Industry standard tools, thriving community, passionate team
I joined QuantConnect back in 2018 as a hobbyist trying to learn the basics of algorithmic trading. Three years later, and countless hours spent on LEAN and QuantConnect, I can only speak highly of this platform that helped me make the career change I was looking for.
* Complexity: This is not some drag-and-drop platform to build out-of-the-box trading bots. Yes, the API takes some time to learn but I think that should be expected of any serious software that offers this level of flexibility and robustness.
* Community: I've seen the community grow over the years and become this amazing mix of backgrounds that share creative ideas and help each other.
* AlphaStreams Marketplace: I've personally been developing and submitting alphas to the marketplace from the beginning, some of which got licensed by clients. The criteria to enter is strict to ensure statistical significance of results and competition is fierce, but this growing marketplace has the potential to revolutionize the open-source quant scene by providing a stable income to alpha developers.
* Team: I've worked closely with the QuantConnect team over the years and their professionalism and integrity are out of the question. Not only I trust them with holding my algorithms, but so do my institutional clients for whom I work in QuantConnect.
All in all, a fantastic platform for anyone looking for institutional-grade software, a thriving community of like-minded algo traders, and a hard-working trustworthy team of professionals.
