Counts reflect each venue's live market catalog at query time, mainnet only. The asset class comes from the venue's own metadata where it publishes one; Hyperliquid HIP-3 dexes and dYdX publish none, so their symbols are matched against the crypto markets the other venues list and a fixed table of forex, commodity and index names. Tokenized gold (PAXG, XAUT) is a crypto token and is not counted. A market counts once whether it trades 24/7 or only during exchange hours.
Perp DEX price to fees: what the market pays per dollar of trading fees

P/F = circulating market cap (CoinGecko) / annualized fees (DeFiLlama dailyFees, trailing 30d x 365/30), on the DeFiLlama parent the token accrues from. Fees include the share paid to liquidity providers; P/S uses protocol revenue only. Low-float tokens show a much higher FDV/F than P/F. Pre-TGE venues are listed unranked with fees and OI, no ratio. A low multiple is not a recommendation.

Volume is self-reported by each venue's public data surface and counted per UTC day, one side of each trade. Perimeters differ slightly per venue and are stated in the ledger notes. A closed day can be restated by a venue for one to two days; the harness re-reads the last three days every hour. Not a measure of organic flow: incentive programs and wash trading inflate notional on every venue.

Volume / OI (24h)
Extendedn/aGMXn/a
The ratio is a screen, not a verdict. Both terms are the venue's own figures (24h volume and open interest as each API reports them, in USD), so a venue that counts both legs of a fill moves its ratio without changing anything real. A very low ratio (Ostium, 0.2x) means positions held for days on thin daily volume; a very high one (Kalshi, above 40x) means a day of trading dwarfs what stays open. The bands in the methodology say what each range usually means.

How this pair was selected
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
