NT8 b6 locks up

[andrew56]

This problem just started late yesterday....and (unfortunately) I can replicate it at will.

Control panel opens fine...I can edit indicators or change options or do just about anything until I open a chart and try to add an indicator. The chart opens...everything looks good...but when I click on 'Indicator" and try to add one...(doesn't matter which indicator) NT8 locks up and sits there until Windows tells me it is "Not Responding".

I removed NT8....down to bare metal...and did a complete re-install of NT8 b6 from scratch...(including the import of NT7 data) all over again....Same results.

I have no idea what the heck suddenly happened.

They will need to know which market data feed connection you are using.

And they will also probably ask for your log and trace files:

...My Documents\NinjaTrader 8\log
...My Documents\NinjaTrader 8\trace

I did that early this morning.....(before I saw this post, so their is no "Attention to"...but I did include comments about the "lock up" and referred to this NT forum post.

The data feed is NinjaBroker Continuum...

Unfortunately I was unable to locate the files. Have you received a reply from another support member? If you have not can you please forward the files once again with Attn Chris Jameson in the Subject line and a link to this thread in the body of the message.

Will do....I recreated the problem this morning....sending now

I have already sent the log and trace files ... (used the NT8 Email function)....
....is that not working reliably in NT8 either???).... if not I can manually get the files and send them.

[andrew56]

OK here is log and trace files....(I just had it crash again)

[NinjaTrader_ChristopherJ]

When reviewing your files I do not see any errors listed. So I may attempt to replicate this on my end please go to Help->Email Support and be sure to include Attn: Chris Jameson in the Subject line, a link to this thread in the body and a check in the box in the following items:

• Workspace files and UI settings
• Template files
• Database file

I may have isolated the problem.....although I have no idea why it might be the problem.

I have a piece of "scratch pad code".....bits and pieces of code quickly copied and pasted into one 'temporary indicator'. I never actually call this code, nor have I ever added it to a chart.....(it gives me a Ninja Editor 'scratch pad' to cut and paste bits).
This code compiles...even though it wouldn't really do much of anything.

When this indicator is in NT8....(not called not added to a chart).....NT8 locks up when I try to add any indicator to a chart. When I remove the indicator.....NT8 starts working.

Seq of events....
- I open a NT8 chart....click on "Indicator" to add an indicator....anything HMA, EMA doesn't matter....NT locks up and crashes.

- I remove the offending code....repeat the above process....NT8 works.

Now I admit this piece of code is not functional....and Lord knows I have coded some crap in my day....but nothing I do in simple NT8 NinjaScript...(that compiles)....should cause a problem when it isn't even being loaded or called.

This could be a coincidence and the problem is elsewhere, but it seems suspicious that I can replicate this pretty much at will.

[Tiixo]

OnStateChange() with State.SetDefaults and State.Terminated is being called when you open the indicator list so that the list can have the proper default values for an indicator. Might have a look there.

[andrew56]

Thanks Tiixo !!
Other than trying to remember and 'undo' what happened when NT8 freaked out....(so I could finish my coding schedule).....I haven't taken any time to do much debugging.

Interesting observation....I may take a look at that later

The only way an indicator would be causing problems for you if it is not loaded or configured on a chart is if there is logic in the indicator's constructor, or OnStateChange(), specifically during State.SetDefaults and State.Terminated as the previous poster pointed out.

If you can share your script, I'd be happy to look into what may be causing issues with the rest of the system.
