Our Platform

Welcome

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 C# and Python programming languages, making us a truly open platform.

Our Mission

We believe the future of finance is automated, and we plan to be the quantitative trading infrastructure of the future. Algorithmic trading is a powerful tool, and we want to open it up to all investors. For more information on our mission check out our Manifesto.

Security Privacy

You own all your intellectual property and your code. Your code is private by default unless you explicitly share it with the community in the forums or with another team member via collaboration. You are creating valuable intellectual property, and we respect this and wish to make it easier. We limit the QuantConnect staff members who have access to the database. If we ever need access to your algorithm for debugging, then we will explicitly request permission first. For more information please see our terms and conditions.

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 400T 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 makes backtesting and the research environment available for free and provides co-located servers to run live trading algorithms for a small fee. This offsets our costs and aligns our interests with yours, our client. We also work with brokerages to make your live trading free.

You can also see our Videos. You can also get in touch with us via Discord.
