Book excerpt: "An introduction to the basics of short-term trading, including what the floor traders know and how their knowledge affects your trades, is immediately followed by the core principles and strategies associated with the short-term, hit-and-run approach to the market known as "sniper" trading. You'll learn how to measure, quantify, and interpret market data so you can quickly figure out when the market will move and which way it will go. Sniper Trading then takes you through the process of using this information to successfully trade in the stock, options, and futures markets."--BOOK JACKET.
