Key Takeaways
- A candlestick shows four prices for one time period in a single shape: open, high, low and close.
- The "body" shows the open-to-close range; the thin "wicks" (or shadows) above and below show the full high-to-low range.
- A green (or white) candle closed higher than it opened; a red (or black) candle closed lower than it opened.
- Single-candle patterns like the Doji and Hammer, and multi-candle patterns like Engulfing and Morning Star, are read as possible signs of a reversal, never as a signal on their own.
- You can practice spotting these patterns on real historical data in our free backtesting tool.
What Is a Candlestick?
A candlestick represents the price action for one fixed period of time, be it 5 minutes, 1 hour, or 1 day, depending on the chart's timeframe. Each candle packs four numbers into a single shape:
- Open: the price when the period began.
- Close: the price when the period ended.
- High: the highest price reached during the period.
- Low: the lowest price reached during the period.
The thick rectangular part of the candle is the body, spanning from the open to the close. The thin lines extending above and below the body are the wicks (also called shadows), spanning from the body out to the period's high and low. A candle with long wicks shows that price moved a long way during the period before being pushed back; a candle with almost no wick shows price moved in a straight line with little resistance.
Bullish vs Bearish Candles
Color is what makes candlestick charts fast to read. The convention varies slightly by platform, but the standard is:
- Bullish (up) candle: usually green or white. The close is higher than the open, meaning buyers were in control over that period.
- Bearish (down) candle: usually red or black. The close is lower than the open, meaning sellers were in control over that period.
Looking across a run of candles, a series of large bullish bodies with short wicks shows a strong, confident uptrend. A series of candles with long wicks in both directions and small bodies shows a market that is indecisive, chopping back and forth without committing to a direction.
Single-Candle Patterns Worth Knowing
- Doji: the open and close are nearly identical, so the body is just a thin line. A Doji shows the period ended in a near-perfect tug of war between buyers and sellers, and is often watched for after a strong trend as an early sign that momentum is fading.
- Hammer: a small body near the top of the candle's range with a long lower wick, at least twice the length of the body. Appearing after a decline, it shows sellers pushed price sharply lower during the period, but buyers fought all the way back, a classic potential reversal signal at the bottom of a move.
- Shooting Star: the inverse of a Hammer: a small body near the bottom of the range with a long upper wick. Appearing after an advance, it shows buyers pushed higher but lost control to sellers by the close, a potential reversal signal at the top of a move.
- Marubozu: a candle with little to no wick at all, body stretching almost the full high-to-low range. A bullish Marubozu shows buyers in complete control from open to close with no pushback; a bearish Marubozu shows the same for sellers.
Multi-Candle Patterns Worth Knowing
- Bullish Engulfing: a small bearish candle followed immediately by a larger bullish candle whose body fully "engulfs" the prior candle's body. Read as a sign buyers have decisively overwhelmed the preceding selling pressure.
- Bearish Engulfing: the mirror image: a small bullish candle followed by a larger bearish candle that fully engulfs it, read as sellers overwhelming the preceding buying pressure.
- Morning Star: a three-candle bottoming pattern: a long bearish candle, then a small-bodied candle that gaps or dips lower, then a long bullish candle closing well into the first candle's body. Read as exhaustion of a downtrend followed by a decisive reversal.
- Evening Star: the mirror image of a Morning Star, appearing at the top of an uptrend: a long bullish candle, a small-bodied indecision candle, then a long bearish candle, read as a potential top.
How to Actually Use Candlestick Patterns
The single most common mistake beginners make is trading a candlestick pattern in isolation, the moment it appears, with no other context. A Hammer that forms in the middle of a range means very little. The same Hammer forming exactly at a well-established support level, discussed in our technical analysis guide, with RSI also showing oversold conditions, is a materially stronger signal because three independent things are agreeing at once.
Treat every candlestick pattern as one input, not a complete trading system: confirm it against the broader trend, a relevant support or resistance level, and ideally one momentum indicator before acting on it.

Frequently Asked Questions
Do candlestick patterns actually work?
They describe real, recurring behavior in how buyers and sellers fight for control over a period, so they are a genuinely useful way to read a chart. They are not a mechanical, guaranteed system; the same pattern plays out differently depending on the broader trend and where it forms relative to support and resistance.
What is the difference between a candlestick chart and a bar chart?
Both display the same four prices (open, high, low, close) for each period. A candlestick chart fills the open-to-close range with a colored body, making direction instantly visible at a glance; a bar chart shows the same information as a vertical line with small open and close ticks, which is more compact but slower to read.
Which timeframe should I use to read candlesticks?
Candlestick patterns can appear on any timeframe, but patterns on higher timeframes (4-hour, daily) are generally considered more significant than the same pattern on a 1-minute chart, simply because more trading activity and more participants are reflected in each candle.
Can I practice candlestick reading without risking money?
Yes. Our backtesting and market replay tool is free, requires no signup to watch a replay, and lets you step through real historical candles on forex, gold, crypto and index charts to practice spotting these patterns before trading live.
