NIFTY Gamma Exposure (GEX) | Live GEX Profile
Gamma Exposure (GEX) measures how much NIFTY dealers must hedge as the index moves. Positive GEX (long-gamma regime) typically pins the spot and dampens volatility, while negative GEX (short-gamma regime) accelerates moves. Our tool plots GEX per strike with Call Wall and Put Wall levels — the most actionable map of where dealer hedging will support or resist price.
The chart shows Net GEX bars per strike (green above zero where dealers stabilize, red below where they accelerate moves) with the ABS GEX line tracing total hedging concentration. Use the time slider to scrub any minute of the session in both live and historical modes.
Nifty 50 (NIFTY) Gamma Exposure: How Dealer Hedging Drives Price
What is NIFTY Gamma Exposure?
Gamma Exposure (GEX) measures how much option market makers must hedge in Nifty 50 as the underlying moves. As a major Broad Market index on NSE, dealer hedging flows in NIFTY are large enough to dominate intraday price action. Positive net GEX means dealers stabilize price (sell rallies, buy dips). Negative net GEX means dealers amplify trends (buy rallies, sell dips).
Why GEX matters for NIFTY traders
When Nifty 50 sits in a positive-GEX regime, intraday ranges compress and breakouts fail — perfect for premium-selling strategies. When net GEX flips negative, expect wider candles and trending moves — better for directional buyers. Watching the GEX bars in real time gives NIFTY traders an edge that price alone doesn't.
Reading the NIFTY Gamma Exposure chart
Green bars above zero are strikes where dealers are net long gamma — they dampen volatility. Red bars below zero are strikes where dealers are net short gamma — they accelerate moves. The blue ABS GEX line traces total hedging concentration. Spikes mark the most actionable strikes.

Nifty 50 (NIFTY) GEX Calculation: From Greeks to Dealer Hedging
The NIFTY GEX formula
Per strike, GEX = Spot² × Gamma × Open Interest. Calls add to GEX (dealers assumed long), puts subtract (dealers assumed short). Summing across the Nifty 50 option chain yields the aggregate dealer gamma exposure — the size of the rebalancing flow that has to happen for every 1-point spot move.
Why we use Spot² in NIFTY GEX
Gamma is a per-unit-of-spot quantity. Multiplying by spot once converts to delta-per-1-point. Multiplying again converts to delta-per-1-percent move — the standard convention used by SpotGamma, Perfiliev, and most academic literature. Our NIFTY numbers use the same formula expressed in crores.
Why our NIFTY numbers differ from US GEX dashboards
We omit the US 100-contract multiplier and express in Rs ÷ 10⁷ (crores). The formula, sign convention, walls, and regime direction are all identical. Only the absolute magnitudes scale differently. Proportional bar heights and rankings match international tools exactly.
Trusting the math as of 12 June 2026
The Nifty 50 GEX you see today is the same standard formula tested across decades of dealer-flow research. Walls and regime calls translate cleanly to action on NIFTY.
How to read the Gamma Exposure chart
- Check the regime (Net GEX sign) — Positive Net GEX = long-gamma regime (pinning/mean-reversion). Negative = short-gamma regime (trending). The colour of the Net GEX number tells you immediately.
- Identify the Call Wall and Put Wall — Toggle Show Walls in settings. Call Wall is the upside ceiling, Put Wall is the downside floor. Spot tends to oscillate between them on positive-GEX sessions.
- Read the per-strike bars — Green bars above zero are strikes where dealers stabilize price (positive Net GEX). Red bars below zero are strikes where dealers amplify moves.
- Use the ABS GEX line — The blue overlay traces total gamma concentration. Spikes mark the most actionable strikes — where dealer hedging flows are largest.
- Scrub the time slider for context — Drag the slider backward to see how walls migrated through the day. A rising Call Wall + rising spot = sustained bullish bias. A falling Put Wall + falling spot = breakdown risk.
