PlotColors serialization problem - NT7

January 30th, 2011, 06:25 PM

Hi,
I colored few indicators with PlotColors using Ninja help as an example. Every time I start the Ninja my colored indicators loosing colors, e.g. the rising, falling and neutral plots become transparent and I have to reset the colors in properties of the indicator. I'm not very good at programming in C# and there could be bugs in my code... Ninja provides very poor PlotColors example in online help. There is only one example on how to set static colors.
I'm attaching one of the indicators with call to PlotColors built in that loosing colors at start up. Is there an error in my code? I do not see it.
Thank you very much.

You need to serialize the colors:

Code

        // Serialize our Color object
        [Browsable(false)]
        public string FallingColorSerialize
        {
            get { return NinjaTrader.Gui.Design.SerializableColor.ToString(fallingColor); }
            set { fallingColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
        }

Add code like this for each Color in the indicator.

And now tell me, why you have put this in front of the section for the color serialization:

Code

[XmlIgnore()]

It is my understanding - I may be wrong - that this line will prevent the indicator from proper serialization, so if you store the indicator in a template, it might lose its color memory. The XmlIgnore() command should only be used for DataSeries objects that cannot be serialized.

Also proper serialization should make disappear the main plot, which is no longer needed. This is achieved via

Code

PlotsConfigurable = false;

But then you need to serialize PlotStyle, DashStyle and LineWidth separately, which I have done. Now the indicator dialogue box only shows the necessary information for the colored plot.

I have further simplified the code, and - to speed the indicator up - created an SMA object, which is initialized in OnStartUp().

Please find my fix below. Not tested for bugs.

Because it was in the first indicator I copied from when trying to learn to code and it seemed to work...

See I told ya I wasn't a professional...... and that you write cleaner code than me ... soooo , once again I am right ...

Can we use the SMAColorsV7's PlotColors as strategy trigger?

like
if (SMAColorsV7.PlotColors[0][0] == Color.Red)
EnterShort();
