It's all here and you have the forums.
If you had to buy 1, I would say get Steve Nison's book "Japanese Candlestick charting". However, there are a lot of patterns in there not 100% related to forex as it's stocks as well but lots and lots of explanations to drill it home. ALso, when you receive the book, rip out all the end pages on indicators
Oh, no actually maybe leave them there because then you can sell it back to someone else 2nd hand on eBay.
