QuantStart is a rapidly growing educational platform dedicated to the world of quantitative finance – often referred to as “quant finance” or simply “quants”. It provides resources, courses, and a community forum aimed at individuals looking to understand, develop, and implement algorithmic trading strategies. This article will serve as a comprehensive introduction to QuantStart, covering its history, core offerings, target audience, key features, strengths, weaknesses, and how it compares to other learning resources in the field.

History and Founding

QuantStart was founded by Dr. Ernie Chan, a seasoned professional with a PhD in mathematical finance and extensive experience in the financial industry. Dr. Chan previously worked as a quantitative analyst at firms like Citadel and Two Sigma. Recognizing a gap in accessible, practical education in quantitative trading, he launched QuantStart in 2014. The initial focus was on providing high-quality, detailed walkthroughs of established quantitative trading strategies. Over time, the platform has expanded to include a broader range of courses, tools, and a thriving community. Dr. Chan's background lends significant credibility to the platform, ensuring the content is both theoretically sound and practically relevant. He also authored the popular book, *Quantitative Trading: How to Build Your Own Algorithmic Trading Business*, which serves as a foundational text for many aspiring quants and is often referenced within the QuantStart materials.
