Returns the same values as the NT supplied ADX, but has at least a 12K memory advantage. Both do not iterate, so are reasonable to use with CalculateOnBarClose == false, although they are somewhat computationally intense. Version 1.0.
Adaptive Moving Average, from the book 'Smarter Trading' by Perry J. Kaufman. A range from slow to fast for EMA period is selected based on 'Efficiency' (a signal to noise ratio, see jhlEfficiency). The resulting EMA factor is then squared, which will bias the long end of the range towards zero movement (a 30 slow period becomes 479.5 periods when the EMA factor is squared). For any given slow period n, the effective maximum period is (n + 1) squared / 2 - 1. Version 1.0.
