Choose a reusable dataset or data interface for the period and research question you need. A personal trade-history screen or a chart alone does not establish a historical-data offering.
How to choose historical data
Define what you need to reconstruct
Decide which records and fields your analysis or replay requires, then inspect the provider’s actual coverage. A visual price history and a dataset you can reuse serve different purposes.
Inspect the data before relying on it
- Confirm coverage dates and any gaps within the required period.
- Read timestamp definitions so records can be placed on the intended timeline.
- Inspect schema and identifiers, not just a sample chart.
- Check export formats and whether the interface supports the records your analysis needs.
For a replay, select data that can represent the events you intend to reconstruct. For backtesting, assess historical coverage as part of the test design. An API can provide historical access, but the available period and fields must be checked for that route.
