Trade surveillance for FINRA broker-dealers

Yesterday's trading, reviewed before the open.

TradeMonitor collects your firm's order and execution files every morning, runs the surveillance checks your written procedures call for, and puts every exception in front of a named reviewer with a due date. Daily, monthly and quarterly reports are saved unchanged, ready for an examiner.

What it does

One unattended run every weekday morning

No software to install and no live feed to watch. When your reviewer signs in, the day's work is already waiting.

6–7 a.m. ET

Collects the files

Pulls the previous day's orders and executions from your REDI file server. Other files can be uploaded by hand.

Kept as received

Keeps the original

Each file gets a digital fingerprint when it arrives, so you can show it was never changed.

Every order

Runs the checks

Orders are rebuilt with every change and fill, matched to market volume, and tested against your firm's limits.

Before the open

Queues the exceptions

Each one goes to a named reviewer with a due date. A missing file sends an email, never a silent gap.

Evidence of review

Reviewed, signed off and in your inbox. Every day.

When FINRA asks how your firm supervises its trading, the answer is already in your email. Once the day's alerts are resolved, TradeMonitor sends the Daily Exception Report on its own, with every alert, the reviewer, the decision and the reason.

  • Sent automatically, every trading dayNo one has to remember to run it. The report goes out once the day's reviews are done, at the time your firm picks.
  • Proof of who reviewed what, and whenEach alert shows the reviewer's name, the decision and the written reason, dated and locked.
  • The right people get itYour CCO, supervising principals and, if you like, your outside auditor. People who leave the firm stop getting it automatically.
  • A copy is always keptEvery PDF sent is saved unchanged with its digital fingerprint, so you can show exactly what went out and when.
