Making Quant Analysis and Trading accessible to everyone I knew about QuantConnect when I was desperately searching online for Options Historical data in the US markets. Everything else I found was expensive and required me a lot of manual handling. Not to say they weren't realistic at all (i.e. didn't consider company splits, adquisitions, etc.). QuantConnect and the open source lean framework made it very easy to implement trading algorithms (with a results very close to what I get in Interactive Brokers; including fees, splits, dividends, option assignments, etc.) at a very cheap cost (you just pay for the cloud computing resources). Being open source makes it very easy to figure out how to do things, however, they have interactive tutorials that will prepare anyone with basic development skills to implement real-live trading algorithms. Not to say the community is awesome and very helpful. QuantConnect is easily escalable for both small individuals and large corportations. Many organizations and hedge funds use it for their analysis and live trading.

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

Amazing platform Amazing platform! Simple to use. Gives you all the financial datasources you can think of at your fingertips. The ability to create unlimited algorithms. Creating algorithm takes just a few lines of code. Connect your favorite brokerage firm in minutes. Deploy in minutes. Great support and documentation. If you are not sure how, just ask Mia, there new chatgpt like tool, that will write the code for you or answer any question you may have.

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!

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.
