Stability is not directionality. A venue with persistently positive but tight-banded funding ranks better here than one that flips between positive and negative every settlement, even if the second venue offers better average carry. Read alongside perp-funding for direction and average level.

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.
