How it actually works
- 01
Dealers take the other side
Someone sells a call, a market maker buys it. Their book ends up long or short gamma against the customer, and they do not want the directional risk that comes with it.
- 02
Long gamma damps the move
When dealers are net long gamma they hedge against the move — selling into strength, buying weakness. Their hedging works as a brake, and realised volatility compresses.
- 03
Short gamma amplifies it
Net short, the hedge flips direction: they buy strength and sell weakness. Now the hedging pushes the same way the market is already going, and moves extend rather than fade.
- 04
The flip point is the boundary
The spot level where net gamma crosses zero separates the two regimes. Above it and below it the same news produces a different day.
GEX is a model, not a measurement. It stands or falls on the assumption about who sits on which side of each contract. We show you the computation — per strike, with the call and put split — so you can judge for yourself where it holds and where it does not.

The levels page
Walls, flip and regime rendered on a live chart, for the symbols most people watch. It is a picture, and a picture is enough if you are trading it by hand.

The same numbers as JSON
Per-strike exposure, the call/put split, DEX, vanna and charm, on your existing API key. It is an input, and an input is what you need if something else is deciding.

What this is not
- Not a signal. A wall is a level where hedging concentrates, not an instruction to trade it.
- Not a measurement. Dealer positioning is inferred, not reported. We publish the assumption instead of hiding it.
- Not directional on its own. Our own 31-day study found no level that beat its mirror placebo — walls held 87.6% of the time against 90.7% for random levels. What did reproduce cleanly is the regime: negative gamma runs about 40% more volatile. Use it for sizing, not for targets.
- Not a replacement for the option data underneath. If you want to compute your own exposure, buy the chains instead.
- Not a professional licence. Trading your own account is non-professional use; if a firm pays you to look at this, or your users see it, the exchange treats that differently — the arithmetic is public.

Gap history is public →Where these numbers come from
| Figure | Source | Checked |
|---|---|---|
| Levels are non-naive | Each strike is evaluated with its own Black-Scholes greek AT that strike — the hedging force if price traded there — not with today's spot-decayed greek | 2026-08-03 |
| Computed from our own chains | Live option chains off our own feed (QQQ for NQ, SPY for ES, ETF proxies for GC/SI/CL), strikes mapped onto the future via the live ratio | 2026-08-03 |
| Negative gamma reproduces ~40% more realised vol | Our own 31-day intraday study on wandering levels. The same study killed the directional claim — see the note below. | 2026-07 |

The third row is the uncomfortable one and it stays on the page. We tested our own product's most marketable claim and it did not survive; the regime claim did. Both are here.
