Hello

Currently, Designer support custom indicator (and their painter) only via app.config file. It means you need extract your code into dedicated assembly and add into Designer.exe.config the following code:

I'm trying to use a custom indicator in designer and use the indicatorPainter to display it. I assume it can be done, but the helps are not real clear. I have the indicator returning a SingleIndicatorValue where ValuesClass is a class that contain the multiple values to chart (values for 6 lines) In the strategy, I have ChartElementForIndicatorPainter = new ChartIndicatorElement(); ChartElementForIndicatorPainter.IndicatorPainter = new ValuesClassIndicatorPainter(); This is as far as the help gets me. It doesn't even say where this should go. I added it to the strategy initialization.

In the OnStarted method I add it to the chart chart.AddElement(area, ChartElementForIndicatorPainter);

But then in the "OnProcess" method, when I call NewIndicator?.Invoke(indicatorReturn); It gives me 2 errors.

In debugging it externally, it never hits the breakpoints of the indicatorpainter, though I don't know if it ever would anyways. It obviously is not using the painter if it is trying to change the class into a decimal.

Is it possible to use the indicator painter with the designer? How do you hook it up? The helps are pretty sparse about this.
