Volume/OI Ratio

Rolling volume-to-open-interest ratio per exchange over a configurable date range and smoothing window. The ratio signals whether a market is in an active trading regime (high ratio) or an accumulation/positioning phase (low ratio). Use it to build a multi-exchange OI efficiency chart, detect regime shifts, or filter exchanges by relative trading intensity.

Authentication

Requires Dev tier or higher. Dev: up to 30 days, window_days ≤ 7. Pro: up to 365 days, any window_days value. Requests beyond your tier's limits are clamped.
