D07-F07-A10 · LEVEL 2 GUIDED LAB · SYNTHETIC DATA

Dynamic Zone Bands

How can empirical rolling quantiles replace fixed oscillator thresholds? 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

package convention: lower=rolling quantile_q(X); upper=rolling quantile_(1-q)(X)

Availability rule

An output at t may use only finite, basis-consistent observations available through t; chart alignment never moves the information clock backward.

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.
