Quote from AAAintheBeltway:
For a newbie there is no substitute for getting some backtesting s/w and a lot of historical data and crunching it. Find out why oscillators will never work. Find out why MA crossovers will not work to daytrade the ES. Find out for yourself the relationship between stops and profitablity.
I agree. However, I have never even used backtesting software, and not just because I'm technologically inept. Rather, I prefer to scroll back and test "by hand" (visual inspection). I suppose it is a lot like travel. you can take a plane and get there sooner, or you can take the train and familiarize yourself with the details of the landscape. I imagine that both approaches have their pluses and minuses. I just personally favor the scenic route.
As for books, most of them have (unintentionally) taught me what does not work.
