Perpetual futures contracts are a type of derivative that allows traders to speculate on the price of digital assets without an expiration date. The Futures Volume Intraday Perpetual metric measures the total trading volume (in USD value) of perpetual futures contracts within a specific intraday time frame, focusing on the native asset against USD-related currencies (both fiat and stablecoins). This metric is useful for assessing short-term market activity and liquidity in the perpetual futures market. For example, you might ask, "What is the total trading volume for Ethereum perpetual futures in the last hour?". Note: Buy and sell volumes do not always sum up to the total volume, as in rare cases, certain transactions cannot be definitively classified as either buys or sells.

This is the Point-in-Time (PiT) variant of Futures Volume Perpetual. 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.
