If we take out today's current high at 1032.95, invalidating the count I posted earlier showing a complete double zig zag, this may be what we are seeing:
SPX 1 min - single zig zag in progress:
Note: we may still be in the (Y) wave of [B], so taking out what I have as the [B] wave low won't necessarily invalidate this count. Only taking out the low from yesterday at 1010.91 without making a new high first will invalidate it.
