Rounding bottoms are chart patterns that are difficult to spot unless you look on the weekly scale. The break even performance rank is small and the average rise is large, so they show good performance.

Be careful midway through the turn since price sometimes shoots up only to drop back down.

Rounding Bottom: Identification Guidelines

CharacteristicDiscussion
Weekly or dailyThe pattern appears on either the daily or weekly chart. Concentrate on finding them on the weekly scale because the rounded nature is more apparent.
Price trendPrice trends upward to the pattern 66% of the time (that is, 66% act as continuation patterns).
ShapeLook for a rounded bowl shape, usually over many months and usually after an upward price trend.
BumpPrice may shoot up midway through the turn, near the bottom, but price usually retraces most (not all) of the way back to where it started. The Bump figure to the right shows an example as does the figure at the bottom of this page.
ConfirmationI use a close above the left peak because price on the right might not pause at a minor high.

Rounding Bottom: Trading Tips

Consult the associated figure on the right.

Trading TacticExplanation
Measure ruleCompute the height from the left saucer lip to the lowest valley in the pattern then multiply it by the above 'percentage meeting price target.' Add the difference to the right saucer lip to get a price target. If the saucer doesn't have a right lip then use the left rim. The Measure Rule figure to the right uses the left lip (A) to the lowest valley (B) as the height.
SwingersSwing traders can sell if price bumps up midway through the rounding turn. Buy back in once price retraces back to near the price at which the bump started. Price usually re-enters the rounding turn higher than the price of the bump start.
PausePrice often pauses at the price level of the left saucer lip.
HandleIf the rounded bottom forms a handle at the right saucer lip, draw a trendline from the left lip to the right and extended downward beyond the handle. Buy when price closes above the trendline. The Handle figure to the right shows this situation. The red line is the trendline connecting the left rim to the right rim and extended downward. Don't use this method the line sloped upward.
Flat baseA flat base (predominantly flat over several months) leading to the rounding turn often leads to a powerful rally. The Flat Base figure to the right shows an example.
Yearly middlePatterns that breakout in the middle third of the yearly price range do best.
ThrowbacksThrowbacks hurt post breakout performance.

Rounding Bottom: Examples

Rounding bottom chart pattern example

The above figure shows an example of a rounding bottom chart pattern. I selected this one to show you an example of what the bump looks like that sometimes appears near the midpoint of the turn. The bump begins at C and rises to A, which is taller than usual. Then price drops back to near the launch price, B, before resuming the rounding turn.

Rounding bottom chart pattern example in Encore Wire (WIRE)

This is another example, and a more recent one, of a rounding turn. The bump up begins near the middle of the rounding turn and ends near the same price at which it took off.

Rounding bottom chart pattern example in Steelcase (SCS)

This example shows Steelcase (SCS) on the daily scale. The chart is a bit compressed vertically, so the turn is not as rounded as it looks on my computer screen.

This chart is an excellent example of the mid-turn bump-up in price. I show that circled in green beginning from the launch price of A to B. Notice that B almost makes it back down to A before the uptrend resumes.
