The Future of Quant Trading

We’re often asked what the differences are between QuantConnect and Quantopian and so we decided to address this question here transparently.

At QuantConnect we have a vision for the future of quant trading. We believe quantitative trading will be the primary investment vehicle of the future. We plan to be the open source, community driven vehicle which makes this future a reality.

Our community is building the most powerful, flexible and encompassing algorithmic platform in the world. Our system is fast, extensible and can support any asset class or market. It can work on a single desktop or as part of a massive cloud cluster. For us, this is incredibly exciting and we imagine a financial future powered by Lean. Hedge-funds, mutual funds, brokerages and individual traders can use our open source Lean platform to power their automated research and trading. Do you want to be part of the future?

The folks at Quantopian have built an interesting hedge-fund, and it looks like a pretty good service. We’re looking to show the facts here without opinion and let you choose for yourself.
