OATS Technical Specifications

The OATS Reporting Technical Specifications document covers the requirements and procedures for clock synchronization; system access requirements for supplying OATS files to FINRA; order reporting scenarios that describe, from a business perspective, responsibilities for reporting to OATS; details regarding the required layout of OATS files; procedures for providing corrections to OATS data and for receiving feedback from FINRA; and the procedures for registration, self-administration, and testing and certification. It also contains a data dictionary that describes all of the data elements in OATS files; a list of report formats, including field names, data types, and lists of permissible values; examples of order reports; and a glossary.
