Daily net dealer gamma (summed across all strikes and expirations).
• Positive = volatility suppression → favors mean-reverting regimes
• Negative = volatility amplification → favors trending/breakout regimes
Days when net gamma crosses zero ("gamma flips") have historically marked elevated volatility periods.
• Today (Live) switches to spot GEX sampled through the session — net dealer gamma minute by minute.
Net dealer gamma by strike (today's snapshot).
• Large positive bars (call walls) act as price magnets and resistance.
• Large negative bars (put walls) act as support.
• Today Only (0DTE) isolates the walls in contracts expiring today — the levels that matter for same-day options.
• Live switches from the overnight open-interest snapshot to spot GEX, which updates through the session.
Gamma exposure broken down by option expiration date.
Gamma exposure values are end-of-day estimates based on settled open-interest data and the standard dealer-positioning assumption (customers buy puts and sell calls, dealers take the other side). Live views use spot GEX, which re-estimates the same exposure through the session as price and volume change. Real dealer positioning can differ from the assumption when large institutional hedges flow in the opposite direction. Treat as one signal among many, not a deterministic price target.
