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!

QuantConnect.com review - SLOW QuantConnect review : QuantConnect is one of the great platform to implement automated quant trading strategies. However what makes me unhappy with this platform is that it is very slow at times. Refer to screenshot link below showing the wait time more than 1800 seconds. https:// ibb. co/ BLBg52D

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.

Shady site Shady site not sure if the team behind are trustworthy with holding your algos data. I found other frameworks like backtrader that are easier to pick up and get working with quickly than LEAN. LEAN is poorly documenting making learning a huge hurdle. Also, I question the stability of their site because of the amount of bugs you can find in their UI and some that I encountered in plotting during backtrading. If you need an online IDE, Quantopian is far more reliable and documented and quicker to work with but still could have issues with data privacy.

Accelerator of analysis! Really nice platform to boost your algorithmic trading.
