Technical Notice

Reminder - TLS Upgrade and ORF Next Day Dividend

March 1, 2018

Effective Monday, March 12, 2018, the FINRA TRACE, ADF and ORF Web API reference data downloads will no longer be accessible using the Transport Layer Security (TLS) 1.0 protocol. FINRA will disable TLS 1.0, and firms using that protocol will not be able to establish connectivity to FINRA’s secure web servers to download the files. To gain access to the FINRA API reference data downloads, firms must migrate to TLS versions 1.1 or 1.2 by March 12, 2018.

The protocols and cipher suites listed below will be the only supported ciphers and protocols by the API reference data downloads and the FINRA TRAQS website.

Cipher Suites

# TLS 1.2 (suites in server-preferred order)


# TLS 1.1 (suites in server-preferred order)


NOTE: TRAQS users should also ensure their browsers currently support TLS versions 1.1 or 1.2. Any TRAQS user attempting to login whose browser only supports the TLS 1.0 protocol will be denied service.

FINRA has also updated the Over the Counter (ORF) API Reference Data specification to coincide with data changes that will take effect on Monday, March 12, 2018. Beginning Monday, March 12, 2018, the Next Day Dividend File will be amended to include a Record ID.

Questions regarding this notice should be forwarded to FINRA Product Management or call (866) 899-2107.
