Trends, Support and Resistance, Head and Shoulders, Double Tops and Bottoms, Line and Saucers Formations, V Formations, The Measured Move, The Coil, Continuation patterns, Reversal Days, Gaps, and Islands,and Moving Averages [the Elliott Wave "inventor" published his book in 1938, called "The Wave Principle" - that's a loooong time ago!!] Have there been any advances of late; and how do these advances make it to people who use it?? What's new??
