Gains vs Ostium

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.

TVL from DefiLlama /protocol/{slug} currentChainTvls, excluding staking and pool2 categories. Market count from each venue's native API (same source as the perp-active-markets bench). The ratio reflects architectural choices, not absolute liquidity: a high ratio means the venue can list many markets cheaply, not that each market has deep liquidity. Compare with perp-volume-share for the liquidity angle.

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.

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.
