Dealer flow: forced-vs-voluntary attribution
Regime: multi-factor stability metrics
Vol surface: dynamics, curvature, asymmetry
Microstructure: tick-precision flow primitives
Cross-asset coverage with named methodology choices: dealer-hedging tape, physics-based regime transitions, per-venue order flow, charm-flow 0DTE.
Atlas Factor Library
Cross-asset, tick-cadence. Built around the questions most teams stop at: who is forced and who is voluntary, when a regime is becoming unstable, what an alpha looks like before it shows in price. Not a list of features. A body of research.
