Rounding Bottom

Also called: saucer bottom

A slow, U-shaped reversal where a downtrend gradually curves into an uptrend — a 'saucer' base that signals a shift in control.

Schematic of a rounding bottom — illustrative geometry, not a live price chart.

A rounding bottom (or saucer) traces a gradual, bowl-shaped transition from selling to buying over weeks or months. Volume often mirrors the price, drying up at the bottom and picking back up as the right side lifts.

The pattern completes on a breakout above the level where the rounding began, ideally on expanding volume. Its slow, orderly shape suggests a durable change in trend rather than a sharp snap-back.
