Classical Chart Patterns
When a trend turns
Trends do not stop the way cars stop. They stop the way a crowd leaves a stadium: the leaders slow, the back rows keep pushing, the direction stays the same for a while although the intent has already changed. Reversal patterns are the shapes that motion makes — and the reason they work is not geometry. It is that each shape is a legible record of the crowd running out of people.
Murphy is strict about this and beginners routinely ignore it. First, a reversal requires a PRIOR TREND to reverse — a "head and shoulders" inside a six-month range is a coincidence of shapes, not a signal. Second, the pattern is not a pattern until a key level BREAKS: the drawing is a hypothesis, and the break is the evidence. Third, the LARGER the pattern in both time and height, the larger the move that follows. A three-day formation predicts three days of movement, which after costs is usually not worth trading.
- LEFT SHOULDER: a normal advance in the uptrend, on healthy volume, followed by a normal pullback. Nothing is wrong yet.
- HEAD: a higher high — but on lighter volume than the left shoulder. The trend is still working and already fewer people are pushing it.
- RIGHT SHOULDER: a rally that FAILS to exceed the head, on the lightest volume of the three. The crowd has stopped recruiting; this is the warning.
- NECKLINE BREAK: price closes below the line joining the two intervening troughs, ideally on expanding volume. Now it is a signal, and the earlier bars were only preparation.
- MEASURED OBJECTIVE: take the vertical distance from the head down to the neckline, and project it downward from the break point. Treat it as an estimate for planning targets, not a prophecy.
A double top is two peaks at roughly the same price with a trough between them: the crowd tried twice and could not get through. The confirmation is the break of the intervening trough, and the measured objective is the pattern's height projected down from that break — exactly the same arithmetic as head and shoulders. Two details separate a real one from wishful thinking: the peaks should be separated by enough time that the second attempt is a genuinely new attempt (weeks on a daily chart, not two bars), and the second peak should come on lighter volume. Doubles at very different volumes are usually just a range.
After the neckline breaks, price very often comes back to touch it from the other side before continuing. Beginners read that bounce as "the pattern failed" and cover. Professionals read it as the mechanism of the pattern completing: the broken support has become resistance, and the return move is where the people who did not sell at the top get their second chance — and take it. If you missed the break, the return move is the higher-quality entry, because your stop can sit just above the neckline instead of far below your entry.
The right shoulder is visible and the story is compelling and you have not yet been paid, so the temptation is to short there. But until the neckline goes, what you are looking at is a normal pullback in a live uptrend — and normal pullbacks in live uptrends resolve upward far more often than not. Pre-empting the break turns a pattern with a defined invalidation into a guess with an undefined one. Wait for the close beyond the level; you give up a few percent of the move and you remove most of the ways to be wrong.
A meaningful share of textbook patterns break the wrong way or break and immediately reverse. This is not a flaw in the method; it is why stops exist. It also produces one of the most reliable setups in technical analysis: when a widely-watched pattern fails, everyone who traded it is offside at once and must exit, which fuels a sharp move in the opposite direction. A head and shoulders that breaks down and then closes back above the neckline is not a broken tool — it is a signal, pointing the other way.
Every reversal pattern in the book is the same observation drawn at different lengths: the trend attempted a new extreme and failed, and the failure was accompanied by fewer participants. Head and shoulders shows it in three acts, a double top in two, and a single failed high in one. Learn to see the participation dying and you no longer need to memorise the catalogue — you will recognise formations that have no name.
A head and shoulders top has its head at 120 and a neckline at 100. Price closes at 98. What is the measured objective, and what would make you abandon it before it is reached? (Objective: 100 − (120 − 100) = 80. Abandon it on a close back above the neckline at 100 — that turns a completed pattern into a failed one, and failed patterns tend to run hard against the people still holding the original trade, which would now include you.)
A reversal pattern needs a prior trend, a broken level, and enough size to be worth the costs. Head and shoulders and double tops are the same story at different lengths: a failed new high with thinning participation, confirmed only by the break of the neckline or the intervening trough. Measure the objective by projecting the pattern's height from the break, expect a return move to the broken level, and treat a failed pattern as a fresh signal in the opposite direction rather than as a broken tool.
Find one completed head and shoulders or double top on any chart from the last two years. Mark the neckline, the break bar and the measured objective, then check three things: did volume shrink across the peaks, did the objective get reached, and was there a return move to the neckline? Do this for five patterns and you will have a personal base rate — which is worth more than any claimed success rate you read in a book, including this one.
