My 2¢:
Opinions on how to make money trading can probably be divided into two groups: Group 1: Those who say you don’t need to understand what is going on in order to profit from it. This group will tell you to look for a ‘system’ or ‘strategy’ (‘strat’ if you’re cool), back test it, demo it, and then trade it. The common denominator is that the systems/strats/whatever’s are mechanical in nature meaning that the entry and exit signals are based on some kind of threshold that must be crossed. The threshold is either a moving average, a pivot point a previous high or low etc.
The second Group, which is the one I subscribe to, will tell you that you need to acquire a deep understanding of the market and how it ‘works’ in order to develop and cultivate a sound trading methodology. The methodology is developed through trial and error and continuous study and practice. This is the most arduous route because there are no shortcuts, no magic formulas, no thresholds, nothing that absolves the aspirant (yes, I know) from the responsibility of taking complete and absolute control of their decisions and judging the supply and demand situation.
One thing I would alter about D70’s post is that rather than trade 100 (or whatever) number in demo before going live is that instead you trade maybe 1 live for every 5 demo. That is the way I did it and actually continue to refine my methodology that way. When in doubt, demo trade it.
