Hmmm, well, let me tell you that the first thing is that no one becomes a master in trading. Till date I have not come across any person who claims to be a master and closes every trade with 100% sure profit every time.
To be considered a master in trading I don't think you need to have a 100 percent success. it just has to mean that the number of times you win is more than the number of times you lose.
Anybody with a very good record like that, that is more winning record can be considered an expert, a master, a professional or whatever name that you wish to classify or call them.
If there is anybody who claims to have a 100% success rate, the person is only a 100% liar.
