TO BE ANALYZED
Do we really want to have users changing the color of the zero line for indicators that have a zero line? I was thinking that we would set the zero line to true but keep everything a grey dashed line that the user cannot change, at least for now. What are your thoughts? My thought is to keep the indicators and associated code simple for developers and users. If we really want to add complex adjustments for users to make in the properties panel, we can always add the code to IndicatorNode/OverlayNode later on. I was thinking this should apply to all delimiters for now as well. It keeps the user interface consistent. Let me know if my idea is bad. If so, I'll go back into every indicator that has zero lines and delimiters and add the functionality for users to modify these settings.
