What a wall is: the strike where dealers' hedging exposure concentrates. Price approaching a large call wall tends to meet hedging flow that leans against the move; losing a put wall can accelerate one. A wall is a level that usually matters — not a promise. Our index levels are graded publicly against every session for exactly that reason.
Where this data goes: this same nightly computation feeds the Intel Clearance morning wire — filings, 13F moves, dark-pool share and these walls on the names you follow, read for you by 07:40. And inside the terminal, the index books recompute through the session as 0DTE flow rebuilds the surface.
