Data health
A coverage matrix per source, zone and product: what landed, what is late, what an upstream never served in the first place. Freshness is a fact on the page, not an assumption.
European power — EU + UK bidding zones
Surveillance for the power markets you actually trade
TradingSurv collects day-ahead, intraday-auction and continuous data from the official European sources, archives every raw payload for replay, and re-clears each delivery hour against a reconstructed merit order — so an odd price has an explanation before anyone has to ask for one.
Free to evaluate. No card until you add a paid plan.

Capabilities
Six views on the same delivery day
Each one answers a different question about the same hour, off the same normalized store.
Market snapshot
One zone, one delivery day: prices, spreads against neighbouring zones with a coupling percentage, generation mix, residual load and forecast-vs-outturn bias — read from the source APIs at request time, not from yesterday's crawl.
Price comparison
Any markets and products overlaid on one chart — day-ahead, IDA1–3, continuous and cash-out — with the volume behind each line and the source that answered for it.
Auction surveillance
Every delivery hour re-cleared against a merit order reconstructed from published fundamentals, with walk-forward calibration and counterfactual simulation behind each screen.
Bid curves
Aggregated supply and demand curves per cluster and auction, captured daily while the exchange still serves them and replayed from the raw archive afterwards.
Org-scoped workspace
Watchlists, alert rules and billing are isolated per organisation by row-level security. Market data stays shared reference data everyone reads.
How it works
From published data to an explained hour
Every number on screen traces back to a raw payload we still hold.
Collect
Scheduled workers fetch each source on its own cadence, keeping a high-water-mark cursor per stream so a re-run never duplicates a row.
Archive & normalize
The raw payload is written to object storage before anything parses it — the audit substrate a replay or a dispute needs — then normalized into plain time-series facts.
Surveil
The console reads the normalized store, tops it up with live API calls where the day is still moving, and reconstructs the merit order behind each cleared hour.
Data sources
Official feeds, named on every panel
When a feed is rate-limited or down, the panel says so and degrades — the page does not quietly show stale numbers.
