Flow momentum — the 1st derivative (rate of change) of the options-flow gauges: skew, put/call ratio, delta tilt, premium flow. It catches a turn BEFORE the level looks extreme — the leading edge.
Intraday vs daily — the top chart is intraday (snapshots recorded through the session); the bottom is daily acceleration over 104 days of OPRA history (0DTE gamma concentration, charm term steepness, total GEX), shown as a z-score vs each gauge's own norm.
Direction — fear rising (skew/PCR up) → ↓; positioning/flow turning up (Δtilt / premium to calls) → ↑. The net is the pulse.
Accumulation — intraday momentum needs ≥2 snapshots over time; it self-records each call and a cron tops it up. Until then it reads ~flat and says so.
The call — near/mid-loaded (a turn fades by ~1w). Distinct from every level-based voter. Feeds Oracle; weight set by Phase-3 calibration.
