Problem saving chart template

[asterio]

Hi there,

I notice that in some cases, NT can't save templates due a failure on Indicator class reflection. I finally found a solution, but it was giving my nuts.

I made a simple example to show the issue.

namespace NinjaTrader.NinjaScript.Indicators {

    public class [B]MyOrder[/B] {  // Simple demo class
        public double price;

        public MyOrder(double price=0) {
            this.price = price;
        }
    }

    public class MyIndicator : Indicator {

        [B]public MyOrder signal_entry; [/B] // the reflection fails when this line is uncommented

        protected override void OnStateChange() {

            switch (State) {
                case State.SetDefaults: {
                    Description = @"My Indicator base classs";
                    Name = this.GetType().Name;
                    Calculate               = Calculate.OnBarClose;
                    IsOverlay               = false;
                    DisplayInDataBox        = true;
                    DrawOnPricePanel        = false;
                    DrawHorizontalGridLines = true;
                    DrawVerticalGridLines   = true;
                    PaintPriceMarkers       = true;
                    ScaleJustification      = NinjaTrader.Gui.Chart.ScaleJustification.Right;
                    //Disable this property if your indicator requires custom values that cumulate with each new market data event.
                    //See Help Guide for additional information.
                    IsSuspendedWhileInactive = true;
                    break;
                }
                case State.Configure: {
                    AddLine(Brushes.Yellow, 0, "Zero");
                    break;
                }
            }
        }

        protected override void OnBarUpdate() {
            Print("I'm alive:" + Time[0]);
        }

        #region Properties
        #endregion
    }
}

Even more surprising is the fact that if I declare protected this member, everything works fine.

Can anyone give me a hint about that problem?, seems a design decision, not really a problem.

Hello,

Thank you for the post.

Yes, this would be expected for any complex object that you make into a public property. You would either need to make this a private property or mark this property as [XmlIgnore].

We have a sample of the syntax to ignore a property, and also make a serialization property here: https://ninjatrader.com/support/help...definedbrushes

The same concept applies to any complex object, not just a brush. The platform is trying to save this with the template which is not wanted, so you would need to ignore it or make it not publically visible.


Please let me know if I may be of further assistance.

Thank you Jesse!

I also get the point on using [XmlIgnore] .

Great!
