Three Inside Up Candlestick Pattern - Definition, Formation, How to Trade

In candlestick analysis, confirmation is everything. A single candle can hint at a reversal. A two-candle pattern strengthens the case. But a three-candle pattern that builds sequentially, each candle reinforcing the message of the previous one, provides the kind of layered confirmation that gives traders genuine confidence to act. The Three Inside Up pattern is exactly this kind of formation. It does not just suggest that buyers are stepping in; it proves it across three consecutive sessions, each building on the last.

What is the Three Inside Up Candlestick Pattern?

The Three Inside Up is a three-candlestick bullish reversal pattern that appears at the bottom of a downtrend. It begins with a large bearish candle that continues the existing downtrend, followed by a smaller bullish candle that forms entirely within the range of the first candle (hence "inside"), and completed by a third bullish candle that closes above the high of the first bearish candle, confirming the reversal.

The pattern is essentially a Bullish Harami (the first two candles) confirmed by a third bullish candle, making it a stronger and more reliable reversal signal than the Harami alone.

Feature	Detail
Pattern type	Bullish reversal
Number of candles	Three
Appears at	Bottom of a downtrend or near a key support level
First candle	Large bearish candle continuing the downtrend
Second candle	Smaller bullish candle contained within the first candle's range
Third candle	Bullish candle closing above the first candle's high
Signal	Confirmed bullish reversal; buyers overcoming sellers across three sessions
Relationship to Harami	First two candles form a Bullish Harami; third candle confirms it

The Three Inside Up and the Bullish Harami Connection

Understanding the relationship between the Three Inside Up and the Bullish Harami is essential for grasping why the three-candle pattern is more powerful.

Feature	Bullish Harami	Three Inside Up
Number of candles	Two	Three
First candle	Large bearish	Large bearish
Second candle	Small bullish inside first	Small bullish inside first
Third candle	Not present	Bullish; closes above first candle's high
Confirmation level	Moderate; requires external confirmation	Strong; self-confirming within the pattern
Signal strength	Moderate	Strong
Action	Wait for confirmation before trading	Can trade at close of third candle with stop below first candle's low

The Three Inside Up takes the indecision hinted at by the Bullish Harami and resolves it definitively with the third candle. This self-contained confirmation makes it one of the most actionable three-candle reversal patterns.

How does the Three Inside Up Pattern form?

Each candle in the Three Inside Up tells a specific part of the reversal story.

Session	Candle	What Happens	Market Interpretation
Prior trend	Downtrend	Price has been falling consistently	Bears are in control; sellers dominant
Session 1	First candle (large bearish)	A large bearish candle forms, continuing the downtrend	Sellers still in control; downtrend persists
Session 2	Second candle (small bullish inside)	Price opens above the first candle's close; forms a small bullish candle contained within the first candle's range	First sign of buyer activity; selling momentum is slowing
Session 3	Third candle (confirming bullish)	Price opens higher; closes above the high of the first bearish candle	Buyers have decisively overpowered sellers; reversal confirmed

The three-session progression from seller dominance to indecision to buyer confirmation is what makes this pattern so reliable as a reversal signal.

Key Characteristics of a valid Three Inside Up Pattern

Criterion	Requirement
Prior downtrend	Pattern must appear after a clear and established downtrend
First candle	Must be a large bearish candle with a substantial real body
Second candle	Must be a bullish candle whose real body is fully contained within the first candle's real body
Second candle open	Must open above the first candle's close
Second candle close	Must close below the first candle's open
Third candle	Must be bullish and close above the high of the first bearish candle
Third candle confirmation	The higher the close of the third candle above the first candle's high, the stronger the signal
Volume	Increasing volume across the three sessions adds significant reliability

Identifying the Three Inside Up on a Chart

Follow these steps to correctly identify the pattern:

Step	Action
Step 1	Identify a clear downtrend preceding the pattern
Step 2	Locate a large bearish candle that continues the downtrend
Step 3	Check the next candle: it must be bullish and its entire real body must fall within the real body of the first candle
Step 4	Check the third candle: it must be bullish and close above the high of the first large bearish candle
Step 5	Assess the broader context: is the pattern near a support level, moving average, or Fibonacci zone?
Step 6	Check volume: is volume increasing across the three sessions?
Step 7	Confirm the prior trend is a downtrend, not a sideways consolidation

Factors That Increase Reliability

Factor	Why It Matters
Formation at a known support level	Aligns the reversal with an existing technical floor
Formation near a Fibonacci retracement	38.2%, 50%, or 61.8% levels add confluence
Formation at a long-term moving average	100-day or 200-day moving average acting as dynamic support
Increasing volume across three sessions	Volume progression from low to high confirms growing buyer participation
Third candle closes significantly above first candle's high	A strong close far above the first candle's high shows decisive bullish momentum
Large first candle	A larger first bearish candle means a more significant prior momentum shift is being reversed
Oversold RSI	RSI below 30 during pattern formation confirms price is stretched to the downside
Pattern after an extended downtrend	Longer the downtrend, more meaningful the reversal signal
MACD bullish crossover coinciding with pattern	Adds momentum confirmation to the price-based reversal signal

How to Trade the Three Inside Up Pattern

Entry Strategies

Approach	Entry Method	Risk Level
Standard entry	Enter long at the close of the third candle or at the open of the fourth session	Lowest risk; full pattern confirmed before entry
Aggressive entry	Enter long at the close of the second candle (Bullish Harami confirmed)	Higher risk; third candle confirmation not yet received
Breakout entry	Enter on a break above the third candle's high if there is hesitation at close	Moderate; waits for additional momentum confirmation

For most retail traders, entering at the open of the fourth session after all three candles have fully formed provides the safest entry with full pattern confirmation.

