I want to be able to query historical odds at specific timestamps (e.g., 72h, 24h, 12h, 6h, 3h, and 1h before kickoff) for a bookmaker overround comparison project. Currently, only closing odds are available, but I need a time-series of snapshots to calculate overrounds at specific points before the event starts. This is important for analyzing how bookmaker margins change leading up to kickoff.
