A single zigzag in a bull market is a simple three-wave declining pattern labeled A-B-C and subdividing 5-3-5. The top of wave B is noticeably lower than the start of wave A, as illustrated in Figures 1 and 2.

Occasionally zigzags will occur twice, or at most, three times in succession, particularly when the first zigzag falls short of a normal target. In these cases, each zigzag is separated by an intervening “three” (labeled X), producing what is called a double zigzag (see Figure 3) labeled W – X – Y.

Key Takeaway: Zigzags are sharp corrections wherein wave B NEVER exceeds the origin of wave A.
