ES: Diagonal Triangle completes the move down?

Yeah, I'll be the first to admit: that alleged wave 4 is a problem. It doesn't look like a zigzag. And a trendline doesn't connect waves 2 and 4 in this rendition. But 1 > 3 > 5 and 2 > 4. If ES doesn't retrace for another lower wave below 3217.75, I gotta wonder if this is a diagonal triangle. Several people have called it a B-wave low. Probably is. We'll see.
