Live Gamma Exposure (GEX) Dashboards

Gamma exposure estimates how much delta hedging option dealers must do as the index moves. Positive GEX means dealers sell rallies and buy dips, compressing ranges; negative GEX means they chase price, expanding them. Every dashboard below is free and updates through the session — no login.

  • Nifty 50 GEXNSE

    The deepest options book in India. Gamma flip, call and put walls, and intraday ΔGEX for the weekly expiry.

  • Bank Nifty GEXNSE

    Higher gamma density and wider strikes than Nifty — dealer hedging flows move it faster around the walls.

  • Sensex GEXBSE

    BSE flagship index. Watch the flip level on expiry day, when positioning concentrates into few strikes.

  • FinNifty GEXNSE

    Financial services index. Thinner book, so single large strikes dominate the gamma profile.

  • Midcap Nifty GEXNSE

    Midcap index with a 25-point strike gap — walls sit closer together than the large-cap indices.

  • Bankex GEXBSE

    BSE banking index. Useful as a cross-check against Bank Nifty positioning on the same sector.

How to read these dashboards

Net GEX
Dealer delta-hedge notional per 1% index move, in ₹ crore. Large positive values mark long-gamma, mean-reverting conditions; negative values mark short-gamma, trending conditions.
Gamma flip
The index level where aggregate dealer gamma changes sign. Above it, hedging tends to stabilise price; below it, hedging amplifies moves.
Call wall / put wall
The strikes carrying the most call and put gamma. They often behave as resistance and support, and act as expiry-pinning magnets — moves beyond them can accelerate as hedges unwind.

GEX describes expected volatility behaviour, not direction — it is not a buy or sell signal. Read it alongside open interest, India VIX and the live straddle chart. Data is indicative and not investment advice.
