The four prices in every candle (OHLC)
Each candlestick covers a fixed slice of time — one minute, one hour, one day, and so on — and records four prices for that slice. The open is the price at the start of the period; the close is the price at the end. The high is the most expensive trade during the period, and the low is the cheapest. Together these are called OHLC.
The choice of time period, or 'timeframe', changes everything you see. A one-minute candle summarizes 60 seconds of trading, while a daily candle summarizes 24 hours into a single shape. The same market can look calm on one timeframe and volatile on another, so the timeframe is part of the information, not a background detail.
How the body is drawn
The thick rectangular part of a candle is the body, and it spans the distance between the open and the close. If price closed higher than it opened, the candle is usually drawn in one color (commonly green or white) and is called an 'up' candle. If price closed lower than it opened, it is drawn in another color (commonly red or black) and is called a 'down' candle.
The body's length shows how far price moved from open to close, not how much it moved overall. A long body means the open and close were far apart; a very short body means they finished close together, even if price swung around a lot in between.
How the wicks (shadows) are drawn
The thin lines above and below the body are called wicks, shadows, or tails. The top of the upper wick marks the high of the period, and the bottom of the lower wick marks the low. The wicks therefore show the full range price travelled, including moves that were later reversed before the close.
A candle with long wicks and a small body tells you price reached well beyond where it opened and closed but did not stay there. A candle with almost no wicks tells you price moved in mostly one direction and finished near its extreme. Reading wicks is simply reading the range — it is a description of what happened, not a signal about what comes next.
Candlestick patterns and why they are contested
Traders have given names to many individual candles and multi-candle combinations — doji, hammer, engulfing, and dozens more. These 'patterns' are often presented as clues about future direction. It is important to be clear-eyed here: candlestick patterns are subjective and contested, and there is no reliable evidence that they predict prices. Different people identify the same pattern differently, and the same shape can be followed by price moving either way.
Patterns can be a shorthand for describing recent price behaviour, which is a legitimate use. Treating them as forecasts is a different and much weaker claim. Any method that appears to 'work' on past charts can fail going forward, partly because it is easy to spot patterns in hindsight that were not obvious in real time.
Common misreadings and real risks
A frequent mistake is confusing the body with the full range — the close being near the open does not mean price was quiet, because the wicks may show large swings. Another is reading a single candle in isolation, ignoring the timeframe or the surrounding context. Colors are also just conventions; always check which color a given chart assigns to up and down candles.
Beyond chart-reading, the broader context matters: trading is high-risk, and studies of retail traders consistently find that most lose money over time, especially with frequent or leveraged trading. Understanding candlesticks does not change that. This article is not financial advice, and any decision — and its risk — is yours alone.
Where market-data context fits in
Candlesticks show price, but price is only part of the picture. Order-book liquidity — how much buying and selling interest sits near the current price — helps explain why a candle has a long wick or why a move stalled, since thin liquidity can let price travel further on smaller trades.
A data terminal like BIKENZO exists to provide that kind of market-data context, such as liquidity alongside the Bitcoin price. It is an analytics and data tool, not a broker, exchange, or adviser, and it does not predict prices or generate signals. The point of pairing price with liquidity context is understanding, not forecasting.
