Fibonacci channel

There is no separate FibonacciChannelAnnotation class in scichart-financial-tools. The channel-like Fibonacci tool is the existing FibonacciRetracementAnnotation📘 configured with verticalOnly: false.

In that skewed mode, points 1 and 2 define the baseline, while point 3 defines the parallel channel direction. The result is both Fibonacci and channel-like: the levels remain Fibonacci levels, but the geometry can lean with the move instead of staying vertical.

Because this is still a FibonacciRetracementAnnotation, extendStart and extendEnd can project its skewed level lines and colored bands beyond either side. Note that by changing the X order of the 2 points (where point 1's X value is before point 2's X value), the extensions will flip from "start" to "end" and vice versa.

sciChartSurface.annotations.add(
    new FibonacciRetracementAnnotation({
        points: [
            { x: 4, y: 4 },
            { x: 7, y: 5 },
            { x: 8, y: 2 }
        ],
        verticalOnly: false,
        strokeThickness: 2,
        thresholds: [0, 0.382, 0.5, 0.618, 1, 1.618, 2.618],
        regionColors: ["#F59E0B", "#F97316", "#FB7185", "#60A5FA", "#34D399", "#A78BFA"],
        fillOpacity: 0.18,
        connectorLineStrokeDashArray: [6, 4],
        fibonacciLabelPlacement: EFibonacciLabelPlacement.Left,
        isEditable: true,
        isSelected: true
    })
);
tip

If you want a skewed Fibonacci channel, keep using FibonacciRetracementAnnotation and switch verticalOnly off. The same class becomes a 3-point channel-like retracement without needing a new annotation type.
