Having researched them and published a few articles on them I can honestly say they are far superior to time based bars because they do not contain any inherent variable aspect like typical charts contains. The markets are traded in volume, NOT TIME. The problem with getting the industry to look at this chart type is that a majority of "market professionals" are closed minded. Thanks for opening the door a bit. Wm Schamp I invented volume bar charting 7 years ago.

Like bending the vertical lines so the time lines on the bottom shift to their counterparts' exact time above. That would clearly illustrate the compression factor (multiple activity bars into time slots when active, fewer when not), without having to go thru and count minutes between % bars on the bottom. Probably a bit more complex then a normal graph, however. ==Bob D.

Sorry, I should know the answer to this but I don't! I'll look into it if I get the time.

It is such an interesting diagram, thank you for sharing Felix. RussAbbott is right – the process only lends itself to ex ante analysis.

Before that you won't know what percentage of the day each hour of trading produces. You can’t make this sort of graph until the day is over.

When you plot with hi/low bars you get a "thick line" result that tends to hide smaller bumps. It does seem “smoother”, however I would guess the reason for this is the difference in plotting styles.
