Overview
Bullish Concealing Baby Swallow
Kotsubame Tsutsumi
Also known as: Hidden Baby Swallow, Four Marubozu Reversal
The Bullish Concealing Baby Swallow is an extremely rare four-candle reversal pattern consisting of bearish marubozus where the third candle's upper shadow (the baby) is concealed by the fourth candle, signaling exhaustion of the downtrend.
This is one of the rarest patterns in Japanese candlestick analysis. It requires four specific candles: two bearish marubozus establishing strong selling momentum, followed by a third candle that gaps down but shows a long upper shadow reaching into the previous body (the swallow trying to fly up), and a fourth candle that engulfs the third candle entirely, concealing the upper shadow. Despite all four candles being bearish, the pattern is bullish because the third candle's upper shadow reveals buying interest emerging, and the fourth candle's wide range shows the final exhaustion of sellers. The concealment of the baby (third candle) by the fourth represents the last gasp of bearish momentum before reversal.
History & Etymology
The Concealing Baby Swallow originates from classical Japanese candlestick literature. It is one of the patterns that Steve Nison brought to Western attention, though he noted its extreme rarity. The pattern was used by Japanese rice traders as a signal that aggressive selling was about to exhaust itself.
The baby swallow refers to the third candle with its long upper shadow, like a baby bird trying to take flight (the shadow reaching upward). The fourth candle conceals this baby by engulfing it entirely. The metaphor suggests the last sign of hope (the swallow) is hidden before the actual reversal.
How It Forms
Formation Steps
- 1First candle: bearish marubozu (no shadows) continuing the downtrend
- 2Second candle: bearish marubozu opening within the first candle body
- 3Third candle: bearish candle opening at or near the low of the second, with a long upper shadow that enters the second candle body
- 4Fourth candle: bearish candle that completely engulfs the third candle including its upper shadow
Prerequisites
- Established downtrend
- First two candles must be marubozu-type (no or minimal shadows)
- Third candle must have a notable upper shadow
Confirmation Signals
- Bullish candle following the pattern
- Volume increase on the following bullish session
- Price closes above the fourth candle high
Invalidation Signals
- Continued bearish candles after the pattern
- No bullish follow-through within 2-3 sessions
- Price makes new lows below the pattern
Candle Breakdown
First Marubozu
A bearish marubozu with no shadows, showing pure selling control.
Sellers completely dominate. No buyer resistance at any point during the session.
Second Marubozu
Another bearish marubozu opening within the first candle body.
Selling continues unabated. Two consecutive marubozus indicate extreme bearish momentum.
Baby Swallow
A bearish candle opening near the second candle low with a long upper shadow entering the second candle body.
The long upper shadow is the first sign of buyer resistance. Buyers pushed price up significantly before sellers regained control.
Concealing Candle
A bearish candle that engulfs the third candle entirely, including its upper shadow.
The final exhaustion candle. Despite concealing the baby, this wide-range candle with a lower shadow shows selling is reaching a climax.
Psychology
Four bearish candles seem overwhelmingly negative, but the subtle clue is in the third candle's upper shadow showing emerging buying interest, and the fourth candle's exhaustion characteristics. The pattern captures the very end of a selling frenzy.
Buyer Perspective
Buyers are timid but beginning to test the waters. The third candle upper shadow shows their first attempt. After the fourth candle exhausts sellers, buyers can step in with more confidence.
Seller Perspective
Sellers are fully committed through the first three candles. By the fourth candle, they are throwing everything at the market in a final push, but their ammunition is running out.
Smart Money Action
Institutions begin testing buy levels during the third candle (creating the upper shadow) and accumulate during the fourth candle wide range, absorbing the final wave of panic selling.
Retail Trader Trap
Retail traders see four bearish candles and assume the downtrend will continue indefinitely. They sell or short at the worst possible time.
Emotional Cycle
Trading Strategy
Aggressive Entry
Enter long at the close of the fourth candle or on the open of the fifth session.
Conservative Entry
Wait for a bullish candle to close above the fourth candle high before entering.
At the open of the first marubozu (reclaiming the pattern start).
At the swing high that preceded the downtrend.
Measured move equal to the pattern range projected upward.

Risk Management
Volume Analysis
Volume Confirmation
Ideally volume decreases on candles 3-4 relative to candles 1-2, showing selling exhaustion. Volume should spike on the confirmation candle.
Volume Profile
Declining volume on the later candles confirms the exhaustion thesis.
Volume Divergence
If volume increases on candle 4, it may be genuine selling rather than exhaustion. Require bullish confirmation.
Technical Confluence
Support Resistance
Most reliable when the pattern forms at a clear support level.
Fibonacci Levels
Pattern at a 78.6% retracement of the prior upswing adds confluence.
Moving Averages
Pattern near the 200 SMA adds significance.
Rsi Confirmation
RSI below 20 during the pattern is ideal.
