sc
A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
extremeLow
This is the level at which the Stochastic is believed to indicate an oversold level. The Stochastic always lies between 0 and 100, and a suggested extreme low value to take is 20.
extremeHigh
This is the level at which the Stochastic is believed to indicate an over brought level. The Stochastic always lies between 0 and 100, and a suggested extreme high value is 80.
noOfPeriods
An integer which represents the number of periods used over which the closing price is compared.
method
Determines the methods used for the evaluation of the moving average in accordance with the following key:
  1. 1 = Simple moving average
  2. 2 = Geometric moving average
  3. 3 = Linearly weighted moving average
  4. 4 = Exponentially Weighted Moving average within smoothing fact set to be 0.5.

For further details concerning the definition of these moving averages please see the accompanying PDF documentation or the API documentation for SimpleMovingAverage.

lengthOfMA
The number of periods over which the moving average is considered.
Implements a general framework for producing extreme value trading signals using Stochastic indicators.

  4. 4 = Exponentially Weighted Moving average within smoothing fact set to be 0.5.

lengthOfMA
The number of periods over which the moving average is considered.

Return Value

-1, 0, 1 - this method returns either -1, 0, 1 to indicate that either a sell, no action or buy signal was generated.

Remarks

Note, that the general ides of this approach is to seek points which are oversold or over brought levels which are turning.

Methodology

Buy when the Oscillator the Stochastic %D falls below a specific level (e.g. 20) and then rises above that level. Sell when the Oscillator rises above a specific level (e.g. 80) and then falls below that level. This approach is the preferred method of the Stochastics original creator George Lane.
