Complete Freeze of NinjaTrader

[Harry]

This is by far the biggest problem with NinjaTrader. I am an experienced long term user of the product, and still I cannot tame it. Today it crashed and is completely dysfunctional.

This is the problem:

With any workspace and any chart (old workspace, new workspace, default chart, complex chart), if I right click on a chart and select "Indicator", it is the end. Same if I select Ctrl-I, so it is not mouse related. See screenshot below.

NinjaTrader simply stops working and is frozen. No CPU load, moderate RAM usage (160 k). Completely dead.

After restart of NT I made a number of tests:

-> checked assemblies: no assembly installed
-> edited an indicator and compiled: no problems, anyhow same indicators as yesterday
-> checked trace file -> no messages
-> checked log file -> no messages
-> checked other options from drop down menu -> no problems

These are the really frightening NT experiences. It simply stops working for no reason. Only way out is to kill the NinjaTrader.exe process.

I am fortunate that this happened on a week-end, so I will now try to find the error. First thing I did, was a complete reinstall of NinjaTrader 7.1000.3, but the bug persists.

NinjaTrader will still freeze, when I try to open the indicator dialogue box. So I will now explore the files in the directory My Documents -> NinjaTrader 7

Me 2 absolute total freeze up. Where to start to look? Or should I just delete 7.3beta and reinstall earlier version? this is ridiculous

I am further exploring.

I have now replaced the files under NinjaTrader 7 -> bin -> Custom one by one, and I have found the culprit. The culprit is the file NinjaTrader.Custom.dll. If I replace the file of my NinjaTrader installation with the original file, then the problem will not occur. The original file which is installed when downloading NT 7.0.1000.3 has a size of 344 KB, my file had the size of 4.492 KB, as I had added some indicators.

So I replaced my NinjaTrader.Custom.dll with the original file. Then I added all my indicators and the problem occured again. So we have the paradox situation that

-> compiling all my indicators works out correctly (no error message)
-> after compiling the indicator dialogue box cannot be opened anymore

Interesting enough the same set of indicators did not produce any problem yesterday.

I will now add the indicators one by one to check, whether the problem can be tracked down to a specific indicator, or whether NinjaTrader cannot compile more than 250 indicators at once. I am now at 250 indicators, and what I notice is that NinjaTrader hangs a short moment, when I open the indicator dialogue box.

After further testing I could track the problem down to the jtEcoNews indicator. I have installed this indicator since weeks, but today when I use it with NT 7.0.1000.3 it produces the problem. There were no problems however during the last week with NT 7.0.0.1000.3 , and I am 100% sure that this indicator was part of my NinjaTrader install.

So this is the intermediate result:

NinjaTrader 7.0.1000.3 + jtEcoNews + WeekEnd -> NinjaTrader freezes.

The strange thing is that this indicator compiles without problems, but once it is installed it prevents the indicator dialogue box from popping up.

This is reproducible and was also tested by adding this indicator to the default system indicators without interference of other custom indicators.

Hi Harry,

Thank you for your post and for the clarification of the issue, and so far I am unable to duplicate the issue. The JtEconNews indicator available from the forum that I imported did not produce the issue either, and to further test I am curious if you could provide the file you identified to see if I can duplicate what you have found.
