The daily warm is the once-a-day sweep that asks the compute engine to recompute every strategy in your live book, so those results are already finished by the time you open them. It exists because results are tied to the market data behind them: when the daily data refresh advances, yesterday's results are no longer current and something has to recompute them before anyone looks. The warm is that something, and it is why a strategy you follow Live usually shows finished numbers rather than a progress bar.
Also seen as: pre-warm, warm-up
When does the daily warm run?
On your first visit of the day, not overnight. Opening Fincanva while signed in triggers one warm of your live book, and it runs once a day — so revisiting later in the day costs nothing and starts nothing. The sweep covers every runnable strategy in your live book: strategies whose results are already current are left alone, only the ones the data refresh made stale are recomputed, and any Live strategy parked awaiting a manual run is skipped entirely. That last one is deliberate — a strategy you edited and did not re-run is waiting for you to run it, and the warm never recomputes an edited strategy on your behalf. Public strategies are not part of it: they are kept warm by a separate server-side sweep of Fincanva's own, which is why a public strategy you have never touched can also open with finished results.
Which strategies are warmed?
Your daily warm covers the strategies you have marked Live — the ones that make up your live book — minus any of them parked awaiting a manual run. A strategy you have merely backtested and saved is not part of the sweep: it computes when you run it, and it goes out of date after a data refresh until you re-run it. Marking a strategy Live is therefore what enrols it in the daily warm; choosing "Stop following" takes it back out.
Defaults in Fincanva
- The warm runs once a day, on your first visit of that day.
- It does not block anything: the app renders while the warm proceeds in the background, and a warm that cannot complete leaves your last-known statuses untouched.
- It never places an order or changes a strategy — following a strategy Live is paper monitoring only (see portfolio).
- Warming a strategy whose results are already current changes nothing about it.
- Because identical setups reuse one result (see shared compute), a strategy you follow may already be current before your own warm reaches it.
Worked example
You follow six strategies Live. Overnight, new market data lands and the data frontier advances by one trading day, which makes yesterday's six results stale. At 8:05 you open Fincanva: the daily warm fires once and recomputes the ones that need it. By the time you reach the Portfolios page the fastest are already Up to date and the rest show Running with a progress percentage. You come back at 14:00 — today's warm has already run, so nothing starts again, and the results you see are the same ones computed this morning, now with one more day of history than yesterday.
Fincanva provides no financial advice. Backtests show what would have happened — not what will.
