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.

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.
