Over the past couple of months I have been intensively researching this subject with background reading and even attending a forex seminar - with a view to supplementing my existing income. I do not believe (and neither should you) the hype that: You can just sit down at your pc and start making lots of money with no effort.
So for two quid, I did not expect much. However, I was pleasantly surprised. The author, Mark Boardman does speak a lot of common sense and it happens to fit with what I have experienced so far, that price action with just a few indicators is the way to trade (for me personally anyway). Also by setting the odds in your favour (ie setting your profit higher than your stop loss), mathematically you will make money in the long run.
Sure, this kindle book lacks a lot of detail (what do you expect for two quid), apparently more detail will be given in a forthcoming complete book on the subject. Also, yes Mark Boardman mentions his online seminars (modestly priced compared to most), and why not. You do not learn to drive a car or ride a horse by reading books (sure they may help), so does it not make sense that to be more successful at forex you follow a successful trader demonstrating what they do? And practice, practice, practice - its the same with anything in life.
So it is well worth a read, but don't expect it to answer all your questions.
