"Flash Boys: A Wall Street Revolt" is a book by Michael Lewis that explores the world of high-frequency trading (HFT) on Wall Street. Lewis introduces readers to a group of traders who discover that the stock market isn't as fair as it seems. They find that high-frequency traders are gaining an unfair advantage by using advanced technology to execute trades milliseconds faster than others, allowing them to manipulate market prices.
The narrative centers around a trader named Brad Katsuyama, who, frustrated by the unfair practices within the market, decides to take action. He assembles a team to create a new exchange called IEX, which aims to provide a fair trading platform that counters unethical practices in HFT. Through their efforts, they expose the complexities and flaws in the modern financial system.
