THE RELIEF
Gamma, delta, vanna and charm exposure across every strike and listed expiration, drawn as one landscape and refreshed every 1–2 minutes.
THE CATEGORY
A map of the forces under price.
With the legend attached.
Gamma exposure maps have been around for years. Orogex was built on one premise: the map should come with its legend: published definitions, plain-language explanations, and named sources.
PUBLISHED DEFINITIONS
The call wall, put wall, Gamma Flip Level and regime on the map each come from a formula published on the Methodology page, so you can check a level by hand.
CITED, NOT ASSERTED
Concept articles name the research behind their claims, with a clear label where a source is a working paper or comes from an exchange. Worked examples show their inputs so you can redo the math.
TWO ALTITUDES
The same screen serves both readers: the dense strike-by-strike map for the expert, and a plain-language note on any level for someone still learning.
WHAT OROGEX RENDERS
Not a feed.A survey.
Orogex estimates dealer positioning across every strike and expiration from open interest and a stated sign convention, then reads it as one picture. The map is dense underneath and calm where you make the decision.
THE REGIME
Each expiration is labeled positive, negative or transition gamma at today's price, with its distance from the Gamma Flip Level.
STATED ASSUMPTIONS
Every exposure number rests on a stated dealer sign convention and published formulas. The Methodology page says what is measured, what is assumed, and what is an estimate.
DRAWN BOUNDARIES
- Not a broker. Orogex never routes real orders or touches your brokerage account.
- Not a signal service. No trade-of-the-day picks. The map shows conditions; the decision stays yours.
- Not a social feed. No chat rooms, no leaderboards, no influencers.
- Not a black box. The map's levels, units and sign convention are published.
- Not a course upsell. The field guide and concept library are free, for everyone.
UNDER THE HOOD
Official inputs.One source of truth.
Positioning starts from the daily open-interest count, with implied volatility and Greeks from our market-data provider.
The exposure grid on a screen is built from a single snapshot of the options chain, so its strikes and expirations describe the same moment.
Exposure is computed once when the chain arrives and every view reads the same stored values, so views built from the same snapshot agree.
