What is a candlestick in crypto trading?
A candlestick in crypto trading is a visual element on a price chart that communicates four pieces of information for a single time period: where the price opened, where it closed, the highest price reached, and the lowest price reached. Each candlestick has a rectangular body — the block between the open and close — and thin lines called wicks extending above and below. A green body means price closed higher than it opened, indicating buying pressure. A red body means price closed lower, indicating that sellers were in control during that period.
What do the colors of a candlestick mean?
Candlestick colors indicate whether price increased or decreased during that specific time period. A green or white candlestick means the closing price was higher than the opening price — buyers were in control and price moved upward during that session. A red or black candlestick means the closing price was lower than the opening price — sellers dominated and price fell. The intensity of the color carries no additional meaning; it is simply a visual cue to instantly identify whether a period was bullish or bearish without needing to read the exact open and close price values.
What are the wicks on a candlestick?
The wicks — also called shadows — are the thin lines that extend above and below the main body of a candlestick. The upper wick extends from the top of the body to the highest price reached during the time period. The lower wick extends from the bottom of the body to the lowest price reached. Long wicks indicate that price traveled far from the body before reversing, often signaling strong rejection at those extreme price levels. Short wicks suggest price remained close to the open and close throughout the session with minimal volatility at the extremes.
Calibration Check
A candlestick's color tells you whether the overall market is bullish or bearish.
A candlestick's color only tells you what happened during that one specific time period — not the overall market direction. A single red candlestick within a strong uptrend is completely normal and does not signal the uptrend has ended. Overall market direction is determined by analyzing a series of candlesticks across a longer timeframe, identifying patterns of higher highs and higher lows for an uptrend, or lower highs and lower lows for a downtrend. Judging broader market direction from a single candle's color is one of the most common beginner misreadings in technical analysis.
A longer candlestick body always means higher trading volume.
A longer candlestick body means price moved a greater distance between its opening and closing price — it has no direct relationship with trading volume. A large-bodied candle can appear on relatively low volume if the few trades that occurred pushed price significantly in one direction. Conversely, high-volume periods can produce small-bodied candles if buying and selling pressure are roughly balanced. Trading volume is displayed separately as bar graphs below the price candles and must be analyzed alongside candlestick size rather than assumed to be embedded within the candle's appearance.
Candlestick charts and bar charts show different price information.
Candlestick charts and bar charts display exactly the same four data points per period: the open, high, low, and close prices. The difference is purely visual presentation. A bar chart uses a vertical line with two horizontal ticks, while a candlestick uses a colored rectangular body and thin wicks. Both communicate identical OHLC information — the candlestick format simply makes the relationship between open and close more immediately visible through color coding, which is why it became the dominant format for most traders over bar charts.
