Hands-on reconstructions of the trade lifecycle — where a record comes from, what it captures, and how an analyst reads it. Synthetic throughout; not a monitoring tool.
These pieces take the order–trade–fulfillment lifecycle apart and let you work through it yourself. Some are guided walkthroughs; some are open reconstructions where you play the analyst. Each one runs on invented data generated in your browser, and none of them reads a live market or reports on real activity. Start with the reporting lifecycle, then step into the reconstruction bench, or read the manipulation simulations one pattern at a time.
A synthetic teaching lab, not a product. Download a session of invented client data, run it through reporting and a transparent surveillance pass, decide what to escalate, then see what was really in the data — what the rules caught, and what they missed.
The bench inverted. The alerts are already raised — you inherit a queue, work out why each one flagged, decide what is real and what is a false positive, and file the right report. Includes the transaction-reporting desk and a ground-truth reveal.
Both benches are teaching instruments built entirely on invented data. They demonstrate the reasoning of surveillance, not a monitoring system, and they file nothing about anyone real. The detection rules are deliberately simple and fully visible, so you can see exactly why each pattern is flagged.
A simulation covering all seven patterns, behavior-based and information-based. For each pattern it shows a clean market and a manipulated one side by side, and states the signal an analyst checks. Start here.
A simulation of ten stocks trading over the same session. Three are modeled on real enforcement cases and seven are made up. Some show a manipulation pattern and some do not, so the reader has to tell which stocks to flag and which to leave alone.
A simulation of spoofing and layering, shown one order at a time. A large order creates false depth on one side of the order book, then cancels before it can trade. The two techniques are shown side by side.
A simulation of wash trading, shown trade by trade. Two linked accounts trade with each other to raise the volume while the price barely moves. The volume pattern points to the problem; account records are what confirm it.
A simulation of momentum ignition, shown trade by trade. One account places a burst of aggressive trades to draw other traders in, then the price falls back once that account stops. The reversal follows the account's exit.
A simulation of marking the close, shown across two sessions. Heavy trading in the last minutes pushes the closing price up. The next session opens lower and gives the move back, which shows the close was pushed rather than repriced. It cannot be confirmed until the next session.
The three information-based patterns, insider dealing, pump-and-dump, and false or misleading disclosure, appear in the walkthrough above rather than as separate pages. Their evidence sits in timing, disclosure, and account records, not in the shape of the order book, so a standalone page would not reflect how they are actually found.
