The recent price action of the US Dollar Index (DXY) appears to me to be a excellent example of what in EWT is called an Ending Diagonal Triangle. In EWT normally the 5th wave is composed of 5 sub-waves that do not overlap. (Which in this example I have labeled .1,.2,.3,.4,.5). But in this type of ascending triangle formation they do overlap and each sub-wave often has an a-b-c appearance i.e. composed of 3 waves.
