Definition
A topping pattern is any chart formation that marks the end of an uptrend — the region where an advance loses momentum and begins to turn down. It is the upper-extreme subset of reversal patterns. The double top, the head-and-shoulders top, the rounding top, and the blow-off top are all topping patterns.
In market terms, a top is where distribution occurs: the buyers who drove the trend up gradually hand their holdings to a shrinking pool of new buyers. When that pool is exhausted, the advance stalls and the topping pattern takes shape.
Why it matters
How it works
As an uptrend matures, each new high is met with more selling and less follow-through. Price churns near the peak as eager buyers and profit-taking sellers trade control back and forth, producing the characteristic shapes — twin peaks, a head flanked by shoulders, a slow dome. The topping pattern is confirmed only when price breaks below the support level that the formation defined; until then the uptrend is merely paused, not over.
Tops are notoriously harder to read than bottoms because they tend to form gradually and with many false alarms.
