SPX 1 min chart:
This close up shows the count as incomplete, but what I have as wave (3) could easily be wave (5) and the end of the second zig zag, as labelled in the earlier chart. I think we have to take out the wave (1) of [C] high at 1077.95 without making a new high to invalidate the count shown since wave (4) of [C] can't end below that level.
