Eve-Adam double bottoms as a two-step classroom test

Among mixed double-bottom pairings, Eve then Adam is the scarcest. Identification starts with a wide, rounded left low and a narrow spiked right low under the usual screens. The structure is not complete until a close above the middle peak, and overhead congestion can still halt the later advance.

  • Among the four Adam-and-Eve double-bottom pairings, the Eve-then-Adam pairing is the scarcest, and usable examples were hard to collect.
  • The pairing is recognized when the lows do not match: a wider, flatter Eve bottom on the left and a narrow, V-shaped Adam bottom on the right.
  • Volume is heavier on the right low only 52 percent of the time, so an atypical volume sequence is not a reason to reject the pattern.
  • The structure is not complete until a confirmation close above the peak between the lows, after which overhead congestion can still halt the advance.

The scarcest mixed pairing

Among the four Adam-and-Eve double-bottom pairings, the Eve-then-Adam pairing is described as the scarcest, and usable examples were hard to collect.

The pairing is recognized when the two lows look different. The left low is an Eve bottom: wider, flatter, and more rounded. The right low is an Adam bottom: narrow and V-shaped. Together they form an Eve-Adam double bottom whose bottoms do not match each other.

Prove the left low is wide

Identification can start with width. An Eve bottom may contain several minor troughs, while an Adam bottom is often a single-session spike. Nearby chart swings can be used as a shape comparison.

Standard screens still apply: a prior decline into the pattern, lows near the same price, an intervening rise of at least 10 percent, and bottom separation of about three weeks or more. A one-day shortfall from the three-week spacing can still be accepted if the two lows are not packed too closely.

Volume is heavier on the right low only 52 percent of the time. An atypical volume sequence is not treated as a reason to reject the pattern.

What is not this pairing

A pair of lows that differ by 11 percent in price is not treated as this double-bottom variety. Lows that form while price is already rising into the structure are also not treated as this variety.

Wait for the confirmation close

The structure is not treated as complete until price closes above the peak between the two lows. That confirmation close is a close above the highest point between the two lows.

When the same decline also prints a third low, the confirmation level implied by the last two bottoms sits below the confirmation level of the three-bottom reading.

Scan for overhead congestion

Overhead congestion above the pattern can halt the post-confirmation advance. A later 20 percent drop from that stall high is used to mark a trend change.

That stall high is the ultimate high: the highest high reached after the breakout before the later 20 percent decline.

Global Industries Eve-Adam lows versus the 13.06 confirmation

Weekly prices traced from the daily bars on the Global Industries chart, July 2000 through June 2001. The wide October trough is the Eve low and the December spike is Adam. A trader should still withhold the reversal until a close through the 13.06 midpoint high named in the article; the March stall at 16.25 and drop to 12.44 then show how the June–July congestion overhead can stop the advance.

Vertical scale locked to levels the article states in prose: 13.06 double-bottom confirmation, 14.81 triple-bottom confirmation, 16.25 ultimate high, 12.44 next low. Other weekly points are read from the printed bars and are approximate to about 0.1. Unlabelled volume bars were not converted.
