This is the best platform for… This is the best platform for individuals. I seldom subscribe to 'pro-account' things, but I did for this one. The dirty stuff like data cleansing, backtesting framework, error handling is done by them and I can focus on the fun stuff, printing money.

Great technology, accessible team, invaluable supporters of the ecosystem QuantConnect has been an invaluable partner for my personal trading and for a university class that I teach. The community is incredibly supportive, and the leadership team are accessible which is almost unheard of in trading platforms these days. In my class, my graduate level students have been able to personally engage and implement constructs like Fama French factors, and QuantConnect has been an active supporter to facilitate my students learning. It's incredible to join the community, have access to a variety of detailed trading algorithms, instructional videos, and see my students feel confident implementing week-to-week. I don't think there's anything like QuantConnect out there today, and I'm a big supporter of their efforts. I can't imagine my own trading or teaching my class without it!

Long time believer, first time promoter. I've been using Quantconnect for about two years but they've just released new capabilities for options research, based on user feedback, that prompted me to add a review. They listen to, care about, and build new features for their users (free features). Highly recommend.

Making Quant Analysis and Trading accessible to everyone I knew about QuantConnect when I was desperately searching online for Options Historical data in the US markets. Everything else I found was expensive and required me a lot of manual handling. Not to say they weren't realistic at all (i.e. didn't consider company splits, adquisitions, etc.). QuantConnect and the open source lean framework made it very easy to implement trading algorithms (with a results very close to what I get in Interactive Brokers; including fees, splits, dividends, option assignments, etc.) at a very cheap cost (you just pay for the cloud computing resources). Being open source makes it very easy to figure out how to do things, however, they have interactive tutorials that will prepare anyone with basic development skills to implement real-live trading algorithms. Not to say the community is awesome and very helpful. QuantConnect is easily escalable for both small individuals and large corportations. Many organizations and hedge funds use it for their analysis and live trading.

Quantconnect is a great resource for quantitative strategy deployment Quantconnect is a great resource for the deployment of algorithmic and quantitative trading ideas. Once a user is familiar with the event-driven architecture of the trading platform, bringing strategies into action which align with a trader/investor's view of the financial markets can be carried out with great efficiency. The documentation for the trading platform is comprehensive and helps with strategy tuning. Then there's backtesting and optimization which are pretty great to tinker with, amongst other resources user can interact with. Sometimes the website is slow, but never for a prolonged period, however it is still a nag. Overall, I'm delighted with the product; looking forward to more deployments and engagements with the community!
