Description:WARNING!!!I found this book to be very well written and appeared to be carefully put together. That is until I got to Chapter 6 in which I found glaring mistakes. Case in point, the description of the bull put spread is written such that the author has used different strike prices throughout his example, resulting in an unreadable, confusing mess. This is unfortunate as I think that if the author or his publisher had taken the time to proof the book, these examples should have been corrected. Save your money and find another book to use as an introduction to options trading.
