This document makes reference to building your own chart styles:

But I get a compiler error when to added this:

Do I need a reference to Fidelity.Components?

If so where do I get this from?

Have you noticed what exactly "a compiler error" is telling?

You can save some time by playing with the fully functional Community ChartStyles library (make sure you're logged in to the Wiki to see attachments):

* Home - Community ChartStyles > Download "Community ChartStyles" project source

(However, if you decide to use this as the basis for your own project you should rename the assembly so as not to conflict with the extension of the same name.)

no suitable method found to override

I must be missing the assembly reference to Fidelity.Components?

No, it's not necessary for RenderBars as you imply. But it is required if you implement ICustomSettings (ReadSettings, WriteSettings).

Can I please download this component.

It's in Wealth-Lab's installation folder (Fidelity.Components.dll).

I only see this one: WealthLab.Components.Community.dll

Ok I see it. So why the compiler error when I add this?

Sounds like you overlooked to reference WealthLab.dll.

What are all those indicator libraries and the "pushed indicator" statement are doing there? Don't tell me that you're trying to build the library in a Wealth-Lab Strategy. ;) As per the API manual (page 1), you need Visual Studio.

Also let me again suggest that you revisit my post #2 and proceed as suggested there to save you learning curve which seems somewhat steep.

I was ;(

OK I've looked at the source code. Does RenderBars() get called every tick update or on bar close?

Is there a full list of Fidelity PDFs;

Not only on every tick update (to update the partial bar). Think literally every time when the chart requires a redraw e.g. when you resize it or mouse over it etc.
