ninjatrader crashing

[junkone]

My ninjatrader kept crashing in both simulated replay and bar replay. when I looked at the log I can see the weirdest errors. what can I do to prevent it?
I am running 8.0.0.11 64-bit (Standard) - BETA

I think this has got to do with the fact that I am using the following code to check what kind of market connection that I have. how do I find out the market connection provider type
Cbi.Connection.PlaybackConnection.Status.ToString( ) == "Connected"

[junkone]

I need to know how to fix this

• Cbi.Connection.PlaybackConnection.Status.ToString( ) == "Connected"
• Is there a AppDomain.CurrentDomain.UnhandledException configured so atleast I can see the stack trace of the unhandled exceptions from Ninjatrader and try to see if my code has anything to do with it?

and NT8 still continues to crash without anything logged in the log or the trace files

In addition, I had another crash and can see the following lines in the trace log
2016-05-30 01:04:06:118 (ib-paper) Cbi.Account.AccountItemCallback: account='DU2780' accountItem=NetLiquidationByCurrency currency=UsDollar value=*****

Hello junkone,

Thank you for your post.

Can you provide the line of code you refer to with "Cbi.Connection.PlaybackConnection.Status.ToString ( ) == "Connected""? Are you trying to force a connection?

Are you running NinjaTrader 8 beta 11? Are you doing any custom rendering in the strategy or calling any objects that have custom rendering? Are you using a custom chart style?

I am running 8.0.0.11 64-bit (Standard) - BETA

1. I call a indicator from my strategy that does a drawtext

1. I have commented the lines out and am still getting the crashes. yet here it is
   // longtrade.account = Cbi.Connection.PlaybackConnection.Status.ToString( ) == "Connected" ? "replay" : "" + "indicatorbased";
   I have it in another spot
   private DateTime getTime()
   {
   return DateTime.Now;
   // return Cbi.Connection.PlaybackConnection.Status.ToString( ) == "Connected" ? Cbi.Connection.PlaybackConnection.Now : DateTime.Now;
   
   
   }

Hello junkone,

Thank you for your response.

1. What all is performed with Draw.Text or are you using graphics.DrawString?
2. You could use the following instead: Cbi.Connection.PlaybackConnection != null
