GammaDesk is a focused analysis cockpit for short-dated options across 30 symbols - index products, ETFs and single stocks. It computes dealer gamma exposure (GEX) from the live options chain and turns it into the levels that matter intraday. COVERAGE Indices and ETFs: SPX, NDX, SPY, QQQ, DIA, VOO Mega caps: AAPL, MSFT, NVDA, GOOGL, AMZN, META, TSLA Single names: ADBE, AMD, APP, ARM, AVGO, COIN, CRWD, CRWV, FSLR, INTC, LLY, MRVL, MSTR, MU, NBIS, NOW, QCOM The nearest live expiry is picked automatically for every symbol, so there is nothing to configure. The GEX profile rescales to each symbol's own strike grid, which means a $40 stock and a 6,000-point index are both read at a sensible resolution. WHAT YOU GET - Live GEX profile by strike, with the zero-gamma flip and the dealer positioning regime - Call wall and put wall levels, plus the ATM expected-move range - A deterministic directional bias built from four transparent signals, not a black box - A plain-language forecast of the likely range, with a Pro mode that switches to technical terms - A live intraday price target drawn from today's volume-weighted gamma - Session guardrails: no-entry cutoff, 0DTE close warning, economic-event blackouts, and a gamma regime-change alert BUILT FOR CLARITY GammaDesk does not place trades and never tracks profit or loss. Every signal is derived from market data, the clock, and the calendar. All market-hours logic is pinned to US Eastern time. IMPORTANT GammaDesk is a personal analysis tool. Market data may be delayed or estimated and may be inaccurate or unavailable. Dealer positioning values are model estimates, not measurements. This is not investment advice.
