Short answer

Rounding bottoms and rounding tops are gradual, curved reversal patterns that reflect a slow, steady shift in sentiment rather than a sharp turning point, tracing out a smooth "bowl" or "dome" shape on the chart. A rounding bottom develops after a decline, as selling pressure gradually eases and buying interest slowly builds, curving price back upward over an extended period.

A rounding bottom develops after a decline, as selling pressure gradually eases and buying interest slowly builds, curving price back upward over an extended period. A rounding top is the mirror image, forming after an advance as buying pressure slowly fades and selling gradually takes over.

Gradual, not sharp: The defining feature is the slow, curved transition, in contrast to the sharper peaks and troughs of patterns like double tops or head and shoulders.
Volume shape: Volume often mirrors the price curve, tapering to a low point near the middle of the pattern before gradually increasing again.
Long formation time: These patterns typically take considerably longer to complete than sharper reversal patterns, sometimes spanning many weeks or months on higher timeframes.

Because the shape develops slowly, rounding patterns are easier to identify well after they have largely played out than in their early stages, which is an important limitation to keep in mind.
