Wave A in detail

This picture shows wave A of the overall flat. It is divided into 3 waves (A,B,C), which go together as a zigzag.
Zigzags are corrective movements showing a 5-3-5 structure:
Wave A : impulsive (1,2,3,4,5) / Leading Diagonal Triangle
Wave B : corrective (A,B,C) / exception : triangle (A,B,C,D,E)
Wave C : impulsive (1,2,3,4,5) / Ending Diagonal Triangle

Wave A is a leading diagonal triangle (waves 1 and 4 are crossing, which is only allowed in LDTs).
Wave B shows a triangle (A,B,C,D,E). In this case wave E is building a triangle ((A),(B),(C),(D),(E)) in the triangle. This is kind of a textbook pattern.
Wave C shows an impulsive movement (1,2,3,4,5) and hereby completes the zigzag.
