Candlesticks, often referred to as K-lines, are a method of recording price movements over a specific period. A candlestick chart visually represents these price changes in the market and is a fundamental tool in technical analysis. Whether you're analyzing stocks, ETFs, futures, or forex, understanding candlesticks and candlestick charts is essential for observing price trends.
This guide will explain what candlesticks are, how to read candlestick charts, and introduce 16 common candlestick patterns.
What Are Candlesticks?
Candlesticks (also known as K-lines or candle charts) are graphical representations of price movements for a specific timeframe—such as daily, weekly, or monthly. Each candlestick is formed using four key prices: the open, high, low, and close. Because of their rectangular shape and wicks, they are often called candle charts.
Candlesticks are generally categorized into two types based on price movement:
- Bullish Candlestick (Yang Line): The closing price is higher than the opening price. This is often colored green or white in international contexts, though in Taiwan, it is red.
- Bearish Candlestick (Yin Line): The closing price is lower than the opening price. This is commonly shown in red internationally, but in Taiwan, it appears as green.
The body of the candle represents the opening and closing prices, while the wicks (or shadows) indicate the highest and lowest prices during the period.
The length of the candle body helps traders gauge the extent of price movement. Regardless of color, the highest price is always at the top of the wick, and the lowest is at the bottom.
Important Note:
In Taiwan, the market follows a "red up, green down" convention—meaning rising prices are shown in red and falling prices in green. However, in most other global markets, including the US and Europe, the convention is "green up, red down."
Be mindful of this difference when using international trading platforms or charting tools.
Candlesticks Provide More Information Than Line Charts
Price data during trading hours is vast and continuously updating. While it’s useful to simplify this information for analysis, oversimplification can lead to missing critical insights.
Common types of price charts include candlestick charts, bar charts, and line charts. Among these, candlestick charts offer more detail than simple line charts (which typically only show closing prices). Candlesticks display the open, high, low, and close—offering insight into market sentiment at the start, end, and most optimistic and pessimistic points of the trading period.
Candlesticks Can Represent Different Timeframes
Candlestick charts can be viewed across various timeframes. Most trading platforms and charting websites like TradingView allow users to switch between periods:
- Daily Candlesticks: Show one day of price movement; popular with short-term traders.
- Weekly Candlesticks: Aggregate a week’s data into one candle.
- Monthly Candlesticks: Reflect a full month of trading.
On platforms like TradingView, users can easily toggle between these timeframes to suit their analysis needs.
How to Read a Candlestick Chart
A candlestick chart is simply a sequence of individual candlesticks. These charts are widely available on financial websites and broker platforms. Here’s what to look for:
- Timeframe Selection: Choose between minute, hourly, daily, weekly, or monthly views.
- Volume: Trading volume is often displayed below the price chart.
- OHLC Prices: Open, High, Low, and Close values for each period.
- Candlestick Patterns: The visual representation of OHLC data.
Most trading apps and platforms allow users to customize these settings for detailed technical analysis.
16 Common Candlestick Patterns Explained
The shape of a candlestick is determined by the relationship between its open, high, low, and close prices. These four values reflect market sentiment—optimism, pessimism, and indecision—throughout the trading period.
Traders use these patterns to gauge market emotion and compare current conditions with historical trends. While candlestick patterns can provide valuable insights, they are not foolproof predictors of future price movements. They should be used in conjunction with other analysis tools.
1. Bullish Candle with Upper and Lower Shadows
This pattern occurs when the closing price is above the opening price (bullish), and both upper and lower wicks are present.
- Equal Upper and Lower Shadows: Indicates a battle between buyers and sellers. The price fell but found support, then rose but faced resistance. The close above the open suggests buyers ultimately had the upper hand.
- Longer Lower Shadow: Signals strong buying pressure after a decline. Sellers pushed the price down, but buyers drove it back up.
- Longer Upper Shadow: Shows that buyers attempted to push the price higher, but sellers dominated later in the session.
