Can you post an example of a volume chart?
You'll perhaps think it sounds strange, but with apologies, I'm not allowed (by my NDA) to post charts in a forum. Doubtless someone else will oblige.
(Actually I have seen volume charts posted here in other threads, incidentally).
I'll be able to tell you straight away if i'd consider switching.
I suspect not, realistically:
they look superficially exactly the same as any other chart, anyway: the difference is simply in the inputs from which the bars/candles are constructed.
In other words, there's nothing about the appearance of the charts that would enable you to decide whether or not to use them: only your overall comparative results from using them for a statistically significant time can determine that.
Appearance is irrelevant, overall: only outcomes matter.
[I appreciate, of course, that you know this already, but for the benefit of anyone with less experience reading the thread, I'll just clarify that the closing of each bar/candle and the opening of the next is defined not by the passage of a specified unit of time (as with time charts) or by the transacting of a specified number of orders (as with tick charts), but by the transacting of a specified volume, and if a single, large order exceeds the instant bar's/candle's limit, it's shown effectively as if it were divided between two bars/candles.]
