Thirteen weeks of daily bars (SPX, ES, SPY tabs). Y-axis is −5% below the window min close and +5% above the window max close.
VWAP (q) — cumulative VWAP, reset each calendar quarter.
Put floor / call ceiling — outer strikes on the net-gamma curve.
JPM collar — short call, long put, short put; steps at quarter open.
Badge states
Above VWAP — latest close is above quarterly VWAP (green).
Below VWAP — latest close is below quarterly VWAP (red).

Move Envelope History · SPX

Move envelope history
Top panel: spot. Bottom panel: Pin Room Index (PRI) with 5-day smoothing — how much of the IV daily move remains after dealer walls cap upside or downside.
Reading PRI
0–30% — pinned zone; walls constrain at least one direction.
70–100% — open zone; IV budget not wall-limited on both sides.
Green/red faint lines — raw up/down room %; purple line — 5d SMA PRI.
Badge states
PINNED — recent PRI below historical mean in the pin zone.
OPEN — PRI elevated vs mean; walls not binding both sides.
NEUTRAL — mid-range vs the window mean.

Daily Move Envelope · SPX

Daily move envelope
Horizontal price ruler centered on spot. The purple band is the IV-implied ±1σ daily range (ATM IV or VIX ÷ √252). Brackets show effective upside and downside in points — capped by dealer call/put walls when walls sit inside the IV budget.
Key levels
Call / put wall — largest positive GEX strikes above/below spot.
Floor* — what-if gamma extrema floor when nearest expiry is excluded.
PRI — Pin Room Index: min(upside room, downside room) as % of IV day move.
OPEN — both sides IV-limited; full daily range available.
FLOOR* — hypothetical floor below put wall dominates downside.

Maturity Wall
@gammacharts
Maturity wall
The maturity wall shows how much corporate and government debt is coming due over the next several years, and — critically — how much of it must be refinanced at today's higher rates. As cheap pandemic-era debt matures, issuers face a fundamental choice: pay down debt or roll it at dramatically higher costs.
A large, near-term wall in a high-rate environment creates earnings headwinds and potential solvency stress for leveraged issuers. Use this chart to understand where refinancing pressure clusters and which years carry the greatest structural risk to credit markets.

Sector Rotation
@gammacharts
Sector rotation
The Relative Rotation Graph maps where each name sits in its performance cycle relative to the benchmark. The X-axis is relative strength (outperforming vs underperforming); the Y-axis is relative momentum (improving vs fading). The trail shows recent rotation path.
Names tend to move clockwise: Improving → Leading → Weakening → Lagging → back to Improving. Use it to spot early leadership (Improving) vs late-cycle peaks (Weakening).
Tabs
Benchmark Indexes — SPY, QQQ, IWM, DIA, TLT, GLD. Cross-asset leadership: large-cap vs growth vs small-cap vs Dow, plus duration and gold as risk-off anchors. Use this tab for macro regime — which beta sleeve is winning.
11 S&P Sectors — GICS sector ETFs (XLK, XLF, XLV, XLE, etc.). Classic sector rotation wheel. Use this tab for cyclical vs defensive positioning and where institutional flow is rotating within the index.
S&P Themes — Thematic sleeves: semis (SMH), credit (HYG), EM (EEM), biotech (XBI), regional banks (KRE), homebuilders (XHB), metals (XME), bitcoin (IBIT), China internet (KWEB), and DRAM. Use this tab for risk-on / risk-off themes beyond plain sector labels.
Maga Cap — Mega-cap single names (META, MSFT, GOOGL, TSLA, AMZN, NVDA, AAPL, TSM, AVGO). Tracks whether index leadership is narrowing into a handful of names or broadening out. Pair with RSP/SPY on Macro for participation context.
Quadrants
LEADING
Outperforming the index and momentum is positive. Established relative strength.
WEAKENING
Still outperforming, but momentum is fading. Often late in the relative cycle.
LAGGING
Underperforming with negative momentum. Weakest relative phase; watch for bottoming into Improving.
IMPROVING
Underperforming but momentum turning up. Often the earliest rotation entry.
