    {
        protected override void Initialize()
        {
            Chart.DrawVerticalLine("Dots", Chart.LastVisibleBarIndex, Color.Red, 3, LineStyle.Dots);
            Chart.DrawVerticalLine("DotsRare", Chart.LastVisibleBarIndex - 2, Color.Yellow, 3, LineStyle.DotsRare);
            Chart.DrawVerticalLine("DotsVeryRare", Chart.LastVisibleBarIndex - 4, Color.Green, 3, LineStyle.DotsVeryRare);

    }
}

class LineStyleSample():
    def initialize(self):
        api.Chart.DrawVerticalLine("Dots", api.Chart.LastVisibleBarIndex, Color.Red, 3, LineStyle.Dots)
        api.Chart.DrawVerticalLine("DotsRare", api.Chart.LastVisibleBarIndex - 2, Color.Yellow, 3, LineStyle.DotsRare)
        api.Chart.DrawVerticalLine("DotsVeryRare", api.Chart.LastVisibleBarIndex - 4, Color.Green, 3, LineStyle.DotsVeryRare)
        api.Chart.DrawVerticalLine("Lines", api.Chart.LastVisibleBarIndex - 6, Color.Blue, 3, LineStyle.Lines)
        api.Chart.DrawVerticalLine("LinesDots", api.Chart.LastVisibleBarIndex - 8, Color.Magenta, 3, LineStyle.LinesDots)
        api.Chart.DrawVerticalLine("Solid", api.Chart.LastVisibleBarIndex - 10, Color.Brown, 3, LineStyle.Solid)

    def calculate(self, index):
        api.Result[index] = api.Bars.ClosePrices[index]
```
