About dxFeed

dxFeed is a subsidiary of Devexperts, with the primary focus of delivering financial markets information and services to buy-side and sell-side institutions of the global financial industry, specifically to traders, data analysts, quants and portfolio managers.

Since its inception, dxFeed has built one of the most comprehensive ticker plants in the world, in addition to offering the broadest range of data services currently available by a single company in its space.

Financial data is delivered from a variety of exchanges in North America, Europe and around the world.

API Structure and Data Specification

All events that occur on exchanges (placed and canceled orders, trades, and so on) are received by dxFeed in individual formats and in accordance with the protocols of each exchange. Hereupon dxFeed normalizes all the data into its own records with a predefined set of fields — dxFeed internal QD-model (Quote Distribution).

Here's an example response object for both a Quote and a Trade.
