Dark Pool Monitor

Dark Pool Monitor shows you what most retail tools don't: how much trading is happening off-exchange, in the dark pools where institutions move size quietly.

Every trading day it computes two professional-grade signals from primary data.

DIX (Dark Index): the share of S&P 500 volume executed on dark pools, dollar-weighted. A high DIX means heavy hidden buying; a low DIX means the opposite.

GEX (Gamma Exposure): options dealer positioning that signals whether market makers are dampening volatility or amplifying it.

WHAT YOU GET

• A clean daily dashboard for the S&P 500: DIX, GEX, price, and a plain-English regime read (accumulation vs distribution).
• A 180-day history chart so you see the trend, not just today.
• Search 2,000+ individual stocks for their own dark-pool ratio and trend.
• A Market Map that ranks names by unusual accumulation and distribution.
• A regime and nearest-analog readout that compares today to similar past setups.

HONEST BY DESIGN Built by a developer who trades, from free primary sources (FINRA short-volume data and market prices). It is informational, not financial advice, and not a timing system. Our own backtests showed dark-pool accumulation did not beat buy-and-hold as a timing signal, so we present it as context, not a crystal ball.

Data updates automatically every trading day after the close.

Pro unlocks the full dashboard, history, per-stock search, and the Market Map. Try it free for a week.
