Hi khoshroomahdi,

Your arrows are set at the level you define i.e. Bars.HighPrices.Maximum(Period) and Bars.LowPrices.Minimum(Period)

            Chart.DrawIcon("iconName", ChartIconType.DownTriangle,GetHighLowInSelection().Point2.BarIndex, Bars.HighPrices.Maximum(Period), Color2);
            Chart.DrawIcon("iconName2", ChartIconType.UpTriangle,GetHighLowInSelection().Point1.BarIndex, Bars.LowPrices.Minimum(Period), Color2);

If you need them at a different place, you need to add/subtract distance accordingly.

Best Regards,

Panagiotis
