Methods

dispose

getName

  • Gets the indicator name.

    Returns string

    The indicator name.

setLineColor

  • Sets the color of the True Strength Index line.

    Parameters

    • newColor: string

      New line color as string, should be in HEX format e.g. #FFFFFF.

    Returns void

  • Sets the line width of the indicator.

    Parameters

    • newWidth: number

      New line width.

    Returns void

  • Sets the types of moving averages used to calculate the smoothings and the Signal line.

    Parameters

    • firstSmoothMovingAverage: MovingAverageType

      Moving average type for the first smoothing.

    • doubleSmoothMovingAverage: MovingAverageType

      Moving average type for the second (double) smoothing.

    • signalMovingAverage: MovingAverageType

      Moving average type for calculating the Signal line.

    Returns void

setName

  • Sets the name of the indicator.

    Parameters

    • name: string

      New indicator name.

    Returns void

setOffset

  • Moves the indicator from its calculated position forward or backward.

    Parameters

    • newOffset: number

      New offset value.

    Returns void

setPeriodCounts

  • Sets the various time period counts used to calculate the indicator.

    Parameters

    • pricePeriodCount: number

      The number of time periods used to calculate the price change (value - value n periods ago).

    • firstSmoothPeriods: number

      The number of time periods used to calculate the first smoothing.

    • doubleSmoothPeriods: number

      The number of time periods used to calculate the second (double) smoothing.

    • signalPeriods: number

      The number of time periods used to calculate the Signal line.

    Returns void

setSignalColor

  • 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

setSource

  • Sets which values the indicator calculations are based on.
