Kalshi order book history
Kalshi’s API gives the current order book. Historical order book depth needs to be recorded over time, by you or by a data provider.
Options
- Record snapshots yourself on a schedule and store them.
- Use trade history where depth is not needed.
- Use a provider that already records books, and check its snapshot frequency and gaps.
