Candlestick Patterns
How to read candlestick charts and the most common patterns traders watch.
⏱️ ~8 min read
Key Takeaways
- Each candlestick shows the open, high, low, and close price for a given time period
- The 'body' shows the open-to-close range; the 'wicks' (or shadows) show the high and low
- Certain recurring shapes and sequences are widely watched by traders as potential signals of reversals or continuations
- Candlestick patterns are probabilistic observations, not guarantees — they're typically used alongside other analysis
Anatomy of a candlestick
A candlestick chart displays four price points for each time period (a day, an hour, five minutes — whatever interval the chart is set to): the open (price at the start of the period), close (price at the end), high (highest price reached), and low (lowest price reached).
The 'body' of the candle is a rectangle spanning from the open to the close. If the close is higher than the open, the body is typically shown in one color (often green or white); if the close is lower than the open, it's shown in another color (often red or black). Thin lines extending above and below the body — called wicks or shadows — show the high and low for the period.
Example: Reading a single candle
A daily candle has: Open = $100, High = $108, Low = $97, Close = $105.
Because the close ($105) is higher than the open ($100), the body is 'bullish' (often green), spanning from $100 to $105.
The upper wick extends to $108 (the high), and the lower wick extends to $97 (the low) — showing that price moved both above and below the body's range during the period before settling at the close.
Single-candle patterns
A 'doji' is a candle where the open and close are very close together, producing a tiny or nonexistent body — often interpreted as a sign of indecision between buyers and sellers during that period.
A 'hammer' has a small body near the top of its range with a long lower wick, often appearing after a downtrend — some traders interpret this as a potential sign that sellers pushed the price down during the period, but buyers stepped in and pushed it back up by the close. A 'shooting star' is visually similar but appears after an uptrend, with a long upper wick, sometimes interpreted as the opposite signal.
Multi-candle patterns
A 'bullish engulfing' pattern occurs when a small bearish (down) candle is immediately followed by a larger bullish (up) candle that 'engulfs' the prior candle's body — sometimes interpreted as a potential shift from selling to buying pressure. A 'bearish engulfing' pattern is the mirror image, potentially signaling a shift from buying to selling pressure.
A 'morning star' is a three-candle pattern sometimes associated with potential bottoms: a long bearish candle, followed by a small-bodied candle (showing indecision), followed by a bullish candle. An 'evening star' is the mirror-image pattern sometimes associated with potential tops.
How traders typically use these patterns
Candlestick patterns are generally used as one input among several — traders often look for a pattern to occur near a meaningful price level (like support or resistance, covered in its own lesson) or in combination with other indicators, rather than treating a pattern in isolation as a standalone signal.
It's also worth noting that any individual pattern can and does fail to 'work' as expected a significant portion of the time — these patterns describe tendencies observed across many historical instances, not guarantees for any specific future occurrence.
Context matters more than the pattern alone
The same candlestick shape can carry different implications depending on where it occurs — a hammer appearing after a long downtrend is interpreted differently than the same-looking candle appearing in the middle of a sideways, range-bound market. Volume (covered in its own lesson) accompanying a pattern is also often considered alongside the pattern's shape.
Frequently Asked Questions
Are candlestick patterns scientifically proven to work?+
Candlestick patterns are based on historical observation and widespread use among traders rather than formal proof of predictive power — academic studies on their effectiveness have produced mixed results, and many practitioners treat them as one input among several rather than standalone signals.
What time frame should I use for candlestick charts?+
This depends on your trading or analysis time frame — day traders might use minute or hourly candles, while longer-term investors might look at daily, weekly, or monthly candles. The same pattern can appear (and be interpreted) across different time frames.
Do candlestick patterns work the same for all assets?+
Patterns are commonly applied across stocks, ETFs, currencies, and other assets, but liquidity, volatility, and typical trading behavior can vary by asset, which may affect how reliably any given pattern tends to play out.
