Unable to generate Alert Log entry since the provided brush used was unfrozen

[Wick Wrangler]

Getting this error from an entry-only strategy I created that hands off an ATM order.

Had been working fine, but getting this error today.

My alert code was taken from your ATM sample code:

 NinjaTrader.NinjaScript.Alert.AlertCallback(NinjaTrader.Cbi.Instrument.GetInstrument("MES 09-20"),
this, "LongEntryAlert", NinjaTrader.Core.Globals.Now, Priority.High, msg,
NinjaTrader.Core.Globals.InstallDir + @"\sounds\Alert1.wav",
new SolidColorBrush(Colors.Blue), new SolidColorBrush(Colors.White), 0);

How do I resolve?

Hello Wick Wrangler,

This is because you are creating new SolidColorBrush's rather than using the static brush. You can just use Brushes.Blue and Brushes.White here.

I see that this is in the help guide sample so I will forward that to be updated.

NinjaTrader.NinjaScript.Alert.AlertCallback(NinjaTrader.Cbi.Instrument.GetInstrument("MSFT"), this, "someId", NinjaTrader.Core.Globals.Now, Priority.High, "message", NinjaTrader.Core.Globals.InstallDir+@"\sounds\Alert1.wav", Brushes.Blue, Brushes.White, 0);

I look forward to being of further assistance.

Great, thanks.
