Quant finance is becoming the most common way to invest, yet most investors have no way to compete due to the massive barriers to entry.

The future of quant finance will be radically open-source; why should millions of engineers re-invent the same brokerage and data integrations over and over again?

These connectors should be done once and open-sourced. Like device drivers for your mouse or keyboard, you should simply plugin a brokerage/dataset, which will work to a standard interface.

Yet funds and vendors keep these locked up because they're a "competitive advantage" to prevent other funds/vendors from starting.

We're breaking that cycle.

QuantConnect has just open-sourced 15 brokerage integrations. It represents roughly seven years of work from a dozen engineers. The Interactive Brokers connector has executed $20B in notional volume across 200,000 live strategy deployments.

Our mission is to create a Linux for quantitative finance. You will never need to write another brokerage connection or data set integration because they'll all be open-source and free.

Let's make quant finance more transparent and accessible.

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!

I have been using QC since 2018, the platform is great to research, implement and run algo trading strategies. The team is amazing, they keeps delivering new features and improving the trading engine, everything is open source and it works like a charm. Big fan!

Looks interesting.

I recently came across this newer platform Blankly with similar goals, it has great docs and easy to get started

Have been using this for the better part of the year, probably the best backtest and live platform I've seen. Love it!

Thanks for this!
