Cloud Platform


QuantConnect is an open-source, community-driven algorithmic trading platform. Our trading engine is powered by LEAN, a cross-platform, multi-asset technology that brings cutting-edge finance to the open-source community. We support Python and C# programming languages.

Our Mission

Quantitative trading infrastructure should be open-source. Millions of financial engineers rewrite the same infrastructure and then keep their work closed to make it harder for competing trading firms. We take a radically open approach to quant finance and let our users focus on alpha, not infrastructure.

The future of finance is automated and we are the open-source infrastructure to power this future. Firms choose our open-source platform as it provides a 10-100x improvement in time to market and substantially reduces the risk of developing your quantitative tools. As our brokerage and data integrations expand, this leverage will be more exceptional.

Everyone should have access to quantitative finance. Algorithmic trading is a powerful tool and we want to open it up to all investors. We do this with transparent, scalable pricing that allows all investors to access quantitative finance. For more information on our mission, check out our Manifesto.

Data Library

We provide an enormous library of data for your backtesting, research, and live trading. The library includes data for Equities, Options, Futures, CFDs, Forex, Crypto, Indices, and alternative data. The library is roughly 400TB in size, contains trade data that spans decades into the past, and comes in tick to daily resolutions. View the Dataset Market to see all of the datasets that we have available, including their respective start dates, end dates, and resolutions. The following image shows the integrated data providers:

Business Model

QuantConnect provides cloud infrastructure as a service, similar to many cloud compute vendors. We encourage quants and start up firms to grow within our ecosystem to keep our pricing accessible to individuals and small firms.

For companies interested in running QuantConnect on-premise, we can install it within your corporate firewall and help you get set up with financial data. We charge a set up and maintenance fee for these installations.
