Custom Indicator Not 'Sticking'

[FatCanary]

Hi

Would there be a common reason why a custom indicator (or any indicator for that matter) applied to a chart would then be missing from the chart after restarting NinjaTrader?

Am I missing something obvious?

Hello FatCanary,

There could be many reasons why this occurs as the software is in Beta. However please try and re import the custom script to troubleshoot.

Hi Shawn

I was afraid of that. I was hoping I had missed something stupid.

Guess I had better go digging...

Would it be worth me exporting my indicator and then re-importing it?
Might that cure the problem?

[FatCanary]

Exporting and then re-importing hasn't worked.

Looks like a problem with my code then.

[FatCanary]

On second thoughts, how can it be my code?
I can manually load my indicator and it works fine.

I've tried custom indicators from the Version 8 Indicators forum and they all automatically load on NT startup.

Hello FatCanary,

Could you please send me your log and trace files from within NinjaTrader. Go to Control Center-->Help-->Mail to Support in NinjaTrader. Put 'Att Shawn', in the subject field and enable 'Log and trace files'. Also, give a reference of this thread in the body of the email.

Look in the log for any errors. You probably have a serialization error.

Hi koganam

Thanks for the response.

In the log I have:
Could not save indicator ':' There was an error generating the XML document.

and

Failed to restore Indicator 'Unknown'. Most likely (a) the implementation changed or (b) one or more properties have been renamed or removed or (c) the custom assembly which implements this Indicator no longer is there.

Fixed it.

I had:

#region Properties						
		[NinjaScriptProperty]		
		[Display(Name = "Border Color", Description = "Pane border color", GroupName = "Colors", Order = 0)]
		public Brush BorderBrush

There was a missing XmlIgnore.
I now have:

#region Properties						
		[XmlIgnore()]		
		[Display(Name = "Border Color", Description = "Pane border color", GroupName = "Colors", Order = 0)]
		public Brush BorderBrush

Which may be a suboptimal solution. You might want to properly serialize the brush instead.

Hi koganam

I have:

[XmlIgnore()]		
		[Display(Name = "Border Color", Description = "Panel border color", GroupName = "Colors", Order = 0)]
		public Brush BorderBrush
		{	
            get { return borderBrush; }
        	set { borderBrush = value; }
            }
				
		[Browsable(false)]
    	public string BorderBrushSerialize
    	{
        	get { return Serialize.BrushToString(borderBrush); }
            set { BorderBrush = Serialize.StringToBrush(value); }
    	}

Is that what you mean?

Absolutely. You did not show that code originally, so I did not know that you had already done it. You have really resolved the problem.

[FatCanary]

Yeah, sorry, I was just showing the erroneous part of my code.
