Rolling Support and Resistance

What prior-only extrema bound the next observation? Walk the evidence clock one stage at a time. This lab teaches the publication contract; it does not simulate returns, platform parity, or trade performance.

Selected expression

support_t=min(L_(t-n..t-1)); resistance_t=max(H_(t-n..t-1)) for a causal exclusion convention

Availability rule

A level derived from a prior session becomes available only after that source session is final; a confirmed pivot becomes available only after its declared confirmation lag.

Verified synthetic fixture

This lab is paired with datasets/implementation-fixtures.json: 96 deterministic, oldest-to-newest observations spanning oscillating, rising, and moderating regimes. It is teaching data—not market history or predictive evidence.
