TriangleContr This pattern has been defined as a complex Corrective Pattern in which all waves are corrective and the trendlines converge. It is a very common corrective pattern,which takes the form of a sideways correction. triangles mostly occur in wave4 or B ,sometimes in wave X . this will be followed by strong thrust . the most likely price target for the followed is the width of the converging channel at wave B added to wave E ;
