Professional trader know the methodology of trading. Most skillful trader didn't trade with emotion they have their predetermined exist plan and have good trading plans.
The real experts will never reveal their secrets. That's just my opinion.
There is no big secret, if after seeing my thread you still think only the top city boys know how to play the game, then forex isn't for you. follow the rules that is the key. the method plays a role but if you do not follow the rules you won't be successful no matter how good your method. you have to be a absolute genius to win by not playing by the rules
