Definitions

In plain terms

It prevents a backtest from seeing later revisions, future members, or announcements that had not yet arrived.

Technical

Point-in-time integrity requires stable identities, valid or effective intervals, availability timestamps, revision lineage, deletion handling, and an explicit as-of query contract.

Scope

A dataset with historical dates is not automatically point-in-time correct.

Examples

  • A governed dataset records point-in-time dataset explicitly instead of inferring it from an ambiguous field.

Common misconceptions

  • Point-in-Time Dataset does not have one universal meaning without its stated market, source, and time context.
