Sold-out double bottoms as a three-gate inventory test

Three gates before the reversal is live

A double-bottom is a second visit to a prior low that is judged sold out when the retest fails to recruit the volume seen on the first decline. The first test of the extreme is associated with heavy volume from a strong trend. The second test of the same level is expected to print much lighter volume even if news intensity is similar.

TradersWeek frames this, as an editorial reading, as a three-gate inventory test. The first low is where volume spent itself. The second low is accepted only if large-lot selling refuses to reappear. A downtrend-line break is the last gate before the reversal is treated as a live hypothesis.

How volume-price-analysis reads participation

Large professional participation is inferred from the pairing of price movement with daily volume rather than from disclosed positions. Volume-price-analysis asks whether large traders are adding, liquidating, or standing aside by pairing each price swing with expansion or contraction in volume.

Receding volume during a decline is treated as evidence that lower prices are not inducing long liquidation or new short selling by large traders. Existing long holders are potential sellers and existing short holders are potential buyers once price moves against those positions. That latent pressure is potential-opposing-flow.

TradersWeek adds, as an editorial reading, that a markdown on large volume can look like forced selling and later be classed as liquidation-masking-accumulation if the quiet retest shows inventory moving into stronger hands.

The trendline closes the test

A trendline is a line along successive swing highs or lows whose break is used as a discrete change-of-condition signal. In the historical workflow, a near-term uptrend-line break can mark a renewed decline attempt, while a later downtrend-line break is used as the trend-change signal.

Until that downtrend-line break, TradersWeek keeps the sold-out double-bottom, as an editorial rule, in the status of a hypothesis that has not yet cleared its last gate.

The December 1990 bond sequence

In the December 1990 bond sequence, volume expanded when price broke major support and later failed to expand on the assault of the 87-00 area. A near-term uptrend-line break labeled B marked a renewed decline attempt, and a later downtrend-line break labeled C was used as the trend-change signal.

TradersWeek maps this sequence, as an editorial reading, onto the three gates. The expanded break of support is the first-gate spend of volume. The quiet assault of the 87-00 area is the sold-out retest. The break labeled C is the last gate that turns the reversal into a live hypothesis.

A rally after the low can still fail

A post-low advance is left open as a possible one-sided psychology adjustment or short-covering bounce that can fail without forming a top if buying interest is exhausted. The inverse construction is the double-top: a quieter second test of a prior high implies the supporting news has already been discounted.
