TRIANGLE Triangles are corrective patterns that correct impulsive move, they consist of five waves a-b-c-d-e. They have three sub-waves in each structure (3-3-3-3-3). How to draw a triangle we need to connect wave A with C and wave B with D. Triangle is found in the position of wave 4, wave B of A-B-Correction, or in wave X in double zig-zags (W-X-Y) or triple zig-zags (W-X-Y-X-Z). Triangles usually tell that the price will move in the dominant trend once more.
