What Is a Candlestick Chart?
Candlestick charts are the most widely used chart type in trading. Originating in 18th-century Japan where rice traders used them to track market prices, candlesticks display four critical pieces of price information in a single visual element: the Open, High, Low, and Close (OHLC) for a given time period.
Every candlestick tells a story about the battle between buyers and sellers during that period. Learning to read these stories is one of the most valuable skills you can develop as a trader.
Imagine each candlestick is a summary of a boxing round. The body (the thick part) tells you who won the round — green means the buyers won (price went up), red means the sellers won (price went down). The wicks (thin lines) show how far each fighter swung — a long upper wick means buyers threw a big punch that got blocked and pushed back. A long lower wick means sellers attacked hard but buyers fought back. A tiny body with long wicks? That round was a draw — nobody could take control. Read enough rounds and you start predicting who's going to win the fight.
Anatomy of a Candlestick
Each candlestick has two main components:
The Body
The body is the thick, colored portion of the candlestick. It represents the range between the opening and closing prices:
- Bullish candle (green/white): The close is higher than the open. Buyers dominated during this period. The bottom of the body is the open and the top is the close.
- Bearish candle (red/black): The close is lower than the open. Sellers dominated during this period. The top of the body is the open and the bottom is the close.
A large body indicates strong buying or selling pressure. A small body indicates indecision or low activity.
The Wicks (Shadows)
The thin lines extending above and below the body are called wicks or shadows:
- Upper wick: Extends from the top of the body to the highest price reached during the period. A long upper wick means buyers pushed the price up but sellers forced it back down.
- Lower wick: Extends from the bottom of the body to the lowest price reached during the period. A long lower wick means sellers pushed the price down but buyers forced it back up.
The length and position of the wicks reveal information about market sentiment that the body alone cannot show. Long wicks indicate rejection of a price level — the market tested it and pulled back.
| Component | Bullish Candle | Bearish Candle |
|---|---|---|
| Top of body | Close price | Open price |
| Bottom of body | Open price | Close price |
| Upper wick tip | Period high | Period high |
| Lower wick tip | Period low | Period low |
Common Single-Candle Patterns
Single-candle patterns provide quick clues about potential market direction. Here are the most important ones to learn:
Doji
A doji forms when the open and close prices are virtually equal, creating a very small or nonexistent body with wicks on either side. It signals indecision — neither buyers nor sellers won the battle. A doji after a strong trend can signal a potential reversal.
Variations include the dragonfly doji (long lower wick, no upper wick — bullish signal at support) and the gravestone doji (long upper wick, no lower wick — bearish signal at resistance).
Hammer
The hammer has a small body at the top with a long lower wick (at least twice the body length) and little or no upper wick. It appears at the bottom of a downtrend and signals potential bullish reversal. The long lower wick shows that sellers pushed the price down aggressively, but buyers stepped in and pushed it back up before the close.
Shooting Star
The shooting star is the bearish counterpart to the hammer. It has a small body at the bottom with a long upper wick and little or no lower wick. It appears at the top of an uptrend and signals potential bearish reversal. Buyers pushed the price up, but sellers overwhelmed them and drove the price back down by the close.
Engulfing Candles
A bullish engulfing pattern occurs when a small bearish candle is followed by a larger bullish candle whose body completely engulfs the previous candle's body. This signals strong buying momentum and a potential reversal from bearish to bullish.
A bearish engulfing is the opposite — a small bullish candle followed by a larger bearish candle that engulfs it. This signals selling momentum and a potential reversal from bullish to bearish.
Pin Bar
A pin bar is characterized by a very long wick on one side (at least two-thirds of the total candle range) and a tiny body on the opposite end. A pin bar with a long lower wick at a support level is bullish. A pin bar with a long upper wick at a resistance level is bearish. Pin bars are among the most reliable single-candle reversal signals when they appear at key price levels.
Common Multi-Candle Patterns
Multi-candle patterns provide stronger signals because they incorporate more price data:
Morning Star (Bullish Reversal)
This three-candle pattern appears at the bottom of a downtrend:
- A large bearish candle (sellers in control)
- A small-bodied candle that gaps down (indecision — can be a doji)
- A large bullish candle that closes well into the first candle's body (buyers take over)
The morning star signals that selling pressure is exhausted and buyers are stepping in aggressively.
Evening Star (Bearish Reversal)
The bearish counterpart to the morning star, appearing at the top of an uptrend:
- A large bullish candle (buyers in control)
- A small-bodied candle that gaps up (indecision)
- A large bearish candle that closes well into the first candle's body (sellers take over)
Three White Soldiers (Bullish Continuation)
Three consecutive bullish candles, each opening within the previous candle's body and closing higher. Each candle should have a decent-sized body with small upper wicks. This pattern indicates sustained, strong buying pressure and typically signals the start or continuation of an uptrend.
Three Black Crows (Bearish Continuation)
The bearish counterpart — three consecutive bearish candles, each opening within the previous candle's body and closing lower. Each candle has a solid body with small lower wicks. This indicates sustained selling pressure and often signals further downside.
Understanding Timeframes
The same currency pair can look completely different depending on the timeframe you choose. Each candlestick represents one unit of the selected timeframe:
| Timeframe | Each Candle Represents | Best For |
|---|---|---|
| M1 (1 minute) | 1 minute of price action | Scalping (very noisy) |
| M5 (5 minutes) | 5 minutes of price action | Short-term scalping |
| M15 (15 minutes) | 15 minutes of price action | Intraday trading |
| H1 (1 hour) | 1 hour of price action | Day trading |
| H4 (4 hours) | 4 hours of price action | Swing trading |
| D1 (daily) | One full trading day | Swing and position trading |
| W1 (weekly) | One full trading week | Long-term analysis |
Higher timeframes produce more reliable signals. A hammer on the daily chart is far more significant than a hammer on the 5-minute chart. As a general rule, use higher timeframes (H4 and above) for identifying the trend and key levels, and lower timeframes (H1 and below) for timing entries.
Best practice for beginners: Start your analysis on the daily chart to identify the overall trend and major support/resistance levels. Then drop down to the H4 or H1 chart to look for candlestick patterns at those levels for trade entries.
Using Candlesticks with Support and Resistance
Candlestick patterns are most powerful when they form at key support and resistance levels. A hammer that forms in the middle of a range is far less meaningful than a hammer that forms precisely at a well-established support level.
Here is how to combine them:
- Identify support and resistance levels on a higher timeframe (daily or H4). These are horizontal price levels where the market has previously reversed or stalled.
- Wait for price to reach one of these levels. Do not anticipate — let the market come to the level.
- Look for a candlestick pattern that confirms a reaction at the level. For example, a bullish pin bar at support or a bearish engulfing at resistance.
- Enter the trade based on the pattern, with your stop loss placed beyond the level (below support for a buy, above resistance for a sell).
- Set your take profit at the next opposing level, aiming for at least a 1:2 risk-to-reward ratio.
- The hammer: sellers pushed below support to 1.2485 and were rejected; the candle closed back above 1.2510, in the top third of its range.
- Entry 1.2530 only after the next candle closed bullish (1.2528). Stop 1.2478, beyond the hammer's wick. Target 1.2635 at the next resistance: 105 pips of reward for 52 pips of risk = 1 : 2.
- Not every hammer works. The stop beyond the wick is what keeps a failed one small.
This approach filters out noise and focuses your trading on the highest-probability setups. Candlestick patterns at key levels are among the most reliable signals in technical analysis.
