Similar formations and limits of one example
Two nearby highs without sufficient pullback and a closing boundary break are not a completed double top. The shape identifies an event to research. It does not predict the next move or provide a trading signal by itself.
One formation does not establish the probability of a move. The historical comparison measures outcomes against a comparable background for each configuration.
