Member fresh 5d-low share

What it is

Member fresh 5d-low share — registry key member_fresh_low_share.

Carrier for the complacency_break member_erosion CONTEXT leg (CB-1b, 2026-06-10) — the fraction (0-1) of the screener universe (universe_price_daily tickers with >= 6 rows) whose latest close is a fresh 5-day closing low. The June-02 blind-spot tell (members cracking under a calm index). Pure data carrier — no classification bands, no health-score contribution. MECHANISM-GRADE context: the member_erosion leg it feeds escalates the calm-lane state quiet->elevated but NEVER produces high; the forward card grades it. Computed at capture from universe_price_daily (same signals.db).

Data-pyramid tier

T1 — Signal. This metric sits at the signal layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.

Horizon & validation

Horizon: 1-3d — the window this metric’s measured skill speaks to. A horizon stamp is an evidence claim, not a trading signal.

Evidence: Calm-lane member-erosion CONTEXT carrier (CB-1b, 2026-06-10) — the share of the screener universe at a fresh 5d closing low. The June-02 blind-spot tell (members cracking under a calm index: legA/legB both quiet that day). MECHANISM-GRADE CONTEXT ONLY — extreme at both 2026 setups (May-13 45.6%, Jun-01 40.8% at the index high) but the gated cuts are weak (>=20%: 1.36x) on a ~1y substrate, so it FAILS statistical-confirmation and is included on mechanism + cost-asymmetry grounds only: it escalates quiet->elevated, NEVER high. NO backtest graduation — the forward card grades it. Source: research/findings/DDX_complacency_breaks_2026-06-10.md (Round 2, “900-name member fresh-5d-low share”). Amplification context, never direction.

Source

Source module: capture
Data source: computed

Derived metric — produced inside the platform (app/signals/capture.py or equivalent) rather than fetched as a raw upstream value. See the How it's computed section below for the formula.

How it’s computed

Over universe_price_daily, for every ticker with >= 6 rows take its 5 most-recent closing prices; a ticker is a FRESH 5-DAY LOW when its latest close is the minimum of those 5 closes. member_fresh_low_share = (# fresh-5d-low tickers) / (# eligible tickers with >= 6 rows), a fraction in [0, 1]. NULL when the universe table is empty / unreadable (the member_erosion leg then abstains). See app/signals/capture.py:_resolve_member_fresh_low_share.

Where it surfaces

Health-score / alignment role

Data carrier — no implication, no health-score contribution.

Persisted for downstream consumers (sparklines, base-rate matcher, calibration substrate) but does not classify into BULLISH / NEUTRAL / BEARISH and does not contribute to the 0-100 health score.
