What is Expo?

Expo is the dealer-positioning map. Pick a ticker, a Greek (gamma, delta, charm, or vanna), and a set of expirations, and it renders where dealers are forced to hedge: the gamma flip, the call and put walls, and the whole exposure structure, four different ways from the same data.

The levels are computed once and drawn identically in every view, so the stat strip, the chart lines, and the table always agree. It answers the questions traders prepare with. Which strikes will dealers defend? Where does price tend to pin? Which zones suppress or amplify volatility?
