I seriously recommend read as few as possible but practice day and night on every market you can find. So I'd suggest one book on each of the following - chart patterns - Thomas Bulkowski / John Murphy candlestick patterns - Thomas Bulkowski / Steve Nison trading psychology - Mark Douglas example strategies - Linda Bradford Raschke / Mike Covel / Mark Fisher / Alan Farley
Many thanks for the reply. I read chart patterns by Bulkowski and I think his books are not easy to read ! I will check the other books
