Draw.Ellipse problem with 8.0.6 version

[blar58]

Has something changed with version 8.0.6 relating to Draw.Ellipse method.
Was working fine before.
I get the following error message. : On Render method Index was out of range.
Must be non-negative and less than the size of the collection.
Parameter name: index

Stack :

Hello blar58, and thank you for your report. I was unable to see quite the same thing on my end with the attached test indicator. Could you try, inside an empty workspace, running this indicator on a chart? If you are unable to make this behavior happen again, could you change the test script I sent your way so it causes the same log and output messages? Thank you for helping to improve NinjaTrader 8.

This is most likely caused by a custom skin. I ran into the same problem, which I fixed by copying the relevant .xaml files from templates\Skins\Slate Gray to my custom skin folder:
ChartControl.xaml
BasicEntry.xaml
FxPro.xaml
OrderTicket.xaml
SuperDom.xaml

If you have modified any of those in your customization, you will need to merge your code.

Many Thanks tradesmart

I was using a custom skin ...

Still working on my Draw.Ellipse problem

Thanks

I am glad tradesmart's advice resolved your second query. If you are able to run the test I suggested in post 3 this will make it easier to give the best assistance possible. If you are not please let us know so we can find a different way to help.

blar58,

In your original post (#1) in this post (Draw.Ellipse problem with 8.0.6 version), you referred to the Stack as part of your debugging. How / where do you view the stack?

Apologies, I do not wish to hijack your forum post.

Thanks
Shannon

I print the stack from the try catch.
In the catch I print the error message e.Message and the stack e.StackTrace.

Ex :

try {

}
catch( Exception e)
{
Print(" Error : "+e.Message+" Stack : "+e.StackTrace);
}

Hope it helps

I understand your time is valuable. To answer your question directly, the message you saw generated during OnRender is typically the result of a relative index reference rather than an absolute index reference. This is to say that methods that start counting with 0 as the current bar should not be used during OnRender. Methods that treat 0 as the least recent bar are safe, as are methods that take DateTime objects as arguments.

Since you are mentioning drawing ellipses, the Draw.Ellipse method has an overload which takes a DateTime as an argument. I recommend using this overload in your code. If you are already doing this and this behavior persists please let us know. You can store a DateTime that correlates to a bar during OnBarUpdate by referencing Time[0] .
