Double Top: The 'M' That Warns You to Leave

The shape

A rally makes a high, dips, rallies back to the same high — and fails again. When price then breaks the dip between the peaks (the neckline), the "M" completes.

Why it works

Twice the buyers charged the same ceiling; twice they were absorbed. Everyone who bought near those peaks is now trapped at a loss, and their selling — "just let me out at breakeven" — caps every future rally. The neckline break tells you the floor of that battle has given way.

How to use it (honestly)

For most investors this is a defensive signal, not a trade: if a stock you hold prints a confirmed double top, tighten your stop, book partial profits, or at minimum re-read the bear case on its stock page. Short-selling the breakdown is a professional's game with its own risk rules.

Our scanner's rules

• Two swing highs within ~3%, adequately separated in time.
• Signal only on the neckline breakdown, with the invalidation level above the higher peak.
• Measured objective: the pattern's height projected below the neckline.

Common mistakes

• Calling every pause a double top — in strong uptrends, stocks routinely rest at a level then punch through. The pattern needs the *breakdown*, not just the twin peaks.
• Ignoring it because "the fundamentals are great." Price topping on heavy distribution has ended many great-fundamentals stories.
