I recently purchased this book to strengthen my momentum skills. Being somewhat new to TA, it is has came easy having a extensive computer background. I found Prings explanation on oscillators complete but lacks application to daytrading/investing. I met him at a recent show asking him pertinent questions as they apply to the market and trading and he replied...."I need to buy another book". This book is good on how oscillators are made....NOT HOW THEY ARE USED.
