Definitions

In plain terms

Aroon converts separate high and low recency counts into comparable zero-to-100 scores.

Technical

Scope

Recent extremes do not state how large the price move was.

Examples

  • A governed lesson calculates or identifies Extreme Recency only after its parameters, state, timing, and edge cases are declared.

Common misconceptions

  • Recent extremes do not state how large the price move was.
