GammaDesk

GammaDesk is a focused analysis cockpit for 0DTE options on SPX and SPY. It computes dealer gamma exposure (GEX) from the live options chain and turns it into the levels that matter intraday.

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.
