Elliott Wave (2) generally unfolds as a simple abc correction
In most cases Wave (2) usually unfolds as a simple ABC correction. Or put another way, a simple ABC correction is found in a Wave (2) correction more often than in a Wave (4).
Again, this is a very useful piece of information, because once Wave (1) is complete, then the most likely pattern to unfold is a simple ABC correction.
And, because of the rule of alternation, this leads onto Wave (4) usually being the complex correction in a completed 5-wave sequence.
