I did my best to look around but i think a more dedicated volume profile set up similar to what is in the tpo chart but a stand alone that could be applied to different charts or even be a chart itself. I am aware you can set a drag range for that but I this area should be explored much more… ideally a session volume could be presented with a fixed composite at end much like a post from paid2fade here about where he wanted a larger composite of the tpo volume profile to sit and ideally we could customize the time frame by however many days, weeks or months beyond just the drawing so to speak.
