Class RainbowOscillator

Rainbow Oscillator is a trend-following indicator based on several recursive smoothings via moving averages of the price. The indicator finds the highest and lowest values among these averages and creates an oscillator and a bandwidth based on them.

Inherited from IndicatorBase.getName

setFillEnabled

setFillEnabled(fillEnabled): void
Sets whether the area between the high and low lines is colored.
Parameters
- fillEnabled: boolean
  
  Set true to enable fill.
Returns void

setLineWidth

setLineWidth(newWidth): void
Sets the width of the band lines.
Parameters
- newWidth: number
  
  New line width.
Returns void

setLookbackPeriods

setLookbackPeriods(lookbackPeriods): void
Sets how many time periods are checked when finding out the highest and lowest prices.
Parameters
- lookbackPeriods: number
  
  The number of lookback periods.
Returns void

setMovingAverageType

setMovingAverageType(movingAverageType): void
Sets the type of moving average used to calculate the smoothings.
Parameters
- movingAverageType: MovingAverageType
  
  Moving average type.
Returns void

setName

setName(name): void
Sets the name of the indicator.
Parameters
- name: string
  
  New indicator name.
Returns void

Inherited from IndicatorBase.setName

setOffset

setOffset(newOffset): void
Moves the indicator from its calculated position forward or backward.
Parameters
- newOffset: number
  
  New offset value.
Returns void

setOscillatorColors

setOscillatorColors(colorUp, colorDown): void
Sets the colors of the bars.
Parameters
- colorUp: string
  
  The color of the oscillator, when above zero value.
- colorDown: string
  
  The color of the oscillator, when below zero value.
Returns void

setPeriodCount

setPeriodCount(newPeriodCount): void
Sets the number of time periods used to calculate each moving average..
Parameters
- newPeriodCount: number
  
  New period count.
Returns void

setSmoothingLevels

setSmoothingLevels(smoothingLevels): void
Sets the number of times the oscillator is smoothed by calculating a moving average.
Parameters
- smoothingLevels: number
  
  The number of smooths.
Returns void
