# Early-warning indicator history

Package `ewi-history` · version 2026-10-28 · 734 rows · 2026-09-08 to 2026-10-28

## What it is

The Dashboard's sixteen early-warning indicators, one row per indicator per day: status colour, the numeric reading where the indicator has one, and the day's overall escalation level.

## Source and tier

Computed by the firm's collectors from the public feeds the Dashboard reads (IMF PortWatch, Yahoo Finance, FRED, USGS, OFAC). Tier T2 (computed) on the firm's source tier policy (T1 government and regulatory, T2 institutional, T3 reputable media, T4 structured data).

## Cadence

Daily, from the first collector run after 8 September 2026. Nothing is backfilled.

## Fields

| Field | Meaning |
|---|---|
| `date` | ISO date. |
| `indicator` | Indicator id, EWI#1 to EWI#16. |
| `tab` | Dashboard tab the indicator belongs to. |
| `status` | GREEN, AMBER, RED or GRAY (no live source). |
| `reading` | The numeric part of the reading, blank when GRAY. |
| `score` | 0 green, 1 amber, 2 red; blank when GRAY. |
| `escalation_level` | The day's overall level, the highest non-gray status. |

## Caveats

Thresholds are the firm's, per the AEGEAN-OS M9 model, and may be revised; a revision changes future rows only. GRAY indicators have no live source and are recorded so the coverage gap is visible.
