Draw.ArrowUp/Draw.ArrowDown

[dmking]

In looking at the Draw.Arrow function, I'm wondering how to control the size of the "Arrow", also, I would like to control where the arrow is placed (instead of on the bar, have the arrow drawn where an event takes place, say where %K crosses %D, and offset from the crossing by some amount). I hope tthis makes sense.

Thanks

Hi dmking, thanks for your post.

The Arrow chart markers have a static size. If you need variable size arrows one would need to do custom drawing in SharpDX. To have an arrow draw on a condition you would need to wrap the Draw.ArrowDown() method within an IF statement with the condition e.g.

public class MyCustomIndicator : Indicator
    {
        private Stochastics Stochastics1;

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                ...
            }
            else if (State == State.Configure)
            {
            }
            else if (State == State.DataLoaded)
            {                
                Stochastics1                = Stochastics(Close, 7, 14, 3);
                Stochastics1.Plots[0].Brush = Brushes.DodgerBlue;
                Stochastics1.Plots[1].Brush = Brushes.Goldenrod;
                AddChartIndicator(Stochastics1);
            }
        }

        protected override void OnBarUpdate()
        {

            if (CurrentBars[0] < 1)
                return;

            if (CrossAbove(Stochastics1.K, Stochastics1.D, 1))
            {
                Draw.ArrowDown(this, @"DownArray " + Convert.ToString(CurrentBars[0]) + @" ", false, 0, (High[0] + (10 * TickSize)) , Brushes.Red);
            }

        }

Please let me know if I can assist any further.
