How to Read Candlestick Charts
Candlesticks are a compact way to see open, high, low and close prices. This guide shows how to read them without treating chart patterns as predictions.
What Are Candlestick Charts?
Candlestick charts are the most popular method of displaying price data in trading. Developed in 18th-century Japan, they show four key price points for each time period: open, high, low, and close (OHLC).
Each "candle" represents a specific time period (1 minute, 5 minutes, 1 hour, 1 day, etc.). Day traders typically use 1-minute, 5-minute, or 15-minute candles.
Anatomy of a Candlestick
Bullish (Green/White) Candle
Price closed higher than it opened. The body (thick part) shows the range between open and close. Wicks (thin lines) show the high and low for the period.
Bearish (Red/Black) Candle
Price closed lower than it opened. The body shows the range between open and close, with wicks indicating the period's high and low.
Key Components:
- Body: The thick part showing the range between open and close prices
- Upper Wick (Shadow): Line above the body showing the period's high
- Lower Wick (Shadow): Line below the body showing the period's low
- Color: Green/white = bullish (close > open), Red/black = bearish (close < open)
What one candle can tell you
Body size
A long body means the open and close were far apart during that candle. A short body means they were close together. Neither one tells you what the next candle must do.
Upper wick
The upper wick shows how far price traded above the body. A long upper wick tells you higher prices were reached and not maintained through the close of that candle.
Lower wick
The lower wick shows how far price traded below the body. A long lower wick tells you lower prices were reached and not maintained through the close.
Context
The same candle can mean something different after a strong trend, inside a quiet range, at the open, or during thin trading. Start with the price information before attaching a pattern name.
Common pattern names — and their limits
Names such as hammer, shooting star and engulfing candle are shorthand for shapes traders commonly discuss. They are descriptions, not automatic buy or sell signals.
Hammer
A relatively small body with a longer lower wick. It shows that price traded lower during the candle and recovered before the close.
Shooting star
A relatively small body with a longer upper wick. It shows that price traded higher during the candle and gave back part of the move before the close.
Engulfing candle
A candle whose body covers the prior candle's body. Traders often pay attention to it after a directional move, but it still needs context.
Doji
A candle where open and close are very close. It shows little net movement between those two prices; by itself, it does not tell you which side will win next.
Read the sequence, not just the shape
A useful way to read a chart is to ask four simple questions:
- Where did price open and close? That tells you the candle body.
- How far did price travel above and below? That tells you the wicks.
- How does this candle compare with the previous few candles? Size and volatility are relative.
- What was happening around it? Check volume, spread, time of day and nearby price levels.
Important Warnings
- • No pattern works 100% of the time. Candlestick patterns show probabilities, not certainties.
- • Context matters. The same pattern can have different meanings depending on trend, volume, and location.
- • Confirm with other indicators. Don't trade based on patterns alone. Use volume, trend, and support/resistance.
- • Practice extensively. Pattern recognition takes time to develop. Use paper trading to practice without risk.
A simple way to practice
Pick one liquid stock and review a short section of historical intraday candles. Cover the candles to the right, describe only what the visible candles show, then reveal the next section. Keep notes on what you observed versus what actually happened. The goal is to get better at reading price information, not memorizing shapes and forcing predictions.
