Candlestick charts originated in 18th-century Japan, where rice trader Munehisa Homma used them to track rice prices and predict future market movements. Today they are the preferred chart type for the vast majority of Forex traders worldwide — and for good reason. Candlesticks contain more information than any other chart type, and learning to read them fluently is one of the highest-value skills in technical analysis.
Anatomy of a Single Candlestick
Each candlestick represents price movement over a specific time period (1 minute, 1 hour, 1 day — depending on your chart timeframe). Every candlestick has four data points:
- Open: The price at which the period started
- Close: The price at which the period ended
- High: The highest price reached during the period
- Low: The lowest price reached during the period
The rectangular body of the candle represents the range between open and close. The thin lines extending above and below the body are called wicks (or shadows) and represent the high and low.
Bullish candle (usually white/green): Close is higher than open — buyers were in control during this period.
Bearish candle (usually black/red): Close is lower than open — sellers dominated.
What Candlesticks Tell You About Market Psychology
Each candle is a story about the battle between buyers and sellers. Learning to read this story is what price action trading is about:
- Long body, small or no wicks: Strong conviction in one direction. Buyers/sellers dominated throughout the period with little opposition.
- Small body, long wicks: Indecision. Price moved significantly in both directions but closed near where it opened — neither side won decisively.
- Long lower wick, small upper wick: Buyers rejected lower prices. Selling pressure was overcome — potential bullish signal.
- Long upper wick, small lower wick: Sellers rejected higher prices. Buying pressure was overcome — potential bearish signal.
Key Single-Candle Patterns
Doji
A doji forms when open and close are equal or very close, creating a cross or plus-sign shape. It signals complete indecision — neither buyers nor sellers won the session. In context (after a strong trend), a doji often signals a potential reversal.
Hammer and Hanging Man
Both have a small body at the top and a long lower wick (at least twice the body length). A hammer forms at the bottom of a downtrend and signals potential bullish reversal — sellers pushed prices down but buyers drove it back up by the close. A hanging man has the same shape but appears at the top of an uptrend, signalling potential bearish reversal.
Shooting Star and Inverted Hammer
The opposite of the hammer — small body at the bottom, long upper wick. A shooting star at the top of an uptrend signals bearish reversal. An inverted hammer at the bottom of a downtrend signals potential bullish reversal (less reliable than the hammer).
Spinning Top
A small body with wicks of roughly equal length on both sides. Like the doji, it signals indecision. Less significant than a doji but worth noting in context.
Key Two and Three Candle Patterns
Engulfing Patterns
A bullish engulfing pattern occurs when a bearish candle is followed by a bullish candle whose body completely engulfs the previous candle’s body. It signals a strong shift from selling to buying pressure and is one of the most reliable reversal signals.
A bearish engulfing is the opposite — a bearish candle completely engulfs a preceding bullish candle, signalling a shift to selling.
Morning Star and Evening Star
The morning star is a three-candle bullish reversal pattern: a large bearish candle, followed by a small-bodied candle (the star — showing indecision), followed by a large bullish candle. It signals a potential bottom.
The evening star is the bearish equivalent: large bullish candle, small star, large bearish candle. It signals a potential top.
Three White Soldiers and Three Black Crows
Three consecutive bullish candles with progressively higher closes (three white soldiers) indicate strong buying momentum. Three consecutive bearish candles with progressively lower closes (three black crows) signal strong selling pressure.
Using Candlestick Patterns Effectively
Candlestick patterns work best when:
- They appear at key levels: A hammer at strong support is far more significant than a hammer in the middle of a range.
- They are confirmed: Wait for the next candle to confirm the signal before entering. A bullish engulfing followed by another bullish candle is far more reliable than acting on the engulfing alone.
- They align with the broader trend: Bullish reversal patterns are more reliable in an uptrend (pullback entries) than in a strong downtrend.
- Volume or momentum confirms: Patterns accompanied by increasing volume (on instruments where volume data is available) carry more weight.
Key Takeaway: Candlestick patterns are tools for reading market psychology, not magic signals. A single pattern never guarantees a move — it simply shifts the probability. Always combine candlestick analysis with support/resistance levels and overall trend direction for highest-probability setups.
