How to read a crypto chart

What the bars and lines mean, and what they can't tell you.

BeginnerAbout 6 minutesReviewed October 26, 2026
The short answer

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

The thick body runs from open to close; the thin wicks show the high and low. Green (or hollow) means the price closed higher than it opened; red means lower.

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

Be skeptical

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.

Frequently asked questions

What does a green candle mean?

The price closed higher than it opened during that period.

Which timeframe should I use?

It depends on your question. Long-term holders usually look at daily or weekly charts; short-term charts are noisy.
