Thinkscript AUGEN N-1

This is a handy script for the TOS platform that I found. It bascically shows Jeff Augen's standard deveation spikes.

Augen N-1

declare lower;

input length = 20;

def closeLog = Log(close[1] / close[2]);

def SDev = stdev(closeLog, length)* Sqrt(length / (length – 1));

def m= SDev * close[1];

plot spike = (close[0] – close[1]) / m;

spike.setPaintingStrategy(PaintingStrategy.HISTOGRAM);

spike.AssignValueColor(if close > close[1] then Color.UPTICK else if close < close[1] then Color.DOWNTICK else GetColor(1));
