QuantConnect
Cloud algorithmic trading platform built on the open-source LEAN engine, with research notebooks and live deployment.
QuantConnect is a cloud-based quant research and algorithmic trading platform built around LEAN, its open-source backtesting and execution engine, supporting Python and C#. It provides hosted research notebooks, historical data across equities, forex, futures, options and crypto, cloud backtesting compute, and one-click deployment of strategies to live brokerage accounts. The free tier gives unlimited backtesting with community support and a small compute allocation; paid tiers add more compute nodes, larger datasets, team collaboration and, at the top, on-premises deployment and FIX connectivity for trading firms. Because LEAN itself is open source, users can also self-host the engine outside QuantConnect's cloud.
