Trading as a Business

As a full time professional trader who designs trading systems, I have found this book to an invaluable reference. It is a straightforward, comprehensive treatment of the art and science of designing, testing and
evaluating trading systems/strategies.
Examples are given for Tradestation, which I don't own or use but they are simple enough to understand and transport to some other trading program that supports historical simulation and backtesting.
