On every change
A new transaction or a new price triggers the recalculation. It updates the affected states, up to yesterday.
Principle 3 · Daily states
Every day pre-calculated.
For every position in every consolidation Core keeps one state per day, since inception. Whoever wants an analysis reads those states instead of rebuilding them from years of transactions. That is why Core is fast.

What a state holds
A target state
A state belongs to exactly one consolidation, one position and one day. It records what was true that evening.
Consolidation · position · date
- Quantity
- units or nominal after all of the day’s bookings
- Price
- in the consolidation currency
- Accrued interest
- accrued up to that day
- Cost value
- in position and in consolidation currency
- Flows
- the day’s capital flows, the basis of every return
When it is calculated
When something changes, not when someone asks
With a fallback
Core also checks regularly whether every consolidation is current, and catches up on anything left behind.
The same as recalculating
Pre-calculating and recalculating are one mechanism. So there is no state that came about differently from the others.
What that makes fast
Ten years of return reads ten years of states
Returns, figures and reports are calculated on request from the states and flows, not from the transactions. The heavy work, following every booking since inception, has already been done.
Measured ourselves2.56 milliondaily states across eleven years and 22 consolidations, fully rebooked and revalued in just over 8 minutesMeasured on 30.09.2026 with generated sample data: “rebook and revalue all”, one worker on 4 vCPUs, PostgreSQL 16, about 5,000 states per second. Not a benchmark on production hardware.
