The Rise of Retail Investing – And What It Means for Financial Data

Retail investors are more powerful than ever across markets. This changes the way institutional and retail investors alike use data to inform their investment strategies.

What is a stock API?

A stock API (Application Programming Interface) is a set of protocols, routines, and tools for building software applications that can access and retrieve real-time or historical stock market data from various financial data providers. Using a stock API, developers can create applications that analyze stock market trends, build trading algorithms, perform technical analysis, and provide stock market information to investors and traders in real-time.

What data does stock APIs provide?

Stock market APIs can provide real-time equity prices from bids, asks, and trades. IEX Cloud offers several stock market data bundles that cover IEX’s Nationally Regulated Stock Exchange, our real time IEX exchange quote feed, as well as 15-minute delayed quotes from all exchanges, and historical stock prices for US equities with endpoints that facilitate charting stock performance.
