OATS Reportable Security Daily List

The OATS Reportable Security Daily List is a list of all NMS stocks and OATS reportable OTC equity securities representing the current trading day. FINRA publishes two files each day, one representing the list of reportable securities as of the start of the trading day (SOD) and a second file representing the list of reportable securities at the end of the trading day (EOD). The SOD OATS Reportable Security Daily List is published daily by 6:30 a.m.EST and the EOD OATS Reportable Security Daily List is published by 6:30 p.m.EST. The EOD file contains any securities added during the trading day. Securities deleted during the trading day are not included in the EOD file. To ensure all securities reportable during any given trading day are identified for reporting, firms are encouraged to use both the SOD and EOD files.
