Every night, after open interest settles, the liquid board is run through the QL Hedging Desk engine and every underlying is placed on a map by the mechanical flow regime dealers will impose on it tomorrow: whether hedging will amplify moves or pin them, whether a vol spike forces selling, and whether the gamma flip sits close enough to invert the reflex intraday. Each regime call is recorded at sweep time and graded the next session against realized range — a forward-only track record no positioning vendor publishes.
Left of centre dealers amplify moves (short gamma), right of centre they pin them (long gamma); higher means a vol spike forces dealer selling, lower means it meets a mechanical bid. Bubble size is the stock dealers must transact per 1% move. Territories are drawn around each regime cluster; click a cluster card to focus it, a bubble to open that underlying's full desk.
A regime call is not a forecast of direction — it is a claim about range. Amplify calls expect the next session's move to exceed the underlying's own normal daily range (the trailing 20-session median); dampen calls expect less. Flip-hold asks whether the close stayed on the same side of the gamma flip. Every grade is applied the session after the call, never rewritten, never backfilled.

Choose a joint spot and vol state and see the stock dealers across the whole board must transact to get back to delta-flat. Every value is interpolated from each underlying's stored response surface — the dealer book fully repriced at that state by the engine overnight — not today's greeks multiplied by a move. Red is mechanical supply, green is mechanical demand, sized against each name's own average daily volume.
