What is Candlesticks? - Definition, Types, Advantages & Popular Candlestick Charts

Before a trader can read a chart, they must understand the language the chart is written in. In technical analysis, that language is candlesticks. Every price movement, every battle between buyers and sellers, every moment of momentum or indecision is captured within the structure of a single candlestick. Learning to read candlesticks is not just a charting skill. It is the foundation of understanding market psychology through price action.

What is a Candlestick?

A candlestick is a type of price chart element that displays the open, high, low, and close prices for a specific time period in a single visual unit. Each candlestick represents the complete price story of that period, whether it is one minute, one hour, one day, or one week, compressing four critical data points into one intuitive shape.

The candlestick chart was developed in Japan in the eighteenth century by a rice trader named Munehisa Homma, who used it to track rice futures prices. It was introduced to the Western world by Steve Nison in his 1991 book "Japanese Candlestick Charting Techniques" and has since become the dominant charting method used by traders worldwide.

Structure of a Candlestick

Every candlestick has two main components: the real body and the shadows (also called wicks).

1. The Real Body

The real body is the rectangular section of the candlestick that represents the range between the opening price and the closing price of the session.

Body Colour	What It Means
Green or White (bullish body)	Closing price is higher than the opening price; buyers won the session
Red or Black (bearish body)	Closing price is lower than the opening price; sellers won the session

Body Size	What It Means
Long body	Strong momentum in the direction of the close; decisive winner between buyers and sellers
Short body	Low momentum; close is near the open; indecision or consolidation
No body (open equals close)	Complete equilibrium; forms a Doji

2. The Shadows (Wicks)

The shadows are the thin lines extending above and below the real body. They represent the highest and lowest prices reached during the session.

Shadow	What It Represents
Upper shadow	The highest price reached during the session above the real body
Lower shadow	The lowest price reached during the session below the real body

Shadow Length	What It Implies
Long upper shadow	Buyers pushed price significantly higher but sellers pushed it back down; bearish pressure at highs
Long lower shadow	Sellers pushed price significantly lower but buyers pushed it back up; bullish support at lows
No upper shadow	Price never moved above the close (bullish) or above the open (bearish); strong directional momentum
No lower shadow	Price never moved below the open (bullish) or below the close (bearish); strong directional momentum

Complete Candlestick Anatomy

Component	Price Point	Visual Location
Top of upper shadow	Session high	Topmost point of the candlestick
Top of real body	Higher of open or close	Top edge of the rectangular body
Bottom of real body	Lower of open or close	Bottom edge of the rectangular body
Bottom of lower shadow	Session low	Bottommost point of the candlestick

Candlestick Charts vs Bar Charts vs Line Charts

Candlestick charts are one of three primary chart types used in technical analysis. Understanding the differences clarifies why candlesticks have become the dominant choice.

Feature	Candlestick Chart	Bar Chart	Line Chart
Data displayed	Open, High, Low, Close	Open, High, Low, Close	Close price only
Visual intuitiveness	Very high; colour and shape immediately convey direction	Moderate; requires interpretation of tick marks	Low; minimal information per data point
Buyer/seller dynamics	Immediately visible through body colour and shadow length	Visible but less intuitively	Not visible
Pattern recognition	Excellent; rich library of single and multi-candle patterns	Good; some patterns visible	Limited
Complexity	Moderate	Moderate	Very low
Best for	Active trading; pattern analysis; market psychology	Systematic traders familiar with OHLC format	Long-term trend overview; non-traders

Types of Candlesticks

Candlesticks can be broadly categorised by the size of their bodies and shadows. Each type communicates a different message about buyer and seller activity.

Category 1: Strong Momentum Candles

These candles have large real bodies and minimal or no shadows, indicating decisive dominance by either buyers or sellers.

Candlestick Type	Description	Signal
Bullish Marubozu	Long green body; no upper or lower shadow; open equals low, close equals high	Complete buyer dominance throughout the session
Bearish Marubozu	Long red body; no upper or lower shadow; open equals high, close equals low	Complete seller dominance throughout the session
Long Bullish Candle	Long green body with small shadows	Strong buying momentum; buyers clearly in control
Long Bearish Candle	Long red body with small shadows	Strong selling momentum; sellers clearly in control

Category 2: Indecision Candles

These candles have small or non-existent real bodies with longer shadows, indicating uncertainty and a balance of power between buyers and sellers.

