• Impulse wave subdivide into 5 waves. In Figure 2, the impulse move is subdivided as 1, 2, 3, 4, 5in minor degree • Wave 1, 3, and 5 subdivision are impulse. The subdivision in this case is ((i)), ((ii)), ((iii)), ((iv)), and ((v)) in minute degree. • Wave 2 can’t retrace more than the beginning of wave 1 • Wave 3 can not be the shortest wave of the three impulse waves, namely wave 1, 3, and 5 • Wave 4 does not overlap with the price territory of wave 1 • Wave 5 needs to end with momentum divergence
