Cannot enable strategy v8.1.2.1

[Conceptzx]

Every time I try to enable a strategy NT8 crashes, I fought with this all day today and cannot sort it out. Doesn't matter what strategy, every one has the same problem. Here are two ends of trace files where you can see this is happening on more than just one strategy. It's doing this on any strategy I try to enable.

My code compiles, I have debug mode and show warnings enabled, no warnings are displayed right now. only the following when I try to check things in Visual Studio:

Any suggestions?

I found an older backup I made of my nt8 installation and restored it, had to build things from there. Still no idea what was causing this behavior.

Hello Conceptzx,

Thanks for posting.


This appears to occur after a data request. On the chart you're applying the strategy to, what interval and chart style is in use? Are any custom add-on's applied to this chart?

When you mention that multiple strategies were tested, did you also test the native Sample strategies included in the software in simulation, such as the SampleMACrossover strategy?

Should this same behavior occur again, I'd like to review your log and trace files for this item, which should not be posted publicly on the forum. You can send me your log and trace files by going to the Control Center-> Help-> Email Support. Please ensure 'Log and Trace Files' is checked to include these files. This is checked by default.

Please include a link to this forum thread and reference the following ticket number in the body of the email: 04246657 ATTN: Drew

The data was loaded on the chart, it occurred with both live and playback data. I did not try the sample strategies, honestly I was trying to get something work and missed a whole day of trading trying to diagnose and resolve the issue. Will make a point to save the broken configuration with log and trace files if I experience anything like that again.
