Anatomy of a candlestick
A candlestick represents a single period of trading — one minute, one hour, one day, one week. It shows four pieces of data in one visual:
Open
The price at the start of the period
Close
The price at the end of the period
High
The highest price reached during the period
Low
The lowest price reached during the period
The thick rectangular body spans from open to close. The thin lines above and below are called wicks (or shadows) and represent the high and low. If the close is above the open, the candle is green (or white) — buyers won the session. If the close is below the open, the candle is red (or black) — sellers won.
Reading a candle at a glance
Green candle
- Close > Open → buyers won
- Long body = strong buying
- Long lower wick = sellers tried, buyers recovered
- Long upper wick = buyers tired at the high
Red candle
- Close < Open → sellers won
- Long body = strong selling
- Long upper wick = buyers tried, sellers recovered
- Long lower wick = sellers tired at the low
How to read candles
The key insight is that every candle tells you about the balance of power between buyers and sellers in that period. A few principles to internalize:
Long body, short wicks
One side dominated completely. Strong trend continuation likely.
Short body, long wicks
Both sides fought hard but neither won decisively. Indecision — watch for a breakout.
Gap up/down from previous close
Strong emotion overnight. The market opened with committed buyers or sellers before a single trade.
Wicks matter as much as the body
A long lower wick on a red candle still shows buyers stepped in. It is not purely bearish.
Volume amplifies everything
A pattern on high volume carries far more weight than the same pattern on thin trading.
8 key candlestick patterns explained
Sorted by signal type. Each pattern includes what to look for and what it signals.
Hammer
Small body near the top of the range, long lower wick (at least 2× the body), little or no upper wick. Sellers pushed price down hard during the session, but buyers fought back and closed near the open.
Signal
Potential bullish reversal — most powerful at the bottom of a downtrend or at key support.
Shooting Star
Small body near the bottom of the range, long upper wick. The mirror image of a hammer. Buyers drove price up sharply, but sellers took control and closed the session near the open.
Signal
Potential bearish reversal — most powerful at the top of an uptrend or at key resistance.
Doji
Open and close at virtually the same price, creating a cross or plus-sign shape. Neither buyers nor sellers won the session — perfect indecision.
Signal
Indecision — in an uptrend, signals possible exhaustion. In a downtrend, signals a possible floor. Needs confirmation from the next candle.
Bullish Engulfing
A small red (down) candle followed by a large green (up) candle whose body completely engulfs the previous day's body. Buyers overwhelmed sellers in one decisive session.
Signal
Strong bullish reversal signal — even stronger when accompanied by higher-than-average volume.
Bearish Engulfing
A small green (up) candle followed by a large red (down) candle that completely engulfs the previous day's body. Sellers took control decisively.
Signal
Strong bearish reversal signal — confirms the end of an uptrend or rejection at resistance.
Morning Star
A large red candle → a small indecisive candle (often a doji, gapping lower) → a large green candle closing above the midpoint of the first candle. A three-act story: sellers dominate, confusion, then buyers take over.
Signal
High-confidence bullish reversal, especially after an extended downtrend. One of the most reliable 3-candle patterns.
Evening Star
The mirror of the Morning Star: a large green candle → a small indecisive candle → a large red candle closing below the midpoint of the first candle.
Signal
High-confidence bearish reversal at the top of an uptrend. Look for this at resistance levels.
Three White Soldiers
Three consecutive large green candles, each opening within the prior body and closing near its high. Sustained, orderly buying pressure with no hesitation.
Signal
Strong bullish continuation or reversal. Signals genuine buying conviction — not just a short squeeze.
Context makes patterns work
A hammer in the middle of a trading range means very little. The same hammer at a tested support level after a sustained downtrend, accompanied by high volume and confirmed by a green close the next day — that is a meaningful signal. Context is everything in technical analysis.
Location on the chart
Patterns at support, resistance, or key moving averages (50-day, 200-day) carry far more weight than patterns in open space. A bullish reversal pattern at a price level that held 3 times in the past is actionable. The same pattern in the middle of a choppy range is noise.
Prior trend
Reversal patterns only make sense after there is something to reverse. A hammer needs a downtrend to reverse. An evening star at the bottom of a downtrend makes no sense — there is nothing to sell into.
Volume confirmation
A bullish engulfing on volume 3× the 20-day average is a very different signal from one on thin, below-average volume. Higher volume means more participants committed to the move.
Confirmation candle
Never trade a reversal pattern on the candle that forms it — wait for the next candle to confirm. If a morning star appears, wait for the next session to close green before acting. This simple rule eliminates many false signals.
The bottom line
Candlestick patterns are a language for reading short-term market psychology — not a crystal ball. Combine them with a clear understanding of the trend, key price levels, and volume, and they become a genuinely useful tool. Used in isolation, they will mislead you. Used in context, they sharpen your timing and help you see when buyers or sellers are losing conviction before everyone else does.

Frequently asked questions
Are candlestick patterns reliable?+
On their own, no single candlestick pattern is highly reliable — they describe price action in one or two sessions and provide context, not certainty. They become much more useful when they appear at meaningful levels (support, resistance, moving averages) and are confirmed by the next session closing in the expected direction. Think of them as one input among several, not a standalone signal.
What timeframe are candlestick patterns most reliable on?+
Longer timeframes produce more reliable signals because each candle represents more trading activity and smoother out noise. Daily charts are the standard for most traders. Patterns on weekly charts carry more weight than daily, and daily more than hourly. On 1-minute charts, patterns are almost meaningless noise.
What is the most reliable candlestick pattern?+
The Engulfing pattern (both bullish and bearish) has among the best track records in backtesting when it appears at clear support or resistance levels with above-average volume. The Three White Soldiers and Three Black Crows are also considered high-conviction patterns, though they're less common.
What is the difference between a doji and a spinning top?+
A doji has a near-zero body — the open and close are at nearly the same price. A spinning top has a small but visible body, with upper and lower wicks. Both signal indecision, but a doji is a more extreme version. In context, both carry similar meaning: momentum is stalling and a reversal is possible.
Do candlestick patterns work for crypto and ETFs?+
Yes. Candlestick patterns are a universal tool that applies to any market that trades via an exchange: stocks, ETFs, forex, commodities, and crypto. The underlying psychology (fear, greed, uncertainty) is the same regardless of the asset.
