New OTC Equity Short Interest and OTC Threshold Data Download and API Guidelines (Effective November 5, 2018)

September 4, 2018

As part of a technology upgrade, FINRA has implemented improved interfaces to retrieve data and has established naming conventions that follow industry standards. This change will promote consistent column names, both in the file download feature and API access.

FINRA will change column names and the order in which the columns are displayed in the download files.

FINRA will support a new Application Program Interface (API) to enable access to the OTC Equity Short Interest and OTC Threshold Data effective November 5, 2018.

Details for Equity Short Interest are provided in the Equity Short Interest Data File Download API documentation.

Details for OTC Threshold are provided in the OTC Threshold Data File Download API documentation.

The existing methods of API access will no longer work effective November 5, 2018.
