Here is the example of complex wave calculation based on elliott wave principle.
Overall complex correction wave consists of 5 combined wave (w)-(x)-(y)-(x)-(z).
These complex correction played out for very long period time thus can be very confusing. (w) wave is a zigzag of a-b-c, followed by triangle a-b-c-d-e (x), another zigzag a-b-c (y), followed by flat...
