Serializing Indicator

[magnumdbl]

That WORKED and now it saves in Templates.

The following code is not plotting dots as I would like.
It is supposed to plot a dot when the FATL line crosses above the SATL line.
FATL and SATL are DataSeries from added Plots in the Initialize section.

Add(new Plot(Color.Gray, PlotStyle.Line, "FATL")); Values[0] plots the line
Add(new Plot(Color.Gray, PlotStyle.Line, "SATL")); Values[2]
Add(new Plot(Color.Gray, PlotStyle.Dot, "FATLDots"));Values[4] plots dots on the line
FATL and FATLDots are SET to the same values.

if (CrossAbove(FATL,SATL,1)== true)
{
Plots[4].Pen.Color = crossUpColor;
Plots[4].Pen.Width = fatColorWidth;
} else Plots[4].Pen.Color = Color.Transparent;

Print(Time[0].ToString()+" FATL="+ FATL[0]+" SATL="+SATL);
Print(Time[0].ToString()+" If FAT Xover SAT, bool="+CrossAbove(FATL,SATL,1));

The Print statements verify that the 'if' statement is giving correct T and F readings,
However, when the code is as shown above, NO dots print (ie thay are all transparent).

If I "// out" the else statement with
} // else Plots[4].Pen.Color = Color.Transparent;

then dots appear on EVERY bar.

I must be missing something . Is there an easy fix?

magnumdbl, for changing plot colors dynamically, please use NT7's PlotColors method in your code -

Thanks,
I rewrote it using
PlotColors[4][0] = Color.FromArgb(defaultColorOpacity,crossUpColor);

because I serialized my colors.

Since I borrowed that piece of code, I'm not sure if I have to put in Opacity for a
Serialized color or if that was just something that the other developer needed.
Can anyone tell me?

[NinjaTrader_Bertrand]

Believe you would need that here, as the opacity is a component of the from ARGB derived color you create for your script.

The most common property to serialize is user defined color inputs. Details on serializing color inputs are here:

If you can share the properties region of your code we can tell if it's a different property causing this.

I'm getting "Indicator could not be serialized", and there are user defined colors in the indicator. I would love to view the thread linked above! Alas, the link appears to be broken. Please advise.

Thanks!

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

Thanks! I went through that thread and did what it said, but I'm still getting the error. I'm attaching the code. Any ideas what I'm doing wrong? Thanks again!

Style, do you have the [XmlIgnore()] for your Color properties added as well, to signify you do custom serialization for those?

I also believe your public struct will need custom serialization...

I believe I'm now using [XmlIgnore()] correctly, yet the issue remains. See the attached code.

Thanks for your help!

[NinjaTrader_Bertrand]

Yes Style, the coloring inputs should be fine, this is not what breaks it I think - the problem area is the public struct I feel, something we could also not support in our wrapper generation in NinjaScript. If you recode this area to use an enum instead you should be fine.

Not to contradict Bertrand, but your struct, while declared public, is not a Property of the class, so is unlikely to be causing a problem with the NT wrappers. I use structs pretty liberally myself, declared either as public or protected and have no issue there, unless I try to use the struct as a property, which causes a different issue actually.

It seems that the problem may be in your declaration of your DataSeries as public. If you want to access DataSeries outside of the class, you should define the access using a Property referring to a private backing store, not declare the DataSeries as public access in the code.

Thanks koganam, I missed those public DataSeries without an associated property...that's it.

That did the trick. Thanks!
