Does anyone know how to add a trendline or average line to charts? For example, if I'm looking at the TTM P/S over the past 10 years, I want to have a line pop-up that shows the average P/S over those 10 years. I hope I'm explaining this well. I know YCharts has a feature like that. I'm hoping Koyfin does too and I just haven't been able to find it.
