A trader's dream: Sitting with a cool beer on the beach while his computer breeds money with automated trading. Can this actually work? It depends. This textbook covers the "algorithmic" part of algorithmic trading - not with "technical indicators", but with modern methods based on solid math and statistics. The author has developed so far about 600 trading systems for institutes and private traders, and writes about his experiences on the blog "The Financial Hacker". In his book you'll learn the tricks and traps, which methods work and which don't, and how to develop a trading system from the first idea until going live. Many example systems are presented with new trading methods, such as spectral analysis and statistical filters. You're introduced in proper testing with solid Walk Forward, Montecarlo, and Reality Check methods. All examples come with code ready to run. No matter if you are a beginner or a seasoned algo developer, this book will provide new insights into algorithmic trading. "Johann Christian Lotter has succeeded in writing an interesting and, above all, honest book: Instead of picture-book examples, it presents working code, instead of pink rhetoric, hard truth. All prospective traders interested in algorithmic trading should take a look at this book." TRADERS' August 2016
