The Elliott wave rules - corrective waves

Corrective waves is the movement against the trend ( consolidation or letter phases). It is more difficult to identify than the motive wave because the corrective waves have more variations. The complexity of corrective waves can increase or decrease without warning, so the extend and depth of corrective waves are less pridictable than impulse waves.

 Corrective wave basic patterns:

Basic forms: Zigzag (5-3-5), flat (3-3-5), irregulars(3-3-5) and  triangles(3-3-3-3-3).

Complex forms: double threes and tripple threes ( this corrective forms can be subdivided into 4 categories: zigzag complex, flat complex, irregular complex).

Double threes patterns:

Tripple threes patterns:
