I just read Ehler's article (Stocks & Commodities V. 39:10 (20–23): Cycle/Trend Analytics And The MAD Indicator) and decided to modify his original idea a bit by taking the volume into account. Ehlers' "MAD indicator" compares two averages of different lengths, but this script compares two different averages (SMA and New WMA, weighted by volume) with the same length. Simple, but seems to be quite efficient on symbols with decent volume. Enjoy.
