NT8 Crash on modify of OCO order as match is filled.

[crokusek]

Hi,

A limit buy was filled at "exactly" the same time I decremented a matching OCO stop order using the decrement key in the control panel orders tab. I can send log files if needed.

Thanks,
Chris

The trace file did capture it:

Hello,

Thank you for posting.

So that I may investigate I would ask that you contact me by email at PlatformSupport [AT] NinjaTrader [DOT] com. In your message please include a link to this forum thread and a copy of today's log and trace files. You will find these diagnostic file in the Documents > NinjaTrader 8 > Trace folder. I will need to review a copy of the files which are named 'log.20170222.XXXXX.txt' and 'trace.20170222.XXXXX.txt'. There will likely be multiple files for each day.

I just sent the log and trace files.
