It's not that we don't know what to do, it's that we can't do what we know. I'd wager that most traders at this point have read/heard about the 10 commandments of trading - they're mostly the same no? Cut your losses, let your profits run, etc....what's changed in 2,000 yrs? After the first 10 years of my trading, I realized that the solution is to actually incorporate them in into your trading. Too many traders look for rules when they already know them. IMHO, one should be practicing how to actually follow the rules they know...rather than seeking the new holy grail of trading rules. Trading rules haven't changed, not since humans roamed the earth.
