The closing price of BTC in USD. Prices are aggregated from both centralised and decentralised exchanges. Prices are calculated using a VWAP-like methodology where outlier detection is applied to mitigate the impact of erroneous or anomalous trades on the final composite price. Data is available with up to 10-minute resolution and usually arrives with 3-minute latency once the interval has ended.

Prices may occasionally change as late-reported data from individual exchanges is incorporated. However, strictly immutable data points are available in the PIT (point-in-time) version of this metric.

This is the Point-in-Time (PiT) variant of Price. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
