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

setPeriodCount

setPeriodCount(newPeriodCount): void
Sets the overall number of time periods (lookup periods) used to calculate the indicator.
Parameters
- newPeriodCount: number
  
  New period count.
Returns void

setSignalColor

setSignalColor(newColor): void
Sets the color of the Signal line.
Parameters
- newColor: string
  
  New line color as string, should be in HEX format e.g. #FFFFFF.
Returns void

Sets the number of time periods used to calculate the Signal line.
Parameters
- newPeriodCount: number
  
  New period count.
Returns void

setSmoothingPeriodCounts

setSmoothingPeriodCounts(rawSmoothingPeriods, fisherSmoothingPeriods): void
Sets time periods used for smoothing before fisher transform and for EFT line.
Parameters
- rawSmoothingPeriods: number
  
  New period count for raw smoothing.
