The overnight batch handles most of the work, but markets move during the day, cash arrives, mandates change, and some decisions have to be made before the close — not after it. PRISM solves intraday drift correction and deadline-bound problems fast enough to act inside the window, with the same determinism and audit trail as the nightly run.
In plain English. Most portfolio work happens overnight, when there is time. But markets move during the day, money arrives, and instructions change — and some of those decisions can't wait until tonight to be handled. This page is about the ones that have to be answered while the market is still open, in the minutes or seconds actually available. Unfamiliar words? See the glossary.
Intraday and deadline-bound optimization is a different discipline from the overnight batch, because the constraint is no longer "finish by morning" but "finish before this specific moment, every time." Average speed is irrelevant against a hard clock; what matters is the worst case, because the one solve that runs long is the one that misses the window. A system that is dazzling on a typical instance but occasionally stalls is operationally useless here — you cannot act on an answer that arrived after the moment you needed it.
That puts a premium on two properties most optimizers treat as afterthoughts: bounded, predictable runtime, and the ability to act on a high-quality answer within a tight deadline rather than a perfect one that comes too late. The decision is not exact-versus-fast in the abstract; it is feasible-in-time versus nothing.
PRISM takes the current state and the deadline and returns an in-time, high-quality action with the same reproducible record as the nightly run.
Returns a deadline-feasible, high-quality action with bounded runtime.
Engineered to return inside the window — the worst case is bounded, not a gamble.
Keeps accounts inside their tracking-error budget as the market moves through the day.
Intraday actions carry the same deterministic, auditable trail as the overnight batch.
Set your universe and latency budget to see where a conventional solver falls behind — and the decision value PRISM protects by answering in time.
In a matched-workload pilot, set the window and the quality bar and see PRISM return in time, repeatedly — with every run reproducible.
