Hide / Unhide parameters in Strategy Analizer

[fercho]

Hi

I can't get work case number 1 from "SampleIndicatorTypeConverter" example when put into my strategy.

The bool "Activate" can't being recognized. I just want to hide V1 and V2 after "Activate" box is selected in Strategy Analyzer Parameters.

Sorry for asking but I being working on it all day long and I get stuck every time

Best regards,

Fernando

Hello fercho,

Unfortunately, typeconverters do not work in the Strategy Analyzer.

In order for a property to be optimizable, we need to use the NinjaScriptProperty attribute. This does not play nicely when using a TypeConverter to customize property grid behavior:

1. Even if a property is toggled off, it will still display in the Settings Display
2. Applying NinjaScriptProperty attribute to toggling property breaks toggling behavior.
