Quote from ProfLogic:
Time is a variable that doesn't exist on a Volume Bar Chart (VBC). A VBC is a perfect view of price movement uncorrupted by any and all variables in the market. Since it is so clean the oscillations are smooth, methodical and easy to read. The advantage is you are looking at pure price movement. The markets aren't traded in specific time increments (those are major variables). The markets are traded in share or contract increments and those are represented in the markets as price instruments.
A detailed description on how to read and use VCB's is in this thread: http://www.elitetrader.com/vb/showthread.php?s=&threadid=80582&highlight=Odd+Tick
The chart I posted is simply an entry and exit version of the Trend Chart for the eMini S&P. I'm posting the Trend chart for today. All of the labels; price, oscillation outcomes, trend lines and trend designation are all created in real-time by my computer program. The written labels are added by me showing the trade set-ups and execution points that were created today from this chart.

There is no such thing as a specific minute chart for volume bars. Each bar is a specific number of contracts traded. In the case of the posted chart, it is a 343 Volume Bar Chart. The times are marked and the time line is at the bottom for comparison of time.
I don't use minute charts because the markets aren't traded based on time they are based on price and read in volume.
Hope this helps.

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.?

Hi BlueDemon77,
Amibroker does have N-volume bars built in, although I haven't used them.
This is from v4.80
TimeFrameMode( 2 );
- switches time frame functions to N-volume bar operation (positive values passed to TimeFrameSet are treated nowas N-volme bars)
Example:
TimeFrameMode( 2 );
TimeFrameSet( 50000 ); // 50'000 share bars..
...do something ...
TimeFrameRestore();
