I read one book by Daryl Guppy many years ago when I first had an interest in shares and at that time most of the concepts were interesting to me but now have forgotten most except for his Guppy's Multi-Moving Average. He also writes a regular column for CNBC here.
I have read his book Share Trading - An Approach to Buying And Selling. A family friend put me onto him after I racked his brain over share trading and he just told me to read that book. But I have noticed he does not get much mention in here. http://en.wikipedia.org/wiki/Daryl_Guppy