Macd Confirmation
MACD showing diminishing negative histogram bars during candles 3-4.
Bollinger Bands
Pattern piercing the lower band with candle 4 shows overextension.
Vwap
Not particularly relevant for this multi-day pattern.
Ichimoku Cloud
Pattern below the cloud, reversal begins recovery toward the cloud.
Elliott Wave
May mark the end of Wave 5 in an impulse decline.
Wyckoff Phase
Can appear as part of the selling climax phase.
Market Profile
The pattern creates a long selling tail that gets rejected.
Order Flow
Look for delta turning positive during the third candle upper shadow.
Open Interest
Declining open interest during candles 3-4 suggests short covering beginning.
Multi-Timeframe Analysis
Higher Timeframe Alignment
A daily pattern at weekly support maximizes reliability.
Lower Timeframe Entry
Use 4-hour chart to spot the reversal forming within the fourth candle session.
Timeframe Confluence
Best when daily exhaustion aligns with weekly oversold conditions.
Top-Down Approach
Weekly support, daily identifies pattern, 4-hour confirms entry.
Statistics
Historical Examples
Energy Sector Exhaustion
successThe Energy Select Sector ETF formed a pattern resembling a concealing baby swallow during the March 2020 crash. Four consecutive bearish candles with the characteristics of the pattern preceded a strong reversal.
Lesson: Even in extreme market conditions, the exhaustion signals within the pattern (diminishing momentum, upper shadows) provide clues about the coming reversal.
Variations
Near-Marubozu Variant
The first two candles have very small shadows rather than being perfect marubozus.
Confusion Matrix
Patterns commonly confused with Bullish Concealing Baby Swallow and how to distinguish them.
Bullish Three Stars South
4500% similarCount the candles and check for marubozu requirements. The Concealing Baby Swallow specifically requires two initial marubozus.
Key Differences
- Three Stars in the South has three candles with diminishing bodies
- Concealing Baby Swallow has four candles with specific marubozu requirements
The Bullish Engulfing is one of the most popular and reliable two-candle reversal patterns. A large bullish candle completely engulfs the prior bearish candle body, signaling a decisive shift from selling to buying control.
The Ladder Bottom is a five-candle bullish reversal pattern where three descending bearish candles are followed by an exhaustion signal and a confirming bullish candle, resembling climbing down and then back up a ladder.
The Morning Star is a three-candle bullish reversal pattern consisting of a large bearish candle, a small star candle showing indecision, and a large bullish candle confirming the reversal. It is one of the most widely recognized and reliable bottom reversal signals.
The Bullish Three Inside Up is a three-candle reversal pattern that combines a bullish harami with a confirming third candle that closes above the first candle's open, providing a more reliable reversal signal than the harami alone.
Three Stars in the South is a rare bullish reversal pattern of three progressively smaller bearish candles, each with shorter lower shadows and higher lows, signaling that selling pressure is systematically diminishing.
The Bearish Breakaway is a five-candle reversal pattern where a gap-up rally stalls over three sessions before a powerful bearish candle breaks back down into the gap, signaling the uptrend is exhausted.
Pro Tips & Common Mistakes
Pro Tips
- This is one of the rarest patterns in candlestick analysis so do not force its identification
- The two initial marubozus are the strict requirement that makes this pattern uncommon
- Always require bullish confirmation after the pattern since all four candles are bearish
- The third candle upper shadow is the key tell of emerging buying interest
Common Mistakes
- Identifying this pattern when the first two candles are not true marubozus
- Trading without confirmation since all four candles are bearish
- Confusing this with any sequence of four bearish candles
- Not understanding that this is a reversal pattern despite all bearish candles
Advanced Techniques
- Use the pattern as a watchlist trigger rather than a direct entry signal
- Combine with market breadth analysis to confirm sector-wide exhaustion
- Monitor dark pool activity during the third and fourth candles for institutional accumulation
Institutional Perspective
The concealing baby swallow is so rare that few institutions code for it specifically. However, the underlying principle (exhaustion after consecutive marubozus) is well understood by institutional quant teams who monitor candle body ratios.
Fun Facts
- The Concealing Baby Swallow is so rare that many candlestick pattern recognition software programs do not even include it in their scanning algorithms.
- The swallow metaphor in Japanese culture represents hope and the return of spring, fitting for a bullish reversal pattern.
Frequently Asked Questions
It is one of the rarest patterns in candlestick analysis. The requirement for two consecutive marubozus followed by the specific third and fourth candle structure makes it extraordinarily uncommon. Many experienced traders have never seen a textbook example in real-time.
The pattern captures exhaustion. While all four candles are bearish, the subtle clues (diminishing momentum, the third candle upper shadow showing emerging buying, the fourth candle wide range showing final exhaustion) collectively signal that selling is about to end. The bullish move comes AFTER the pattern.
