30Y at all-time high (flag)

What it is

30Y at all-time high (flag) — registry key us30y_at_all_time_high.

Boolean: is the trailing-one-month 30y high an all-time high in the DGS30 series? long-end supply-stress carrier, Phase 1 of improvements/long-end-stress.md; scoring deferred to a pre-registered study.

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

No validated skill horizon is on file for this metric — read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.

Source

Source module: fred_macro
Data source: computed

Derived metric — produced inside the platform (app/sources/fred_macro.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

1 when the trailing-one-month HIGH is an all-time high within the DGS30 history (no date STRICTLY BEFORE the trailing 21-observation window was at or above it), else 0; NULL when the history is unavailable. Companion flag that makes the us30y_years_since_higher all-time-high case machine-readable (its value is then the span from the first observation to the window-high date). Pure function years_since_window_high in app/sources/fred_macro.py.

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.

Release cadence

Recomputed each cycle from the full DGS30 history (FRED, lag 1).
