Unhandled Exception - Not Enough Quota is Available...

[RandomTask]

I'm having a problem associated with a strategy I am creating. It seems to happen after I have been enabling/disabling the strategy several times. I can recreate the problem by checking and unchecking "Enabled" repeatedly on the strategy tab until a crash. When it happens, NT8 (latest build) freezes and the following is always shown in the trace file. Is this a result of an underlying NT8 problem or something potentially in my code?

Hello RandomTask,

Thank you for the post.

The error you are getting is likely a result of some logic that you are using in your code. If you otherwise don't get this error when enabling other scripts, then it is very likely related to something in your code. You can test the same situation with the SampleMACrossOver to see if the error also happens.

If this is specifically related to your code, you should be able to further diagnose what is causing that by commenting out the logic in your script and repeating the test until it no longer happens. Once you find the combination of syntax that causes the problem, we could review that specifically if it is not apparent why.

If this happens in general with other scripts, this may be related to pc performance. You can also search for this error online to see some general windows suggestions and resolutions. This can happen if your pc has limited resources and the platform does not have enough resources left for the action being completed.

I look forward to being of further assistance.

Hello, I am getting this error now. NOT from enabling and disabling quickly. Doesn't the text of this error have some meaning? Just saying "something in your code" is a bit vague. It just started happening and I haven't changed anything. I don't know yet if I will get it again.

Hello DarkWehler,

We have a support article about this error: https://support.ninjatrader.com/s/ar...s-this-Command

You can follow the suggestions there if this error is occurring regardless of the strategy used.

As Jesse mentioned, if this is only occurring with your own script you will need to debug it to diagnose further.
