"B waves are phonies. They are sucker plays, bull traps, speculators' paradise, orgies of odd-lotter mentality or expressions of dumb institutional money (or both)...

X waves and D waves in expanding triangles, both of which are corrective wave advances, have the same characteristics." pg.81: Wave Personality - Elliot Wave Principle. by Frost and Prechter.
