CLV (Accum/Dist) study error

[dave]

I am attempting to add a CLV study to my charts. I think I have things set correctly, but the chart control stops with an Overflow error. I have a basic CandleChart in my sample program (attached). This one does not have a volume series, but I have set CLVFunction.Volume = Nothing. In my main program where I found this error, I do have a volume series which is populated with data. In that one, setting the .Volume property has no effect on the error. A partial listing of the error stack trace is shown below. The sample program, with data is attached.

If you can show me where I am setting something incorrectly, I would appreciate it.

Hello dave,

Sorry for the delay. I have reproduce your problem using last version of TeeChart.Net and I have added your request in bug list report with number [TF02015348]. We try to fix it for next maintenance releases of TeeChart.Net.

Thanks,

Hi Dave,

We have been investigating the issue further and we found that it's not a bug. The solution is setting the TreatNaNAsNull property to true as shown here:

Code: Select all

                line1.TreatNulls = Steema.TeeChart.Styles.TreatNullsStyle.DoNotPaint
                line1.TreatNaNAsNull = True '<-New Line
                line1.CheckDataSource()
                line1.Tag = Func1Tag

Can you please check if this works fine at your end?

Thanks in advance.

Sorry for not responding sooner. I had stopped following this thread once it was designated as a problem in the control.

I tried your solution and it did work for me. Thank you very much.

As far as I know, there is still an issue with the Commodity Channel Indicator study. It was going to be addressed in the next maintenance release. Do you have any estimates on when the next update might be released?

Hello Dave,

As far as I know, there is still an issue with the Commodity Channel Indicator study. It was going to be addressed in the next maintenance release. Do you have any estimates on when the next update might be released?

I can't still provide an estimate date so the last maintenance release appears this week (09 Feb). I recommend you to be aware at this forum, our RSS news feed, twitter and facebook accounts for new release announcements and what's implemented on them.

On the other hand, I have increase severity of bugs (TF02015363) and feature request (TF02015361) so to be reviewed for future versions.

Thanks,
