The rounding bottom, also known as a saucer bottom, is a long-term bullish reversal pattern that signals a gradual shift from selling pressure to buying pressure. This pattern takes time to form but often leads to significant upside moves when it completes. Understanding how to identify and trade it can help you catch major trend reversals.
What is a Rounding Bottom Pattern?
The rounding bottom is a reversal pattern that forms after a downtrend:
- Shape: Resembles the bottom of a bowl or saucer
- Duration: Typically takes weeks to months to form
- Neckline: Horizontal resistance level at the pattern's peaks
- Breakout: Price closes above the neckline to confirm the pattern
Key concept: The rounding bottom represents a gradual transition from bearish to bullish sentiment. Unlike sharp reversals, this pattern shows steady accumulation as sellers slowly exit and buyers quietly accumulate. The gradual nature often leads to sustainable uptrends.
Pattern Identification Rules
Look for these characteristics when identifying a rounding bottom:
1. Prior Downtrend
- Price must be in a clear downtrend before the pattern forms
- The decline should be significant (at least 15-20%)
- Selling momentum should gradually decrease
2. Left Side of the Saucer
- Price declines at a decreasing rate
- Volume typically decreases as selling pressure fades
- Candles get smaller as momentum slows
3. Bottom of the Saucer
- Price moves sideways with small price ranges
- Volume reaches its lowest point
- This phase can last several weeks
4. Right Side of the Saucer
- Price begins rising at an increasing rate
- Volume gradually increases
- Buying pressure becomes evident
Rounding Bottom Example
Stock XYZ declines from $80 to $50 over three months as selling pressure fades.
Price bottoms around $50-52 for six weeks with low volume and small candles.
Price gradually rises back toward $65 over two months on increasing volume.
Neckline at $65 (previous resistance). Breakout above $65 confirms the pattern.
Target: $80 (the depth of $15 added to the neckline of $65).
Trading the Rounding Bottom
Entry Strategies
- Breakout entry: Buy when price closes above the neckline
- Pullback entry: Buy on a retest of the neckline as support
- Early entry: Buy during the right side formation with tight stops
Stop Loss Placement
- Conservative: Below the bottom of the saucer
- Moderate: Below the most recent swing low
- Aggressive: Below the neckline (after breakout)
Profit Targets
- Measured move: Add the pattern depth to the neckline
- Example: If depth is $15 and neckline is $65, target is $80
- Consider taking partial profits at 50% of the target
- Use trailing stops to capture extended moves
Volume Analysis
Volume patterns are critical for rounding bottom confirmation:
- Left side: Decreasing volume as selling exhausts
- Bottom: Very low volume indicating indifference
- Right side: Increasing volume as buyers accumulate
- Breakout: Volume spike confirms genuine buying interest
Rounding Bottom vs Cup and Handle
These patterns are related but have key differences:
- Rounding bottom: Pure saucer shape, breakout directly after right side
- Cup and handle: Saucer shape plus a small handle consolidation
- Cup and handle is generally more reliable due to the handle confirmation
- Both are bullish reversal patterns with similar targets
Timeframe Considerations
The rounding bottom appears on various timeframes:
- Weekly charts: Major reversals, multi-month holding periods
- Daily charts: Swing trade setups, weeks to months
- 4-hour charts: Shorter-term reversals, days to weeks
- Longer timeframes typically produce more reliable signals
Common Mistakes to Avoid
- Entering too early: Wait for breakout confirmation
- Ignoring volume: Pattern needs proper volume signature
- Wrong pattern depth: Saucer should be gradual, not V-shaped
- Resistance overhead: Check for major resistance above neckline
- Impatience: This pattern takes time to develop fully
Pattern Failure Signs
Watch for these warning signs of potential failure:
- Price breaks below the bottom of the saucer
- Volume increases on the left side (continued distribution)
- Multiple failed attempts to break the neckline
- Right side rises too steeply (unsustainable)
- Breakout occurs on low volume
Best Market Conditions
The rounding bottom works best when:
- Overall market is stabilizing after a decline
- Sector rotation is occurring
- Company fundamentals are improving
- Interest rates are stable or declining
- Economic indicators are bottoming
Combining with Other Analysis
Strengthen your rounding bottom trades with:
- Fundamental analysis: Improving earnings or revenue
- Sector analysis: Sector showing relative strength
- Moving averages: Price crossing above 50 and 200-day MAs
- RSI: Rising from oversold, crossing above 50

Summary
The rounding bottom is a reliable long-term bullish reversal pattern that forms when a downtrend gradually transitions to an uptrend. Look for the characteristic saucer shape with decreasing volume on the left, low volume at the bottom, and increasing volume on the right. Enter on the neckline breakout with stops below recent lows. The measured move target equals the pattern depth added to the neckline. Patience is required as this pattern takes weeks to months to complete.
