Shade colour not being remembered

[Jellybean]

Hi

I have an indicator that draws a coloured region beteen Bollinger Band upper and lower series. I set the colour and opacity of the shaded region (and also the Bollinger Band parameters) via input parameters.

When I use the indicator on a chart with settings different from the defaults, all is OK until I close the workspace and re-open it. The colour reverts to the default colour even though the opacity and Bollinger Band parameters are remembered.

How do I get the setting for region colour to persist?

Cheers
Tony

Here are sections from the code:

private double numStdDev = 2;
private int period = 14;
private Color shadeColour = Color.CornflowerBlue;
private int shadeOpacity = 2;
...
protected override void OnBarUpdate()
{
DrawRegion( "Area", CurrentBar, 0, Bollinger( numStdDev, period ).Upper, Bollinger( numStdDev, period ).Lower,
shadeColour, shadeColour, shadeOpacity );
}
...
[XmlIgnore()]
[Description("Colour of the shading.")]
[GridCategory("Parameters")]
public Color ShadeColour
{
get { return shadeColour; }
set { shadeColour = value; }
}

Hello JellyBean,

Thanks for your post about color persistence.

In C#, which NinjaScript is based on, the colors must be serialized to retain their state when the program is shutdown, otherwise as you have observed all it knows is the default color.

Here is a link that states the purpose of serialization: http://msdn.microsoft.com/en-us/library/ms233843.aspx

I have copied your color part of the properties and added the needed serialization statements.

[XmlIgnore()]
[Description("Colour of the shading.")]
[GridCategory("Parameters")]
public Color ShadeColour
{
get { return shadeColour; }
set { shadeColour = value; }
}

[B][Browsable(false)]
public string shadecolourSerialize
{
get { return NinjaTrader.Gui.Design.SerializableColor.ToString(Shadecolour); }
set { Shadecolour = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
}[/B]
