I would start with John Murphy. Technical analysis of the financial markets.

There are a zillion TA books out there but I think Murphy is about as good a place as any to get the basics. He explains many different methods such as chart patterns, oscillators, moving averages etc.

Once you get the basics down you may want to look for something more specific. A lot also depends on the time frame you are interested in. Day trading, swing trading, long term trades etc.
