Technical Definition
The Butterfly Pattern is a harmonic reversal pattern that forms at market extremes, where price extends beyond the starting point of the original impulse move. Unlike Gartley and Bat patterns, the Butterfly completes outside the XA leg, typically at a 127.2% or 161.8% Fibonacci extension of XA. This extended move signals potential exhaustion and a high-probability reversal zone when confirmed.
It looks like the letter "W" or "M", but the last leg stretches out further than the start. It catches people who think the trend is breaking out, only to reverse sharply.
Reversals often occur at extended price extremes
