Volume-confirmed reversal patterns, stops, and measured objectives

A formation that names its own plan

Pattern geometry is presented as a way to add plan discipline by deriving both a price objective and a protective invalidation level from the formation itself.

Neckline-confirmation treats a top or bottom as live only after price breaks the line joining the intervening swing lows for a top, or the intervening swing highs for a bottom, preferably with expanding volume. The measured-move is the minimum objective taken by projecting the vertical distance from the extreme, the head or the twin peak, to the neckline or support, starting from the break point. The invalidation-stop is the price just beyond the right shoulder or second peak that cancels the pattern hypothesis if crossed.

Volume-fade is weaker activity into the right shoulder or second test of resistance, read as demand that cannot match the first attempt. An open-interest-filter reads a late rally on falling open interest as short covering, not fresh buying, and weakens the case that a new high will hold.

Textbook volume on tops

In a textbook head-and-shoulders top, volume is typically heaviest on the left shoulder, lighter through the head and right shoulder, and expands on a break under the neckline. The projected objective equals the vertical distance from the head to the neckline.

In a textbook double top, volume is strongest on the first drive into resistance, weaker on the second test, and the minimum objective after a support break equals the distance from the peaks to that support line.

Completed tops in the archive cases

On the June 1988 British pound chart, the advance into the head at point 3 occurred on volume well below the two earlier peaks and with declining open interest. The upward-sloping neckline then broke on May 17 as prices fell on heavy volume, which was treated as confirmation of the top. Invalidation was placed above the right shoulder at point 4, and a downside objective in the 179-180 area was measured from the head-to-neckline height. Later lows formed in the 166-168 area.

On August 1988 crude oil, three-day volume into the first peak totaled 238000 contracts versus 165000 into the second peak, about a 30 percent decline. A negative key reversal at the second high and a later break of 1765 were used to confirm a double top, even though that break day closed higher.

On the December 1988 Canadian dollar, the right-shoulder rally lasted seven days, about half the prior up-leg, while open interest fell and broke its uptrend. A high-volume gap through the neckline confirmed the head-and-shoulders top, with a measured target of 8010 and invalidation placed just above the right shoulder at 8290.

When the inverse head-and-shoulders aborts

July 1988 cocoa built a potential inverse head-and-shoulders with neckline resistance near 1630. The right-shoulder dip toward 1570 came on declining volume, then price crossed 1630 on very heavy volume before reversing back through that neckline two days after the illustrated chart ended, on volume heavier than the breakout.

After cocoa cleared 1630, the critical protective level was moved to just under that neckline, so the later plunge back through it would have exited the long once the bottom formation aborted. The aborted-bottom-rule is that if an inverse head-and-shoulders triggers and then fails back through the neckline, that former breakout line becomes the exit, not a reason to stay long.
