Intrinio Websockets API

The Intrinio Real-Time Feeds uses the WebSockets protocol to push stock price quotes to clients in real time. The Intrinio Websockets API will send you the last recorded IEX bid/ask/last quotes, even during off-hours. So you will notice that the first quote update will come through immediately upon connection, and it will have an older timestamp. All quotes afterwards are live updates. Intrinio is a financial data marketplace that is restriction-free with self-sign up, and chat support.
