Bulkowski's Volume Pattern Resource

My book, Encyclopedia of Chart Patterns Second Edition, shown on the left, discusses the performance of 63 chart and event patterns. There is no better reference book on the subject. Each pattern chapter includes a table of volume statistics, if applicable.

If you click on the above link and then buy the book (or anything) while at Amazon.com, the referral will help support this site. Thanks.

This page is the main gateway for volume patterns. Some believe that volume plays an important role in technical analysis. My studies of volume and chart patterns shows that it adds value, but I usually ignore it.

These links provide much more information on volume.

• Volume. The definitive guide to volume preceding the breakout.
• Volume, breakout day
• Volume shapes
• Volume trends

I have a brief review of the results from studies, namely:

• New volume study. After a high volume breakout, performance doesn't improve much but failures triple.
• Does a rising volume trend within the chart pattern result in the best performance?
• What is the best performing volume shape?
• Does heavy breakout volume mean better performance?
