below but on its rising SMA50 and the long-term gray line which connects prior peaks (Chart 1).
The rally since the past March could be complete as a triple zigzag (Chart 1), with (Z) about 50 index points longer than (Y) which is not ideal.
If there is one more upswing (Chart 2 discussed previously), SPX is likely to overlap the green A at 3645.99 first.
Short term, SPX kissed the underside of an EDT and fell (Chart 3). On Friday, a small degree up wave kissed the underside of the gray line and fell.
