Indicator does not plot once NT is restarted

[Balage0922]

Hello,
the code below is a cumulative tick indicator. I experience 2 issues with it. 1: I can't drag and drop it to another panel, 2: it doesn't load to the chart after I restart Ninjatrader. I can't find any suspicious errors within the code, what can cause these errors?

namespace NinjaTrader.NinjaScript.Indicators.BaluCustom
{
public class CumulativeTick : Indicator
{

private Brush positiveBrush;
private Brush negativeBrush;


protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "CumulativeTick";
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;


AddPlot(new Stroke(Brushes.Transparent, 2), PlotStyle.Bar, "CTick");
PositiveBrush = Brushes.GreenYellow; // Default positive color
NegativeBrush = Brushes.Tomato; // Default negative color

}
else if (State == State.Configure)
{
AddDataSeries("^TICK", Data.BarsPeriodType.Tick, 1, Data.MarketDataType.Last);
}

else if (State == State.DataLoaded)
{
CTick = new Series<double>(this, MaximumBarsLookBack.Infinite);
}
}

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 10 ||CurrentBars[1] < 10 )
return;

// Logic
CTick[0] = (Closes[1][0] + (CTick[1])) ;

Values[0][0]=CTick[0];

// Set color based on CTick value
PlotBrushes[0][0] = CTick[0] >= 0 ? positiveBrush : negativeBrush;

// Reset EOD
if (Bars.IsLastBarOfSession == true)
{
CTick[0] = 0;
}
}

[XmlIgnore] // Prevents the CTick plot from being serialized
public Series<double> CTick { get; private set; }

Hello Balage0922,

Thank you for your post.

If the indicator isn't saving to the workspace, it is likely because some of your properties haven't been properly serialized, such as your Brush inputs.

Below is a Help Guide page which includes sample code on serializing brushes.

https://ninjatrader.com/support/helpguides/nt8/user_definable_color_inputs.htm

As far as dragging and dropping the indicator, try testing again after properly serializing all the inputs in the script.
