QuantConnect is an open-source algorithmic trading platform that provides its community of over 90,000 quants with access to financial data, cloud computing, and a coding environment where they can design algorithms. Users develop trading strategies in Python and C#, backtest them, and then deploy them into their brokerage trading accounts! We are a truly global company with users from all over the world who have created more than 1M algorithms and live traded more than $1B in notional volume. In early 2018 we launched Alpha Streams. It is a revolutionary approach to alpha search, allowing proprietary trading funds to search and license alpha via API. This gives our community the opportunity to license their algorithmic strategies to quantitative trading firms, earning income, and helping funds find great trading signals.
