How do you read a crypto price chart?
The same coin can look like a rocket or a wreck, depending on where the chart starts.
Before you believe any price chart, three quick checks will tell you whether it's showing you the story or selling you one.
Time range, chart type, scale
Each candle shows four prices for one period (open, high, low and close). Green closed higher than it opened; red closed lower.
Start with the time range. The same coin can look like it's soaring over a week and sinking over a year. KryptoKap's coin charts let you switch between 24 hours, 7 days, 30 days and a year.
Line charts join one price per period, usually the closing price. Candlestick charts show four prices for each period (open, high, low and close). A filled or red candle closed lower than it opened.
Look at the scale too. On a normal scale, a move from $1 to $2 looks tiny next to a move from $100 to $110, though the first doubled. A log scale shows equal percentage moves as equal heights, which suits long periods. Volume bars underneath show how much traded, which helps judge how meaningful a move was.
Reading one candle
A candle has a thick body from the open to the close and thin wicks to the high and low. A green body closed higher than it opened; a red one closed lower.
A long lower wick means the price fell during the period and was bought back up. A long upper wick means a rally faded before the close.
Three ways charts mislead
Cropping: starting a chart at a low makes any rise look dramatic. Scale: a linear chart over years makes early moves invisible and recent ones huge. Missing context: a chart of price alone hides whether supply grew at the same time.
Before believing a chart, check the start date, the axis and whether it shows price or market cap.
Linear and log, with numbers
Two tenfold years look completely different on a linear scale and identical on a log scale. Log shows equal percentage moves at equal height.
Take an example coin that went from $1 to $10 in its first year and from $10 to $100 in its second. Both years were a tenfold rise, a 900% gain. On a normal, linear scale, the first year rises by $9 and the second by $90, so the first year looks like a flat line hugging the bottom while the second looks like a cliff.
On a log scale, the gaps between $1 and $10 and between $10 and $100 are the same height, because each is a tenfold move. Both years now look identical, which matches what a holder actually experienced in percentage terms. A fall from $100 to $50 and a fall from $10 to $5 also look the same, since both are 50% drops.
Use linear for short periods, such as a day or a week, where the price range is narrow and dollar changes are easy to read. Switch to log for long histories, especially for coins that have risen many times over. Many charting sites put a small toggle, often labeled log or with a percentage sign, in a corner of the chart. If you can't tell which scale a chart uses, check the axis. Evenly spaced labels like 1, 10, 100, 1,000 mean log.
How candles combine across timeframes
A daily candle keeps only the first open, the last close, and the day's extreme high and low. The swings in between collapse into the wicks.
Every candle covers a chosen period, and longer candles are built from shorter ones. Four 6-hour candles make one daily candle. The daily open is the first candle's open, the daily close is the last candle's close, the high is the highest high of the four and the low is the lowest low.
Take an example day. The first 6-hour candle opens at $100 and closes at $102, the second runs from $102 to $106 with a high of $108, the third drops from $106 to $98 with a low of $95, and the fourth recovers from $98 to $101. The daily candle shows an open of $100, a high of $108, a low of $95 and a close of $101, which makes a small green body with long wicks both ways. The sharp sell-off and recovery inside the day are hidden apart from the wick.
That's why the same market can look calm on a daily chart and wild on an hourly one. Also check which time zone the chart uses to start each day. Crypto never closes, so one site's daily candle may run from midnight UTC while another runs from midnight in New York, and the opens and closes will differ slightly.
Key terms
Candlestick
A bar showing open, high, low and close for a period.
Log scale
Equal percentage moves take equal height.
Timeframe
The period each candle or point covers.
Volume bars
How much traded in each period.
Price is only part of the story
What happens next. Patterns that look obvious afterwards are much less obvious at the time.
Whether supply changed. A flat price chart can hide a growing supply and a rising market cap.
How much traded. Without the volume underneath, a dramatic move might rest on very little.
What people get wrong
A chart doesn't predict anything by itself. Patterns that look obvious afterwards are much less obvious at the time.
A steep line on a zoomed-in chart can be a small move. Always read the numbers on the axis.
Why it matters
Most price claims you see online come with a chart. Knowing how they can be framed helps you judge them.
Common questions
Which prices does KryptoKap use for its charts?
Daily closing prices from Coinbase's US dollar market for history, and Coinbase's live feed for the current price.
Should I use a line chart or a candlestick chart?
A line chart is easier for spotting the overall trend, especially over months or years. A candlestick chart adds the open, high and low for each period, which helps when you care how much the price swung within a day or week. Many people use lines for the big picture and candles up close.
