New user here, so I don’t know if this has been suggested before. Not as far as I searched for it anyway.
I would like to make a suggestion for adding just a little bit of extra useful information that would help when building slowly into a position and averaging on the stock price. The current chart showing the green line is pretty useful already, but it’s detached from context as far as day of purchase goes, which brimgs useful perspective.
I’m thinking along the lines of what I get in the Fastgraphs analytical tool. Simple green for bought and red for sold markers.
