    Methods

    • Rolling Aroon Down.

      Parameters

      • lows: number[]

        Low prices.

      • period: number

        Lookback length.

      Returns number[]

      Aroon Down per window.

      If period > lows.length.

    • Rolling Aroon Indicator.

      Parameters

      • highs: number[]

        High prices.

      • lows: number[]

        Low prices.

      • period: number

        Lookback length.

      Returns [number, number, number][]

      Array of [aroonUp, aroonDown, oscillator].

      If lengths differ or period > length.

    • Rolling Aroon Oscillator (element-wise aroonUp - aroonDown).

      Parameters

      • aroonUp: number[]

        AroonUp series.

      • aroonDown: number[]

        AroonDown series.

      Returns number[]

      • period: number

        Lookback length.

      Returns number[]

      Aroon Up per window.

      If period > highs.length.

    • Directional Movement System (+DI, -DI, ADX, ADXR).

      Parameters

      • highs: number[]

        High prices.

      • lows: number[]

        Low prices.

      Returns [number, number, number, number][]

      Array of [+di, -di, adx, adxr].

      If lengths differ, empty, or not enough data (len < 3*period).

    • Rolling Parabolic Time Price System (Wilder's SAR variant). Handles trend switches and AF updates internally, returns SAR per bar.

      Parameters

      • accelerationFactorStep: number

        AF increment.

      • startPosition: Position

        Long or Short.

      • previousSar: number

        Previous SAR seed (0.0 if none).

      Returns number[]

      SAR values per bar.

      If inputs empty or lengths differ.

    • Rolling True Strength Index (TSI).

      Parameters

      • prices: number[]

        Prices.

      • firstConstantModel: ConstantModelType

        First smoothing model.

      • firstPeriod: number

        First smoothing period.

      • secondConstantModel: ConstantModelType

        Second smoothing model.

      • secondPeriod: number

        Second smoothing period.

      Returns number[]

      TSI per window.

      If prices is empty or too short (len < first+second).

    • Rolling Volume Price Trend (VPT).

      Parameters

      • prices: number[]

        Price series (length L).

      • volumes: number[]

        Volume series (length L or L-1). If same length as prices, the first volume is skipped.

      • previousVolumePriceTrend: number

        Seed VPT value.

      Returns number[]
