Rules:
ZigZag is always a 3 wave structure.
Structure = 5-3-5
Wave B never move beyond the start of Wave A.
Wave B is subdivided into a three wave pattern: zigzag, flat, triangle or any combination thereof.
Wave A can be either an Impulsive wave or a Leading Diagonal.
Wave C can subdivide into 5 wave structures: a Diagonal or an Impulse wave.
Guidelines:
Waves A and C connected is usually parallel to the Line connecting the origin of the ZigZag to point B.
Waves A and C usually are Equal in length.
Wave A and C are more often subdivided into an Impulse Wave.
Wave C is always ended beyond Wave A.
Besides Waves A & C usually being equal, the ratios in a correction are less accurate than in an Impulse Waves 1,3 & 5.
