Triangles and ending diagonal triangles always try to hide their hands. A careful count however can aid things.
Its still entirely possible the whole mess since last year counts as a massive ending diagonal triangle. Ending triangles are labeled internally [a]-[b]-[c] - (using Minuette degree for my explanation because the chart below is labeled as Minuette degree for the internal structures).
Ending Diagonal Triangles represents the market's inability to continue producing clean 5 wave impulse patterns up. The loss of momentum gets sluggish at the top is the theory. There is still overall five waves for the ending diagonal triangle however, waves 1,3, and 5 internally will be labeled 5-3-5, [a]-[b]-[c] zigzags. The correction waves 2 and 4 should also be labeled 5-3-5, [a]-[b]-[c] zizgags.
This chart below is labeled in accordance with the guidelines described above.
Overall the Wilshire might count like this:
