nvest - knowing what I know now (and understand), I would pick this one book that I reviewed on TL:
http://www.traderslaboratory.com/for...tion-1561.html
Which is for:
Japanese Candlestick Charting Techniques, Second Edition by Steve Nison
Now, there is one caveat to why I would recommend this one... I now 'get' what candlesticks do... I understand what the candles are 'saying'. It's much more than hunting for shapes, which is what many noobs do and then claim that candles do not work...
So that's the book that I would have by my side if only one.
