Lower highs and higher lows squeezing into a point — a coiling market that has not chosen a side yet. Trigger: A close outside either boundary. The direction of the break is the signal — the pattern itself does not predict it. Invalidation: Price closing back inside the triangle after breaking out — a common trap in low-volume breaks.
