Primary wave 3 is a clearly extended wave, Primary wave 5 would be less likely to extend (although still possible).
We also know wave 4 often divides the entire impulse wave into Golden Section. When wave 5 is extended, this ratio is 0.618; when wave 5 is not extended, this ratio is 0.382.
Therefore, we could set $148 (approximation) as our initial target.
Looks like a diagonal is in the making
