Very interesting, Prof. I've never read about this approach before. I haven't read that long thread yet, but I will. AmiBroker isn't set up for volume bars and I'm not sure how hard it would be to set them up or whether or not it's possible with IQFeed or IB Feed, but I'll look into it.
What's the bottom indicator? And the zig-zag yellow line is just a zig-zag or something else? It looks like you just trade based on S/R with no averages, channels, etc.?

I like constant volume bars, because it filters some of the noise produced by time charts during congestion periods. However I'm beginning to question if constant volume bars are perfect, and if it accurately displays the relationship between price & volume. For example, after reading bolter's thread (http://elitetrader.com/vb/showthread.php?s=&threadid=63202) about volume profile, he clearly demonstrates the lack of volume (a valley) at a certain price is just as important as a peak in volume. Constant volume bars are great when there is a lot of volume to measure price action, but when volume is low and there is volatility in price you end up with a lot of wide range bars similar to time charts, and the only way to compensate for this is to zoom in by using a smaller interval to see the price action. So the problem becomes what interval is right for current market conditions. Just my 2 cents.

The problem with volume bars, I found Pro Logic is that they don't get cut at the right volume because of block trades. This happened to me in both Esignal and Sierra Chart. According to a post a ways back from you, if they aren't consistent that's no good. I am going off memory, but I do recall a post of you made in about a month ago. I don't know if multi charts can cut a bar at exact volume, but if Esignal can't that seems to be a problem with using volume bars.
I did appreciate your taking the time to educate us.![]()

I had a longer look at your chart and I have to say this is one of the most helpful things I've seen posted on ET. How do you define your setups and what makes one aggressive and another conservative? What's PPF?

The only software I know that builds the bars correctly is Ensign and MultiCharts. I've been told that Sierra does but have been unable to verify that yet. You are correct. If the software doesn't cap the bars to the exact number of contracts or shares designatied per bar then then clarity the volume bars offer is rendered useless.
Ensign is a pain to use because of the "refresh" feature.

Any knowledge of TradeStation's CVBs? Does TS cap at the number of contracts specified? Thanks...
