NT8061-Playback M.R.- unhandled exception trapped

[sledge]

I have run this strategy on my laptops without much issue other than some trades not happening randomly that I can't prove out. http://ninjatrader.com/support/forum...light=playback

I had originally run the 2 variations of the strategy on 8.0.4.0 and saved off the results. I upgraded to 8.0.6.1 today, and I am running the same 2 strategies from 1/20/2014 to 5/19/2017 on my desktop.

It was definitely random...unless running 2 strategies at the same time could cause this.
Using multiple contracts...

Definitely something still a miss inside the NT code for the strategies grid.

Hello sledge,

Thank you for your report.

Would you be willing to provide the two strategies so we may test this on our end?

If so, you can send the files to platformsupport[at]ninjatrader[dot]com with 'ATTN: Patrick H' in the subject line and a reference to this thread in the body of the email.

You can export your strategies by going to Tools > Export > NinjaScript Add On > Add > select your strategies > OK > Export > name the file 'NTsupport' > Save.

The file will be located under Documents\NinjaTrader 8\bin\Custom\ExportNinjaScript. Please attach the file to your email.

I look forward to your response.

I can't.

If I come up with something I can,of course I will.

But it's nothing I'm calling. It's that strategy grid code update fails when a trade is completed.

Got it in NT8.0.11.1, this time on my laptop as opposed to the desktop. I did run with "NVidia graphics" which was updated to latest prior to the run. Another test on another laptop in NT8.0.11.0 with NVidia graphics turned on did not produce this result. Results were identical on the 2 tests. Different version of code from previous, but identical in the 2 tests.
