1) momentum is a very important trading concept whilst MACD is a very useful oscillator type indicator to identify overbought and oversold situations, and thus change of s/t trend, a TA tool which helps traders not to buy high sell low, especially in a day trading environment.
2)the author had written a very easy reading book in a very friendly and understandable way.
However, I can hardly agree that:-
1) the author presented momentum as a surefire weapon in the highly volatile market and can be used alone
2) the author did keep it simple, but it's too simple all the way throughout the 180+ page content and he should lead the readers from simple concept to complicated application or even teach readers how to improve its accuracy with simultaneous usage of stochastics or RSI or...In fact, there are many examples/charts illustrated by the author which showed extended period of divergence with very unfavorable price moment that might have already kicked an investor out of his position, in case he/she did not have a strong brief on his/her position but by sheer reliance on MACD.
As a professional trader, I cant recommend this book to anybody. The quality of this is just so far below the author's own classic "Investment Quotient" which the author's strength (trading behavioral psychology) rests solidly upon.
however, it comes across as too simple. the methods that are discussed here does not really give you the confidence that they are sufficient for you to trade properly.
another book by this author on the psychology part of trading, 'IQ the investors quotient', is a much better and strongly recommended read. in terms of market momentum, martin pring's 'trading with oscillators' is more useful, and just as easy to read.
