In a Triangle, the waves always subdivide into 5 waves: A, B, C, D, & E. Wave A never goes beyond the origin or point X. Structure = 3-3-3-3-3 At least four of the five waves subdivide into a zigzag or a combination of zigzags. Triangles do not have more than one complex subwave (only one Double or Triple). One of the five waves can subdivide into an Impulse In a Barrier Triangle, Wave C never goes beyond Wave A, & Wave E never moves beyond C. In a Barrier Triangle, Wave D ends around Wave B, forming a straight flat line or Barrier. Guidelines:
Wave B may go beyond the start of Wave A; it is not common and it is called a Running Triangle. A Wave 5 following a Barrier Triangle can either be sharp, short and brief; or turn into an Extended Wave 5. Barrier Triangles are less common than a Contracting Triangle.
