Test Phases – Reg T, SEA Rule 15c3-3 and FINRA Rule 4230(b): Customer Test Environment (CTE)


To assist firms in preparing for the update, FINRA has created a REX CTE that firms may use to test extension of time requests using the online form or the batch process. FINRA encourages firms to begin testing as soon as possible, to ensure their readiness to file extension of time requests when the updated REX system is implemented on May 31, 2020. The testing phase is summarized below.

During the testing phase, firms must use their current FINRA Gateway user ID and password to log into the FINRA Gateway CTE. Firms that encounter technical problems, or that need to request a FINRA user ID and password, may contact the FINRA Help Desk at (800) 321-6273.

Effective May 31, 2020, firms will be required to submit only the last four digits of a customer’s Social Security or tax identification number when requesting extensions of time under Rule 4230(a). Also effective May 31, 2020, FINRA is updating certain validation identifiers and validation criteria that will affect the Reg T extension request timeframes (see Appendix A of Regulatory Notice 18-30). The testing cycle will begin on December 9, 2019. FINRA reminds firms of the following: 

  • Firms may submit extension of time requests related to Regulation T and SEA Rule 15c3-3 via both the FINRA CTE Gateway online request form and the batch process.

  • During this testing cycle, firms must submit the last four digits of a customer’s social security number or tax ID for Reg T and SEA Rule 15c3-3 extension of time requests. During this testing timeframe, the new validation identifiers and validation criterial will be in effect.

  • Batch files must use the updated schema. See section REX System Data Dictionary and Schema Documentation
  • Batch submissions should follow the below:
    • The batch submission process is outline in the Secured File Transfer Protocol (SFTP) Interface for Data Intake. FINRA is reminding firms of the new centralized, secured file transfer platform (SFTP) called fileX. Firms will need to whitelist the new FINRA fileX IPs to successfully connect with the FINRA servers and update scripts or configurations that drive the existing SFTP transfers in order to transfer files using fileX. The required actions to transfer files using fileX are outlined in the Regulatory Extension (REX) System File Transfer Service Migration to fileX notification.
    • Firms that transmit test files vis SFTP will be required to send files to their current SFTP test server into the rex/in subdirectory
    • During testing and post implementation, the batch file submission for Regulation T and SEA Rule 15c3-3 extension of time requests must be made through a file uploaded via FTP or SFTP to the subdirectory rex/in. 
    • When a firm elects to use the REX batch file format, the firm receives an enhanced XML results report via FTP or SFTP (depending on how the batch file was submitted). The results report is an XML-formatted file that contains all of the information regarding all extension of time requests the firm submitted, including extension requests submitted via the online request form. The report will be available the business day after the request(s) was submitted.
    • For testing purposes, the reports will be available the next business day after the request(s) was submitted, on the same test server in the firm’s /rex/out
    • The finalized report, which is available, as part of the batch result report and through the FINRA Gateway has changed due to limiting the extension of time submission to only the last four digits of a customer’s Social Security or Tax Identification Number. To assist firms the fields: Customer Firm CRD, Submitter Reference ID, Domestic Customer Account Number, BatchSubmitterCRD have been added to the batch finalized report.
