A rounded bottom, also called a saucer, is a slow, curved base that forms at the end of a downtrend. Selling fades away, the price goes sideways for a while, and buying slowly takes over. It is a patient pattern: it can take months to form, but the breakout at the end can be worth the wait.
What a rounded bottom looks like
Picture a bowl. The price falls, the falls get smaller, it flattens out along the bottom and then starts to curve back up. Draw a line across the high on the left-hand side of the bowl. That line is the rim, and it is your trigger.
Volume often follows the same shape: heavier at the start, very quiet in the middle and picking up again as the price climbs the right-hand side.
A rounded bottom is like a cup and handle without the handle.
Why it works
The curve shows a gradual change of mood. Sellers give up slowly rather than all at once, and buyers who were waiting on the sidelines slowly come back. Because the change is gradual, the new uptrend often lasts.
How to trade a rounded bottom
- Entry: buy on a close above the rim. Some traders buy a small amount as the right side curves up and add more on the breakout.
- Stop: below the most recent swing low on the right side of the bowl.
- Target: measure from the rim down to the bottom of the bowl and add that distance to the breakout price.
Because the pattern takes so long to form, it suits longer-term traders and investors rather than day traders.
Mistakes to avoid
- Buying too early, while the price is still drifting lower along the bottom.
- Mistaking a sharp V-shaped bounce for a rounded bottom. They are different patterns with different risks.
- Expecting the breakout to be quick. Rounded bottoms often grind higher.
