GEX (gamma exposure) measures the rate of change of dealer hedging flows — it tells you how much dealers will buy or sell for each 1% move in NIFTY. DEX (delta exposure) measures the current absolute directional position of dealers — it tells you the total long or short bias right now. GEX predicts the magnitude of hedging activity; DEX reveals the current directional tilt. Together they give a complete picture of dealer positioning in NIFTY options.
