Stock GEXScreener
Net dealer gamma exposure for every F&O stock, live through the session — short-gamma names, walls, pins and each name's intraday gamma trend.
What the Stock GEX Screener shows
Net dealer gamma exposure for every NSE F&O stock — roughly 200 names — live through the session: the whole universe is re-scanned every half hour and the most active names every five minutes, and the table refreshes itself as each scan lands. Index GEX tells you about NIFTY's tape; this screener finds the individual stocks where option positioning is large enough to shape the share price itself: short-gamma names where hedging amplifies moves, pinned names sitting between heavy call and put walls, and how each name's gamma has moved since the morning. Click any row to open that stock's live cockpit.
How to read it
- Net GEX / Net ratio — the sign and size of dealer gamma per stock, with the ratio normalising for contract size so large and small names compare fairly.
- Today — a sparkline of the name's net GEX across today's scans — is the book building or emptying — with the change since the first scan.
- Short-gamma names — stocks where dealers must chase price to stay hedged — moves in these names tend to extend rather than fade, which is exactly what a breakout trader wants to know.
- Call wall / Put wall — each stock's heaviest strikes above and below spot. Approaches to a wall often stall; clearing one removes the brake.
- Pin — the strike pulling price and how convinced the book is (forming, weak, stable, locked) — a stock locked on a strike into expiry is a pin candidate.
- Scan cadence — the universe every half hour from 09:20 and the hot set (largest gamma, near a wall, or being watched) every five minutes; rows that just refreshed flash briefly.
- Open the cockpit — click a row: Dealer Positioning opens for that stock and puts it on the one-minute live collector, so its levels update every minute while you watch.
Frequently asked questions
Dealers hedging a short-gamma book must buy as the stock rises and sell as it falls, adding fuel to whatever the stock is already doing. Short-gamma names therefore tend to trend harder and whipsaw faster than their long-gamma peers.
The mechanics are identical, but stock chains are thinner, strikes are wider and positioning is lumpier — so a single large strike matters more, and the data comes from periodic scans rather than a per-minute feed. Treat stock GEX levels as zones, not lines.
