    Why it is in this group

    • The name "get_gamma_levels" says "get": a word for reading.
    Description, as the server wrote it
    Modeled options dealer-positioning levels for one underlying: gamma flip, call wall, put wall, max pain, same-day pin strike, and net dealer gamma at spot (whose sign is the regime). Use for "where is the gamma flip", "where are the walls", "is SPX in positive gamma". FREE DELAYED DATA - at least 15 minutes behind live, and the response states its own age; quote that age and never call these levels live. Not a price feed, not a forecast, and not a trade recommendation: it describes dealer positioning and says nothing on its own about direction. A null level means the modeled book does not support that level right now - report it as unavailable, never as zero.

    Why it is in this group

    • The name "get_market_gamma_overview" says "get": a word for reading.
    Description, as the server wrote it
    One-line dealer-positioning summary for all six covered underlyings (SPX, SPY, QQQ, NDX, ES, NQ) in a single call: spot, modeled regime and gamma flip for each. Use for broad openers like "what does dealer positioning look like today" or "which indices are in negative gamma", instead of calling get_gamma_levels six times. Same free 15-minute-delayed data and the same caveats. When the question is about one symbol, call get_gamma_levels instead - this tool omits the walls, max pain and pin strike.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
