About this app

See what the market's biggest hidden players did today.

Every trading day, Dark Pool Monitor distills two of the most-watched institutional indicators into one clean readout:

- DIX, the dark pool buying ratio: hidden off-exchange buying pressure across the S&P 500. High readings have historically clustered around accumulation phases.
- GEX, dealer gamma exposure: how strongly options dealers dampen or amplify market moves to stay hedged, a key driver of volatility regimes.

WHAT YOU GET
- Today's DIX and GEX with 15 years of percentile context
- Market regime classification (accumulation, distribution, squeeze conditions)
- Bottom-near / top-near probability gauges from a model validated out-of-sample
- Nearest-analog readout: how the market behaved after the most similar historical days
- Price and volatility trend axes
- DIX sparkline over the last 180 trading days
- Updates automatically every trading day

WHO IT'S FOR
Swing traders, options traders, and long-term investors who want institutional context behind the day's price action, without paying hundreds per month for a professional dashboard.

HONEST BY DESIGN
All probabilities are historical statistics shown with their validation scores. Past behavior does not guarantee future results. Nothing in this app is investment advice.

Data: FINRA off-exchange volume and public market data, processed daily by an automated pipeline.
See where institutions are quietly buying, every market day.
