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 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.]
I'll give it a whirl. Here's a pic of a volume chart next to a unirenko on today's Sep ES. Glean what you can of it.
I once spent a couple of hundred hours looking at "point and figure" and reading about it, but thought better of it (still don't really know what I might be missing, there: some people swear by it - others swear at it).
I suppose it is just a matter of what you find out there that makes sense to your own head. Time-based charts I could never read properly. The renko-types suit me well.
