Iteration 07 — `bar_fisher_shannon` WATCH

Olivares, Plastino & Rosso 2012 · rolling 200-bar window · updated 2026-06-02 04:53 UTC

1 · Context of work

Candidate

bar_fisher_shannon (custom)

Frozen test constants

m=3 · tau=1 · ordering=lexicographic

Axis-2 status

defensible — FIM is order-sensitive — lexicographic pattern ordering is a fixed 3rd constant.

Window

rolling 200 bar closes (project-wide LOOKBACK)

Matrix version

CH_FEATURE_BANLIST.md @ d74f75e1 · FRAMEWORK.md Axis-1 (|ρ|≤0.85, R²≤0.85, h_norm≥0.05)

Gate: PASS = |ρ|≤0.85 AND R²≤0.85 AND h_norm≥0.05 across every valid bar set. Not yet fully grounded — see verdict pill.

Most frequent worst competitors:

duration_us — appeared as worst competitor in 34 cell(s)
trade_intensity — appeared as worst competitor in 30 cell(s)
close — appeared as worst competitor in 25 cell(s)

3 · Next steps

Iteration 8: bar_spectral_entropy (tested at sf=1.0 · method=fft · normalize=True).

4 · Pending tasks

3 bar set(s) skipped (insufficient bars / empty cell).
Axis-2 final status deferred to Stage 2 (project-wide constant ratification, after the full family is evaluated).
Cross-candidate ρ/LOO-R² matrix (run_cross_candidate.py) must run before any PROMOTE — catches sibling clusters.
