Tick Size Pilot Security Master File Downloads

FINRA encountered an issue with the Tick Size Pilot Security Master File ( this morning, which caused some users to download the file for February 28 rather than the file for March 1, when accessing the Master file this morning. This issue has now been resolved. It did not impact the Tick Size Pilot Changes file, and the only difference between the Security File for February 28 and the Security File for March 1 was the removal of one symbol, LIOX, from the master effective today.
