Hi Grabber, I have been liking the idea behind the Stochastic Oscillator myself. http://stockcharts.com/education/What/IndicatorAnalysis/indic_stochasticOscillator.html I don't see why you could not take that formula and adjust it to use the 26 week average. You should get both a positive and negative percentage depending on where price and the average are in relationship to each other.
Come see me at Systematic Investing group #board-966 lets talk formula plans.
