How to Read Crypto Charts, From Candles to Moving Averages

A crypto chart is a record of every trade on one market, plotted over time, and learning how to read crypto charts comes down to five parts: candles, timeframe, volume, the price levels where moves have stalled before, and a moving average. Each part answers a different question about what has already happened. The decision you are left with is how much weight to give a picture that only looks backward.

Bitcoin (BTC), the largest cryptocurrency by market value, traded at $77,982.89 at 08:50 UTC on 2 November 2026, according to CoinGecko, up 0.50% over 24 hours. CoinGecko recorded $57.49 billion of Bitcoin trading volume over those 24 hours, with a low of $77,370.05 and a high of $78,133.57.

This guide shows how to read crypto charts using that Bitcoin data, then covers what no chart can show you.

What Does a Candlestick Show?

A candlestick shows four prices for one slice of time: the opening trade, the highest trade, the lowest trade and the closing trade. Coinbase's developer documentation defines the open as the "Opening price (first trade) in the bucket interval" and the close as the "Closing price (last trade) in the bucket interval." The thick body runs from open to close, thin wicks mark the high and low, and a candle that closed above its open is usually green. Think of it as a till receipt for one period: it records the sales, never the reasons.

That 24-hour window makes a usable candle. Working back from CoinGecko's 0.50% rise, Bitcoin opened that window near $77,595 and ended at $77,982.89, so the body is about $388 and the candle is green. The high sits about $151 above the last price and the low about $225 below the open. The full range was about $764, so the body filled roughly half of it. Learning how to read candlestick charts in crypto is mostly this arithmetic: a small body between long wicks shows trading both ways without a clear winner.

Before You Read a Chart: What You Need

Reading crypto charts well starts with four free settings.

• A named data source. Block Insider's Bitcoin price page says its chart is powered by CoinGecko, which blends many exchanges, some with volume that is hard to verify. A Coinbase chart shows only Coinbase trades.
• A timeframe that matches your plans. Long-term holders and day traders need different candles.
• Volume beside the price. A move without its volume is half a reading.
• The time setting. Crypto never closes, so a "daily" candle starts where the platform sets the day. Coinbase stamps each candle with a UNIX start time.

Which Chart Timeframe Fits Your Purpose?

The timeframe sets how much time one candle covers, and Coinbase's Advanced Trade API offers nine settings, from one minute to one day. Four of them cover most readers.

15-minute candles

• Candles in 30 days: 2,880
• Shows well: moves inside one session
• Suits: active traders timing an order
• Drawback: one large order can stretch a wick that means nothing later

1-hour candles

• Candles in 30 days: 720
• Shows well: the shape of a day or a week
• Suits: buyers spreading a purchase over a few days
• Drawback: overnight swings fill the screen

4-hour candles

• Candles in 30 days: 180
• Shows well: swings lasting several weeks
• Suits: readers checking a trend once or twice a day
• Drawback: start times differ by platform, so two charts can disagree

1-day candles

• Candles in 30 days: 30
• Shows well: trends running for months
• Suits: long-term buyers and most beginners
• Drawback: an intraday crash and recovery shrink into one wick

What Does Trading Volume Tell You?

Trading volume tells you how much changed hands while a candle formed. Coinbase defines it as "Volume of trading activity during the bucket interval," and most charts draw it as a bar under each candle. That plain bar, compared with the bars beside it, is the crypto volume indicator most beginners need.

A move on volume well above the past week's bars had more trades behind it. CoinGecko's $57.49 billion means little alone; set against the seven previous daily bars, it shows whether a session was busy or quiet. On a small token, knowing how to read crypto charts means checking volume first, for reasons the risk section explains.

Where Support, Resistance and Moving Averages Fit

Support and resistance are price zones where a fall or a rise has stalled before, and a moving average shows which way the trend has run. Support is where buying has stopped declines, resistance where selling has capped rallies, and marking both is a core part of how to read crypto charts.

