For some context:
Rule of alteration states that if/when W2 is a Flat then W4 can only be either zig zag or triangle.
W(4) "Guideline" (not a rule) :
When the 4th wave finishes its trajectory it is most commonly known the wave A will test the 2 of the wave 5 one degree less and wave C will end somewhere in the price area of wave4 one degree less.
If this ends up being a zig zag and not a triangle I would think this (4) will be utter destruction of the bulls.
