Exception while looking at chart

[heech]

Hi,

I had loaded a chart of HE 10-09, connected to IQFEED. The default instrument template seemed to be showing only the morning session (9:30 - 1 PM CST) instead of the full day session. I tried playing with the data series in the chart, by changing it to "default 24/7"... when I did this, Ninja caught an exception and crashed. Trace file shows:

I'm new to submitting errors, by the way, so if you guys want this info in some other form... just let me know!

Thanks heech, will attempt to reproduce here - correct the default instrument template would show you the regular hours only.

[NinjaTrader_Dierk]

We're actually chasing this one quite a while, but haven't been able to reproduce.

Would be really great if you could provide a step-by-step guide on how to reproduce. Either on a fresh setup or you needed to send me DB and the like...

Thanks

Dierk,

I just reproduced it with a fresh start (without being connected to Iqfeed), I'll attach the workspace which has the chart already open.

Ctrl-F to bring up the dataseries dialog.
Session Template was "Use instrument default"; change to "Default 24/7"
Click Okay.

I get an immediate error at that point.

[NinjaTrader_Dierk]

Nope, can't reproduce. Could be several reasons:
- our IQFeed account would not have data for HE
- what timezone are you in?
- I probably needed your DB as well

In case you would be fine with taking next step then:
- could you please send me your IQFeed credentials
- zipped DB
- what timezone are you in?

To "dierk AT ninjatrader DOT com". Thanks

Dirk,

I'm pacific standard time. I don't have a problem with sending you Iqfeed credentials, but I doubt you'll need them... I'm seeing the problem without connecting.

Zipped database is too large to attach.. I'll email to you. Let me know if you still can't reproduce.

>> but I doubt you'll need them
Right but needed some data (which is no longer hosted by the DB file).
