It's a decision time for SPX. Path_1 would be the index is reaching possible B top and head down to test the low again for C wave, Path_2 would be retrace about 50-60% for 1-2 down and head up. This path would create an Inverse H&S shown in pink circle. Path_3 would be a more complex triangle 4th.
It's possible to top in V as marked or expandable flat B.
IF so, a lot of people will be caught off guard next week open.
