Notes

Baseline filters: OI ≥ 5, Notional ≥ $250K, |ln(K/S)| ≤ 0.10. 0DTE contracts use mode “Always” by default and cap IV outliers at 200%. GEX scaling toggles between per-1% (S²×0.01) and per-$1 (S×1). Spot sources stay frozen per snapshot — switch via the control without re-fetching.

How to Use This Tool

  1. (Net/Zero): Treat Net Spot GEX as the base posture (e.g., +$1.2B = dealers long gamma). Zero-Gamma marks where posture flips; below it dealer flow is typically more chasey, above it more dampening.
  2. GEX by Strike: Use the toggle to switch between Net, 0DTE, 1DTE, 2DTE, 3DTE, and OPEX strike books. The chart auto-focuses the meaningful strike range, highlights the largest positive/negative bars with labels, and overlays an orange dashed line labeled Max Pain: [strike] for the active timeframe. Read tall green bars as dealer-dampening zones and deep red bars as potential acceleration zones.
  3. Calls vs Puts by Strike: Stacked view shows who dominates each strike. A strike with huge green (calls) but tiny red (puts) tells you call writers are long gamma there and will lean against moves—helpful for spotting “walls.”
  4. GEX by Expiration: Quickly see which expiry is driving the book. If one specific monthly towers above the rest, focus on that contract when tracking dealer hedges or roll risk.
  5. Gamma Profile vs Underlying: The solid line is total gamma as spot moves; the shaded band shows how sensitive that is to vol shifts. Use it to gauge where gamma flips sign and how confident that flip is. Example: if the entire band stays below zero between 640-650, expect trend-following dealer flow through that window.
  6. Gamma Regime Map: Normalizes total gamma across price. Green means dampening/mean-reversion, red means amplification/trend. The curve fades when the vol-sensitivity range straddles zero, signaling lower conviction.
  7. Gamma Pressure Split: Directional bias by timeframe (0DTE/1DTE/Weekly/Monthly) based on gamma above vs below spot. Weekly = 2-5 trading days; Monthly = front monthly expiry. Positive values imply upward pressure, negative values imply downward pressure. Treat as conditional bias, not a prediction.
  8. Heatmaps: Side-by-side GEX and VEX grids with strikes on rows and expirations on columns. Red cells mark negative exposure clusters (acceleration zones), teal marks positive (support). The TTT logo marks the single highest and lowest cells — anchor strikes — representing the strongest dealer magnet levels across all timeframes.
  9. Weekly Lookback: Available for SPY, SPX, and QQQ. Shows the last 5 trading days of snapshots captured every 15 minutes. Top zone tracks spot price, zero-gamma level, and max strike walls with regime shading (teal = dampening, red = amplification). Middle zone shows net GEX and VEX magnitude over time. Bottom strip shows directional pressure bias (0DTE/1DTE/Weekly/Monthly) as a heatstrip. Use it to see how dealer positioning evolved through the week and identify regime shifts.
