Vol Calendar
What this shows & how to use it
The data: Third-Friday SPX OPEX, Wednesday VIX expiries, and quarterly Quad Witching dates, plus what phase of the monthly gamma cycle you're currently in.
What it means: These are calendar-driven mechanical events. OPEX = the biggest monthly gamma reset. VIX expiry = SPX AM opening print settles VIX options → outsized 9:30 auction. Quad witch = OPEX + futures + single-stock derivatives all expire together.
How it's used: Regime color tells you whether your standard playbook applies (green), whether you're in a pin/charm-heavy window (yellow), or whether there's a hedge-unwind risk day ahead (red).
ES incorporation: Mon-Wed of OPEX week → default to fade-into-walls. Thu-Fri → charm drift, respect Absolute Gamma Strike as magnet. Post-OPEX Monday → RESET everything, higher trend-day probability. VIX expiry Wed AM → wait until 9:45 to re-read GEX after settlement flow clears.
Implied Correlation
What this shows & how to use it
The data: Cboe's implied correlation indices (COR1M, COR3M) — the market's expected average correlation between the top 50 SPX components, derived from the gap between index IV and single-stock IV.
What it means: Low (<20) = names moving independently, rotational tape, index vol suppressed. Rising toward 40+ = market is pricing that everything will move together on the next shock. High correlation = macro-shock regime where GEX walls fail.
How it's used: This is the leading indicator that your gamma playbook is about to stop working. Watch the divergence flag — when SPX makes highs but COR1M is also climbing, a correlated selloff is being priced in beneath the surface.
ES incorporation: If COR1M is in the low regime, trust GEX pins on ES and fade wall tests. If elevated + rising, reduce mean-reversion size and respect breakouts. If high + rising with SPX up = the biggest warning signal on this deck — flip to trend / short-vol-collapse playbook.
Advanced Gamma Levels
What this shows & how to use it
The data: Absolute Gamma Strike (single strike with the largest |GEX|), gamma density around it, zero-gamma flip level, and distance from spot in both SPX points and ES points.
What it means: This is the field shape layer that complements your existing walls panel. The Absolute Gamma Strike is the strongest pin candidate. Density tells you whether the pin is tight (clustered OI) or diffuse (spread-out OI = mushy level). Zero-gamma line separates suppression (above) from amplification (below).
How it's used: Distance-from-flip tells you how deep in the current regime you are. Density tells you how sharply price will react at the pin. This is the "how much respect does this level deserve" layer.
ES incorporation: Convert the SPX Absolute Gamma Strike distance to ES points to set your magnet target. If density is "Dense — tight pin", trust fades into it. If "Diffuse — mushy", expect slippage through the level. Cross-check against your existing ES/NQ Command Deck walls before entering.
Charm & Vanna Drift
What this shows & how to use it
The data: Estimated dealer hedging drift over the next 60 minutes driven by charm (delta decay from time passing) and vanna (delta change from IV moving). Expressed in ES points bias.
What it means: Options age. As time passes, OTM options' deltas drift toward zero — dealers who hedged yesterday must adjust today even if nothing else changes. That's charm. Similarly, when VIX drops, dealer short-put deltas shrink and they buy stock — that's vanna. Both flows are mechanical and directional.
How it's used: Think of this as the tape's tailwind or headwind when no news is active. Strongest in the last 90 min of RTH and first 30 after the open. If the tape is fighting the drift, something real is happening — that's a signal to size up or step aside.
ES incorporation: On quiet days, this is your intraday direction-of-least-resistance. On Thu-Fri OPEX, charm accelerates and often pins ES to the Absolute Gamma Strike. Vanna kicks in when VIX is bleeding lower — that's usually a green-tape confirmation even without a catalyst.
OPEX Effect
What this shows & how to use it
The data: Where you are in the monthly gamma cycle — OPEX Mon-Wed, OPEX Thu-Fri, post-OPEX reset Monday, quad-witch cycle, or mid-cycle normal.
What it means: Each phase has a distinct expected market behavior. OPEX week has the tightest ranges of the month because positive gamma is at its peak. Post-OPEX Monday is the biggest regime shift day of every month — old OI disappears, walls re-form.
How it's used: The phase determines your default playbook before you look at anything else. It answers "should I be fading or breaking out today?" purely from the calendar.
ES incorporation: Mon-Wed OPEX = mean-revert. Thu-Fri OPEX = pin + charm drift, small size. Post-OPEX Mon = re-pull walls, expect trend day. Quad-witch Mon = biggest post-reset move of the quarter. Set your daily bias with this first, then confirm with GEX and Charm.
