Cycle Line Colors

[stockgoblin]

Hi,

I have an indicator that draws some lines when a condition is met in a loop. I don't want a million lines so I put in a counter to limit the number of tags "n" and thus lines. Now, I would like those lines to be different colors each time they are made. So, I declared some private ints:

     private Color CrossColor1 = Color.Red;
		private Color CrossColor2 = Color.White;
		private Color CrossColor3 = Color.Blue;
		private Color CrossColor4 = Color.Green;
		private Color CrossColor5 = Color.Gold;
		private Color CrossColor6 = Color.Fuchsia;
		private Color CrossColor7 = Color.Cyan;
		private Color CrossColor8 = Color.Gray;
		private Color CrossColor9 = Color.Lime;
		private Color CrossColor10 = Color.DarkOrange;
		private Color CrossColor11 = Color.Purple;
		private Color CrossColor12 = Color.HotPink;

and put in another counter "c":

             n++;
			c++;
			DrawExtendedLine("Parallel1" + n, false, 1, Close[1], 0, Close[0],("CrossColor" + c), DashStyle.Dash, 1);
			DrawExtendedLine("Parallel2"+ n, false, i+2, Close[i+2], i+1, Close[i+1], ("CrossColor" + c), DashStyle.Dash, 1);
			if (n>42)
			n=0;
			if (c>12)
			c=0;

I just don't know how to refer to these colors in the DrawExtendedLine syntax. It was easy with the tags: "Parallel1" +n

but how do I do it with the Color option:

("CrossColor"+c) ?????


OR... is there an easier way to accomplish cycling the color of a line than using a counter like I'm trying to do?

Thanks for any help.

Hello stockgoblin,

Thank you for your post.

I am investigating how to do this on my end, I will follow up with you shortly on my findings.

Thanks for any help.

Put your defined colors in a List<> and refer to them by index.

Hello stockgoblin,

Thank you for your response.

The following is an example of using a list for the color of a horizontal line:

List<Color> colorList = new List<Color>();
			colorList.Add(Color.Blue);
			colorList.Add(Color.Red);
			
			int i = 1;
			DrawHorizontalLine("Test", Close[0], colorList[i]);
			i++;

Make sure to set the following under Using Declarations:

using System.Collections.Generic;

Please let me know if I may be of further assistance.

Got it. Thanks!
