Derivatives 3
Option Greeks ManifoldA long call's P&L as a 3D surface over spot price and time to expiry. Orbit it, and reshape it by any Greek.
Realized Volatility ConeA 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.
Variance-Risk-Premium StripImplied 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.
Market structure 6
Market APEX BoardA 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 CrowdOpen-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 BoardA 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.
Market ConstellationEvery 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 MonitorPer-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.
Breadth and Dispersion BoardA 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 is marked, not hidden.
Macro 2
Yield Curve DynamicsA 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.
Macro Phase PortraitInflation, 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.
