Gamma Exposure (GEX) on Nifty
Gamma exposure (GEX) estimates how market-maker hedging may amplify or dampen Nifty moves around key strikes. It is one of the most searched quant concepts in Indian F&O — and one of the hardest to read without the right dashboard.
What is GEX (gamma exposure)?
GEX aggregates gamma across strikes to show where dealer hedging flows may pin price (positive gamma) or accelerate moves (negative gamma). Near ATM strikes, small spot moves can trigger large hedge adjustments.
twiQ displays gamma region, flip zone distance, key gamma strikes, and whether spot sits inside or outside the flip zone — so you know if the session may chop or run.
Gamma flip zone explained
The gamma flip zone is where net dealer gamma changes sign. Above or below it, hedging behaviour can shift. twiQ shows flip zone level, distance from spot in points and percent, and strike-level GEX contributions.
Positive gamma vs negative gamma sessions
Positive gamma environments often mean mean-reversion and pinning near strikes. Negative gamma can mean faster moves when hedgers chase spot. twiQ labels the regime and highlights strikes that may pin or speed up price.
FAQ
What is a gamma flip zone on Nifty?
It is the price region where aggregate dealer gamma crosses zero. twiQ plots this zone relative to spot and flags when you are inside it — a common setup for regime change intraday.
Is GEX useful for Bank Nifty too?
The concept applies to index options broadly. twiQ is built around Nifty 50 session structure; Bank Nifty traders use the same gamma/OI framework on their underlying.
