Error Cursor Erratic and Freezes

[JerryWar]

I have been having trouble with the cursor all day. At one Point I was able to clear the issue by switching from crosshairs to pointer and back. However when opening Ninja after hours I just happened to notice this error entry in the log on Power up referencing the crosshairs.

Error in realtime market data handling: System.NullReferenceException: Object reference not set to an instance of an object.at NinjaTrader.Gui.Chart.ChartControl.UpdateGlobalCro sshairNow(GlobalCrosshairChangedEventArgs e)at NinjaTrader.Gui.Chart.ChartControl.<>c__DisplayCla ss1fd.<OnRealtimeDataTimerTick>b__1f8()at System.Windows.Threading.Dispatcher.Invoke(Action callback, DispatcherPriority priority, CancellationToken cancellationToken, TimeSpan timeout)at System.Windows.Threading.Dispatcher.Invoke(Action callback)at NinjaTrader.Gui.Chart.ChartControl.OnRealtimeDataT imerTick(Object s, EventArgs e2)at NinjaTrader.Cbi.Instrument.<>c__DisplayClass9d.<On RealtimeDataTimerElapsed>b__9a(SubscribedThread[] threads, Int32 i, RealtimeEvents evts)

Hello,

This sounds like either some kind of corruption in NinjaTrader's core program files, or perhaps something going wrong in the Microsoft .NET Framework.

As a first step to troubleshoot this, please uninstall and reinstall NinjaTrader via the steps below (you will not lose your workspaces, templates, strategies, or other user settings in this process).

• Close all running applications.
  
• Then from the Start menu select --> Control Panel --> Add and Remove Programs.
  
• From Add and Remove Programs select NinjaTrader 7 and click Remove.
  
• Reboot your machine.
  
• Once these steps are completed, download NT7 from the link below:

Download

Please let me know if you are still seeing the same issue after the reinstall.

Don't you mean ninja trader 8? Or is this an NT7 problem in the wrong forum?

I switched to "Local" instead of Global and I do not get the log
Error on Startup.

Thank you for letting us know. I will test the global crosshair a bit further and see if I can replicate the odd behavior or the error message.