Candlestick Type	Description	Signal
Doji	Virtually no real body; open and close at the same price	Complete indecision; trend reversal warning
Long Legged Doji	No real body; very long upper and lower shadows	Extreme indecision; significant two-sided volatility
Spinning Top	Small real body; upper and lower shadows longer than body	Moderate indecision; neither side dominant
High Wave Candle	Very small body; extremely long shadows on both sides	Extreme uncertainty; strong reversal warning

Category 3: Reversal Signal Candles

These single candlesticks have specific body and shadow configurations that indicate potential trend reversals.

Candlestick Type	Body	Shadow	Signal
Hammer	Small; at top of candle	Long lower; no upper	Bullish reversal at bottom of downtrend
Inverted Hammer	Small; at bottom of candle	Long upper; no lower	Potential bullish reversal at bottom of downtrend
Shooting Star	Small; at bottom of candle	Long upper; no lower	Bearish reversal at top of uptrend
Hanging Man	Small; at top of candle	Long lower; no upper	Bearish reversal at top of uptrend
Gravestone Doji	No body; at bottom	Long upper; no lower	Bearish reversal
Dragonfly Doji	No body; at top	No upper; long lower	Bullish reversal

Category 4: Continuation Candles

These candles signal that the existing trend is likely to continue rather than reverse.

Candlestick Type	Description	Signal
Long bullish candle in uptrend	Large green candle continuing an uptrend	Trend continuation; buyers adding to positions
Long bearish candle in downtrend	Large red candle continuing a downtrend	Trend continuation; sellers adding to positions
Bullish gap-up candle	Candle opens above previous close	Strong bullish momentum; continuation
Bearish gap-down candle	Candle opens below previous close	Strong bearish momentum; continuation

How to Read a Candlestick Chart: Step by Step

Step	Action
Step 1	Identify the time period of each candle (1-day, 1-week, etc.)
Step 2	Note the colour of the body: green means buyers won; red means sellers won
Step 3	Assess the body size: large body means strong momentum; small body means indecision
Step 4	Examine the upper shadow: long upper shadow means sellers pushed back from the high
Step 5	Examine the lower shadow: long lower shadow means buyers pushed back from the low
Step 6	Look at the pattern context: what is the prevailing trend before this candle?
Step 7	Identify if the candle forms a recognisable single or multi-candle pattern
Step 8	Wait for confirmation: single candles rarely justify a trade without context
Step 9	Combine with other tools: support/resistance, volume, RSI, moving averages
Step 10	Manage risk: always define stop loss before entering any trade based on a candle signal

Candlestick Timeframes and Their Significance

Timeframe	What Each Candle Represents	Best For
1-minute	One minute of price action	Scalpers; very short-term traders
5-minute	Five minutes of price action	Active intraday traders
15-minute	Fifteen minutes of price action	Intraday swing traders
1-hour	One hour of price action	Short-term swing traders
Daily	One full trading session	Most popular; swing and positional traders
Weekly	One full trading week	Longer-term position traders
Monthly	One full calendar month	Long-term investors; macro trend analysis

The daily chart is the most widely used timeframe for candlestick pattern analysis. Patterns on daily charts reflect meaningful shifts in sentiment across large numbers of market participants and produce more reliable signals than intraday patterns.

Common Mistakes When Using Candlestick Analysis

Mistake	Why It Is Problematic
Trading single candles without context	A Hammer in the middle of a trend has no reversal meaning; context is everything
Ignoring the trend before the pattern	Reversal patterns only work when there is a trend to reverse
Acting without confirmation	Most patterns require at least one confirming candle before entering
Ignoring volume	A pattern on low volume carries far less significance than one on high volume
Using candlesticks in isolation	Must be combined with support/resistance, trend analysis, and other indicators
Memorising patterns without understanding psychology	Pattern names without understanding the buyer/seller story behind them leads to mechanical misapplication
Treating all timeframes equally	A Doji on a 1-minute chart is far less significant than a Doji on a weekly chart
Overtrading based on every pattern	Not every candlestick pattern is a tradeable signal; selectivity and context are critical
