Definitions
In plain terms
It compresses many events into the first, maximum, minimum, and final eligible price observations in a bar.
Technical

Scope
Vendor daily OHLC fields and reconstructed intraday OHLC can follow different rules.
Examples
- A governed dataset records ohlc explicitly and preserves the source context needed to interpret it.
Common misconceptions
- OHLC does not have one universal meaning or policy without its declared source, scope, and data contract.
