In this four-part series, we’ll expand the complex corrective sequence concept. In particular, we’ll present here a different corrective pattern combination.
The double and triple structure
Elliott, in his Treatise, presented the alternation concept. This concept is critical to understand the structure of corrective waves and combinations. Also, he defined three types of basic corrective patterns zigzag, flat, and triangle. Double and Triple Three are a combination of zigzag patterns, to label each leg, we use the X, Y, and Z labels. Where each reactive wave is labelled as X.
Until this moment, we said that a combined structure could present a zigzag, a flat, and a five waves structure. But Prechter and Frost allow a triangle structure as a valid ending pattern. The following chart shows an example of a combination of a zigzag, a flat, and a triangle.
The difference between A-B-C and W-X-Y
An A-B-C structure is a simple corrective sequence like a zigzag, or a flat, it is a 5-3-5 or a 3-3-5 formation. However, a W-X-Y structure is a combination of two simple corrections (3-3-3). The A-B-C sequence has three swings; conversely, W-X-Y structure has seven swings.
Consider that it is common to find the A-B-C sequence as a zigzag pattern but no rule commands this argument.
