Find Gamma Exposure Levels

To find gamma exposure levels for an Indian index, open the GEX dashboard: it shows GEX by strike with the gamma flip, the call wall and the put wall marked, and how net GEX changed over the last 5 and 15 minutes. GEX is an estimate of how much delta hedging option dealers would need to do as the index moves, in ₹ crore per 1% move.

  2. Choose the index from the tabs at the top.
  3. Pick a strike range: Auto range, ATM ±10, ±20 or ±30.
  4. Switch between Nearest and All expiries.
  5. Switch the bar chart between Net, Call vs Put and Table.
  6. Read the flip and walls in the cards, and their distance from spot.
  7. To study a past day, sign in, switch from Live to Historical, choose a session and step through it minute by minute.

What to look at​

  • Net GEX and the regime badge. Strong Long Gamma, Long Gamma, Flip Zone, Short Gamma or Strong Short Gamma, from net GEX as a share of total |GEX|.
  • Gamma Flip (marked est.). The index level where net GEX changes sign, shown as a band: the range it moves to when implied volatility is shifted and tilted by 10%.
  • Walls. The call wall is the strike above spot with the largest call GEX; the put wall is the strike below spot with the largest put GEX.
  • ΔGEX Momentum. The change in net GEX over 5 minutes, with the 15-minute and full-day change below it.
  • Spot vs Gamma Flip. How the flip moved through the session and how many minutes spot spent above and below it.
  • The dealer-sign assumption. Calls count as positive gamma and puts as negative, the US convention. NSE publishes no trade-side data, so this cannot be checked for India. If the real positioning is the other way round, every bar and the flip level invert.
  • Near expiry. A note warns that gamma is bunched at the ATM strike.
  • GEX dashboard: how GEX is calculated and every view on the page.
  • Intraday charts: GEX by strike or net GEX over time inside Sheets.
  • Max pain: another open-interest reading for the same expiry.
