Adam and Eve bottom
A double bottom where the first low is a sharp V and the second low is a rounder, wider curve.
What it shows
It is a double bottom with two different shapes. Adam is the first low: a sharp, narrow drop and recovery. Eve is the second low: wider and rounded.
The names come from chart pattern books. The pattern is complete only when price closes above the high between the two lows.
How we find it
The same code that draws it on your chart follows these steps, with the same result every time.
- Find a double bottom (two lows within 3% of each other).
- Measure the width of each low at 3% above it.
- Mark the first low as Adam if it is under half the width of the second.
- Mark complete when a close rises above the high between the lows.
Starting values: Low match within 3%; Width ratio second low at least 2 times wider; Margin 1.0%. These are proposed and will be tuned on real price data before launch.
How to read it
- The first low (Adam) is a sharp V.
- The second low (Eve) is a rounded curve.
- The dashed red line is the top of the bounce between them.
