Book Review: Inside the Black Box

You have probably already heard about such terms as black box, expert advisors, quant (quantitative) trading, and if not, you would do yourself a disservice if you don't do some research about it. When talking about a black box in the domain of trading people refer to tools, usually software, that allow automated trading. It is called a black box because it is not possible to see inside it, or in other words, to understand their mechanism, but in reality, they are nothing top secret. Inside the Black Box will show you the main components of a black box, explaining how they work, what are the advantages and disadvantages and the criticism of their use in the market.

All components are explained in detail so that the reader can understand what are the functions, dependencies and connections between components.

Part 3 opens the eyes of a potential investor interested in quantitative trading. The author warns about the risks related to quant strategies, lists the criticism connected to quant trading and explains how to evaluate quants and quant strategies.

Part 4 is dedicated to high frequency trading, in short HFT, a topic that usually goes together with quant trading. High frequency trading is introduced with its basics and divided in high-speed trading and high-frequency trading, closing with the controversy regarding this trading system/method.
