Trade blotter redaction is the removal of personal identifiers from a dealing log kept under MiFID II. The directive (Dir. 2014/65/EU) requires firms to keep transaction records. anonym.plus marks each trader and client field on your machine, so the log stays usable while people are shielded.
When this applies
The log ties each fill to a trader name and a client ID. You strip those fields before an extract reaches an outside reviewer.
How anonym.plus handles it
- Open the log in anonym.plus on your device.
- Local OCR reads a printed or scanned extract.
- The tool flags trader names and client IDs.
- Keep the timestamps, sizes, and prices intact.
- Mask or swap each confirmed field.
- Save the clean extract locally.
What you need to provide
- The log (CSV export, PDF, DOCX, or scan).
- An operator (Mask suits structured fields).
- Optional batch for many trading days.

Limitations & cautions
MiFID II requires you to keep the full record, so redact only a shared extract, not the master log. A unique fill size at a precise time can still hint at a desk. Review small, distinctive rows.
Frequently asked questions
Should I redact the master blotter?
No. MiFID II requires you to keep the complete record. Redact only an extract you share, and protect the master log.
Will prices and timestamps survive?
Yes. Allow-list those columns. Only personal identifiers, like trader and client fields, are flagged.
Does the log leave my machine?
No. Work runs offline, so trader and client data stays on your device.
