Surge detection
The moment it starts.
Surge watches the session for clusters of large, aggressive orders landing on one name in a short window, and draws the spike where it began — with price on the same axis for context.
Platform capability — in verification
This capability is active in the authenticated platform. Delayed-tier entitlement boundaries, claims evidence, and runtime telemetry are currently undergoing verification against FEATURE-REGISTRY.md. This specification page remains unindexed (noindex, follow).
The surface
What you're looking at.
Bursts, not trickles
Cumulative call and put premium are drawn together, so a sudden step in one line stands out from steady background flow.
Timing on the axis
Each surge sits at its session timestamp, so you can see what else was happening around it — including price.
Straight to the prints
A surge is an aggregate of recorded trades. Drop into Live Flow to see the individual prints inside the window.
Discipline
How to read it step by step.
Watch the slope
Steady flow draws a smooth curve. A surge is a visible kink — premium arriving faster than the session's baseline.
Compare call against put
The same burst reads differently if the other side is bursting too. Both lines share one axis so the imbalance is visible.
Check price at the moment
Price is drawn on the same timeline. What it did around the surge is context — the conclusion stays yours.
