How fast market time runs
The pace every feed's rate is scaled by: the regime's multiplier, and the heat's share stacked on it.
Intensity λ(t) and the ticks it produced
The ticks a second every feed's law asks for now, against the ticks that came. Both are ticks a second, so they share an axis; a Hawkes feed's excitation shows as a spike in λ.

What moves the market
Six numbers for the whole installation. A change applies from now; what has passed stays as it was.
Read only. The system administrator sets these for the whole installation.
The regime
A chain that turns calm and active on its own. Its two rates say how long each spell lasts.
The heat
Every tick adds to one shared heat, which fades. It is what makes a burst in one feed lift the others.
Simulated time
How many simulated seconds one unit of market time spans. One number for the run, so every feed lives in one simulated world.
A spot feed takes a new speed at its next tick. A curve keeps the step it started with until it starts again.
The tails
How far a busy market fattens a spot price's tails, with its mean and its variance held. Zero leaves every mixture as configured.
The last hour, folded
A temporal raster: time is folded, so each column is a stretch of time and each cell a slot of it, and the colour is how many ticks arrived. A cell is a count, so the picture holds at any tick rate. A spell lasts minutes, so a busy market shows as a band of columns; the strip above them says which were active.
The last two minutes, feed by feed
The zoom: one row a feed on one time axis, with the heat and the regime above it. A row draws every tick while the ticks fit; once there are more ticks than pixels it draws each slot's count against what the feed's law asks for, so a busy row stays readable. Rows brighten together when the market turns.
Every feed's law
Read here, set on the feed. A law belongs to its feed, so each row opens that feed's Arrivals tab, the one place a law is edited; the feed takes a new law when it next starts.
| Feed | Law | Ticks an hour | Sensitivity | Branching | Decay, /τ | Stable | Last 60 s |
|---|
Each feed against its law
The ticks a feed made over the window against the count its law asks for: its rate, times its sensitivity, times the market time that passed. Pick a feed to see its gaps.
| Feed | Law | Rate × sens | Seen | Asked | Seen / asked |
|---|
Gaps against Exp(1)
Each gap rescaled by the feed's law. A feed that follows its law lies on the diagonal; a periodic feed's gaps are all one.
The loop's health
How the one scheduler that owns the market keeps up. Lateness is when a tick reached its feed less when it was due.
What the loop decided
Every tick, turn, pin, setting and change of feeds, each with its clock time and its market time. The newest first.
