It looks we both are "newbies" here (at least based on post-count ). A good book on the subject seems to be: "Algorithmic Trading and DMA" by Barry Johnson. I have not read it myself, but it has some fairly decent reviews on Amazon.
A book that has not been published yet, but looks promising is: "An Introduction to Algorithmic Trading: Basic to Advanced Strategies" by Leshik and Cralle.
But, as you, I would definitely want to hear what the seasoned pros here recommends.
