IEnumerable not compiling

[TheBean236]

I'm trying to create anchors (first time). I used the helpGuide example as a basic template, but when I compile, I get "... no suitable method found to override" on the line public override IEnumerable<ChartAnchor> Anchors. The helpGuide clearly states that "override" is required. When I remove "override", it compiles fine.

Do I really need it "override" directive or and I doing something else wrong?.

Thanks for your help.

Hello TheBean236,

The override you are trying to use is for a DrawingTool but it looks like you are using an indicator which would not have that override.

Are you trying to make a collection of anchors that your indicator can use to store other anchors? What is your end goal?

The override specifically would only be used for a drawing object and is how it stores its anchor collection.

I look forward to being of further assistance.

I understand. Thanks. I tried it under DrawingTools and it compiles fine.
I'll do my initial development there.

Thanks again,
Michael
