Definitions
In plain terms
As each new observation arrives, the oldest eligible one can leave and a new high or low can enter.
Technical

Scope

Examples
- A Fintech Builder lesson can compute or identify Rolling Extreme only after declaring its inputs, timing, and edge-case rules.
Common misconceptions
