Log Error with JurbolBBmacd indicator

[Taddypole]

I've installed the JurbolBBmacd indicator found in the NT8 indicators.

When I launch NT8 and have a chart with this indicator loaded I get an error in the Log file.

Error on calling 'OnStateChange' method: Added Plots or Lines must have a unique name

Any idea what is causing this?

I got it also.

They sure look unique. Connecting to Playback-MR shows no issues.

			else if (State == State.Configure)
			{
				AddPlot(new Stroke(Brushes.Orange, 4), PlotStyle.Dot, "Macd");
				AddPlot(new Stroke(Brushes.Black, 1), PlotStyle.Line, "Avg");
				AddPlot(new Stroke(Brushes.LimeGreen, 2), PlotStyle.Line, "BUpper");
				AddPlot(new Stroke(Brushes.Red, 2), PlotStyle.Line, "BLower");
				
				AddLine(Brushes.DarkGray, 0, "Zero line");
			}

Now my whole NT is screwed up. I tried to edit the indicator and now I get these uncorrectable errors.

I restarted and that funky error went away.

Anyways - I kept modifying the code...

Removing Brushes, going to very unique names, and it was still there.

Finally Moved it to State.SetDefaults and it stopped displaying the error message.

	
		protected override void OnStateChange()
		{
			if (State == State.SetDefaults)
			{
				Description					= @"Jurbol BBMacd. Combination of Bollinger Bands and Macd. Programmed for NT 8.";
				Name						= "JurbolBBmacd";
				Calculate					= Calculate.OnEachTick;
				IsOverlay					= false;
				DisplayInDataBox			= false;
				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(Brushes.Orange, "Macd11");
				AddPlot(Brushes.Black, "Avg11");
				AddPlot(Brushes.LimeGreen, "BUpper11");
				AddPlot(Brushes.Red, "BLower11");
				
				AddLine(Brushes.DarkGray, 0, "Zero line11");	
			}
			else if (State == State.Configure)
			{
;
			}
		}

Moving it back to State.Configure and adding a Print statement shows it is called only once.

			else if (State == State.Configure)
			{
				Print ("Jurbo State.Configure");
;AddPlot(Brushes.Orange, "Macd11");
				AddPlot(Brushes.Black, "Avg11");
				AddPlot(Brushes.LimeGreen, "BUpper11");
				AddPlot(Brushes.Red, "BLower11");
				
				AddLine(Brushes.DarkGray, 0, "Zero line11");	
			}

Output:

Jurbo State.Configure
Indicator 'JurbolBBmacd': Error on calling 'OnStateChange' method: Added Plots or Lines must have a unique name

I suspect State.Configure isn't too swift and doesn't realize it's already out there on a chart.

Strange Parameters in JurbolBBmacd indicator

Also in the JurbolBBmacd indicator are some strange parameters listed as shown in the attachment. Don't know where these are coming from.

Never seen this anomaly before.

Hello,

I just wanted to confirm the message 'Error on calling 'OnStateChange' method: Added Plots or Lines must have a unique name' would come from putting the AddPlots in Configure rather than SetDefaults. Although they are unique the message is shown when used in that state. The correct state per the help guide is SetDefaults.

For the image with the strange paramaters,

these are the properties being shown in the label, the colors specifically.

If you wanted to remove the labels and just have the name, the following code could be added into the indicators class.

public override string DisplayName
{
	get { return Name; }
}

I look forward to being of further assistance.

Warning: This method should ONLY be called within the OnStateChange() method during State.SetDefaults or State.Configure

Jesse,

How do I selectively add a ZERO line to a panel when certain options are selected? Is there a way to add a Transparent ZERO line and then change the color in the CONFIG section? In the SetDefaults, the user hasn't made up there mind yet as to the type of chart they want to see, so setting a zero line there is too early in the State sequence for AddLine().

[NJA_MC]

Okay,

Answered my own question. This worked:

1) Set transparent Line in SetDefaults
2) In Configuration, activate the line:
Lines[0].Brush=m_Black.Brush;
