Serialize color error into condition builder

[marynja]

Hi!

I serialize a public Color in an indicator for can choose in parameters. Its ok, but when i call the indicator properties from conditions builder of strategies wizard the color shows as a string in quotes:

For ex: 'Color [DodgerBlue]'

and i need to select other color, and change to DodgerBlue

If i dont change the strategy compilation launch an error.

Its possible to avoid this issue?
more better, its possible to avoid all unnecessary parameters in condition builder?

THank you



My code:

Declaring colors:

private Color longsignalcolor = Color.DodgerBlue;
private Color shortsignalcolor = Color.Magenta;


Into properties:

//Color shortsignalcolor
[Description("Color for short signal arrow")]
[GridCategory("Parameters")]
public Color ShortSignalColor{
get { return shortsignalcolor; }
set { shortsignalcolor = value; }
}
// Serialize our Color object
[Browsable(false)]
public string ShortSignalColorSerialize{
get { return NinjaTrader.Gui.Design.SerializableColor.ToString( ShortSignalColor); }
set { ShortSignalColor = NinjaTrader.Gui.Design.SerializableColor.FromStrin g(value); }
}

marynja,

Please see the following for more information on how to fix that, basically you are missing a piece of XML code which is outlined at the link below.

Thanks Adam. i am using the [XmlIgnore()] before Color declaration but dont work.

If i write [XmlIgnore()] before Serialize instead of the Color declaration (as in your example), the problem its the same but the value now show as this: 'Color [Empty]'

Some idea? Thanks again

I instaling the example indicator and call into Condition Builder.
Please, look the image and how the wizard tak a string value for color. If i finish the wizard launch an error on generating the strategy.

Hello marynja,

You could receive an error for two reasons using the SampleColorInput.

1. SampleColorInput does not contain a Plot() which is going to be needed since you are comparing it to a value. So you may receive the following error: "'System.Drawing.Color' is a 'type' but is used like a 'variable'"

2. When you are choosing a color(s) you would want to use the "Web" tab to be able to select a color for your strategy. See attached image.

Let us know if we can be of further assistance.

I kown JC, and thanks.

If i select a web color, then the strategy compile correctly.

But maybe i dont explain well. I dont understan why i need to correct this error all the times when i use my indicator in the strategy wizard. When i declare the color is a web color.

I know that isnt a plot(), and i dont need in my strategy, is for it i want to hidde into Condition Builder.

Its possible to hidde this useless params? or its possible the initial color value be correct as same as i select a web color?

Thanks again

Hello marynja,

This is because the Strategy Wizard was not designed to handle color inputs. If you do not want to have it as a select able parameter you may want to create another indicator that does not need to take a color as a parameter that needs to be passed to it.

Happy to be of further assistance.

All right JC, thank you for it.

I pray to NT developers to fix this bug for new versions.

Thank you, happy day.
