1.This current wave 4-5 could end at the position/length of wave 0-1, creating a sort of "double bottom" appearance.
OR
2. It could travel 1.618 - 2.618, meaning that it could pierce directly through the neckline.
I think if you're looking at it from the perspective of big traders and money managers needing to get more contracts filled to maximise their profits on the way down then they will go for option 1 (Please see the link i posted for full analysis and explanation).
Option 2 seems too easy to see from the naked eye and the contracts look pretty balanced at the moment for long/short positions, hence not enough contracts for them.
