What is a Candlestick?
A candlestick is a charting tool that captures how an asset's price behaved within a defined time frame. Every single candle encodes four essential data points — the Open, High, Low, and Close — giving traders an immediate snapshot of who held the upper hand during that period: the buyers or the sellers.
The price at which the asset began trading at the start of the time period.
The final price at which the asset traded before the period ended.
The highest price reached during the entire time period.
The lowest price reached during the entire time period.
Components of a Candlestick
Every candlestick is made up of two main parts: the body and the wick (also called the shadow). Together, these two elements tell the complete story of what happened during a trading period.
Anatomy of a Candlestick
Bullish (Green) CandleThe body (filled rectangle) spans the distance between the Open and the Close. The thin wick extends from the High down to the Low, showing the full range of prices reached during the period.
The body (also called the "real body") is the wide rectangular section of the candlestick. It represents the range between the opening and closing prices for the time period.
- Bullish Body
When the close is higher than the open, the body is filled green (or white). This indicates buyers were in control during the period — prices moved up.
- Bearish Body
When the close is lower than the open, the body is filled red (or black). This indicates sellers were in control — prices moved down.
- Body Size Matters
A large body signals strong conviction. A small or tiny body (like a Doji) signals indecision between buyers and sellers, often preceding a reversal.
- No Body (Doji)
When open and close are equal, the body collapses to a single line. Doji candles are powerful signals of market indecision and potential trend changes.
The thin lines extending above and below the body are called wicks (or shadows). They reveal the full price range tested during the period — showing how far buyers and sellers pushed prices beyond the open/close range.
- Upper Wick
The line above the body stretches from the top of the body to the session's high. A long upper wick means buyers pushed prices up, but sellers rejected the move and drove prices back down.
- Lower Wick
The line below the body extends from the bottom of the body to the session's low. A long lower wick means sellers pushed prices down, but buyers stepped in and drove prices back up — a bullish sign.
- No Wick (Marubozu)
A candle with no wicks at either end (called a Marubozu) indicates one side was completely in control from open to close with no pushback from the other side.
- Wick vs. Body Ratio
A long wick relative to a small body signals rejection of that price level. Traders watch for wicks forming at key support/resistance levels as reversal signals.
Candle Colors
The color of a candlestick is the fastest signal a trader receives. At a glance, color reveals whether buyers or sellers controlled the period — and how decisively.
Bullish vs. Bearish Candle
In a bullish candle the Close sits above the Open — prices rose. In a bearish candle the Open sits above the Close — prices fell. The High and Low (wick tips) mark the full range tested in both cases.
The closing price is higher than the opening price.
Buyers won the period. The stronger the green candle and the larger the body, the more conviction behind the buying pressure.
- Strong green candles in an uptrend confirm momentum.
- A large green candle after a period of consolidation can signal a breakout.
- Green engulfing candles at support are powerful bullish reversal signals.
The closing price is lower than the opening price.
Sellers won the period. A large red body indicates strong selling pressure and bearish conviction in the market.
- Strong red candles in a downtrend confirm selling momentum.
- A large red candle breaking below support signals a breakdown.
- Red engulfing candles at resistance are powerful bearish reversal signals.
How to Read a Candlestick
Reading a candlestick comes down to a simple, repeatable sequence. Ask the same four questions every time — in the same order — and the candle will tell you who was in control and how confident they were.
The 4-Step Read (works for any candle)
- 1
Look at the color first.
Green = buyers won the period. Red = sellers won. This is your headline before any detail.
- 2
Find the Open and the Close.
On a green candle the bottom edge of the body is the Open and the top edge is the Close. On a red candle it flips — the top edge is the Open and the bottom edge is the Close.
- 3
Measure the body.
A tall body means a strong, decisive move. A short body means hesitation or a balanced fight between buyers and sellers.
- 4
Read the wicks.
Long upper wick = buyers were rejected. Long lower wick = sellers were rejected. Short or no wicks = one side dominated the entire period.
A green candle means price closed higher than it opened. Here is how to read it from bottom to top:
- ①Open — start at the bottom edge of the body. This is where the period began.
- ②Close — finish at the top edge of the body. This is where the period ended, and it is higher than the open.
- ③Body — the green rectangle between Open and Close. A tall body = buyers pushed price up with conviction.
- ④Wicks — the thin lines above and below. The top tip is the High, the bottom tip is the Low. Long wicks show prices were pushed then rejected.
Takeaway: green candle = buyers in control. The bigger the body, the stronger the buying pressure.
A red candle means price closed lower than it opened. Here is how to read it from top to bottom:
- ①Open — start at the top edge of the body. This is where the period began.
- ②Close — finish at the bottom edge of the body. This is where the period ended, and it is lower than the open.
- ③Body — the red rectangle between Open and Close. A tall body = sellers pushed price down with conviction.
- ④Wicks — the thin lines above and below. The top tip is the High, the bottom tip is the Low. Long wicks show prices were pushed then rejected.
Takeaway: red candle = sellers in control. The bigger the body, the stronger the selling pressure.
A Simple Memory Hook
Green: Open at the bottom → Close at the top (price went up). Red: Open at the top → Close at the bottom (price went down). The body always runs from Open to Close; the wicks always stretch to High and Low. Remember that and you can read any candle in seconds.
How Traders Use Candlesticks
Candlestick charts are the most widely used chart type among active traders. They provide far more information than a simple line chart, enabling traders to make faster, more informed decisions.
Reading Market Sentiment
Candlesticks instantly reveal the emotional state of the market. A series of large green candles shows buyers are confident and aggressive. A series of small, mixed candles shows uncertainty. Traders read this sentiment to align their trades with the prevailing mood.
Identifying Support & Resistance
Long wicks at specific price levels show that the market repeatedly rejects those prices. A cluster of lower wicks at the same level signals strong support. Upper wicks at the same level signal strong resistance. Traders use these levels to set entries, stops, and targets.
Spotting Reversal Patterns
Certain candlestick formations — like the Hammer, Shooting Star, Engulfing, and Doji — are classic reversal signals. When these patterns appear at key support or resistance zones, traders take them as high-probability signals that the trend is about to change direction.
Confirming Trend Continuation
Candlesticks also signal that a trend will continue. Patterns like the Three White Soldiers (three consecutive large green candles) or the Three Black Crows (three consecutive large red candles) confirm strong directional momentum and give traders confidence to hold or add to positions.
Combining with Technical Indicators
Candlestick patterns are most powerful when confirmed by technical indicators. For example, a Hammer candle at support with an RSI below 30 (oversold) and rising volume is a much stronger buy signal than any one signal alone. Professional traders always look for confluence.
Setting Stop Losses & Targets
The structure of a candle helps define risk. Traders typically place stop losses just below the low of a bullish candle or just above the high of a bearish candle. The wick extremes serve as natural reference points for where the market has already proven to reject prices.
