Combination corrective wave pattern rule and guideline

The corrective may not end in one-pattern (Zigzag, Flat or Triangle), it will follows by other corrective patterns in series, aka Combination.

Combination may consist of Two or Three corrective patterns. The wave that link Two or Three pattern is called wave-X.

The are two types of combinations:

1. Double combination
   ABC-X-ABC or W-X-Y
2. Triple combination
   ABC-X-ABC-ABC or W-X-Y-X-Z
   (or W-X-Y-XX-Z)

Below is the example of combination wave patterns.
