Large Options Positions Reporting

The OCC has developed and is currently hosting the Large Option Position Reporting (LOPR) system. This system allows firms to submit their LOPR files to OCC to maintain compliance with FINRA Rule 2360(b)(5) and the exchanges' rules.

Inbound LOPR and In Concert group submissions are received and processed by OCC to maintain a LOPR database. The OCC sends outbound rejected In Concert data, rejected LOPR submissions and backdated LOPR submissions to submitting firms and regulators. In addition, firms can subscribe to a nightly LOPR Snapshot file that contains all of the firm's valid LOPR records on the LOPR database. Below you will find various reference materials regarding LOPR.
