DrawRegion colors disappear when I restart

[ntfred]

Hello,

I built an indicator which works well, all calc bugs removed as far as I know...
- see 1st attached image

However, when I shut down NinjaTrader and then restart the next day the colors in the indicator plot disappear and everything is gray.
- see 2nd attached image

If I refresh the chart everything is still gray. I noticed if I edit the indicator parameters, the up color / down color inputs are EMPTY...
- see 2nd attached image

From there I can select a new color and it works... so it appears my set colors are being replaced with "empty" when I shut down (or start up)? Does anyone have any idea how to fix this?

        #region Variables
	private Color upColor = Color.YellowGreen;
	private Color dnColor = Color.DarkOrange;
	private Color lineColor = Color.Gainsboro;
	#endregion

				if (CurrentBar == 0)
					return;
				
				if (Values[0][0] >= 0)
				{
					DrawRegion("Zone" + CurrentBar, 1, 0, Values[0], 0, Color.FromArgb(8,upColor), upColor, 4);
					
				}
				else if (Values[0][0] <= 0)
				{
					DrawRegion("Zone" + CurrentBar, 1, 0, Values[0], 0, Color.FromArgb(8,dnColor), dnColor, 4);
				}

        #region Properties
	[Description("Up Color")]
        [GridCategory("Parameters")]
		[Gui.Design.DisplayName ("\tUp Color")]
        public Color UpColor
        {
            get { return upColor; }
            set { upColor = value; }
        }
		
        [Description("Down Color")]
        [GridCategory("Parameters")]
		[Gui.Design.DisplayName ("Down Color")]
        public Color DownColor
        {
            get { return dnColor; }
            set { dnColor = value; }
        }
        #endregion

If you want your colors to persist across restarts, then you have to serialize them.

If you search the forum for the phrase: "serialize color", you should eventually come upon this thread: http://www.ninjatrader.com/support/f...ead.php?t=4977

It worked! Thanks for the help koganam, I really don't think I would have figured that one out on my own.

For anyone interested, here's what the new serialized code looks like:

        [COLOR="blue"][XmlIgnore][/COLOR]
	[Description("Up Color")]
        [GridCategory("Parameters")]
	[Gui.Design.DisplayName ("\tUp Color")]
        public Color UpColor
        {
            get { return upColor; }
            set { upColor = value; }
        }
	// Serialize Color object
	[COLOR="blue"][Browsable(false)]
	public string UpColorSerialize
	{
		get { return NinjaTrader.Gui.Design.SerializableColor.ToString(upColor); }
		set { upColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
	}[/COLOR]
		
        [COLOR="blue"][XmlIgnore][/COLOR]
        [Description("Down Color")]
        [GridCategory("Parameters")]
	[Gui.Design.DisplayName ("Down Color")]
        public Color DownColor
        {
            get { return dnColor; }
            set { dnColor = value; }
        }
	// Serialize Color object
	[COLOR="blue"][Browsable(false)]
	public string DnColorSerialize
	{
		get { return NinjaTrader.Gui.Design.SerializableColor.ToString(dnColor); }
		set { dnColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
	}[/COLOR]
