Bug in simulator - pressing REV causes exception.

[JS999]

When I try trading on sim in beta version 6, I get an exception that pops up when I try to reverse positions. It doesn't happen every time, but within a few attempts, I get a message saying that NT must shut down, and the following exception in the trace log:

2010-01-13 11:50:53:620 in OnUnhandledThreadException
2010-01-13 11:50:53:623 ********* exception trapped *********

Also, as soon as this happens, I find that the simulator immediately starts acting very "sluggish", with trades takes many seconds to "go through" after the button is clicked. Interestingly, shutting down the program doesn't solve this problem with sluggish trades, but resetting the simulator does.

This probably is related to the ATM template(s) you're using. I suggest deleting the template and settings them up again. This might make a difference.

Thanks, I'll give it a shot...

Alright, so I deleted all the ATM templates and set them up again, but I just got the error again:

It's obviously not my ATM strategies, since I recreated them as you said. The strategy I was using was a simple 7 tick stop with no other modifications. I have a feeling that this could be related to the code itself...

Please see if Tools->Options->Data->Repair DB makes any difference.

If not, then would you have a reproducible scenario preferred on sim feed? If so, then:
- please zip and attach your DB <my documents>/NinjaTrader7/db/NinjaTrader.sdf
- please provide any details needed to reproduce the issue

Thanks in advance

I did the DB repair, we'll see if that helps. Unfortunately it's not reproducible, as it does not happen every time. I will report back if I continue to see the issue...
