Every Strike. Every Greek.
Full-chain gamma, delta, charm, and vanna, mapped strike by strike from 0DTE to LEAPS. See exactly where dealers are forced to hedge.
The hidden side of every move.
Dealer hedging, mapped in time
The Field maps forced dealer hedging across price and time, so you watch the book resolve from a broad morning surface into the handful of strikes that actually matter into the close.
It is a Black-Scholes surface, not a coloured strike table. Every contract's influence narrows as expiry nears, which is why the walls separate into distinct peaks exactly at the hour the pin decision lands.
Strike by strike, expiry by expiry
The Table ranks every strike with its call and put side broken out. The Matrix turns the same book sideways, so you see which walls survive past today and which vanish at the closing bell.
Four Greeks, not just gamma
Gamma, delta, charm and vanna on the same surface, each with its own levels and colours, because the structure driving the last hour is rarely the one that opened the day.
Three views of the same book
Field, Table and Matrix all read one set of levels, computed once. Map the hedging over price and time, rank it by strike or spread it across expirations, and the numbers never disagree.
Gamma flip, frozen at the open
Most flip levels chase live price, which makes them impossible to trade against. Ours is swept across sixty one price levels and held to the morning book, so above it you fade and below it you follow.
Four panes, four symbols at once
Split the workspace across fourteen layouts and give every pane its own ticker, Greek, expiration and levels. SPX Field beside SPY Table beside QQQ Matrix, then snapshot the whole grid.

The bar above sets what you see. The rail beside keeps your symbols, alerts, and flow one click away.
The top bar is built for Expo. Switch ticker, swap between Field, Table, and Matrix, change the Greek, and filter to any expiration without leaving the screen. Down the right rail sit your Watchlist, your Alerts, and a full Ticker Details dashboard, each one tracking whatever symbol you have active.
