Rounding Bottom pattern
A rounding bottom, or saucer bottom, is a gradual U-shaped turn from falling prices to rising ones. It reflects selling pressure fading slowly rather than a sudden reversal.
How to identify a rounding bottom
- A prior decline that slows down rather than ending abruptly.
- A broad, curved base with no single sharp low.
- A gradual rise back towards the start of the decline.
What confirms it
A close above the high where the decline began, or above a clear resistance level on the right side.
What invalidates it
A fall back below the centre of the base.
How traders project a target
Add the depth of the base to the breakout level as a reference.
Common mistakes
- Calling a rounding bottom too early, halfway through the base.
- Confusing a sharp V reversal with a rounding bottom.
- Expecting it to work on very low timeframes, where it is rarely clean.
Where it appears
Most common on daily and weekly charts. It usually takes a long time to form.
Frequently asked questions
How long does a rounding bottom take to form?
Usually a long time relative to the timeframe. Its slow shape is what distinguishes it.
Is a rounding bottom the same as a cup?
The shapes are similar. A cup and handle adds a small pullback (the handle) before the breakout.
Where is a rounding bottom confirmed?
On a break above the level where the original decline started.
