How to Read Crypto Charts: Candlesticks, Volume, and Timeframes
A beginner’s guide to crypto line charts and candlesticks, including an OHLC example, volume bars, and common timeframe mistakes.
What you’ll learn
- A candle describes an interval, not an individual transaction.
- Separate the chart’s visible range from each candle’s duration.
- Check the trading pair, price scale, and data source before comparing charts.
Choose what you want the chart to show
A crypto price chart places time on the horizontal axis and price on the vertical axis. A line joins a sequence of recorded prices. A candlestick adds the opening, highest, lowest, and closing prices for each interval. Both describe past observations; neither supplies a reliable prediction by itself.
Start by reading the asset pair. BTC/USD and BTC/USDT are different markets. A quote combined across venues can differ from a single exchange’s price. Before comparing two charts, align their currency, time period, and source as closely as possible.
Read one candlestick from open to close
Consider a fictional one-hour candle that opens at $100, reaches $108, falls as low as $97, and closes at $104. Its body spans $100 to $104. Its upper wick reaches $108 and its lower wick reaches $97. With conventional colors, the body is green because the close is above the open.
The candle does not tell you whether the high happened before the low. Many different sequences of trades can produce the same four numbers. The candle’s open-to-close gain is 4%, even though the high is 8% above the open. Reading a wick as a return would mix two different measurements.
Open-to-close change = (close ÷ open − 1) × 100

Separate candle interval from chart range
A chart can show seven days of history using one-hour candles. Seven days is the visible range; one hour is the interval summarized by each candle. Zooming into a short move without noticing the range can make a small fluctuation look like the dominant trend.
The vertical scale also changes the impression. A tightly cropped scale makes a small dollar move look large. A logarithmic scale gives equal space to equal percentage moves, while a linear scale gives equal space to equal absolute changes. Check the scale before comparing the steepness of two charts.
Use volume and hover details for context
Read volume bars with their units and interval. A bar might summarize trades during a candle, while a tooltip elsewhere might report a rolling 24-hour total. Those are different measures. A line that looks quiet can still sit above substantial trading activity.
On CoinBee, open the price chart, select the period, and inspect available point details. Treat an exchange-pair chart as that specific market. If historical points are missing, do not assume a straight segment means the market traded smoothly. Charts help organize evidence; they cannot explain every move without further research.
Common questions
Does a green candle mean the asset is up today?
It means the candle closed above its own open under the usual color convention. The asset can still be down over the full day.
Can a candlestick show which price happened first?
It shows the open and close, plus the high and low. It does not reveal the order of all trades inside the interval.
