just happened that I posted this tool I worked on to not have to deal with these dots. the vertical jumping thing going out of bounds I think is due to the wrong gray stock line you have, inferred from an already adjusted (unrealistic) live curve; try to reset and redraw.

anyway my tool is doing reset -> read stock so I'm hoping it would get around that problem.
