My trading methodology is based in a equilibrium between fundamental analysis/ technical analysis/ speculation and a lot of psychology, trading isn't about how much do you know, the experience and pain play an important roll too.
You can't see the trading as a normal gambling game, it's about probabilities yes, but if you walk in the correct way, you can be a good trader, obviously, being a "Pro Trader" comes with a lot of money burned and some psychological scars.
