Query: Not fair

I have been trading futures and options for 11 years. I have written three books on the subject. This is the worst example of authoring that I have ever seen. There are no real insights into the subject of Foreign Currency Trading. Mr.Wasendorf fails dismally at being objective and goes overboard in promoting his company PFG. I was sorely disappointed. I was really looking forward to additional insight into Foreign Currency Trading.
