Caveats

What this data is and is not

These details are important for accurate backtests, replay pipelines, and microstructure features.

Open interest is a periodic snapshot published by each exchange, not a continuous event stream; snapshot cadence varies by venue.

Values are reported in contracts and in quote notional where the exchange provides both.

This page starts on 2025-06-28 based on the earliest stored hourly files for its covered exchange IDs and grows as new hourly files are published.
