In the book, Lewis trains his focus on high-frequency trading, a type of rapid computerized trading that accounts for about half of the shares traded in the US.
This type of trading uses powerful computers that can move in and out of stocks within a fraction of a second, giving high-frequency traders an extra millisecond of time to 鈥渂eat鈥 other investors in a trade. This allows high-frequency traders to buy stocks and quickly sell them back at higher prices 鈥 a fraction of a millisecond that can reap hundreds of millions of dollars.