2. Bullish Candle with Lower Shadow (Bullish Hammer)
The price opened, fell during the session, but then recovered to close near the high. A long lower shadow indicates strong buying interest at lower price levels.
3. Bullish Candle with Upper Shadow (Inverted Hammer)
The price rose after opening but encountered selling pressure, pulling the close down from the high. A long upper shadow suggests resistance at higher prices.
4. Bullish Candle with Long Lower Shadow (Bullish Pin Bar)
The price dropped significantly after opening but was bought up aggressively, closing at the session high. This indicates a strong reversal of sentiment.
5. Bullish Candle with Long Upper Shadow (Shooting Star)
The price opened and rose initially but faced heavy selling, closing only slightly above the open. This can signal a potential reversal after an uptrend.
6. Bullish Candle with No Shadows (Marubozu)
The open equals the low, and the close equals the high. This shows strong buying pressure throughout the session.
7. Bearish Candle with Upper and Lower Shadows
This pattern forms when the closing price is below the opening price (bearish), with both upper and lower wicks.
- Equal Shadows: Indicates indecision. The price moved both up and down during the session.
- Longer Lower Shadow: Suggests that sellers dominated, but buyers made a partial recovery by the close.
- Longer Upper Shadow: Shows that buyers tried to push the price up but were overwhelmed by sellers.
8. Bearish Candle with Lower Shadow
The price opened and declined but recovered somewhat before the close. A long lower shadow indicates that buyers are starting to emerge.
9. Bearish Candle with Upper Shadow
The price opened, rose briefly, but then fell to close near the low. This shows that any buying interest was quickly overcome by sellers.
10. Bearish Candle with Long Lower Shadow (Bearish Hammer)
The price fell after opening but recovered significantly by the close. This can indicate a potential trend reversal.
11. Bearish Candle with Long Upper Shadow (Hanging Man)
The price rose after opening but then fell sharply to close near the low. This is often seen as a bearish signal after an uptrend.
12. Bearish Candle with No Shadows (Bearish Marubozu)
The open equals the high, and the close equals the low. This indicates strong selling pressure throughout the session.
13. Four-Price Doji (One-Line Candle)
The open, high, low, and close are all the same. This reflects extreme indecision or a halted market and is relatively rare.
14. T-Line Candle
The open and close are the same, and there is a lower shadow. This suggests that sellers pushed the price down, but buyers brought it back to the open.
15. Inverted T-Line Candle
The open and close are the same, with an upper shadow. It indicates buying interest that was met with selling pressure.
16. Cross-Line Candle (Doji)
The open and close are equal, with both upper and lower shadows. This pattern signals market indecision and is often considered a reversal indicator when it appears after a strong trend.

Frequently Asked Questions
What is the difference between a candlestick and a bar chart?
Candlestick charts and bar charts both display OHLC data, but candlesticks offer a more visual and intuitive representation due to their colored bodies and wicks. Bar charts use vertical lines and horizontal ticks to indicate open and close.
Can candlestick patterns predict market movements accurately?
While candlestick patterns can indicate potential trend reversals or continuations, they are not 100% reliable. They should be used alongside other technical indicators and fundamental analysis.
Why do candlestick colors vary between regions?
In Taiwan, red typically represents price increases and green decreases. However, most international platforms use green for upward movements and red for downward ones. Always check the color scheme of your trading platform.
How do I choose the right timeframe for candlestick analysis?
Short-term traders often use daily or hourly candles, while long-term investors may prefer weekly or monthly charts. The choice depends on your trading strategy and goals.
What does a long wick indicate?
A long upper wick suggests resistance at higher prices, while a long lower wick indicates support at lower levels. Both reflect rejection of price extremes.
Are candlestick patterns applicable to all financial markets?
Yes, candlestick analysis is used across various markets, including stocks, forex, commodities, and cryptocurrencies. The principles remain the same regardless of the asset.
