Primary keyword

double top

Works best for

At clear support/resistance levels

Failure condition

In strong trends (often becomes continuation)

Plain-English explanation

Double tops and bottoms are like price saying "I tried twice and couldn't do it."

Double Top (M shape): - Forms at resistance after an uptrend - Two peaks at roughly the same level - Signals trend reversal from bullish to bearish - Confirmed when price breaks below the middle trough

Double Bottom (W shape): - Forms at support after a downtrend - Two troughs at roughly the same level - Signals trend reversal from bearish to bullish - Confirmed when price breaks above the middle peak

Why they work: The first top/bottom shows strong supply/demand. The second test that fails shows the market can't push through. Failure often leads to reversal.

Important: The two peaks/troughs don't need to be exactly equal. Within 3% is close enough.

How it works

Price tests a level, reverses, then tests again. The second failed test shows exhaustion. Traders who bought the first dip start selling, and traders who shorted at the first top add to positions, creating the reversal.

When it works best

  • At clear support/resistance levels
  • After extended trends
  • With divergence on oscillators (RSI, MACD)
  • When second test has lower volume (exhaustion)
  • Medium to higher timeframes

When it fails

  • In strong trends (often becomes continuation)
  • Without proper confirmation (wait for break)
  • On very short timeframes
  • When peaks/troughs are too far apart
  • If forced onto consolidation ranges

Common mistakes

  • Trading before confirmation (wait for neckline break)
  • Expecting exact price matches
  • Ignoring the prior trend
  • Not checking volume pattern
  • Setting stops too tight

Pro tips

  • Wait for the break of the middle pivot
  • Second peak with divergence = higher probability
  • Often get a retest of the broken level
  • Measure target from pattern height
  • Triple tops/bottoms are even more powerful
