Definition
A rounded pattern is a slow, smooth reversal in which price curves gently from one direction into the other, tracing the outline of a saucer or a dome. A rounding bottom shows a long, gradual decline that flattens and then slowly turns up; a rounding top shows the same arc inverted at the end of an advance.
It is the opposite extreme from a V-pattern. Where a V reverses in a single sharp turn, a rounded pattern takes weeks or months to change the market's mind. The gradual shape reflects a slow, deliberate shift in the balance of supply and demand.
Why it matters
How it works
The pattern develops as one side of the market loses dominance gradually rather than suddenly. In a rounding bottom, selling pressure slowly dries up, price stops falling, drifts sideways, and then begins to rise as buyers take over — producing the smooth curve. Volume frequently traces a matching saucer, fading toward the low point and building again as the new trend gains strength.
Because the formation is slow and visible, it can offer a relatively reliable signal — but it also requires patience, and the curve is only clear in hindsight.
