new beta11 bug?

[zweistein]

Hello ,


just installed b11 over my NT b10 and I get a new assertion error!
With respect to my indicators/strategies nothing has changed.

It says barsArray[0]==0


and in the trace:

2010-03-19 08:32:09:501 ERROR: Error on calculating indicator min/max value for indicator 'InterestZones'. Please check the 'GetMinMaxValues' method: Object reference not set to an instance of an object.
2010-03-19 08:32:10:515 ERROR: Error on calculating indicator min/max value for indicator 'EconNews'. Please check the 'GetMinMaxValues' method: Object reference not set to an instance of an object.
2010-03-19 08:32:12:075 ERROR: Error on calculating indicator min/max value for indicator 'EconNews'. Please check the 'GetMinMaxValues' method: Object reference not set to an instance of an object.

I never call GetMinManxValues from these indicators. Both , InterestZones and EconNews have worked flawlessly before and they do not anything special...

attached the error:

Could you please post one of the offending indicators so we could take a look? Thanks

There is a line of code in the EconNews script that is not compatible with NT7. You need to comment it out for it to work. See this thread for more info:

I too get the same error message. When I choose "ignore" Nt7 b11 works as normal. If I choose "retry", I get JIT error message.
Screen shots attached.

I believe this is the same issue which we have under ivestigation right now. I suggest retrying after next beta.

Same problem

I'm also experiencing this very strange error - plus when I load my indicator NT7 build11 crashes with the following error:

3/22/2010 9:21:26 PM Default Error on calculating indicator min/max value for indicator 'PaintBarHighLow'. Please check the 'GetMinMaxValues' method: Index was outside the bounds of the array.

I have included a zip of the indicator I'm working on - please take a look and let me know if it's me who's screwing up or if it's a beta problem. I already wasted three hours on this and am getting burned out as you can imagine.

Thanks for reporting. We'll take a look.

Hi molecool !

We tried to reproduce the error you reported, but weren't successful. Only think we noticed, it took very long until chart came back, before NT seemed to hang, but finally got to working again.

Can you please tell us which settings the chart has, on which you apply your indicator:
- instrument
- period (1 minute, 150 tick, else ?)
- how much data (days back)
- what session template ?

And did you also recognize the hanging of NT with the indicator you posted ?

Thanks,
Christian

Thanks for reporting. We'll take a look.

That's great - but it's a very simple indicator - any thoughts as to why this is breaking? I'm kind of stuck... thanks!

Would you mind providing info as requested by Christian below? Thanks

Alright, didn't see that response just now.

Instrument: ES ##-##
Period: 1 minute
How much: 10 days
Session template: CME US Index futures.

And yes, I definitely noticed it hanging for at least 20 seconds - and I have a kick ass 4-core 64bit Win7 system with 6GB of RAM. I'm running complex other strategies in NT7 just fine during the day (400 lines of code +) and they run without problems (to my surprise).

But this little indicator is kicking my butt - not sure why it's breaking. May be an NT7 thing - I have not tried it in 6.5.

Your help is appreciated.

Boy, you are fast - LOL :-)

I just did - sorry, was working my way up.

Hi molecool !

- from which provider is your data ?
- are you connected when this happens ? does it also happen when you are disconnected ?
- does this also happen with 10 days back on ES 06-10 ?
- does it change anything when you apply the indicator on a chart with 100 bars back, instead of 10 days ?
- you really do only open the chart, then add the indicator and then it crashes ? No historical reload, restore or pressing F5 ?

In addition pls. execute the steps which it takes and do not execute the last (do not crash), then close NT, saving your workspace. Open NT again -> Help -> Mail to support. Make sure 'Workspace files and UI settings' and 'Template files' is checked and you add 'for Christian' in the subject.

Thanks,
Christian

- from which provider is your data ? DTN
- are you connected when this happens ? does it also happen when you are disconnected ? yes
- does this also happen with 10 days back on ES 06-10 ? yes
- does it change anything when you apply the indicator on a chart with 100 bars back, instead of 10 days ? no
- you really do only open the chart, then add the indicator and then it crashes ? No historical reload, restore or pressing F5 ? yes - in both cases

Not sure what you're asking me to do there though. This should be a simple fix if it can be replicated on your end.

Hi molecool !

Could still not reproduce. We are unable to fix, when we can't reproduce. Ok, let's do the following:
- pls. take a screenshot of your chart, just before you add the indicator, which then would make the indicator crash
- pls. right click on middle of chart -> chart properties, and take a screenshot
- right click in y axis area, properties, take a screenshot
- open indicator dialog, make sure all indicator properties are visible, and take a screenshot

Pls. send all screenshots to christian AT ninjatrader DOT com

Thanks,
Christian
