I think It's only random up to the point where they trap buyers or sellers, once that is accomplished there's not much random left, way more often than not they are going to squeeze them out, at minimal to the next closest relative low or relative high.
If want to debate that it's still moving up and down in random waves, prior to taking out the relative low or high, then that's fine... and makes sense, but it's not like it takes some huge crazy path(generally speaking) once the trap is set in motion, it's normally pretty fast and straightforward(from a view of getting to the relative low or high without too much hassle).
