Crypto Futures Volume

Compare reported 24-hour perpetual-futures notional across major CEX and DEX venues, with source status, collection time, active-pair counts, and top symbols.

What 24h Futures Volume Measures

Futures volume is the reported notional value of contracts traded during a venue’s rolling 24-hour window. It is turnover, not deposited collateral and not open interest. More volume can support liquidity, but it does not by itself prove tighter spreads or better execution.

This tool reads public perpetual-futures ticker endpoints directly. It sums successful venue responses, labels partial or cached states, and shows PerpFinder collection time. Venue window definitions and upstream timing can differ.

Definition and methodology

This page sums each successful venue endpoint's reported 24-hour perpetual-futures notional. Notional is the contract value traded, not collateral deposited and not open interest. Volume measures completed turnover; open interest measures positions that remain outstanding.

Data comes directly from public venue ticker endpoints. Quote-volume fields are normalized to one-sided USD notional, then summed by venue. A failed venue is omitted and the response is marked partial; if a critical venue fails, the API may serve the last cached snapshot. The browser checks every two minutes, the server keeps a ten-minute process cache, and shared responses may be cached for up to fifteen minutes. The volume data timestamp records collection time, not a synchronized upstream trade time.

Venue APIs do not all define rolling windows, contract conversions, or delayed corrections identically. Volume is useful context, but it is not proof of book depth, execution quality, or venue honesty. Read the normalized-volume methodology and data definitions, then compare fees, active perp venues, and venue-level review context.
