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 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!

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

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.