Stop Loss Placement

Method	Placement	Reasoning
Below the first candle's low	Most common and logical placement	If price falls below the first bearish candle's low, the reversal is clearly invalidated
Below the second candle's low	Tighter placement for aggressive entries	Pattern still intact if price stays above the second candle's low
Below the nearest support level	Broader placement for choppy markets	Accounts for normal volatility around the key support zone

Price Target Calculation

Method	How to calculate	Best For
Next resistance level	Identify the nearest overhead resistance above the entry	Conservative target; highest probability
Prior swing high	Target the high from where the downtrend originated	Full reversal scenario
Risk to reward projection	Target = Entry price + (2 to 3 times the risk per share)	Systematic traders
Fibonacci extension	Project upward Fibonacci extensions from the pattern low	Advanced traders using confluence
Height of first candle projected up	Measure first candle's range and add to the third candle's close	Measured move approach

Trade Example

Parameter	Value
Stock	A mid-cap NSE-listed stock
Prior trend	Downtrend from Rs 740 to Rs 530 over six weeks
First candle	Opens at Rs 548, closes at Rs 516 (large bearish candle)
Second candle	Opens at Rs 520, closes at Rs 534 (small bullish; inside first candle's body)
Third candle	Opens at Rs 536, closes at Rs 558 (bullish; closes above first candle's open of Rs 548)
Entry price	Rs 560 (open of fourth session)
Stop loss	Rs 512 (below first candle's low)
Risk per share	Rs 560 - Rs 512 = Rs 48
First target (resistance)	Rs 608
Second target (prior swing high)	Rs 680
Reward to first target	Rs 608 - Rs 560 = Rs 48
Risk to reward (first target)	1 : 1 (minimum acceptable)
Reward to second target	Rs 680 - Rs 560 = Rs 120
Risk to reward (second target)	1 : 2.5
Action	Enter full position; book 50% at first target; trail stop on remainder

Volume Behaviour in the Three Inside Up

Session	Ideal Volume	What It Signals
First candle (large bearish)	Above average	Continued selling pressure; bears still active
Second candle (small bullish)	Below average or moderate	Selling momentum slowing; buyers cautiously entering
Third candle (confirming bullish)	Highest of the three	Buyers are now fully in control; institutional conviction

Volume Warning Signs	Implication
Declining volume on the third candle	Weak confirmation; buyers may lack conviction
Very high volume on second candle with bearish close	Potential false reversal; sellers may still be dominant
All three candles on below-average volume	Low-conviction pattern; wait for additional confirmation

Common Mistakes When Trading the Three Inside Up

Mistake	Why It Is Problematic
Trading the pattern without a prior downtrend	Without a downtrend, the pattern has no reversal context
Acting on the first two candles alone (Bullish Harami)	The Harami alone is a weaker signal; the third candle is critical
Third candle does not close above first candle's high	This disqualifies the Three Inside Up; do not trade an incomplete pattern
Ignoring the broader market trend	A bullish reversal pattern in a stock during a broader market selloff has lower reliability
Using only on intraday charts	The pattern is significantly less reliable on short timeframes
Placing stop loss too tight	Normal price oscillation can trigger stops placed too close to the entry
Ignoring volume	Low-volume patterns especially on the third candle are less reliable
Overlooking the second candle containment criterion	If the second candle's body is not fully inside the first, it is not a valid Three Inside Up

Three Inside Up in Indian Markets: Practical Context

Market Scenario	Where the Pattern Appears
Post-earnings selloff recovery	Quality stocks overreacting to a quarterly miss form the pattern as buyers recognise value
Sector-specific correction bottom	Banking, IT, or pharma stocks forming the pattern after a sharp sector rotation out
Broader market correction bottom	Nifty 50 or individual index heavyweights forming the pattern at a major support level during a market correction
FII selling absorption	Domestic institutional investors absorbing FII supply can create this pattern over three sessions
Post-global event recovery	Indian markets recovering from a global shock (US Fed surprise, geopolitical event) can form this pattern

Tools commonly combined with this pattern in Indian markets:

Tool	How It Adds Confluence
RSI below 30 on first candle day	Confirms oversold conditions; increases reversal probability
200-day moving average as support	Pattern forming at the 200 DMA is one of the strongest reversal setups
Delivery volume data (NSE)	Rising delivery percentage across the three sessions confirms genuine buying interest
Put-Call Ratio (PCR)	Extreme PCR readings combined with this pattern signal a more significant reversal
FII and DII activity	DII buying increasing across the three sessions alongside the pattern adds institutional confirmation
