Introduction

LEAN is a radically open-source algorithmic trading engine. Used by a community of 100,000+ quants, engineers, and scientists, it is wholly modular in its design, with each component pluggable and customizable to make it suitable for every industry participant. Originally built and currently administered by QuantConnect, LEAN shifts the paradigm of power in finance to the individual and gives users the freedom to execute their ideas in research, backtesting, and live trading. Together, we endeavor to build a new infrastructure for the future of quantitative trading.
