How to read a crypto chart
What the bars and lines mean, and what they can't tell you.
A crypto chart shows past prices over time. Most use candlesticks, where each candle shows the opening, closing, highest and lowest price for a period, plus a volume bar for how much was traded. Charts describe what happened; they can't reliably predict what happens next.
Candlesticks
Timeframes
Each candle can cover a minute, an hour, a day or a week. The same coin can look like it's crashing on a 1-hour chart and rising on a weekly one. Always check the timeframe first.
Common chart tools
- Volume: bars under the chart showing how much was traded. Big moves on high volume are generally taken more seriously than moves on thin volume.
- Moving averages: lines that smooth out past prices, such as the 50-day or 200-day average.
- Support and resistance: price levels where buying or selling has shown up before. They're rough zones, not guarantees.
- Log scale: shows percentage changes evenly. For long histories like Bitcoin's, a log chart is easier to read than a normal (linear) one.
What charts can't do
Chart patterns are open to interpretation, and research on trading generally finds most active traders lose money. Anyone selling "can't-lose" chart signals is a red flag. See day trading crypto.
