DIX

What it is

DIX — registry key dix.

Classifier metric. See the bands table below for the band-by-band reading.

Source

Source module: darkpool
Data source: back_fillable

Fetched directly from app/sources/darkpool.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

Raw Dark Index value from the SqueezMetrics daily CSV (https://squeezemetrics.com/monitor/static/DIX.csv). DIX is the dollar-weighted short-volume fraction across NYSE/Nasdaq lit + dark venues, reported as a decimal in roughly [0.35, 0.55]; higher = more buying pressure under the surface. Daily cadence — the CSV updates after the previous session’s settle. See app/sources/darkpool.py:27 (_fetch_dix_gex). The classifier bands (Strong buying / Moderate buying / Neutral / Weak / Selling pressure) are applied downstream via signal_defs.band_for('dix', value).

Where it surfaces

Surface: daily_signals row (daily-cadence persistence)
Surface: intraday_signals row (per-cycle snapshot)

Bands / thresholds

Health-score / alignment role

Health score component: dix (weight + math in app/signals/config/score_weights.json and app/signals/score.py).
Alignment category: dark_pool, default weight 1.5 (see /kb/alignment for the 11-category framework).
Contributes to: health_score.DIX, implication.dark_pool, alignment.dark_pool, cascade.3

Release cadence

Publishes: daily
Approximate time (ET): 16:30
Lag days: 0

_SqueezeMetrics DIX.csv is an EOD publication around 16:30 ET; during the live session the most recent row is the prior close. Mapped to freshness_class=prior_close by routes.PUBLISH_TO_FRESHNESS_CLASS.
