If the triangle does complete as suggested, the only question will be whether it completes above or below the August high. The former will allow for the 4th wave interpretation to remain on the table while the latter will leave us with the more likely outcome that we are currently in the middle of a much larger triangle for wave [B] of x for the overall cyclical bull market. I suspect that we will see the latter outcome, but we won't know for sure for at least 3 more weeks.
The other valuable piece of information from this triangle is that it will invalidate the possibility of a flat/expanded flat correction. However, we will still have to be on guard for the development of a double zigzag for wave (C) down which is now underway that could extend well into January.
