An ending diagonal serves as the top stone of an impulse (wave 5) or a zigzag (wave C), so let's find out more about an ending diagonal pattern.
The main rules for an ending diagonal
This pattern subdivides into five waves. Wave 2 never ends beyond the starting point of Wave 1. Wave 3 always breaks the ending point of wave 1. Wave 4 usually breaks beyond the ending point of wave 1. Wave 5 in the absolute majority of cases breaks the ending point of wave 3. Wave 3 can't be the shortest. Wave 2 can't be a triangle or a triple three structure. Waves 1, 3, and 5 form like zigzags.
