I can not reproduce here.

1) What release are you running on?
2) Please
- terminate NT
- remove <install>\bin\Custom\NinjaTrader.Custom.d ll
- start NT
- pull up any custom or system indicator file
- right click -> compile
- try again typign in "NinjaTrader."

That fixed it - thanks.

After I posted that I discovered that it was happening will all packages and not just the NinjaTrader package so must have been something to do with the first time that I ran that version of Ninja.

I'm running the most recent version that could be downloaded as of yesterday (3/17).

Thanks. So it was 5.1.1000.1.

What version had you installed before?

Yes 5.1.1000.1

Previously installed was one of the betas that included Ninja Script - I can't remember which one.

Exception caused by ActiproSoftware

For both NT 6.5.1000.14 and NT 7.0.0.5

When you open an indicator with the NT editor and then quickly turn the mouse wheel to scroll down the code of an indicator, this may cause an exception. (This happens before any modification of the code, just looking at the indicator). I have observed this problem regularly for all versions of NT 6.5. and also NT 7. Restart of NT solves the issue, next time I turn the mouse wheel slowly.....

Please find below excerpt from the trace file of today relating to the exception:

Did not post it for NT 7, because it is a minor bug, but maybe you could check with ActiproSoftware the reasons for this.

[NinjaTrader_Dierk]

Sorry, I could not reproduce on latest NT7B5. I started scrolling mouse wheel right after double clicking on the indicator file in the indicator dialog. Works no problem here.

[Harry]

Thankyou for answering, Dierk. This does not happen every time, but it only causes exceptions from time to time.

I just tried 5 times and could not reprocude it either. But I know it will happen again.

FYI.
My NT editor has caused a crash in NT twice during the las few days.
NT version: 8.0.19.1 64-bit .

Today with the error message:
Unhandled exception: Unable to cast object of type ActiproSoftware.Text.Languages.DotNet.Ast.Implemen tation.QualifiedName to type ActiproSoftware.Text.Languages.DotNet.Ast.Implemen tation.Expression.

The day before yesterday with the error message:
Unhandled exception: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Unhandled exception: Exception has been thrown by the target of an invocation.

Hello poseidon_sthlm,

We can only investigate issues seen with the current version of the platform.

Please update to the latest version from the link below, and then please set up only what is necessary to reproduce the exception.

https://ninjatrader.com/PlatformDirect

As this thread is for NinjaTrader 7 and is extremely old, please open a new thread in the NinjaTrader8 forums including a screenshot that shows what is necessary to reproduce the exception in the Strategy Builder. If you have encountered this exception with the NinjaScript Editor, please include copy of the source code file that has only what is necessary to encounter the exception.

NinjaScript source code is included in the Documents\NinjaTrader 8\bin\Custom\ folder. You may look in the Indicators or Strategies folder to find the CS file for the script in question and then add it to a zip file to share on the forums.

If you need further direction on how to open a new thread, please see the Forum FAQ - https://ninjatrader.com/support/forum/help

We look forward to assisting.
