Important Update: Alpaca Launches Market Data API 2.0


Data is one of the most important components of algorithmic trading and is the backbone for generating signals. Here at Alpaca, we continue to improve our product offerings as well as your Alpaca experience and hence we are excited to announce our Alpaca Data API version 2!

The API v2.0 will consist of real time and historical price data and will evolve with more upgrades with time. Starting from the 27th February 2021, the Alpaca Data API v2.0 will replace the existing data feed that has been offered to live accounts. Furthermore, this switch means that all services through Alpaca will soon be discontinued.
