What this data is and is not
These details are important for accurate backtests, replay pipelines, and microstructure features.
Funding applies to perpetual contracts; rows for other instruments carry mark and index prices without funding fields.
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.
