Limitdown and TigerO, I don't use the 3 line break in preference to any charting method. I use it in conjunction with other study methods, Bollinger bands, candlestick patterns, etc. All timing methods have advantages and disadvantages as you well know. I like using the 3 line break because it's black and white. It tells you exactly when to get in and when to get out. (Based on your own parameters), and it defines the trend. You can make the 3 line break as sensitive as you want, right down to a five tick bar. There's always a trade off, however. The more sensitive the indicator, the more false signals you will get.
