ERROR: Failed to call method 'Initialize' for indicator

[NinjaCustomer]

What does this mean? YRecent is an indicator I developed myself, but I'm currently not using it on any charts... but this always shows up in my logs:

2009-12-06 16:42:50:421 ERROR: Failed to call method 'Initialize' for indicator 'YRecent': Object reference not set to an instance of an object.
2009-12-06 16:44:33:296 ERROR: Failed to call method 'Initialize' for indicator 'YRecent': Object reference not set to an instance of an object.

2009-12-06 17:23:08:718 ERROR: Failed to call method 'Initialize' for indicator 'YRecent': Object reference not set to an instance of an object.

How do I fix it?

NinjaCustomer, expected - since the Initialize() is called each time across studies, you could comment out the part giving you the issue or debug the script -

just so you know, my indicator works fine and compiles fine...

it is just that i get this error message in the log...

could this be the culprit? I have this code in Initialize:

new DataSeries(this);

[NinjaTrader_Bertrand]

Yes, as this alone is not a fully assigned DataSeries object - http://www.ninjatrader-support.com/H...iesObject.html

[NinjaCustomer]

so what should I do?

I see no difference between my code and what you have in the Help documentation link you gave me, so do I just ignore this error message? it is harmless?

[NinjaCustomer]

btw. that was just a code fragment, of course I assigned it to a variable

[NinjaTrader_Bertrand]

You want to assign to a data series variable created in the variables section of your code -

 
protected override void Initialize() 
{ 
    myDataSeries = new DataSeries(this); 
}

[NinjaTrader_Bertrand]

Please post your full Initialize() then, thanks.

[NinjaCustomer]

just remember when reading the code, that everything works as I intended in the indicator... it is only those log error messages that make me concerned that i am writing sloppy code... i just want to rule out that my indicator could cause any instability (because of those error messages):

        protected override void Initialize()
        {
            
			lastHighCache = new ArrayList();
			lastLowCache = new ArrayList();

			swingHighSeries	= new DataSeries(this);
			swingHighSwings	= new DataSeries(this);
			swingLowSeries	= new DataSeries(this);
			swingLowSwings	= new DataSeries(this);

			prevSwingRange = -1;
			
			BarsRequired = 100;
			
			AutoScale           = false;
			DisplayInDataBox	= false;
            CalculateOnBarClose	= true;
			PaintPriceMarkers	= false;
            Overlay				= true;
			
			ActiveMarketLogFile = Environment.GetFolderPath(Environment.SpecialFolder.Personal) +
	                                    @"\misc\" + Instrument.MasterInstrument.Name + "_active_market_alerts.csv";
			
			if (logActiveMarketAlerts) File.Delete(ActiveMarketLogFile);
        }

[NinjaTrader_Bertrand]

Please move the log file calls accessing the Instrument to the first OnBarUpdate() bar and then retry.

[NinjaCustomer]

so I should just put it in a

if (CurrentBar == 0) {

}

in OnBarUpdate ?

[NinjaTrader_Bertrand]

Yes, as the Instrument would likely be emtpy (null) if not placed there...
