Query: Book has useful info, but...

I have been trading for a year now, and still being new, I am always looking for new ideas. Farrell's book gave me insight into how markets work. However, his system, in my humble opinion, has it's drawbacks. The "specialists" have the upper hand in ALL matters of knowing which orders are coming in and after using his system (albeit with a minimum of cash), I find the risk to be just as great, if not sometimes greater. Overall, I feel that Farrell's system can not be exploited to its potential by the average day-trader, although I like the premise behind his strategy to "hit singles, not home runs." But, then, what do I know? This guy is two years younger than I am, and he's 1000x as rich!
