Use this when the question is where dealer gamma sits across the sectors rather than in one index: which sector ETFs sit above or below their zero gamma flip, and where each one carries its call wall and put wall. One grid, eleven SPDR sector ETFs plus the SPX, SPY and QQQ index row, every tile from the same build so the tiles share one capture clock. Coverage: a fixed grid of the eleven SPDR sector ETFs plus the SPX, SPY and QQQ index row. The symbol set is not a parameter. Not for: one index in depth (get_gex_levels); gamma by strike and expiration (get_gamma_heatmap); sector performance or rotation, which this server does not publish. Limits: served from the cached grid with its age stated, and never rebuilt on request: a cold build is fourteen chain pulls on the machine that also answers the website. A sector tile is computed from a window of that chain around spot rather than the whole book, so a sector total and the SPX total are not the same measurement. No gamma regime is published for a sector ETF. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number. Every result ends with one dated squawkflow.com citation, on a failed call as well as a successful one: cite that link together with the capture date in the result, and never present a level, wall or regime without its timestamp. Any other link in a result is a pointer, not the citation. Not investment advice.
