Perp DEX charts

From 18 Sep 2026, from each exchange's own API, read every minute; a day is its figure at 00:00 UTC. Before that, daily volume is the sum of each exchange's daily candles (markets delisted since are missing), and open interest and TVL are DefiLlama's, the open interest scaled to the exchange's own figure.

A day carries a share only when every DEX with 1% or more of DEX volume now has a figure for it. Before the younger exchanges' histories start the total is too small and every share would read too high, so those days are left empty.

The taker fee both ways plus the order-book slippage of a market buy and a market sell of the size from the mid, on that day's median order book. Per exchange it is the median of its markets, weighted by each market's volume that day, with at least 3 markets; the fee is today's where its history is not known. With an asset picked, it is that asset's largest market on each exchange instead of the median.

The change in each pool's share price over 30 days (a pool without one gets a price built from its equity and profit, so deposits do not count as return), weighted by the pools' TVL. It is not annualised and it is not the exchange's own APR.

From DefiLlama, each exchange's perps listing only, so spot trading is not in them; DefiLlama revises past days and the whole series is read again every night. Hyperliquid's fees include its HIP-3 markets, which its volume here does not, so fees per volume reads high for it.

Combine the metric names (vol, oi, tvl, share, share_oi, mkts, vtvl, vret30, cost10k, cost100k, cost1m, fees, rev) with + − * / ^ and brackets, and the functions ma, sum, chg, lag, cum, abs, log, min and max. It is worked out per exchange and day, and a day with a missing figure stays a gap.
