Reading a crypto price chart: candles, volume and timeframes
How to read candlesticks, volume bars and timeframes, when to switch between linear and log scale, and what a chart can never tell you.

In short
- A candlestick shows the open, high, low and close for one time period. The body shows where price opened and closed; the wicks show how far it moved in between.
- Volume shows how much was traded in each period, which helps you judge whether a move happened with broad participation or only a few trades.
- Charts describe what has happened. They do not predict what must happen next, however neat the pattern looks afterwards.
Start with the candle itself
Most crypto charts use candlesticks. Each candle summarises one period of trading: one minute, one hour, one day or whatever timeframe you choose. The top and bottom of the thin line, usually called the wick, mark the highest and lowest trade in that period. The thicker body marks where the period opened and where it closed.
If the close is above the open, charting apps usually colour the body green or white. If the close is below the open, they use red or black. That colour is only a quick visual cue. The important point is that one candle is just a compressed record of four prices: open, high, low and close.
What volume adds
Under the price chart you will often see volume bars. They show how much of the asset traded during the same period as each candle. A sharp move on strong volume usually means many people took part. A sharp move on weak volume can mean only a few orders pushed the market around, which is common in thin coins.
Volume does not tell you whether the buyers or sellers were “right”. It does help you judge whether a move was broad and active or narrow and fragile. That matters when you are deciding how much trust to place in a breakout or a sudden collapse.
Timeframes change the story
A 5-minute chart and a 1-week chart can both be true and still look completely different. Short timeframes show noise, quick reactions and the details of a single trading session. Longer timeframes smooth that out and show whether the market has really changed direction over weeks or months.
A useful habit is to start wider, then zoom in. Look at the daily or weekly view to understand the broader range first, then switch to the hourly or 15-minute view only if you need a more precise entry or exit. Starting too close can make an ordinary move look far more dramatic than it is.
Linear and log scale are for different questions
A linear chart uses equal vertical space for equal price moves. The gap from $10 to $20 is the same height as the gap from $100 to $110. That is fine for short periods or narrow ranges.
A log chart uses equal vertical space for equal percentage moves. The move from $10 to $20, which is +100%, takes the same height as $100 to $200, also +100%. For assets that have risen or fallen by large multiples over years, log scale often gives a fairer picture of the trend because percentage change matters more than absolute dollars.
What charts can help you do
- See the current price in context rather than as an isolated number.
- Check whether the market is moving with strong or weak volume.
- Compare how volatile a coin is over minutes, days and months.
- Spot whether today's move is exceptional or ordinary for that asset.
What charts cannot tell you
A chart cannot tell you why a move happened unless you already know the news, the supply schedule, the liquidity and the market positioning behind it. It cannot tell you what the next candle must do. Patterns that look obvious afterwards often looked ambiguous in real time.
Use the chart alongside the markets page, gainers and losers and the broader discussion in what moves crypto prices. Read it as a map of where price has been, not as a promise about where it is going.
