Start with identity, units and time

Check the asset’s name and type, its currency and, for an exchange listing, its market. A similar symbol does not establish the same instrument. Distinguish the observation’s source time from the time you loaded the page: reopening an older quote does not create a new trade.

An exchange pair and an aggregate price

For twenty selected cryptocurrencies, the main price view is a live Binance pair quoted in USDT. CoinGecko’s aggregate USD data remains separate. If an asset has no live pair in this selection, read the source actually stated beside its price; another exchange or quote currency is not substituted.

What one candle records

An exchange candle records the open, high, low and close of the chosen interval. Its timestamp is in UTC and volume measures units of that cryptocurrency traded in the same interval. The latest unfinished candle can change. The full chart range and the length of one candle are different settings.

CoinGecko’s separate history uses its own sampling and USD observations. Its rolling 24-hour volume is not the volume of one exchange candle. Likewise, overview seven-day points without individual timestamps do not establish minute-by-minute history. Match the source, quote currency and period before comparing observations.

Read a curve and a percentage in context

Compare matching periods and check whether the chart contains dated points, completed daily closes or only source ordering. These views have different meanings. A price change does not automatically include dividends, staking rewards, currency conversion or the costs of a particular investor.

A dash marks an unavailable value rather than zero. During a source outage, read the stated status and the timestamp of any last-known observation. Missing history cannot establish a stable price, and a movement alone does not prove its cause.
