QuantConnect is an amazing service!!! QuantConnect provides an amazing service with their data and servers and the ability to run algorithms as if I were a hedge fund. I wouldn't be where I am without QuantConnect!!!

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

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.

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.

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
