Gator Oscillator

The Gator Oscillator (GO) was authored by Bill Williams. The GO is based on the Alligator, also written by Bill Williams. It shows the degree of convergence/divergence of the balance lines. The top bar is the absolute difference between the Jaw and Teeth lines. The bottom bar is the absolute difference between the Teeth and Lip lines (with a minus sign to display below 0). The user may change input (midpoint), method (SMMA), period and shift lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.

Calculation

//input = price, user defined, default is Midpoint
//method = moving average (ma), user defined, default is SMMA
//jawPeriod = user defined, default is 13
//jawShift = user defined, default is 8
//teethPeriod = user defined, default is 8
//teethShift = user defined, default is 5
//lipsPeriod = user defined, default is 5
//lipsShift = user defined, default is 3
//index = current bar number, abs = absolute value

jaw = ma(method, index + jawShift, input, jawPeriod); 
teeth = ma(method, index + teethShift, input, teethPeriod); 
lips = ma(method, index + lipsShift, input, lipsPeriod); 
PlotHist1: top = Math.abs(jaw-teeth);
PlotHist2: bottom = -Math.abs(teeth-lips);
