Everything you need to read
the options market
NeoGreeks gives Indian options traders a real-time edge — Dealer Gamma Exposure (GEX), zero-gamma levels, live OI chain, minute-by-minute OI flow, squeeze detection, and market regime signals, all in one terminal.
Gamma Exposure — see where hedging flows push the market
Large option desks are forced to buy and sell the index to hedge what they've written. GEX maps that forced flow strike-by-strike — walls where rallies stall, zones where drops accelerate, and the regime that tells you whether today rewards range-trading or momentum.
NIFTY · Live GEX Profile
Call & Put Walls
The strikes with the heaviest hedging pressure. Rallies tend to stall into the call wall; a break below the put wall tends to run fast. Your ceiling and floor for the session, recalculated live.
Zero-Gamma Level
The tipping point between two markets: above it, hedging damps moves (range days); below it, hedging amplifies them (trend days). Crossing it is often when a quiet session turns violent.
Gamma Regime
LONG GAMMA: fade extremes, sell premium, expect pinning. SHORT GAMMA: ride momentum, widen stops, don't trust dip-buying. One badge sets your playbook for the day.
Plain-English Guidance
Every chart ships with speed-bumps-and-slippery-slopes explanations built in — institutional analytics without the institutional jargon. Available for NIFTY, BANKNIFTY and SENSEX.
Live OI chain with 1-minute resolution
Every strike. Every second. See exactly where call and put writers are positioned — and watch it change in real time.

Minute-by-minute OI Flow
Track OI additions and unwinding at every strike across four rolling windows — 5 min, 15 min, 30 min, and 60 min — on a single chart.
PCR Gauge & Trend Bias
Put-Call Ratio calculated live from raw OI. Quickly see whether the market is bullish, bearish, or in a compression zone heading for a breakout.
Know before the move happens
NeoGreeks monitors price velocity and OI imbalance simultaneously to surface squeeze setups and sudden directional breaks before they fully develop.
Squeeze & Velocity Detector
Fires when price moves beyond a configurable threshold (e.g. 35 pts on NIFTY, 100 pts on SENSEX) within a 2-minute window. Paired with OI compression at ATM ± 2 strikes for directional confirmation.
Price velocity trigger — configurable per instrument- OI compression detection at ATM ± 2 strikes
- Lopsided OI ratio → directional lean signal
OI Buildup Alerts
Configurable threshold alerts when raw OI change at any single strike crosses your defined size. Catch institutional positioning as it happens, not after the move.
- Per-strike OI buildup threshold (default 25,000 lots)
- Rolling delta across 5 / 15 / 30 / 60-min windows
- Support & resistance identified from OI clusters
