fibonacci traders

Hi all,

I am after some reading material regarding Fibonacci retracements, projections, etc. Many of the books I have on TA cover this topic as an introduction only but never go too deeply in to it's use for trading purposes. What I currently use, am familiar with and have some degree of success with, is support and resistance lines in determining some likelyhood of a trend coming back to a particular point...when it turns. Fibonacci is something that goes a little further than that and I am very keen to get a grasp of it's use on a more advanced level.

I know alpha uses it quite a bit but many others do also, so any help on this is much appreciated.

Thanks in advance.

Cheers
