Zigzag Pattern


A Zigzag is the most common corrective structure, which starts a sharp reversal. Often it looks like an impulsive wave, because of the acceleration it shows. A zigzag can extend itself into a double or triple zigzag, although this is not very common, because it lacks alternation (the same two patterns follow each other). Notice that the zigzag can only be the first part of a corrective structure.

Rules and guidelines:

It is composed of 3 waves.
• Waves A and C are impulses, wave B is corrective.
• The B wave retraces no more then 61.8% of A.
• The C wave must go beyond the end of A.
• The C wave normally is at least equal to A.

In which wave

Most of the time it happens in A, X or 2. Also quite common in B waves as a part of a Flat, (part of) Triangles and sometimes in 4.

Internal structure

A single Zigzag is composed of 3 waves, a double of 7 waves separated by an X wave in the middle, a
triple of 11 waves separated by two X waves (see pictures below). The internal structure of the 3 waves is
5-3-5 in a single Zigzag, 5-3-5-3-5-3-5 in a double.

Example of a Double Zigzag

As you have noticed we have a more modern representation of the Double Zigzag using the labels WXY instead of ABCXABC. This is more consistent, since this way 2 zigzags of lower degree get connected to each other by waves of higher degree. On top if that, our automatic analysis needed such a consistent method of labeling to reach maximum performance. Instead of labeling 7 waves (ABCXABC), in our daily analysis we need to label only 3 waves (WXY). According to the same method a Triple Zigzag is represented by WXYXZ instead of ABCXABCXABC. This way the number of waves was reduced to five instead of eleven.
