What Is a Candlestick Chart?

A candlestick chart is a type of price chart that displays the open, high, low, and close prices of a stock (or any financial instrument) for a specific period — such as one day, one hour, or one minute. Each unit of time is represented by a single “candlestick” or “candle.”

Unlike simple line charts that only show closing prices, candlestick charts convey much more information at a glance, allowing traders to see not only where price ended up but also how it moved within that period.

Anatomy of a Single Candlestick

Each candlestick has two main components:

1. The Body

   • Represents the price range between the open and close of that time period.

   • If the closing price is higher than the opening price, the body is typically hollow or colored green/white (indicating bullish movement).

   • If the closing price is lower than the opening price, the body is filled or colored red/black (indicating bearish movement).

2. The Wicks (or Shadows)

   • The thin lines above and below the body represent the high and low prices reached during the period.

   • The upper wick extends from the top of the body to the highest price.

   • The lower wick extends from the bottom of the body to the lowest price.

Why Are Candlestick Charts Popular?

Candlestick charts originated in Japan in the 18th century, created by rice traders to analyze price movements. Today, traders around the world use them because:

• They display detailed price information in a compact form.

• They visually highlight buying and selling pressure within the period.

• Patterns formed by multiple candlesticks help predict future price action.

What Information Does Each Candlestick Provide?

Each candlestick answers four essential questions:

• What was the opening price?

• What was the closing price?

• What was the highest price during the period?

• What was the lowest price during the period?

Because of this, candlestick charts can show market volatility, momentum, and sentiment better than many other chart types.

Timeframes of Candlestick Charts

Candlesticks can represent any timeframe, depending on the trader’s preference and strategy:

• 1-minute candle: Each candlestick shows price action during one minute.

• 5-minute candle: Each candle covers five minutes.

• Hourly candle: Each candle shows one hour.

• Daily candle: Each candle represents one day.

• Weekly or monthly candles: For longer-term analysis.

The choice of timeframe affects how the chart looks and what kind of signals can be observed.

Common Candlestick Patterns and What They Mean

One of the most powerful uses of candlestick charts is recognizing patterns formed by one or more candlesticks. These patterns can indicate potential trend reversals or continuations.

Single-Candlestick Patterns

• Doji: The open and close prices are almost the same, creating a very small body. It suggests indecision in the market.

• Hammer: A small body near the top with a long lower wick. Often found at the bottom of downtrends and indicates a possible reversal upwards.

• Shooting Star: Small body near the bottom with a long upper wick, usually signaling a bearish reversal after an uptrend.

Multiple-Candlestick Patterns

• Engulfing Pattern: A larger candle completely “engulfs” the previous candle’s body.

  • Bullish engulfing signals a potential upward reversal.

  • Bearish engulfing signals a possible downward reversal.

• Morning Star and Evening Star: Three-candle patterns indicating major reversals. Morning star suggests bullish reversal; evening star suggests bearish reversal.

• Three White Soldiers and Three Black Crows:

  • Three White Soldiers: Three consecutive bullish candles, often signaling a strong uptrend.

  • Three Black Crows: Three bearish candles, signaling a downtrend.

How Traders Use Candlestick Charts

1. Identify Market Sentiment

• Bullish candles indicate buying pressure.

• Bearish candles indicate selling pressure.

• Long wicks show rejection of higher or lower prices.

2. Spot Reversals and Continuations

Candlestick patterns help predict when trends might change or continue, helping traders decide when to buy or sell.

3. Combine With Other Indicators

Candlestick analysis is often combined with moving averages, RSI, or volume to increase the reliability of trading signals.
