[pjsmith]

Hi,

I have an indicator - It has no configuration vaiables. NT always removes it from my chart on start up.

In the log I have this

2017-02-10 14:36:15:100 ERROR: Could not save indicator 'pjsLights:' There was an error generating the XML document.
2017-02-10 14:37:26:134 ERROR: Could not save indicator 'pjsLights:' There was an error generating the XML document.

My whole properties section is this (which I belive saves nothing?)

#region Properties

[Browsable(false)]
[XmlIgnore]
public Series<double> SCORE
{
get { return Values[0]; }
}

[Browsable(false)]
[XmlIgnore]
public Series<double> ADD
{
get { return Values[1]; }
}

[Browsable(false)]
[XmlIgnore]
public Series<double> DELTA
{
get { return Values[2]; }
}

[Browsable(false)]
[XmlIgnore]
public Series<double> TICK
{
get { return Values[3]; }
}

[Browsable(false)]
[XmlIgnore]
public Series<double> TREND
{
get { return Values[4]; }
}


#endregion



What am I missing? This is with the latest NT8, though has I think been an issue for some time.

Thanks.

Hello pjsmith,

Thank you for your note.

Without the full code we're unable to test on our end.

If you'd like to upload the full code I can take a look and see if anything jumps out. Or if you'd prefer to email a copy, send to platformsupport[at]ninjatrader[dot]com with Attn: Alan P in the Subject line. Also within the email please include a link to this thread, and the files.

I look forward to your reply.

Hello,

I belive I may have found the reason for this, and I think it may be an NT bug. I am not sure how to resolve, however.

You appear to be able to cause this issue, which prevents your indicators being saved to your charts if you update an indicator that has been previously used so it no longer has one of it's plots.

For instance, this indicator had 5 plots. I removed one as it is no longer used. Depsite the indicator unctioning normally and the correct plots showing, the indicator will not stay on a chart as NT reports an XML error when trying to save the setup. What I noticed is despite the indicator working and certainly having been updated, plot no longer in the code, the plot is still in the indicator properties. Somehow, NT appears to be recalling the plot that no longer exists and trying to save it, but of course failing as it no longer in the indicator.

Just a theory, but is an issue no the less. That plot should not be in the indicator properties as it is certainly no longer in the code. I am unsure how NT handles the indicator properties/variables.

If you can enlighten me how to manually remove this from NT, or reset it, I can test and confirm this is the issue causing the XML errors.

Hope this makes sense.

Thanks.

Hello pjsmith,

I am unable to replicate.

Are you removing all references to the plot within the code? Are you refreshing the chart after the modifications?

I provided a screen shot of an indicators code I applied to a chart, commented out the references to the third plot, then saved the workspace with no problem.

I look forward to your reply.
