I normally felt aggressive and sad when I made loss in forex trading as a newbie, but now, I have been able to adjust how I feel when I loss in my trading because I have learnt to follow money management rule at all time. Money management rule helps me to minimize my loss in every trade I make. and i think aggressive mind can be dangerous and sometimes it can destroy our strategy ..we should be cool all the time ..over excitation and wrong decision can ate all of our money so quickly .if we can control our geed and doing aggressive then it's fine i think
