Eve & Adam double bottoms do better in a bear market than in a bull market according to the
performance rank. Failure rates are lower in a bull market though. For more information see pages 244 to 258 of the

Identification Guidelines

Characteristic |
Discussion |
|
Price trend |
Downward leading to the pattern |
|
Shape |
Two distinct valleys that
look different. Eve bottoms appear first and are wider and more rounded looking.
Adam bottoms appear after Eve and are narrow, V-shaped, sometimes with one long
price spike. Spikes that appear tend to be more numerous and shorter on Eve
bottoms. |
|
Peak |
The rise between bottoms should
measure at least 10%, but allow variations. See the figure to the right. |
|
Bottom price |
The price variation between
bottoms is small, usually between 0% and 4%. The two valleys should appear to
bottom near the same price. See the figure to the right. |
|
Separation |
The twin valleys are several
weeks apart with most falling in the 2 to 7 week range; wider than 7 weeks and
performance deteriorates. See the figure to the right. |
|
Confirmation |
The double bottom confirms
as a true double bottom once price closes above the peak between the two valleys.
That is the top red line on the figure to the right. |
|
Volume |
Evenly split between the right
and left bottom showing heavier volume. |

Trading Tactic |
Explanation |
|
Measure rule |
See the figure to the right. Compute the height from the
highest peak (A) to the lowest valley (B) in the pattern then multiply it by the
above “percentage meeting price target.”
Add the result to the breakout price (the highest peak in the pattern, A) to get
the target, C. |
|
Price reversal |
Price must have something
to reverse, so if the decline leading to the double bottom is small, expect a small
rise. |
|
Big W |
Look for a double bottom with a
tall left side, one with a steep decline and few or no price consolidations along
the way. Expect price to return to near
where the downtrend began. |
|
Confirmation |
Wait for confirmation – price
to close above the peak between the valleys. If you don’t wait, there’s
a 64% chance that price will continue
lower without confirming the double bottom. |
|
Handle |
See the figure to the right. Sometimes price will confirm
the double bottom then waffle up and down, forming a handle. When price breaks out
of this region, it often moves up in a strong trend. |
|
Flat base |
Expect a large rise if the double
bottom appears after a long, flat base. Use the weekly scale to find the flat base
– the double bottom will look like
a pothole in a road. |
|
Trends |
A short-term decline leading to
the double bottom results in the best postbreakout performance. |
|
Yearly low |
Double bottoms within a third of
the yearly low
perform best. |
|
Volume trend |
A downward volume trend suggests
good postbreakout performance. |
|
Throwbacks |
Throwbacks hurt postbreakout
performance. |

Example
The above figure shows an example of an Eve & Adam double bottom chart pattern. The Eve bottom has three days
at about the same price level. Adam bottom has a long, single price spike. The two bottoms look different. Eve
is wider than Adam and more rounded looking. The Eve & Adam double bottom chart pattern confirms when price closes
above the high between the two bottoms, shown here as the breakout point.
