A dark pool is a private exchange where institutional investors trade large blocks of shares away from public markets. This helps minimize market impact and hide their trading intentions. About 15-18% of US equity volume trades through dark pools.
DIX (Dark Index) measures dark pool short volume as a percentage of total dark volume. High DIX (>0.50) is counterintuitively bullish - it indicates market makers are shorting to accommodate buyer demand (smart money buying).
GEX (Gamma Exposure) shows market maker gamma exposure from options. Positive GEX means they'll dampen moves (buy dips, sell rallies). Negative GEX means they'll amplify moves (buy rallies, sell dips).

When smart money buys in dark pools, market makers must short to them. High short volume = high buyer demand being accommodated. It's the opposite of public market short selling interpretation.
When DIX moves opposite to price. Bullish divergence: price falling but DIX rising (smart money buying the dip). Bearish divergence: price rising but DIX falling. Divergences often precede reversals.
The price where net gamma exposure crosses zero. Above flip = positive GEX (mean reversion expected). Below flip = negative GEX (trending expected). Major support/resistance level.
Look for multiple large prints (10K+ shares) at ask price over several days. Cumulative buying pattern indicates institutional position building.
DIX provides direction, GEX provides volatility context. High DIX + positive GEX = bullish, expect low vol. High DIX + negative GEX = bullish, expect potentially volatile move.
DIX is a multi-day to multi-week indicator. Not for day trading. Best for swing trades and position adjustments over 5-20 day periods.
For each strike: GEX = gamma × OI × 100 × spot price. Calls where dealers are short contribute negative gamma (they sold calls). Sum across all strikes and expirations for total GEX.
Price tendency to gravitate toward high open interest strikes at expiration. Caused by market maker gamma hedging. Creates mechanical flows that pin price near strikes.
Use features (DIX level, trend, divergence, GEX) to predict forward returns. Train with walk-forward validation. Expect multi-day holding periods. Focus on extreme readings.
The maximum capital before market impact degrades returns. Test by backtesting at different sizes. Dark pool signals typically have moderate capacity due to underlying liquidity.
Use daily DIX/GEX for overall direction and environment. Use real-time prints for entry timing and confirmation. Best trades have alignment across both timeframes.
