Stochastic is an Oscillator popularised by George Lane. This indicator produces two lines, the %D and the %K. The %K line is a moving average of the %D line.
The Stochastic Oscillator has 3 main input variables:
- %K periods - the number of bars used in the calculation
- %K Slowing Periods - used to define the initial smoothing of the %K line. A value of 1 is a fast Stochastic, while a value of 3 is a slow Stochastic
- %D periods - the number of bars used when performing the smoothing of the %K line
The parameter MA is optional and can be one of the following moving averages, SMA, EMA or WWS. This is passed to the indicator as a string. If no moving average is passed to the indicator, a SMA will be used.
Popular values for this indicator are 5,3,3. Returns the %K line in scalar context. In list context returns %K line and %D line.
Examples:
#returns the %K and %D lines into the $k and $d variables
my ($k,$d)=SS(5,3,3);
#returns the %K and %D lines into the $k and $d variables, using
#an EMA moving average in the Stochastic calculation
my ($k,$d)=SS(5,3,3,'EMA');
