Alex stayed the course and helped me… Alex stayed the course and helped me with an issue that turned out to be not QuantConnect’s fault. But it turns out his idea led to a resolution. Much appreciation!!!

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.

Complex, difficult API, slow backtesting Extremely slow backtesting and very complex APi with bad documentation - be ready to spend many hours trying to understand the overly complex API that is changing all the time. And did I mention that support costs? So if a anything is complex you won't get answers from the staff unless you PAY them. I give them 2 stars as they have reasonably reliable data. The platform itself is only worth one star. note: if you ask about slowness or any other thing negative on their forum they delete the posts.

I wasn’t a programmer I wasn’t a programmer, took a python basics course on youtube and their free bootcamp course and I was surprised how quickly I picked up object oriented programming and algorithmic trading coding on their platform. The stocks data is free up to seconds timeframe, after a long research on competitors I choose quantconnect and it was up to my expectations.

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!
