Very easy tool to use for creating, backtesting, optimizing and going live with a trading strategy. I went from concept to live trading in less than a month. It probably helped that I have a programming background. But really Quantconnect made it so easy and simple.

QuantConnect has been an absolute game-changer for my algorithmic trading journey. What sets this platform apart is its robust infrastructure and comprehensive backtesting capabilities - honestly, I haven't found anything else on the market that offers this level of functionality for algorithm development. The backtesting engine is incredibly powerful and has been helping me refine and improve trading algorithms. Being able to test strategies against historical data has saved me countless hours and potential losses. The platform handles complex scenarios and provides guided results to make informed decisions about your strategies. What I appreciate most is the ability to iterate quickly and see real results which has dramatically accelerated our development process for our startup.

I really like that QC is both beginner friendly (has instructive bootcamp classes, intuitive UI for coding and viewing plots/results, and extensive built-in functions) but also supports complex designs, i.e. no limiting assumptions or constraints on the user’s algorithms. The parameter optimization tool is really convenient and connecting to IB has been smooth and reliable. QC makes it possible for anyone (that can program) to explore algorithmic trading.

Everything a retail trader needs to start building algos right out of the box. Supportive community. What more could you ask for?

I recently purchased Quantum Connect, and I couldn’t be happier with my experience. This product is exactly what I paid for. It delivers on every promise. The customization options are a standout feature. I was able to fine‑tune everything with a short learning curve, to perfectly fit my needs. Every detail feels intentional and high‑quality. If you’re looking for reliability, precision, and a product that lives up to its description, I highly recommend Quantum Connect. It’s worth every penny!

I have been an early user of QuantConnect since 2014 and the platform along with the team consistently managed to exceed my expectations. In particular, with the heavy lifting they did with handling Terabytes of minute-resolution options data (as well as tick data for equities and futures) all easily available in the cloud. A fairly extensive test coverage of the open-sourced Lean engine brings confidence in things working as expected. While there is no such thing as perfectly realistic backtesting, QuantConnect comes close enough with their reality modeling efforts. The Algorithm Framework also facilitates modular thinking about the building blocks of an investment/trading strategy. Overall - in my opinion, the best starting point available for serious and thoughtful diving into quantitative finance.

I am delighted to find Quant Connect for my back testing and live testing needs. Really easy to seamlessly integrate your code and to connect to brokers or other data providers for your back test or live testing needs. Customer support is an A+ also with fast and personalized responses. Highly recommend Quant Connect.

We’ve been using QuantConnect as our main and only quant platform for ca 5 years. We’ve ended up on QC after years of trying to find a platform with a comprehensive scope, supporting an algorithmic trading pipeline end to end. We’re particular fans of what QC calls the Algorithm Framework, which allows for a modular separations of concerns based setup.
