Tom, I agree. Also, FWIW, I think NDR's use makes more sense. I've played (rather extensively) with Pring's system and found that it has so much lag to the indicator lines that the market is often going into a reversal by the time the thing gives a signal.
With the NDR method you aren't looking for signals, merely relative trend strength, so that shouldn't be a problem.
Please keep us updated on what you come up with.
