SI comparison scope and payment direction
This page retains low-turnover SI contracts without the main ranking’s $1M threshold. Positive funding is paid by longs; negative funding is paid by shorts. High and low are rate values, not recommendations. Annualisation method · Official sources.
Rates and chart methodology
Annualised over the window sums what actually settled on that contract, then extrapolates across the hours those settlements covered — it is not today's rate projected forward. A contract listed less than 30 days ago is extrapolated from its own span. The grey line is zero: above it longs pay, below it shorts pay. Every row in that column shares one vertical scale, so their swings can be compared directly.
