Gottfried, I know it has some whipsaws right now, but I'm still fiddling with it. If you take a close look at the charts, I *think* you'll see that it shows definite promise.
Here is what's going on:
The blue line is a weighted, summed moving average of the 8, 13, 21, and 34 day ROC, (Rate of Change). The weightings are 1, 2, 3, and 4, for the 8, 13, 21, and 34 day ROCs, respectively.
The yellow line is an 8 day EMA (5%) of the blue line.
