Trading on the financial markets requires the mastery of many subjects, from strategies and the instruments being traded to market structures and the mechanisms that drive executions. This second of four volumes explores them all. After brief explanations of the activities associated with buying and selling, the book covers principals, agents, and the market venues in which they interact. Next come the instruments that they buy and sell: how are they categorized and how do they act? Concluding the volume is a discussion about major processes and the ways that they vary by market and instrument. Contributing to these explanations are visual cues that guide readers through the material. Making profitable trades might not be easy, but with the help of this book they are possible. This title explains the basics of investing and trading, markets, instruments, and processes. It presents major concepts with graphs and easily-understood definitions. It builds upon the introduction provided by Book 1 while preparing the reader for Books 3 and 4.
