In Trade, a language of my own devising: Where x is a time series: Normalized Volume = volume(x) / average(volume(x), 50, simple) * 100 BandWidth = (upperBB(close(x), 20, 2) - lowerBB(close(x), 20, 2)) / midBB(close(x), 20) * 100 The numerically quick will note that BandWidth as specified is four times the coefficient of variation. > Tomorrow, will wrestle with Mandrake Linux machine and get > running there too.