Between 13 and 28 October 2026, Bitcoin's daily close stayed between $80,029 and $84,082, according to CoinGecko's historical data, so $80,000 looked like a floor. On 29 October the close was $77,839, which is 4.2% below the previous day's $81,274. A reader who had marked $80,000 watched it give way. Whether that old floor now caps rallies, only later candles will show.

A moving average is the average close over a set number of periods, and Nasdaq's glossary explains the rolling part: "As each new variable is included in calculating the average, the last variable of the series is deleted." CoinGecko's daily closes for 25 to 31 October 2026 were $80,049, $80,029, $80,801, $81,274, $77,839, $77,223 and $77,474. They add up to $554,689, and dividing by seven gives a 7-day average of $79,241.29. At 08:50 UTC on 2 November, Bitcoin sat $1,258.40, or 1.59%, below that line. Built from past closes, the line turns after price does.

How to Read Crypto Charts Step by Step

This routine for reading a crypto price chart works on any coin, shown here on Bitcoin.

1. Find the source. Block Insider's Bitcoin page charts CoinGecko data in 1D, 7D, 1M, 1Y and ALL views; for volume bars, use an exchange chart.
2. Start on daily candles. Read the last 30 days before any shorter view.
3. Read the latest candle. Note open, high, low and close, then compare body with wicks.
4. Compare volume with the previous week. Is the latest bar taller or shorter than the last seven?
5. Mark support and resistance. Draw a line where closes have turned more than once.
6. Add a moving average. Note how far above or below it price sits, in percent.
7. Switch to a log scale for long views. On a logarithmic scale, $10,000 to $20,000 and $60,000 to $120,000 take the same height, because both are 100% gains. On a linear scale the second looks six times taller.

What a Chart Cannot Tell You

A chart cannot tell you whether the trades behind it were real, and crypto has a record of inflated volume. Bitwise's SEC registration statement of 16 April 2019 said its index team screened more than 80 exchanges and found "ten exchanges that capture substantially all of the real, economically significant spot trading volume." A National Bureau of Economic Research working paper of 26 December 2022 found that wash trading on unregulated exchanges "averaged over 70% of the reported volume." Wash trading means trading with yourself to make a market look busy.

Small tokens carry a second risk. The CFTC's pump-and-dump advisory warns these schemes "can occur in thinly traded or new 'alternative' virtual currencies" and that "Once the pump begins, it can be over in a matter of minutes." A sudden green candle on a thin chart may be the pump. Block Insider's guide to spotting crypto scams covers other warning signs.

A chart also knows nothing about news. A hack, a court ruling, an exchange outage or one large holder selling can move price in minutes. Crypto chart patterns describe what traders did, and no pattern holds every time, so a crypto price chart is no forecast.

Is Trading Off a Chart Legal, and When Does Tax Apply?

Reading a chart and trading on it are legal in the United States, while faking the activity a chart displays is a crime. On 9 October 2024 the US Attorney's Office in Massachusetts announced charges against 18 individuals and entities over sham trades used "to create the appearance of trading activity that would make the tokens look like good investments." Acting US Attorney Joshua Levy said: "Wash trading has long been outlawed in the financial markets, and cryptocurrency is no exception."

Tax starts when you act on the chart. The IRS treats digital assets as property, and its digital assets page, last reviewed on 2 September 2026, says "you must report them whether or not they result in a taxable gain or loss." So a trader who closes 50 positions in a year has 50 sales to report, while someone who only learns how to read crypto charts and never trades has none.

Which Chart Setup Fits Which Reader

A first-time buyer holding for years needs daily candles and one moving average, checked weekly at most. Someone buying in pieces over a month gets more from 4-hour candles and volume bars, which help avoid buying into a thin spike. Active traders live on 15-minute and 1-hour charts, along with the tax paperwork. Anyone who has learned how to read crypto charts on Bitcoin should read a small token's volume with suspicion before its candles.
