What it unlocks

For an agent

A breakout-detection agent scans the ADW-104 IOM each morning; when price_range_ratio (ATR-14 / ATR-252 baseline) exceeds 1.0 and the score is above 85 — the current reading is 91.9, at the 90th percentile of a 2,499-day history — it automatically generates entry-candidate alerts for momentum strategies and widens the bid-ask spread on the market-making side of the book to account for elevated intraday range risk. Source_lineage certifying the Stooq daily OHLCV input and methodology_version locking the True-Range pipeline let the compliance team verify the signal's data provenance in post-trade surveillance.

📈

For the business

A head of quantitative research uses ADW-104 to screen a multi-asset portfolio for assets whose near-term range is expanding well above the one-year baseline before committing to breakout trend-following positions. The current 91.9 score — near the top decile of all readings since July 2016 — tells the researcher that the SPY ATR-14 is running roughly 1.5x its 252-day baseline, a level historically associated with sustained directional moves rather than mean-reverting chop, allowing the team to justify wider profit targets and looser trailing stops without a custom vol-surface build.
