Rounding bottoms & tops (saucers)

A reversal in slow motion

A rounding bottom (or saucer) is a reversal that happens gradually, with no sharp V or neckline. Price drifts down, flattens, and curves smoothly back up in a long U — selling pressure quietly giving way to buying. A rounding top (a dome) is the mirror: a slow arch that rolls from buying to selling.

The key level is the rim — the price where the curve began, which becomes resistance (bottom) or support (top). The pattern triggers when price breaks the rim. Enter the break or its retest, stop just beyond the rim, and target the depth of the bowl projected from the rim. Because they form slowly, saucers are easy to miss — but they often precede very large, durable moves.

• Rounding bottom = a slow, smooth U reversal (saucer). Rounding top = the dome.
• No neckline — the trigger is the break of the rim (where the curve began).
• Enter the rim break or retest; target = the depth of the bowl.
• Slow to form and easy to miss, but often mark major turns.
