## Volume Shapes: Summary

Volume has in five distinct shapes but two types appear most often during the formation of chart patterns: U and dome. The other shapes, up, down, and flat, I lump together as a random shape because they are rare. Think of the random volume shape as not U and not dome.

Usually, the volume shape is obvious except in long chart patterns, such as rounding turns, which may have several volume shapes. Use the most recent volume shape (the volume shape closest to the breakout) as the determining pattern. At the end of this page is a table of patterns that don't have a volume preference.

## Volume Shapes: U-shaped volume

Volume is higher at the ends of the chart pattern than in the middle. Usually, the volume peaks correspond to price turning points in the chart pattern. U-shaped volume has the most chart patterns in its list – 27. The following table shows which chart patterns do better post breakout with U-shaped volume.

Triangles, descending, up breakouts. Triangles, symmetrical, up breakouts (tied with dome shape) Triple tops Wedges, rising, up breakouts

## Volume Shapes: Dome shaped volume

Dome shaped volume is the inverted version of the U-shape. Volume is higher in the middle of the chart pattern than at the ends. Dome shaped volume has 17 patterns in its list, the smallest of the three shapes. The following table shows which chart patterns do better with dome-shaped volume.

## Volume Shapes: Random volume shape

A random volume shape is one that is not domed and not U-shaped. It may be flat, inclined, declined, or just have a rugged appearance with no discernable shape. The random volume shape has 20 entries in its list, second only to the U shape. The following chart patterns perform better with a random volume shape.

 Chart Patterns in a bull market Broadening bottoms, up or down breakouts Broadening formation, right-angled and descending, down breakouts Broadening wedge, descending, up breakouts Diamond bottoms, down breakouts Diamond tops, up breakouts Double tops, Adam & Adam Double tops, Eve & Eve (tied with U-shape) Flags, up breakouts Flags, high and tight Head-and-shoulders bottoms (tied with U-shape) Island reversals, down breakouts Rectangle bottoms, up or down breakouts Rectangle tops, up breakouts Rounding bottoms Scallops, descending, down breakouts Triangles, ascending, up breakouts.

## Volume Shapes: No Performance Difference

The following chart patterns show no volume shape preference. That means performance is the same across all volume shapes.
