New OTC Transparency Data Download and API Guidelines (Effective November 5, 2018)

As part of a technology modernization initiative, 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. Details are provided in the Website User Guide.

FINRA will support a new Application Program Interface (API) to enable access to the OTC Transparency Data effective November 5, 2018. Details are provided in the Data File Download API documentation. The existing methods of API access will no longer work effective November 5, 2018.
