Option Greeks Manifold
A long call's P&L as a 3D surface over spot price and time to expiry. Orbit it, and reshape it by any Greek.
Drawdown Topology
A fan of Monte Carlo equity and drawdown paths. Toggle Gaussian vs fat-tailed regimes and watch the tails thicken.
Correlation Regime Dynamics
A rolling correlation matrix as a 3D field of bars. Scrub or play the calm-to-crisis shift and watch diversification collapse.
Yield Curve Dynamics
A Treasury yield curve as a 3D maturity-by-time surface. Scrub or play the shift from normal to inverted and watch the recession signal form.
Market APEX Board
A six-lens board over the public ranked universe: race the trading year, map valuation versus momentum, explore any factor pair, see what moves together, scan every factor at once, and read sector rotation.
Insiders vs. the Crowd
Open-market insider purchases (SEC Form 4) against Reddit chatter for 550+ names: quiet accumulation, consensus conviction, and all-talk corners, refreshed daily from public data.
Seismograph Board
A 2D beeswarm of every universe name's one-day move expressed in units of its own daily realized vol (z = move / vol), colored by sector and winsorized at ±4σ. A +2% day means something different for a sleepy utility than for a chip name; the board reads that dispersion at a glance.
Macro Phase Portrait
Inflation, unemployment, and the policy rate as a single glowing trajectory from 1960 to today. Scrub the decades and watch the stagflation loops, the Volcker dive, and the COVID spike.
Market Constellation
Every name on the public board becomes a star in a force-directed galaxy: sectors form the clusters, factor similarity draws the edges. Click a cluster or a single star and jump straight into that symbol's grade and its other visualizations.
Factor History Monitor
Per-factor forward-return quintile spread and rank information coefficient over time, each with an indicative bootstrap band and a printed sample count. Ships dark until 60 resolved trading days exist, because an honest monitor refuses to draw a chart the sample cannot support.
Realized Volatility Cone
A stock's realized annualized volatility across lookback horizons {10, 21, 63, 126, 252} days, drawn as percentile bands with today's term structure threaded through the historical envelope. Pick any S&P 500 name; the bands come straight from its baked realized-vol history.
Breadth and Dispersion Board
A board-level read of the whole universe: the percent of names above their 50-day average, the raw advancer and decliner counts each day, and the cross-sectional dispersion of one-month returns. Counts are raw, never indexed; the 90-day data boundary and the 50-day-proxy warmup gap are marked, not hidden.
Variance-Risk-Premium Strip
Implied 30-day SPX vol (VIXCLS) against the SUBSEQUENT 21-day realized SPX vol since 1990, with the premium shaded as the gap: green where implied over-prices the calm that follows, red where the 2008/2020-class crises drive realized above implied. Realized is subsequent, not concurrent, so the premium is a real forward comparison.
Sectors
Every sector on the public board, ranked, with links into the visualizations.
