NT crashed & won't restart

[safetrading]

I'm a licensed user of NT. While running it this morning, it crashed. When I tried to restart it I get the splash screen with the message on it, "Restoring workspace 'Default' ", the DOM and control panel opens, and the window border of one chart ( I had 3 before the crash). After about five minutes, I get the message, "NT needs to close".

I have restarted my computer and NT 3 times with no success. Please help.

Hello Safetrading,

Thank you for your post.

Can you please remove your workspaces. To remove your workspaces:

• Please close NinjaTrader and go to your desktop Start menu
• Open My Documents
• Go to the NinjaTrader 6.5 folder
• Go to the Workspaces folder
• Right click on all XML documents and select Cut
• Place the cut files in an easily accessible location
• Now restart the application and it should start up normally

That got NT to open again. Once I added my indicators again, it crashed again. This morning I edited one of my indicators by adding the following;

Added to the protected overide void Initialize()

Add(new Plot(Color.FromKnownColor(KnownColor.Transparent), PlotStyle.Line, "PercentB"));

Added to the protected override void OnBarUpdate()

double PB = BollingerSMA313(1).Plot0[0] / (BollingerSMA313(1).UpperBand[0] - BollingerSMA313(1).LowerBand[0]);

PercentB.Set(PB);

Added to the #region Properties

[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries PercentB
{
get { return Values[3]; }
}

When I remove the lines in the protected overide void OnBarUpdate() section, NT works. When I add them back again, it crashes. Is there a way to overcome this?

safetrading,

Please add a check to ensure that you are not doing a division by zero and then try again. You will need to ensure the difference between the two values you are subtracting is greater than double.Epsilon as discussed in this tip: http://www.ninjatrader-support2.com/...ead.php?t=3929
