Alligator

The Alligator was authored by Bill Williams. It is a combination of balance lines (Moving Averages) that use fractal geometry and non linear dynamics. They consists of 3 lines: Jaw, Teeth and Lips. Typically a smoothed moving average (SMMA) is used with periods/shifts of (13/8, 8/5, 5/3) for the lines respectively. 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

Plot1: jaw = ma(method, index + jawShift, input, jawPeriod);
Plot2: teeth = ma(method, index + teethShift, input, teethPeriod);
Plot3: lips = ma(method, index + lipsShift, input, lipsPeriod);
