Where did you get this analysis? I'll be happy if you put the source to convince me that the analysis is trully happen.

I mean, I never got this information because if I got it then I'll have many times before I decide to be full time trader.

I read a trading book and the author just called that trader is a cursed profession and I just thought that it is true because I've felt it.

A trader prediction only have 70% if he really sure about his prediction. They never have 100% a chance to get profit about his prediction. Also, trading is always hard, just a fool people who admitted that earning money in trading is easy.
