The Eve & Eve double top is the best performing of the Adam and Eve combinations of double tops. It has a large break even failure rate but a decent decline and large rise after the trend ends. If you can tell when price has bottomed, then that's the time go buy. The Eve & Eve double top is what most chartists call the classic double top. For more information see pages 321 to 334 of the book Encyclopedia of Chart Patterns, Second Edition and the following...

Identification Guidelines

Characteristic Discussion
Price trend Upward leading to the pattern
Shape Two distinct tops that look similar. An Eve top is rounded and wide looking, but sometimes has several short spikes poking out.
Valley The valley drop between the tops should measure at least 10%, but allow exceptions. The figure to the right shows this for a typical double top chart pattern.
Top price The variation between price peaks is small, less than 3%. The two tops should appear to peak near the same price. The figure to the right shows this for a typical double top.
Separation The twin peaks are several weeks apart with most falling in the 2 to 6 week range. The figure to the right shows this for a typical double top.
Confirmation The double top confirms as a true double top once price closes below the valley between the two peaks. The lowest red line on the figure to the right shows this.
Volume Usually higher on formation of the left peak.

Trading Tips

Trading Tactic Explanation

Measure rule

Compute the height from the highest peak (point B on the chart to the right) to the lowest valley (A) in the pattern then multiply it by the above “percentage meeting price target.” Subtract the result from the breakout price (A) to get the target (C).
Price reversal Price must have something to reverse, so if the rise leading to the double top is small, expect a small decline.
Confirmation Wait for confirmation – price to close below the valley floor (point A in the figure to the right). If you don’t wait, there’s a 65% chance that price will continue higher without confirming the double top.
Trend end If a double top appears after a long-term decline (that is, an upward retrace in a falling price trend), confirmation of the top may mean that the end of the decline is near (10% to 20% below and a month away).
Trends A short-term rise leading to the double top results in the best postbreakout performance.
Yearly high Double tops within a third of the yearly high perform best.

Volume trend

The volume trend has no influence on postbreakout performance.

Pullbacks

Pullbacks hurt postbreakout performance.

Example

Eve & Adam double top chart pattern example

The above figure shows an example of an Eve & Eve double top chart pattern. Both Eve tops appear rounded, wide, not narrow and pointed like their Adam counterparts. The Eve & Eve double top confirms as a true double top when price closes below the confirmation line, shown in the above chart as a blue horizontal line. A pullback brings the stock back to the breakout price before the decline resumes.
