The data is public. Assembling it is the job.
A different publisher per zone, in a different format, on a different clock. One alert about one period means visiting most of them and reconciling it by hand.
Your surveillance system flags it. TradingSurv explains it.
Market context for energy trading surveillance analysts: start from the alert your platform raised and establish whether the market explains it, across 38 European bidding zones instead of 24 operators’ websites.
We do not replace your surveillance system
Your platform decides what to flag. TradingSurv sits downstream of it and answers what comes next: whether the market explains it.

The alert fires
Scila, Nasdaq SMARTS, b-next, Trapets or Eventus flags an order or a trade. Nothing about that changes.

You open that delivery period
One bidding zone, one delivery day, at the resolution the market settles on: 15, 30 or 60 minutes.

The evidence travels with it
Every figure names its publisher and publication time, and the link reopens the screen you saw.
Prices, generation against forecast, load, outages, cross-border flows, imbalance and the auction book, for 38 European bidding zones, as the operators and exchanges published them. Feed by feed on data sources, zone by zone on coverage.
An alert is a question about one delivery period
Answering it means knowing what cleared, what was generating, what crossed the borders and what the order book held. All of it is published. None of it is in one place.
Half of the evidence expires.
The aggregated bid curves behind an auction are served for the current delivery day and the next, and nothing older (measured 2026-08-13). We capture them daily, so the book is still there when the alert arrives.
A workbook is not an audit trail.
A spreadsheet assembled by hand cannot be re-run or shared as it was seen. Here the URL is the state, and every figure traces back to the raw payload it was parsed from.
The screen narrows the period. You still decide.
Every finding is an indicator for human review with its model error reported next to it, never a determination that abuse occurred.
How each screen answers its part, screen by screen, is in the learning section. What a finding may and may not claim is on surveillance.
Start with the alert on your desk
Create an account. Once an admin reviews it the console opens on the current delivery day. It is free, and there is no card.
