GpuDirectionalIndexCalculator

StockSharp.Algo.Gpu.Indicators

GPU calculator for Directional Index (DX, +DI, -DI).

Erbt von: GpuIndicatorCalculatorBase<DirectionalIndex, GpuDirectionalIndexParams, GpuDirectionalIndexResult>

Konstruktoren

public GpuDirectionalIndexCalculator(Context context, Accelerator accelerator)

gpuDirectionalIndexCalculator = GpuDirectionalIndexCalculator(context, accelerator)

Initializes a new instance of the GpuDirectionalIndexCalculator class.

context: ILGPU context.
accelerator: ILGPU accelerator.

Methoden

Calculate

public override GpuDirectionalIndexResult[][][] Calculate(GpuCandle[][] candlesSeries, GpuDirectionalIndexParams[] parameters)

result = gpuDirectionalIndexCalculator.Calculate(candlesSeries, parameters)

DirectionalIndexParamsSeriesKernel

private static void DirectionalIndexParamsSeriesKernel(Index2D index, ArrayView<GpuCandle> flatCandles, ArrayView<GpuDirectionalIndexResult> flatResults, ArrayView<int> offsets, ArrayView<int> lengths, ArrayView<GpuDirectionalIndexParams> parameters)

GpuDirectionalIndexCalculator.DirectionalIndexParamsSeriesKernel(index, flatCandles, flatResults, offsets, lengths, parameters)

ILGPU kernel: Directional Index computation for multiple series and parameter sets. One thread handles one (parameter, series) pair and iterates bars sequentially. Matches CPU algorithm: ATR = WilderMA(TrueRange), DI = 100 * WilderMA(DM) / ATR.
