Hourly count on the preferred has the ES in a minor W4 (red numbers) to the drop from the Mar 27 high. Minor W2 was a simple zig-zag, so Minor W4 needs to be a flat, triangle or some sort of complex structure. Unfortunately the point at which a rally would invalidate this count under Elliott rules is at the bottom of Minor W1 (red), which is way up at 1386.25. However, as a practical matter a continuation of this rally with enough steam to bring those levels into view would make this count dubious.
