Why do I need to archive my data?
All FINRA registered investment advisors are required to keep books and records of any communication to clients and any advertising they do in the course of the work in their firm.
This data must be archived in an uneditable format — that means keeping emails in your inbox for a regulator to look at later doesn't cut it.
SEC Rules 204(2) and SEC Rule 17a-4 explain in further detail the books and records requirements for you as an IAR.
