Describe the pattern precisely
A conventional head-and-shoulders formation shows three peaks, with the middle peak higher than the others, separated by intervening lows. A neckline connects the relevant lows; an inverse version reverses the shape. Real charts rarely resemble perfect diagrams. Define acceptable variation in timing, height and neckline slope before searching for examples, or the pattern can become whatever a reviewer wants to see afterward.
Confirmation does not remove uncertainty
Some researchers study a neckline break as confirmation of a possible trend reversal, while others examine a later retest. Each choice changes entry timing, missed opportunities and failure risk. The measured height of a pattern is sometimes used to project a target, but that projection is not a price obligation. Liquidity, gaps and broader market conditions can overwhelm the apparent chart structure.
Keep recognition and results separate
First identify candidate patterns using consistent rules, then evaluate outcomes without redrawing the pattern after prices move. Include failed breaks and ambiguous formations, and account for costs and execution delay. Historical research does not establish that a pattern will work in every market. FYLU presents this method as technical-analysis education and does not supply validated pattern detection, live alerts or an expected success rate.
