This is the best platform for quantitative trading I have seen in my 16 year career as a quant. It is an end-to-end platform with data, backtesting and production i.e. live trading capability all in one. Topped up with a seriously active community sharing rich resources and ideas for algorithm development which accelerates the learning curve for both beginners and experts alike. Never have I seen a vision so balanced and pure to develop a product that not only helps aspiring quants but quant hedge funds to immediately hit the road running in developing their strategies using the platform with an affordable and very pleasant user experience. I am launching a quant hedge fund using QuantConnect and I have Jared, the founder and his team to thank as they have done an astounding job. It is with sincere gratitude that I post this comment and I hope QuantConnect becomes the future of the entire Global Quant community!
