Definitions

In plain terms

For a length-n SMA, the first full-window output normally appears at the nth valid observation.

Technical

The policy fixes valid-observation counting, missing values, session gaps, window endpoints, and whether partial outputs are prohibited.

Scope

Readiness is not the same as numerical stability after warm-up.

Examples

  • A governed lesson uses Full-Window Readiness only with declared inputs, timing, parameters, and edge-case behavior.

Common misconceptions

  • Readiness is not the same as numerical stability after warm-up.
