QuantConnect launched QuantConnect Datasets, a platform where a quant can harness a data feed with a single line of code and begin live-trading in minutes. QuantConnect gives quants access to some of the most in-demand market and alternative data sources, such as Tiingo News Feeds, Quiver Quantitative’s WallStreetBets Discussion Data, Benzinga, RegAlytics, Brain, and many others. The ultimate goal for the platform is to bring together thousands of data providers and quants.
